GLM 5.3 High· move 1

Played e4

e4e2 → e4

Best by test, baby. Try to keep up.

GLM 5.3 Flash High· move 1…

Played c5

c5c7 → c5

Sicilian it is — let's make this a knife fight, not a gentleman's stroll.

GLM 5.3 High· move 2

Sicilian. Best move: Nf3 or Nc3. Nf3 is fine.

Played Nf3

Nf3g1 → f3

The Sicilian, huh? Bold choice — I hope you brought a good memory for theory.

GLM 5.3 Flash High· move 2…

Sicilian, Nc6 or d6. Standard: Nc6 or d6. I'll play Nc6.

Played Nc6

Nc6b8 → c6

A knight comes out to play — the Sicilian just got interesting!

GLM 5.3 High· move 3

Sicilian. Best move: d4 (Open Sicilian) or Bb5. Standard is 3.d4.

Played d4

d4d2 → d4

Time to open things up — hope you've read your theory, because I have.

GLM 5.3 Flash High· move 3…

Standard Open Sicilian: play cxd4.

The Open Sicilian calls for capturing the center — cxd4 it is.

Played cxd4

cxd4c5 → d4

You opened things up — I'll just take what's mine, thanks!

GLM 5.3 High· move 4

Position: 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4. Wait, but the board shows d7 still there and black has d-pawn... Actually FEN shows pawn on d7 and pawn on d4 — Black had c5 pawn captured d4. Material says White down 1, so Black captured the d4 pawn. Best move: Nxd4 (Open Sicilian main line).

Played Nxd4

Nxd4f3 → d4

Thanks for the gift — I'll take that pawn back and center my knight where it belongs.

GLM 5.3 Flash High· move 4…

Sicilian Open, 4...Nf6 standard. Or Nxd4!? No, Nf6 is best.

Played Nf6

Nf6g8 → f6

Developing with tempo on that greedy knight — my d-pawn sacrifice is about to pay dividends.

GLM 5.3 High· move 5

This is the Open Sicilian, 4...Nf6. Standard move is Nxc6 (main line) or Nb5. Main theory: 5.Nxc6 bxc6 6.e5 etc. Nxc6 is the main move.

Played Nxc6

Nxc6d4 → c6

Trading down in the center — your knight was getting too comfortable on c6.

GLM 5.3 Flash High· move 5…

White played Nxc6, offering a trade... wait, White's knight captured on c6 and it's Black's move 5. So the knight on c6 is White's. We can recapture with bxc6 or dxc6. Recapturing is standard. bxc6 opens b-file; dxc6 damages... typical Sicilian: after Nxc6, bxc6 (or dxc6). Both fine; dxc6 keeps pawn structure? Actually in Open Sicilian with d4 played, Nxc6 bxc6 is normal. Recapture with bxc6.

My knight avenged with a pawn recapture — take that, pony-snatcher!

Played bxc6

bxc6b7 → c6

You took my knight, so I'll take yours — with interest on the pawn structure!

GLM 5.3 High· move 6

Position after 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nxc6 bxc6. Standard theory: 6.Bd3 or 6.Qd2... Actually the main line here: 6.e5 is the known best move (Qxd7+?? no). Standard: 6.e5 Nd5 7.Qxd5? No — wait, 6.e5 Nd5 and it's known that cxd5 isn't possible... Let's check: 6.e5 Nd5 7.Qxd5! cxd5?? illegal since pawn on c6 can capture d5 — c6xd5 yes, so Qxd5 cxd5 wins queen? No, Qxd5 cxd5 just trades queen for knight — bad. Main line: 6.e5 Nd5 7.Bc4 is playable. Also 6.Bd3 aiming. Actually known line: 5...bxc6 6.e5 Nd5 7.Qxd5?? no. 7.Bc4 Nb6 8.Bb5. Standard theory says 6.e5 is best. Let me verify e5 is legal: yes, listed. Also check Qxd7+?? Qxd7 Kxd7 loses queen. Avoid. Play 6.e5 Nd5 7.Bc4. Good.

The position is a known Sicilian structure. Black just recaptured with the b-pawn, leaving their center slightly weakened. The strongest move is the central thrust **e5**, kicking the knight and gaining space — if the knight retreats to d5, I'll follow up with Bc4 eyeing that loose square.

Played e5

e5e4 → e5

Central pawn thrust — your knight's rent just went up, time to move out!

GLM 5.3 Flash High· move 6…

White played e5 after 5. Nxc6 bxc6. Black to move. Best: Qa5+ doesn't quite... Qa5+ hits e5? Qa5+ checks king on e1 along a5-e1 diagonal: a5, b4, c3, d2, e1 — d2 empty, so yes check. But standard move is Qa5+ then Qxe5+ wins pawn. Actually with pawn on e5, Qa5+ Qd2/... Let's think: Qa5+ Qe2? Blocking with Qe2, then Qxe5+ Qxe5 loses queen? No: Qxe5+ Qxe5 — black queen takes pawn with check, white queen recaptures, trade queens fine, black won a pawn? e5 was white's pawn; Qxe5+ Qxe5 trades queens, black gains the e5 pawn. Material: even before; after, black up a pawn. But white could block with Qd2 or Be3/Qe2/Be2/Ne2... knight is off. Blocking with Be2 or Qe2 or Qd2 or Be3? Bc1 can't reach d2... Be3 doesn't block (a5-e1 diagonal: b4,c3,d2). Blocks: Qd2, Qe2? Qe2 not on the diagonal. Only d2 blocks, or interpose... only d2. Qd2 blocks, then Qxe5? Qa5xe5: a5-e5? Not a line. Hmm Qa5 to e5 is along rank 5: a5-b5-c5-d5-e5, but e5 occupied by white pawn — yes Qxe5 along rank, and it's check? e5 queen attacks e1 via e-file: e4, e3, e2 empty — check. Then Qxe5 Qxe5 trade, black up a pawn. Wait, does Qd2 defend e5? Qd2 attacks e5? d2-e5 not a line. So Qa5+ Qd2, Qxe5+ wins a pawn? After Qxe5+ white plays Qxe5? Qd2 doesn't attack e5... actually Qd2xe5 not possible. White must respond to check: Qxe5+ check from e5 to e1. White blocks/captures: nothing on e-file; Ke1 can move, or Qe2 interpose then Qxe2? Wait Qxe5+ is check on the e-file; white interposes Qe2, then Qxe2#? Qxe2 Qxe2 — queen trade, black up a pawn. Or white plays Qd2-f4? No, must address check. White could play f4 pawn block? f2-f4? Check is along e-file; blocking with f4 doesn't help. Be2? Bf1-e2 interpose, then Qxe2 Qxe2? Bxe2 possible... anyway black wins pawn at least. Alternatively simpler: d6!? or Qc7. Actually the standard theory: 5. Nxc6 bxc6 6. e5 Qa5+ 7. ... this is a known trap-ish line. Common: 6...Qa5+ 7. Bd2? no bishop can't. Actually theory: after 5.Nxc6 bxc6 6.e5 Qa5+ 7.Nc3?? doesn't exist... 7. Qd2 Qxe5+ winning pawn. Yes, this is a known line where black regains with interest. Alternatively 6...d5 hitting e5? d5, exd6? No exd5? e5 pawn takes d6? en passant? exd6 e.p. White pawn on e5, black plays d5 — en passant available: exd6. So d6 is better maybe. I'll play Qa5+.

Your pawn stormed forward but left your king wide open — time to collect rent with interest!

Played Qa5+

Qa5+d8 → a5

Check! My queen's calling — and your e5 pawn is about to be evicted.

GLM 5.3 High· move 7

Position: White in check from Qa5. Legal moves: b4, c3, Nc3, Nd2, Bd2, Qd2, Ke2. Best is Qd2 offering trade; or Bd2. Qd2 trades queens after Qxd2+ Bxd2... actually Qd2 Qxd2+ Bxd2 — good, wins a tempo? Bd2 also. Qd2 is natural: if Qxd2+ Bxd2, White is fine and e5 pawn is defended... e5 pawn isn't attacked by queen anyway. Qd2 vs Bd2: Qd2 allows trade; Bd2 offers trade too. Qd2 is stronger — develops queen, invites trade into better structure (Black's doubled c-pawns). Also c3 defends and blocks. Qd2 best.

Played Qd2

Qd2d1 → d2

Your majesty's phone call ends here — trade queens or retreat, either way I'm keeping the penthouse.

GLM 5.3 Flash High· move 7…

Position: White played 7. Qd2 offering queen trade. Black can consider Qxd2+ Kxd2? Wait, after Qxd2+ Kxd2, White king on d2 — but White's queenside pieces... Actually trading queens here: after Qxd2+ Kxd2, Black has good structure? bxc6 is weak-ish. But White's king on d2 blocks development; actually in the Nimzowitsch/Sveshnikov line, 7. Qd2?! allows ...Qxd2+ 8. Kxd2 and Black is comfortable with better structure? Black has doubled c-pawns but knight vs bishop... Actually common line: 6... Qa5+ 7. Qd2 Qxd2+ 8. Kxd2 cxd4 — wait no, knight already traded. Let me count material: equal. Also Qxe5+!? — is it safe? Qxe5+ Qe2? No, White queen on d2, so Qxe5+ and White could trade... Qxe5+ then Qd2xe5? Queen on d2 can't reach e5 (d2 to e5 not a queen line? d2-e3-f4... no, e5 is not on a line from d2). d2 to e5: no. So Qxe5+ gives Black a pawn? Check: Qa5xe5, is e5 defended? e5 pawn attacked by Black queen; defenders of e5: Qd2? No. Bf1? No. Nb1? No. d4 pawn gone. So Qxe5+ just wins a pawn, and check forces... after Qxe5+ White must block or move king: Be2, Be3? c1 bishop to e3 blocks check (e3 blocks a5-e5? No — check line is e5-e1. Interpose on e2 or e3? e3 is between e5 and e1: yes e3 interposes. Or Be2, Ne2? Nb1-e2? No, b1 to e2 not knight move... actually b1-d2-e3... b1 to c3 or d2, so Ne2 not possible. Qd2 can't block. So Be2/Be3/Qe2? Queen d2 can't go to e2? d2-e2 yes! Qe2 blocks. Then Black is up a pawn with queens on. Is Qxe5 safe from Qe2 attacks? Qe2 attacks e5. Then Black can move queen or trade: Qxe2+ Bxe2. Trading queens up a pawn — great for Black. Or after Qe2, ...Qxe2+ Kxe2, Black up a pawn. But wait — does White have a zwischenzug? After Qxe5+ (it's check), White must respond to check. Qe2 forced-ish. Then Qxe2+ Kxe2. Black up a clean pawn. Also check Qa5xe5 legality: a5 to e5 along rank 5, path b5,c5,d5 empty? c6 pawn is on c6 not c5. Yes, legal. And Qxe5+ is even check. Any better? Qxd2+ Kxd2 also fine but Qxe5+ wins a pawn. However, after Qxe5+ Qe2!? White might prefer Qe2 keeping queens; then Black plays ...Qxe2+ Kxe2 (or Bxe2). Then Black a pawn up, plus d7-e7 can develop, castle long? King went to e2. Black is clearly better. Actually also consider ...Qxe5+ 8. Be3 — blocks on e3, attacks? Be3 attacks e5 queen. Then Black retreats, still up a pawn but queen may be harassed: after Be3, queen e5 attacked by bishop; also f2-f4 later. Black could play Qxe3+ fxe3? Qxe3+ fxe3 loses queen for bishop — no. After Be3, Black plays Qc5 or Qd5 or Qb4+? Check: Qb4+ c3? c2-c3 blocks... Qb4+ attacked by c2 pawn? c2 attacks b3 and d3, not b4. Qb4+ then Bd2? Hmm. Simpler: after Be3, Qxe3+! Qxe3? No — Qd2xe3? d2 to e3 yes! So Qxe3+ fxe3 fine? f2xe3 recaptures queen — no, Black queen would be captured. Wait Qxe3+ — Black queen takes bishop on e3, White recaptures with fxe3 or Qxe3, winning queen for bishop. Bad. So after Be3, Black should retreat: Qc5 hitting? Qc5 attacks c2? and f2. Or Qd5 attacking f7? No. Qc5 attacked by b2? No. Then Black up a pawn, fine. Or even Qxe5 trick: no. Wait also after Qxe5+ 8. Be3, there's Qd5!? or ...Nxe5? knight f6 can't take e5, it's own queen there. Hmm, actually Black's queen on e5 with Be3 pinning-ish? Not pin. Black could consider Qxe4? No e4 gone. Also after Qe2 by White, instead of trading, Black could keep queens: Qc7 or Qd5 etc. But Qxe2+ is simplest: up pawn, better structure? Black has doubled c-pawns but solid. Alternatively ...Qxe5+ 8. Qe2 Qxe2+ 9. Kxe2 (or Bxe2) — either way Black wins a pawn. Could White instead respond 8. Kd1?? No, in check from e5? Check line e5-e1; king must move or block. Kd1? e5-d1? e5-d4-c3-b2-a1 diagonal, not through d1. d1 not attacked, but king on e1 in check must leave e1 or block; Kd1 legal? d1 attacked by queen e5? No. So Kd1 possible. Then Black keeps pawn, maybe Qe4 or f6? Fine. So play Qxe5+.

Your penthouse view is lovely, but I'm raiding the pantry first.

Played Qxe5+

Qxe5+a5 → e5

You kept the penthouse — shame I'm foreclosing on your pawn and taking it with interest.

GLM 5.3 High· move 8

Position: White in check from Qe5. Legal moves: Qe3, Qe2, Kd1, Be2. Which is best? Qe3 trades queens. Qe2 blocks but is pinned-ish? Qe2 blocks, then Black queen can retreat or... Qe2, Black could play Bb7 or Qxe2+... queen e2 facing queen e5. If Qe2, Black Qxe2+ Kxe2 — trades queens anyway. Qe3 forces trade: Qxe3+ Bxe3/Kxe3... Qxe3+ then fxe3? f-pawn? f2 pawn can take. Qxe3+ fxe3 or Bxe3? Bc1 can't take e3... fxe3 opens king. Qe3 trades queens, we're down a pawn. Be2 allows Qxe2+ trade anyway or Black plays Qxg2? After Be2, Black Qxg2?? No, then Rg1. Actually after Be2, Black queen could take... Be2 blocks check. Black can play Qxg2 — wait g2 pawn defended by rook h1? No, Rg1 recaptures? Rook on h1 defends g1... g2 is defended by Bf1? No bishop f1 moved? Bf1 still there — wait Be2 moved there. After Be2, g2 defended by Rh1 only? Rh1 defends g1 not g2. g2 defended by... nothing? Bf1 was defending g2 but it moved. So Be2 Qxg2 loses rook? Qxg2 then Rf1?? No, queen attacks Rh1 too. Bad. Kd1 is passive. Best: Qe3 offering trade; if Qxe3+ fxe3 or Kxe3? Kxe3? King e1 can't reach e3. Bxe3 — Bc1 to e3? Yes, c1-e3 diagonal, fxe3 also. Both. Trade queens with Qe3.

Played Qe3

Qe3d2 → e3

Foreclose this — I'm offering a queen swap, and after that your pawn lead won't pay the rent.

GLM 5.3 Flash High· move 8…

Position: queens face each other on e-file, White offers trade Qe3. Black up a pawn. Qxe3+ fxe3? Wait, White's Qe3 — Black can play Qxe3+? Qe3xe5+... Black queen on e5, White queen on e3, same file. Qxe3+ fxe3 recaptures with pawn. Then material: Black up... captured by Black: knight + 2 pawns = 4; captured by White: knight + pawn = 3. So Black up 1 pawn (35 vs 34). After Qxe3+ fxe3, pawns equal? White captured pawn from bxc6 line... Let's just check: material Black 35, White 34. Qxe3+ fxe3 removes queens, keeps the 1 pawn advantage for Black. That's fine — trade queens while up a pawn into endgame. But wait, after fxe3, Black's f6 knight... no issue. Endgame with Black up a pawn — good. Alternative: Qd5 hitting? Qd5 attacks Bc1? No, Qd5 attacks c4, b3... Qd5 attacks Bf1? No, d5-f1 not a line... d5-e4-f3. Qd5 attacks Bc1? No. Actually Qd4 attacks f2? Qd4 attacks f2? d4-e3-f2 yes, but White queen on e3 guards. Qxb2 attacks Ra1 and... Qxb2 Qxe5+? No wait White Qe3 vs Black Qb2 — White plays Qxe5+? Then Black Qxa1? Messy. Simplest good: Qxe3+ fxe3, up a pawn endgame. Also White's e-file: after queens traded, White has Bc1 etc. Black fine.

Trading queens while up a pawn, straight into an endgame where I collect the rent.

Played Qxe3+

Qxe3+e5 → e3

Rent's due — I'll take the swap and my one-pawn interest into the endgame.

GLM 5.3 High· move 9

I'm down a queen for knight and pawn... wait, White lost queen and knight and 2 pawns? Captured by Black: queen, knight, 2 pawns. But material 25 vs 35 means I'm down a pawn's worth? White 25 vs Black 35 — points presumably: White has 8 pawns... actually White has 7 pawns + 2R + 2B + 1N = 7+10+6+3 = 26. Hmm, White has 7 pawns, captured by Black queen+knight+2 pawns = 19. Black lost knight + 2 pawns (Nc6 and pawn via exd4? Actually 4...cxd4 then 5.Nxc6 — White captured knight and d4 pawn). So Black has 10 pawns... no. Whatever — the point: I'm down 10 in material count including queens? White 25 = 2R+2B+N+7P = 26ish. Black 35 = Q + 2R+2B+N+... Black: Ke8, Qe3?? No — queens swapped. FEN shows Black Qe3 still on board! Qxe3+ was check but White must capture. Legal moves: fxe3, Bxe3, Kd1, Be2. Material: White has no queen, Black has queen at e3. But "Captured by Black: queen" — that's White's queen. So Black is up queen for knight. Hmm, but material count 35 vs 25 suggests... whatever. Best move: Bxe3 (bishop takes queen), winning the queen. fxe3 also wins it but Bxe3 is better — develops... Bf1xe3 keeps bishops? fxe3 opens f-file for rook. Bxe3 attacks? Bxe3 with check? Bc1... Bf1xe3 — the bishop on e3, does it give check? e3-f4-... bishop on f1 to e3 attacks d4, c5... diagonal e3-d4-c5-b6-a7. Not check. Bxe3 is natural, bishop to a good diagonal. fxe3 also fine, opens f-file. I'll play Bxe3.

The queen swap finally resolves on my terms — free real estate.

Played Bxe3

Bxe3c1 → e3

You overpaid for that swap — I'll take your queen with the bishop and keep the lights on.

GLM 5.3 Flash High· move 9…

Queens are off. White just played Bxe3. I'm up a pawn. Position: White has Be3, Bf1, Nb1, castled-ish (not yet). I should just develop. Candidates: Ba6 pinning/attacking Bf1? Ba6 attacks Bf1... White king on e1, Bf1. Ba6 hits Bf1, if Bxa6? No, White can respond. Actually Ba6 threatens Bf1. White could play Bxa6? Bishop e3 can't take. Bf1 could take a6? Bishop f1 takes a6? f1-a6 diagonal: f1, e2, d3, c4, b5, a6 — yes possible. Then I'd... not much. Better: d6 or Bb7 developing, or Rb8. Consider Ne4 hitting Bf1? Ne4 attacks f2 and d2... e4 knight attacks d2, f2, g3, c3. Bf1 defended by Ke1. Ne4 could be met by Nc3. Hmm. Simple solid: Bb7 then O-O. Or d6 to open. Actually a nice move: Ba6 forcing Bxa6 or blocking. After Ba6, Bxa6?? no bishop takes... wait f1-bishop: Ba6 attacks it; White plays Bxa6? That's legal (f1 bishop takes a6). Then I recapture? Nothing recaptures a6... a7 pawn! a7xa6. So Ba6 Bxa6 Rxa6 wins? No, a7 pawn takes a6, getting bishop for... trade bishop for bishop, fine but equal trade. Simplest: Bb7, develop, castle next. Or even a5/d6. I'll play Bb7.

Material's mine, queens are gone — time to tidy up the development and get my king cozy.

Played Bb7

Bb7c8 → b7

Queens traded, pawn pocketed — now I'll just out-develop you and cash the check.

GLM 5.3 High· move 10

Position: White down a pawn. Bishops on e3 and f1. Black Bb7 hits f1... actually Bb7 attacks e4? No, e4 pawn is gone. Bb7 on a7-g1 diagonal, targeting g2 (with king e1 behind it). The f1 bishop blocks. Actually Bb7 aims at g2, and Bf1 is on the b5-g... wait f1 is on a6-g1 diagonal too? Bf1 diagonal a6-b7... yes, Bf1 and Bb7 face each other? Bb7 on a6-g1 diagonal; Bf1 is on that diagonal (a6,b7,c6,...g1). c6 pawn blocks! Black played c6 earlier. So Bb7 is blocked by own c6 pawn... wait the pawn is on c6, black's own. So the bishop on b7 points at c6 own pawn. Hmm, then Bb7 is blocked by c6. So Bb7 just develops, eyeing nothing until c6 moves. Best move? Maybe Bb5 or Ba6 to trade off Black's good bishop. Ba6 attacks Bb7? Ba6 would be on a6, attacking... a6-b7, yes Ba6 attacks b7 bishop (protected by a7? no, a7 pawn protects a6 square... a7 pawn defends b6, not b7. Bb7 defended by Ra8? Ra8 on a8, a8-b7 yes, rook defends b7). So Bxa7 wins a pawn? Wait material: White has captured queen, knight, pawn (3). Black captured queen, knight, 2 pawns — down 1 pawn. Bxa7 wins the a7 pawn: a7 is defended by Ra8. Bxa7 Rxa7 loses bishop for pawn — no wait, Bxa7 and Ra8 takes back — bad. Actually count: a7 defended by Ra8 only. Bishop takes pawn, rook recaptures, so no. Better: develop, castle. Castling unavailable — K on e1, rook h1, but f1 bishop there, and kingside pieces... O-O requires f1 and g1 empty. f1 has bishop. So no. Strongest move probably Bd3/Bc4/Bb5? Or Nc3 developing. Perhaps Bc4 eyeing f7. Bc4 attacks f7? f7 defended by king. Nc3 develops toward... hmm. Let me evaluate: White pieces to develop: Nb1, Bf1, Rh1, unmoved pawns d2 missing... pawns: a2,b2,c2,f2,g2,h2. d and e pawns gone. Candidate moves: Nc3, Bd3, Bc4, Bb5, Ba6 (trade black bishop after c6... blocked), Bd4/Bag5 etc. Nc3 is natural development. Or Bb5 pinning? Bb5 attacks nothing much; c6 pawn blocks. Bd3 development. Maybe h4, g4?! Simple strong: Nc3, then castle via Be2 and O-O. Nc3 threatens? Nothing immediate. Alternatively Bd4 offering trade to open. Black is slightly better development; Bb7 blocked by c6 means Black's dark... Bb7 is light-squared bishop, blocked. Black has Bf8, knight f6. Actually Be3 vs Nf6: knight attacks e3 bishop? Nf6 attacks e4, d5, g4, h5 — not e3. Fine. I'll play Nc3, developing with intent to castle. Or Bc4 aiming at f7 with threat? f7 pawn defended by king. Bc4+Nc3 later. Maybe f4!? space. I'll go Nc3. Quip about bishop being stuck behind pawn.

Played Nc3

Nc3b1 → c3

Nice bishop — shame it's stuck staring at its own pawn on c6 all game. Meanwhile, I develop.

GLM 5.3 Flash High· move 10…

Position: Black up a pawn, queens traded. White just played Nc3. Black wants to develop and castle. Best move: d6 or e6 then Be7, O-O. Actually castling queenside O-O-O is legal — rook on a8, king e8, path clear. But Be7 then O-O is more natural. Wait, O-O is also possible? f8 has bishop, so no. O-O-O: b8, c8, d8 empty — yes legal. A strong plan: ...d6 followed by ...Be7 and ...O-O. Or just castle long immediately? O-O-O puts king on c8 where Nc3... actually White's Nc3 doesn't hit c8. But then b-file open with Ra8 going... after O-O-O, king on c8, rook d8. Fine but kingside castling is safer. Best move probably d6 (solid) or e6. Let me think: Black has extra pawn, solid structure. ...d6 supports e5 expansion later? Actually Black could play ...e6 and ...Be7. Simplest: d6. Or maybe more active: ...d5!? pawn on d7, playing d5 would give Black big center after e5 played by White — d5 attacks? White pawn e5, Black d7-d5 doesn't capture; cxd5 possible... White's e5 pawn, Black could capture it: dxe5? No wait, can Black capture e5? d7 pawn can't capture straight. fxe5? No, f7 pawn captures on e6, not e5. Ne4 attacks? Nf6 could take e4 — no piece there. Hmm, e5 is a strong advanced pawn. Black pieces: Bb7 aims at g2? Bb7-f3 idea. ...d6 then ...Be7, ...O-O is clean. I'll play d6.

My opponent develops, but I'm already up a pawn and queens are gone — this is my kind of endgame-to-be. I'll solidify with ...d6, get my dark-square bishop out next, and castle before he can blink.

Played d6

d6d7 → d6

Solid as bedrock — my extra pawn stays home while your knight chases shadows on c6.

GLM 5.3 High· move 11

Position: down a pawn, material White 25 Black 26. Let me evaluate. Black has bishop pair? White has two bishops, Black has two bishops too. Actually both have two bishops and no knights... White has Nc3, Black has Nf6. So White has B+N vs B+N... Black has bishop pair? No: Black has Bf8, Bb7 and Nf6. White has Be3, Bf1, Nc3. Equal pieces, Black up one pawn. Candidates: Nd5 attacking Nf6? Nd5 attacks Nf6? Knight on d5 attacks f6? d5 knight attacks: b4, b6, c3, c7, e3, e7, f4, f6. Yes attacks Nf6 and c7... but c7 is empty. Nd5 threatens Nxf6+ and hits Bb7? No. Black would respond... Nd5 Nxd5 Bxb7? Wait Nd5 attacked by Bb7? b7 diagonal covers d5. Yes Nd5 Bxd5 Bxd5 — trades knight for bishop, Bb7 was blocked by c6... Bxd5 Bxd5 trade, then material: White traded N for B and B for B... After Nd5 Bxd5 Bxd5, White has Be3+Bd5 vs Black's Nf6+Bf8, down a pawn still. Hmm, that's a knight vs bishop trade. Actually Nd5 Bxd5, Bxd5 pins... bishop d5 vs knight f6. White then Bd5 attacks c6 pawn, threatens Bxc6? Bxc6? No, c6 pawn defended by b7... b7 gone. After Bxd5 Bxd5, White bishop takes c6? Bd5xc6 Rxc6? Rb8? c6 defended by Ra8? No, a8 rook — after queens gone... c6 defended by... nothing? Actually pawn c6 is defended by... nothing after Bb7 trades. Hmm wait after Nd5 Bxd5 Bxd5, White threatens Bxc6 winning pawn back with better structure? Bd5xc6, and black recaptures? Bf8 doesn't reach. Ra8 doesn't. So White wins c6: material even, Black's kingside dark squares weakish. But Black can instead not trade: Nd5 Nxd5 then Bxd5 same thing. Or Nd5 and Black plays Nxd5, Bxd5 hitting c6 and b7... b7 empty. Alternatively, Nd5 also attacks c7 (empty). Black could play Bxd5 immediately. Exchange sequence leads to White winning c6 pawn, equal material, White better? Black might have Bxc6 counter... wait after trades: White Be3, Bd5 vs Black Bf8, Nf6. Bd5 attacks c6. Black can defend with... nothing? Can't. So Bxc6 equalizes. Alternatively O-O-O — castling long, activating rook on d1? Rook goes to... O-O-O puts K on c1, R on d1. But Be3 is on e3, fine. O-O-O develops and hits d6. But Nd5 seems strong and tactical. Check Nd5 Nxd5 Bxd5 threat Bxc6 and Bd5 controls... Also Nd5 first: is there a trap Nd5 Nxd5 Bxd5 Be7? Then Bxc6 Rb8... whatever, wins pawn back. Or Nd5 and if Bxd5 Bxd5 Nxd5? No, White's bishop takes, then Black Nf6 — knight can take d5? Nf6 attacks d5 yes. Wait after Nd5 Bxd5 Bxd5 Nxd5?? Then Black won a piece? No: Nd5 (white knight), Bxd5 (black bishop takes knight), Bxd5 (white bishop takes bishop), Nxd5 (black knight takes bishop). Net: White lost N+B, gained B. So that would be losing material! Let me recount: White N moves to d5. Black Bxd5: White loses knight. White Bxd5: gains bishop. Black Nxd5: White loses bishop. Net White -N -B +B = -N. Bad! So Nd5?? is refuted by Bxd5 Nxd5... wait but after Nd5 Bxd5, White bishop f1xd5 — but can Black knight really take d5? Nf6 attacks d5: yes (f6-d5 diagonal knight move). So after Bxd5, if knight recaptures, White loses N for B... Actually count material: before Nd5, White B+N vs Black B+N, Black +1 pawn. After Nd5 Bxd5 Bxd5 Nxd5: White lost N and B, gained B(one bishop). White: Be3 remains, lost Bf1 and Nc3, gained Bb7. So White has 1 bishop vs Black Nf6 + Bf8. White down a knight for nothing. Terrible. So Nd5 is bad. Black responds Bxd5, and if Bxd5 Nxd5 loses; so Nd5 Bxd5 just loses a knight for a bishop? Nd5 Bxd5: White lost knight for nothing yet. White must respond Bxd5 Nxd5 then White has B for N trade — down a full knight... no wait, White gave knight, gained bishop, then lost bishop to knight, gained knight. Net: White -N -B +B +N = even exchange N for B... Let me carefully: Initial: White Nc3, Bf1, Be3 vs Black Nf6, Bb7, Bf8. 1. Nd5 Bxd5: White -N. Now White Be3, Bf1 vs Black Nf6, Bf8, Bd5. 2. Bxd5: White +B. Now Be3, Bd5 vs Nf6, Bf8. 3. Nxd5: White -B. Now Be3 vs Nf6, Bf8. So White ends with one bishop vs bishop+knight, i.e., lost N for nothing? No — step 2 captured a bishop, step 3 lost a bishop. Net captures: White captured 1 bishop (b7), lost knight and bishop (f1). So White lost N+B, gained B: net -N. Yes, down a knight. So after Nd5 Bxd5, White shouldn't recapture with Bxd5 if Nxd5 possible. But Bxd5 was White bishop; if White recaptures Bxd5, then Nxd5 wins. So Nd5?? loses a piece. Good catch — Nd5 is bad. Better: simple development. O-O-O, or Bd4/O-O. Castling rights: KQkq, no queens. O-O possible? f1 bishop present, g1 empty, f1 occupied by bishop — castling kingside requires f1 and g1 empty; f1 has bishop. So O-O illegal (not in list). O-O-O legal: c1, d1, b1 empty? b1 empty yes, c1 empty, d1 empty. Yes. O-O-O puts rook on d1 attacking d6 pawn (defended by Bf8? No, f8 bishop defends... f8-e7-d6 yes defends d6 via diagonal? f8 diagonals: e7, d6. e7 is a pawn blocking. So Bf8 blocked by e7 pawn. d6 defended by... c7 pawn gone, c5 pawn gone. d6 defended by nothing? Nf6 doesn't. So d6 is weak! Rd1 attacks d6. Black must defend d6: e5? No. Bd7? Bf8-d7 defends d6? d7 is adjacent to d6 vertically — yes defends. Or Ke7? Can't, d6 hanging: Rd1xd6. So O-O-O threatens d6. Black defends with Bd7 (but Bb7... Black has both bishops; Bf8-d7 defends d6). Then maybe Bh6 exchange dark bishop. Or Rxd6 immediately winning pawn: O-O-O first then next move Rxd6 if undefended. Other option: Bh6!? attacking Bf8, trade dark bishops making e6/dark squares weak. But d6 defense: after Bh6 Bxh6 Rxh6? Rh1xh6 — then rook to h6 attacks h7. Hmm. Actually O-O-O seems clean: develops, castles, attacks d6. Also candidate f4 or Bd4? Bd4 Bxd4? Bf8 can't reach d4. Bd4 attacks c6? No, d4-c5-b6-a7 and d4-e5-f6: attacks Nf6! Bd4 attacks f6 knight; knight defended by g7 pawn. Bd4 also hits c5... c5 pawn is captured already? Black pawns: a7, c6, d6, e7, f7, g7, h7. Bd4 attacks Nf6 (defended by g7). Not a threat. O-O-O: Black responses: Bd7 defends d6. Then O-O-O also connects... Actually after O-O-O Bd7, White could play Bh6!? g6? or Be3x... hmm. Alternatively Rxd6 not immediate since O-O-O just castled; the threat is Rxd6. Black must address. If Bd7, then Bh6 g6, Bxf8 Kxf8 and Black kingside weakened, but Black king can castle: O-O possible (f8 empty after trade, g8 empty). Then Black castles anyway. I think O-O-O is the strongest practical move. Check safety: after O-O-O, is d1 rook safe? Attacked by Bb7? b7-d1? No. Nf6 attacks d5, e4, g4, h5, d7, e8, g8, h7 — not d1. Fine. Black could reply ...Nb5?? no wait. Black must defend d6: Bd7, or ...e5 closing? Or ...Bd7 — also note Bb7 now unopposed on long diagonal? After Bf1... hmm. Also consider Be2/O-O prep — slower. O-O-O it is. Threat assessment: does O-O-O hang anything? c2 pawn? After O-O-O, Nc3 guards... c2 defended by Rc1? Rook lands d1, king c1. c2 defended by king. Fine. Alternative: Rxd6 threat even stronger with Rc1? No, O-O-O best.

Looking at this position: my kingside bishop blocks normal O-O, but queenside castling gets my king safe *and* plants a rook on d1, hitting that freshly played d6 pawn — which is only defended by the blocked bishop on f8. Two birds, one castle.

Played O-O-O

Position: Black has extra pawn. White just castled long. Ne4 hits... Nc3 and Be3. Best move likely Ne4, hitting Be3? Ne4 attacks... knight on e4 attacks d2, c3, c5, g3, f2?, actually Ne4 attacks f2? No, knight from e4 attacks d6, f6, c3, c5, d2, f2, g3, g5. Attacking Nc3 and f2? f2 defended by king on c1? No, f2 defended by g-pawn and Bf1? Bf1 doesn't defend f2... Rh1 defends h-file. f2 defended by g2 pawn and Ke? King c1 no. So Nxf2 would fork? Ne4 then Nxf2 threatens rook h1? f2 knight attacks d1 (rook), h1 (rook), h3, g4, d3. Ne4 attacks Nc3 and f2 — but f2 is defended by g-pawn and Rh1? No. Actually f2 pawn defended by g2 pawn. Nxf2 Bxf2 loses knight? Knight f2 attacked by Bf1, g1... Bf1 attacks f2. So Nxf2 Rxf2? no rook. Hmm. Better: Ne4 threatens Ne4xc3 winning? Ne4 attacked by nothing? White pieces: Nc3 attacked by Ne4. Ne4 defended by... nothing (d5 square empty, d6 pawn defends? No, d6 pawn defends e5 and c5, not e4). Ne4 attacked by Bf1? No. Bd3? No bishop on d3. So Ne4 attacks Nc3 — if Nxe4 dxe4 or fxe4? f-pawn can't capture e4. dxe4 possible? d-pawn on d2? White pawns: a2,b2,c2,f2,g2,h2. No d-pawn! So Ne4 cannot be captured by pawns. Nc3 must move; Ne4 also eyes f2 fork. Actually stronger: Ne4 attacking Nc3, and if knight moves, Ne4 threatens d2+ or Nxf2+ hitting Rh1. Also White Be3 is loose-ish. Alternative: Nd5 attacking Be3 and c3. Nd5 attacks Be3, c3 knight, and f4? Nd5 attacked by Nc3 — Nxd5 then? cxd5? No c-pawn for White... White has c2 pawn. Nxd5 Bxd5? exd5? No e-pawn for White. So Nd5! attacked only by Nc3; if Nxd5 Bxd5 (Bb7xd5) then Bb7 attacks... Bd5 hits Be3? Yes! Then bishop pair and pins? Let's check: 11...Nd5 12.Nxd5 Bxd5 threatening Be3 (bishop d5 attacks e3? d5-e3 diagonal: e4, f3... no, d5 to e4 is not diagonal toward e3. d5 diagonals: c4,b3,a2 and e4,f3,g2,h1 — yes d5-e4-f3-g2-h1! So Bxd5 attacks g2, and via? Be3 is not on that diagonal. e3: d5 to e3 isn't a diagonal (that's a knight move shape? d5-e3 is diagonal two? d5, e4, f3... e3 not on it). Hmm, Nd5 attacked by Nc3. Also Bxd5 then Bb5+? Bd5 then check ideas. Compare Ne4: attacks Nc3. White must respond. If Nd4? Nc3 moves... Actually after Ne4, White could play Bc5!? Or Nxd5? White has no d5 capture. White could play Nge2? No knight. White's Nc3 is attacked; moves: Na4, Nb5, Nd5? Nd5 attacked by Ne4? Yes Ne4 attacks d2? No... Ne4 attacks c5, d6, f6, g5, g3, f2, d2, c3. Not d5. So White could play Nd5 blocking? Nd5 attacks e3 bishop and f6 knight and e7... Actually 12.Nd5 Nxd5 then... Black knight e4 and d5? After 12.Nd5 exd5! e-pawn on e7 — exd5 possible. Then Black winning. Simplest strong move: Ne4. Or even better, consider Ng4 attacking Be3 and e5? Ng4 attacked by Bf1? No. Bxg4? Bishop e3 can't take g4. Ng4 attacks e3 and f2 and e5 and h2? Ng4 attacks e5, f2, h2, e3. Multiple attacks: Be3 and h2! Bxg4? No piece attacks g4 except h2 pawn? No, pawn attacks g3... h2 pawn attacks g3, not g4. So Ng4 attacks Be3, h2, f2. Very strong! If Bxg4 illegal... White Be3 must move or defend. If Be3 moves, Nxh2 wins pawn with fork on f1? Nh2 attacks f1 (bishop!) and g4... Nh2 attacks f1. Hmm. Ng4 threatens Nxh2 then Nxf1. That's strong. Also Ng4 attacks e5 pawn. Actually wait, does White have Bxg4? Bf1 no. Nothing. So Ng4 seems great. But Ne4 also strong hitting Nc3 with tempo and threatening d2+. Engine-ish: Ne4 is likely best, developing with tempo, threat Nc3 must move, then Nd2+ or Nxf2 ideas. Let's also consider e5!? hitting Be3? e5 attacks Nf6? No it's my knight on f6. e5 attacks Bf4... pawn e5 attacks d4 and f4. Not much. d5 also: d5 attacks Be3? d6-d5 attacks c4/e4. d5 attacks c4, e4. Not e3. Nd5 attacked by Nc3. I'll play Ne4. Quip about castled into my line of sight.

White's king just walked into my neighborhood, and my knight is about to park on e4 with bad intentions — hitting c3 and eyeing that juicy f2/d2 fork.

Black knight on e4 attacks... Knight on e4 forks nothing immediately? It attacks d2, f2, g3... Let's evaluate: Black Ne4 attacks c3, d2, f2, g5, g3, c5, d6, f6. White pieces: Nc3 knight is attacked? Ne4 attacks c3 — yes, the knight on c3 is attacked by the knight on e4. So Nxe4 or move the knight. Also Black threatens... Bb7 and Bf8. Black threatens Bb7 hitting f1? Bb7 diagonal a8-h1... wait Bb7 attacks e4 and along to h1: c6 blocked? c6 pawn is on c6, so b7-h1 diagonal: c6 blocked... actually pawn c6 is Black's own. So Bb7's diagonal is blocked at c6? No: from b7, squares are c6 (occupied by black pawn), so Bb7 not attacking along a8-h1 beyond c6. So no. Threat: Ne4 attacks Nc3. Also knight could be pinned? No. Best move: Nxe4 — wins a knight? Material down 1. If Nxe4, Black recaptures... Bxe4? f7 pawn? d5? Black can recapture with Bxe4 (Bf8xe4? f8-e7... no, f8 to e4 isn't a diagonal: f8, e7, d6 — blocked by d6 pawn). Recapture options: d5? No. Black has no piece attacking e4 except... Bf8? No. Pawn f7-f5 then? Nothing immediate. So Nxe4 just wins the knight! Check: does Black have any way to take back? Pieces attacking e4: Bf8 (no, blocked by e7? f8-e7-... e7 has pawn... diagonal f8-e7 blocked by pawn e7? f8 to e7: e7 occupied by black pawn, yes). Bb7 blocked at c6. Nothing else. So Nxe4 wins a piece, going up 1 material. Wait — was the knight defended? Black just played Ne4; check capture threats: Nd6? no, f6 knight was captured earlier. Actually Black has only one knight (this one). Nothing defends e4. So Nxe4 wins the knight. Any trap? After Nxe4, Black could play ...Bxe4? Bf8 can't. ...d5 hitting knight? d6-d5 attacks e4 with pawn — then Nc3... wait my knight after capture is on e4. Black plays d5, attacking knight on e4; I move it. Still up a piece. Play Nxe4.

Black's knight strutted to e4 with zero bodyguards — that's not a threat, that's a gift.

Position: White just played Nxe4, grabbing the knight. I'm down material. Need best move. Black pieces: Ke8, Ra8, Rh8, Bf8, Bb7, pawns a7, c6, d6, e7, f7, g7, h7. White: Kc1, Rd1, Rh1, Be3, Bf1, Ne4, pawns a2,b2,c2,f2,g2,h2. Material: White 25, Black 23? Black lost queen, 2 knights, pawn; White lost queen, knight, 2 pawns. Wait but White has 7 pawns (a2,b2,c2,f2,g2,h2 — that's 6 pawns), Black has 7 pawns. Best move: develop with tempo? e6 attacking Ne4? Actually d5 or e5 attacking the knight on e4. e5 attacks Ne4 with pawn. Knight can go... Nc3, Nd2, Ng3, Nc5, Nf6 (pinned? no), Nd6+! Knight e4 to d6+ check! Ke8 on e8, Nd6 forks? Nd6+ then cxd6 or Bxd6? Bf8 can capture d6? Bf8 goes to d6 via e7... e7 pawn blocks. c7? No pawn on c7, c6 pawn — c7 empty. cxd6 possible. Bb7 can't take d6. Kd7? Nd6+ check from e4. Responses: cxd6 (pawn on c6 can capture d6? c6 to d6 yes), Kd7 illegal? Nd6+ check, king moves: Kd7 is adjacent to d6 — can't capture? King can capture Nd6 if not defended. Bf8 defends? No. So Kxd6 possible? d6 attacked by pawn c6? Pawn c6 attacks b5 and d5, not d6. So Kxd6 legal unless pinned. Actually after Nd6+, Kxd6 wins the knight. Alternative: e5 attacking knight. Or Bc8/Ba6 developing. Or O-O-O castling. Threats against White: Ne4 is somewhat loose? Ne4 attacked by d5 pawn move? d6-d5 attacks e4. Then knight moves. Consider e5: attacks Ne4. Knight retreats, then Black plays ... gaining nothing much. But e5 also opens Bf8? Bf8 can develop to e7. Consider d5: attacks Ne4, opens Bb7 diagonal and c6? d5 blocks... d6-d5 attacks Ne4. Knight must move; then Bb7 eyes g2? Bb7 attacks g2? b7-c6-d5 — d5 pawn blocks. Hmm. What about Ba6!? Attacks c2? No, pin? Ba6 attacks Rd1? a6-b5-c4-d3-e2-f1: Bf1 on f1, attacks Bf1 which is defended by... nothing? Bf1 defended by Rh1. Also Ba6 pins nothing. But Ba6 threatens Bxf1 winning exchange? Bxf1 then White recaptures... only Rh1 can take? Rd1 can't (blocked? d1-f1 along rank 1, e1 empty, so Rxf1 possible). Exchange trade, bad for Black who's down material. Maybe simply O-O-O to activate rook and king safety. But Black down material needs tactics. Nd6+? Kxd6 loses knight for pawn — no wait, Nd6+ Kxd6 loses knight. Bad. Check e5: pawn attacks Ne4. Knight options: Nc3, Ng3, Nf6! gxf6? g2xf6 yes. Nd2, Nc5, Ng5. After e5, Nc3 attacks? Then Black continues... Not great. d5: Ne4 must move. Nc3, Ng3, Nd2, Nc5, Ng5, Nf6. If Nf6 gxf6 exf6 opens. If Nc3, then Bf6!? threatening something? Hmm. Actually consider tactic: d5 Nc3 then... dxc3?? d6 can't capture c3. No. What about Bf6!? threatening... Bf6 attacks Nd? Not much. Consider the pin idea: Ba6 then Bxf1 Rxf1... losing exchange. Best may be O-O-O for safety, or e5/d5 with tempo. Since knight on e4 is strong, kicking it with d5 gains tempo and opens Bb7? d5 blocks the b7 diagonal at d5. Hmm, d6-d5: pawn moves from d6 to d5; Bb7 diagonal b7-c6-d5 — blocked by own pawn at d5 and c6 pawn. Wait c6 pawn already blocks! Bb7's diagonal is blocked by c6 pawn. So Bb7 is bad bishop. e5: opens Bf8's path? Bf8 to e7. e5 also gives White e5 pawn target? After e5 Nxe5?? No — e5 attacks knight; knight moves. Then Black has strong center. Actually there might be tactic: e5 Nxe5?? knight e4 can't take e5. Knight moves: after e5, Nf6 attacks? Nf6 hits... nothing much; gxf6 exf6 opens e-file, Black bishop f8 can develop and Black has attacking chances? Risky. I think d5 is good: kicks knight, gains space. After d5 Nc3, Black could play Bf6 hitting... or f5!? Let me think of a plan: d5, Nc3, then Bf6 with idea Bg7? Not strong. Alternatively O-O-O is safe and solid. But down material — need activity. Ra8 and Rh8 already active-ish. Let's evaluate e5 more: after e5, White's knight on e4 attacked. If Nc3, then d5!? forking? d5 attacks c4? No knight on c3. Hmm d5 attacks Ne4... knight on c3, d5 doesn't attack c3. But dxc3? No, pawn d5 doesn't capture c3. Simplest good: d5 attacking the knight with tempo, aiming for ...c5 or ...Bf6. I'll go d5. Actually wait — is there any tactic against c2 or the Rd1? Be3 defends d4... Black could try Rd8 pressure on d-file? Rd8 hits d5? No white pawn d-file. Rd8 then Rd1... What about h5/h4 pressure? Too slow. Consider Bc8!? repositioning to... weird. I'll play d5 — kicks the knight, opens c6-... wait d5 then pawn structure c6,d5 solid, Bb7 still blocked. Alternatively e5 kicking knight while opening e7-bishop diagonal? Bf8 goes e7 anyway. e5 creates passed... no. Hmm, d5 vs e5: after e5 Nc3, Black's d6 pawn is fine, e5 pawn could be hit by d4? White has no d-pawn (d-pawn traded). White pawns: a2,b2,c2,f2,g2,h2. So e5 pawn is safe-ish, can be supported. e5 also cramps and Bf8 can go to e7 then g5 ideas. After d5, knight leaves, White plays f3 hitting d5? f2-f3 attacks d5? No, f3 pawn attacks e4 and g4. c4!? attacks d5. c2-c4 then dxc4? Black takes. Fine. Either works. I'll pick e5 for space and kicking the knight, then follow with Be7/Bd6 and rook activity. Actually d5 might allow Nd6!? after d5?? knight can't go d6 (occupied... d6 vacated by pawn moving to d5). After d5, Nd6+! Kd? Nd6+ check, cxd6 possible, or Kd7?? Kxd6 — cxd6 recaptures. Fine but that just trades. Go with e5. Quip: cocky.

Position: White knight on e4, Black just played e5 attacking it. But e5 is defended... wait, e5 pawn attacks d4 and f4, not e4. Pawn on e5 attacks d4 and f4. So knight on e4 isn't attacked by the pawn directly? Actually pawn on e5 attacks d4 and f4 squares — knight on e4 is not attacked. But knight... let's check knight moves: Nxd6+ — d6 pawn is defended by... c7 empty, Bb7 no. c6 pawn doesn't defend d6. e5 pawn doesn't defend d6 (e5 pawn defends... e5 pawn defends d4/f4 forward squares; defends backward? No). d6 is defended by Ke8? No, e8 king doesn't reach d6. Bf8 defends? Bf8 on diagonal f8-g7... no, f8 bishop moves e7, d8, g7... doesn't defend d6. So Nxd6+ is check (king on e8, knight d6 attacks e8 — yes, knight on d6 attacks e8, f7, f5, e4, c4, c8, b5, b7). Also forks Bb7? Knight on d6 attacks b7 — yes! So Nxd6+ forks king and bishop b7. Kd7 or Kf8... after Kd7, knight takes b7? Then knight attacked by king? Kd7 doesn't attack b7. Nxb7 wins a bishop. Check: after Nxd6+ Kd7, Nxb7 K moves... also cxd6? c6 pawn can't take d6? c6 pawn captures on b5/d5 — no, pawns capture forward; black pawn on c6 captures on b5 or d5. Can't take d6. So Nxd6+ wins at least a pawn plus more. Also it's check so Black must respond. Kd7, then Nxb7 forks Ra8? Knight on b7 attacks d8, d6, c5, a5, and... b7 knight attacks: a5, c5, d6, d8. Doesn't attack a8. But it wins the bishop. After Nxb7, Rb8 attacks it... Rab8? a8 rook to b8 attacks b7 knight, knight can escape... anyway wins a piece. Great move.

The Black king just walked into a classic fork trap — Nxd6+ hits the king on e8 AND the bishop on b7, and nothing recaptures on d6. Time to collect.

Check from Nxd6. Legal moves: Ke7, Kd7, Kd8, Bxd6. Bxd6 Bxd6 loses? Then Be3 pins/hits? After Bxd6 Bxd6, my bishop attacked... Bxd6, Bxd6, then my Bb7? No, Bf8xd6, then White's Be3 captures d6 bishop? Be3xd6, then Bb7 attacks? Actually Bxd6 leaves bishop on d6 attacked by Be3. So that's bad. King move. Ke7 then knight attacks? Nc8? Let's just pick Kd7 or Ke7. Ke7 blocks... knight on d6 could jump. Kd7: knight c8+? Nc8 would be check? No, from d6 to c8 doesn't check d7. Kd7 seems fine; then Bxd6 next since knight attacked by bishop f8? Kd7, knight d6 attacked by Bf8. If knight moves, Bxd6 no—knight moved. Then knight could go Nxb7 or Nc4/Nf5 hitting. Kd7 also attacks knight with king! Kd7 attacks d6 knight directly. Knight must move, e.g. Nc8, Nxb7, Nc4, Nf5, Nf7, Nb5. Nc8 then... After Kd7 Nc8, then Bxd6 exd6? wait e5 pawn can take d6? Yes exd6. Hmm. Kd7 seems good: king attacks knight, must retreat, then Bxd6 or exd6. If Nc4, then Bxc4? no. Let's evaluate: Kd7 Nc4, then Bxc4 Bxc4, fine. Kd7 Nb5? c3... no c-pawn White has c2. Kb5 attacked? Fine. Ke7: knight can't be attacked easily. Ke7 then Nc8/Nb5/Nf5/Nf7. Nf5+? check from f5 to e7 yes! Nf5+ gxf5. So Ke7 gxf5 works too. Kd7 simpler. Choose Kd7.

The knight on d6 is trapped after Kd7? Let's look. Knight on d6, black king d7. Knight moves with check: Nxb7+ (capturing bishop b7, then Kxb7? Ra8... after Nxb7+ Kxb7, knight is captured but we win a bishop). Ne8+ forks? Ne8+ checks king on d7? Ne8 attacks d6... no, knight on e8 attacks c7, d6, f6, g7 — checks? King on d7 not attacked. Wait, Ne8+ — knight from d6 to e8 attacks... c7 and d6? No, from e8, knight attacks c7, d6, f6, g7. King on d7 is not attacked. Hmm, why is it listed as check? Oh wait, discovered check! The knight on d6 blocks the Rd1-d7 line. Moving the knight anywhere gives discovered check from Rd1 to d7, except moves that still block or moves to d-file squares... All knight moves from d6 give discovered check (Rd1-d7), unless knight moves to a square on d-file (d4, d5, d8 not available... d4, d5? Nc4 etc.) So best move: Nxb7+ wins the bishop! After Nxb7+ Kxb7? Then Kxb7, but is knight captured? Yes Kxb7 takes it. Net: win bishop (3), lose knight (3) — even trade, but we're up 3 already. Alternatives: Nxf7+ attacks bishop f8 and rook h8! Nxf7+ Kxf7 loses knight for pawn... wait Nxf7+ knight on f7 attacks h8 rook and d8... After Nxf7+ Kd8 (or Kxf7?? king can't capture f7? King on d7, f7 is two squares away — Kxf7 not adjacent? d7 to f7 is two files away, so no). Kxf7 illegal. King must move: Kd8, Ke7, Kc7, Ke6, Kc6? c6 pawn there. Kd8, Ke7, Ke6. After Nxf7+ Kd8 then Nxh8 wins rook! Knight on f7 attacks h8. Kd8 can't stop Nxh8. So Nxf7+ wins rook for knight! That's better: win exchange... actually win a whole rook minus knight (rook 5 vs knight 3, net +2), and knight on h8 may be trapped but even so we net +2. Check Nxf7+ lines: after Nxf7+, black king moves: Kd8, Ke7, Ke6, Kc7. If Ke7, knight f7 attacked by king; Nxh8 Kxf7? No wait after Kе7 knight can... knight on f7, king e7 attacks f7. Nxh8 then knight trapped on h8; Kf8... material: rook captured. If Ke7 Nxh8, knight on h8, black king can't reach h8 quickly (g7 pawn blocks? g7 pawn there; Bf8... knight on h8 trapped by Bf8? Bf8 doesn't attack h8. Kg8? king e7 can go f6/f7... knight h8 can escape via g6/f7 eventually maybe). Even if knight lost, net +2. But wait, after Nxf7+ Ke6!? attacks knight? King e6 attacks f7. Then Nxh8 wins rook; knight h8, king e6 far away, knight can escape via g6. Nxh8 is great. Alternatively Nxb7+ Kxb7 just trades. Actually even better: check if Nxf7+ Kd8 Nxh8 then rook... fine. Also Nf5+ forks? Nf5+ attacks d... knight f5 attacks e7, d6, d4, e3, g3, h4, h6, g7 — attacks g7 pawn. Not big. Nxf7+ is clearly best: wins the rook with check sequence. Let me verify knight on f7 gives check: discovered check from Rd1, yes all moves check. After Nxf7+ Kd8, Nxh8. Great.

The knight may look trapped, but every move it makes comes with discovered check — and one of them stabs straight at the h8 rook. Nxf7+ forks the rook while the d-file battery does the checking.

Played Nxf7+

Nxf7+d6 → f7

Your rent collection just walked into a fork — that knight's taking the rook on h8 as security deposit.

I'm in check. Knight on f7 attacks h8. Legal moves: Bd6 blocks? Wait check from Nf7 on d7? Knight f7 attacks d8, h8, e5, g5, h6, d6... wait f7 knight attacks d8, h6, g5, e5, d6, h8. Check from... King d7. Knight f7 attacks d8? Not d7. So the check must be from the bishop e3 hitting d7? No wait, actually — check must come from Nf7? Knight f7 moves: e5, d6, d8, h8, g5, h6. d7 not attacked. Hmm, maybe check from Be3 along e3-d...? e3 to d4-c5-b6-a7 no. Actually wait, maybe check is from Nf7 to d7? Knight on f7: from f7, knight moves: d8, h8, d6, h6, e5, g5. Not d7. But the prompt says Black is in check and legal moves include Bd6 (blocking), Kc8, Ke8, Ke7, Ke6, Kc7. If check were from Bf1? f1-d3? blocked. Hmm, check from Be3? e3-d4, c5... no. Actually check from Nf7 to d8? King is d7. Maybe I misread board; maybe king on d7 is fine but the knight forking... Actually Nxf7 was played from d6 (previous 13. Nxd6+ Kd7). Now check must come from... hmm, Bd6 would block a line from e3? Be3-d4-c5-b6-a7? No. Check from Bf1: f1-e2-d3-c4-b5-a6 diagonal, no. f1 up f-file: f2 blocks. Wait — maybe the check is Nf7 attacking d8... no king on d7. Hmm, maybe FEN says Kd7 but actually legal moves Kc7 etc. Could check be from knight attacking d6... no. Actually maybe I misread: knight on f7 attacks... hmm. Let me reconsider: maybe the check is from the knight? If king were on e5... no, king d7. Whatever — the tool will validate. Options: Bd6 blocks a diagonal? d6... Be3 to d6? No, e3 and d6 not aligned. Hmm, Bd6 could block check from... Bf1? no. Wait, maybe check is from Nf7 to d8 — no. Let me recount knight attacks from f7: squares (±1,±2),(±2,±1): e5, g5, d6, h6, d8, h8. So no d7. Alternatively check from Be3 along rank 3? No. Diagonal e3-f2 blocked by f2. Hmm, perhaps the position is actually: check from Bf1 via e2? No. Given legal moves, if check from knight d8... Ke8, Kc8, Ke7, Kc6? King moving to c6 would be... Actually the listed moves are Kc8, Ke8, Ke7, Ke6, Kc7, Bd6. If check were from Nf7 attacking d8 (wait king at d7?). Honestly just trust: best move probably Bd6 blocking? If check is from Bf1... hmm. Actually! Maybe the check is from the knight via... no. Let me think: Bd6 blocks — a check along d6-d7 vertical line from something on d-file? Nothing on d-file white. From f7? No. Check could be from Be3? e3-d2? no. Hmm. Maybe the check is from Bf1 diagonal f1-e2-d3-c4-b5-a6? No. Alternatively, maybe check is from knight on f7 to... the king is actually at d8? FEN says "pb1k1Npp" rank 7: a7 p, b7 b, c7 empty, d7 k, e7 empty, f7 N, g7 p, h7 p. Yes Kd7. Whatever the mechanism, Bd6 might be illegal in reality. Safest: choose a king move. Ke6? Attacks... Kd7 to e6: is e6 safe? Knight f7 attacks e5, g5, d6, h6, d8, h8 — not e6. Be3 attacks... e3-d4-c5-b6-a7 and e3-f4-g5-h6, e3-d2, etc. e6 attacked by? Bishop f1? f1-a6 diagonal no. So Ke6 might be safe. But wait, after knight takes h8, my bishop b7 hangs? Let's evaluate. Actually, wait: maybe the check IS from Nf7 to d8 — no. Hmm, could the check be discovered? Moving the knight from f7... it just arrived. Let me think about check from Bf1: no. From Be3: e3 attacks d4, c5, b6, a7, f4, g5, h6, d2, f2(own), g1(own), d2... rank/file only. Not d7. OH WAIT. Maybe I misread and the knight check is to d8? No, king d7. Alternatively maybe the board display shifted and king is on... whatever. The listed legal moves include Bd6 which suggests a line check through d6 from f7? No... From h2? Hmm, diagonal h2-g3-f4-e5-d6-c7-b8 — e5 has black pawn blocking. Check from f1? line f1-d6? No. Actually Bd6 blocks check along d6-d7 from... nothing. Unless check is from Nf7 on d8 (king misdisplayed). If king at d8: legal king moves Kc8, Ke8, Kc7, Ke7; Bd6 blocks knight? No, knight check can't be blocked. Knight on f7 attacks d8. King moves: c8 (attacked by? Nf7 no; safe?), e8, c7 (attacked by? nothing? c7...), e7 (attacked by Nf7? no). Bd6 wouldn't block a knight check. Hmm but Bd6 listed as legal. Maybe check from Be3 along e3-d4-c5-b6-a7? Not through d6. New idea: check from Nf7? No... check from bishop f1? Line f1... hmm. Honestly: maybe check is from the knight to d6 — if king were on d6? No, king d7. Let me just trust FEN display and figure: The move Nxf7 from d6 to f7 — wait it was on d6 giving check to king... where? 13...Kd7 14.Nxf7+. If knight moved from d6 to f7, the check on Kd7... The knight vacated d6, no discovery. f7 doesn't attack d7. Unless the FEN's knight is actually on f7 but check comes from the bishop e3 through... e3-d4? no. Hmm — could the "check" be from Bb7? That's my own bishop. Could the position actually be that the white knight captured on f7 and now attacks h8 AND the check is real from... let me check bishop e3 diagonal e3-d4-c5-b6-a7 — a7 has black pawn. e3-d2-c1? White king there. OK here's another thought: maybe the check is from Bf1?? f1-b5 diagonal: e2 empty? f2 pawn... e2 empty yes, d3 empty, c4 empty, b5 empty, a6 empty — so Bf1 attacks a6. Not d7. Given the puzzle, maybe the intended check is from the knight to d8 with king actually on d8 in their engine... but the board shows Kd7 with legal moves Kc7 etc. Ke6/Kc7/Kc8/Ke8/Ke7 — all adjacent squares to d7. Bd6 is the odd one. If check were along the d-file from... Rd1! Wait Rd1 — d-file: d1 to d7: d2? empty (pawn moved? No, d2 pawn — White pawns a2,b2,c2,f2,g2,h2 — d-pawn gone, d2 empty!). Rd1 attacks d2... d3, d4, d5, d6, d7! But wait, knight was on d6 until it moved to f7, blocking. After Nxf7, the rook d1 now attacks d7! That's the discovered check! Yes! So check from Rd1 along d-file. Block on d6, or move king, or capture? Bd6 blocks. King moves: c6 is occupied by own pawn... c6 has black pawn. Kc6 illegal (occupied). Legal: Bd6, Kc8, Ke8, Ke7, Ke6, Kc7. Ke7 — is e7 safe? Rd1 doesn't attack e7. Knight f7 attacks e5, d8, h8, g5, d6, h6 — not e7. Bishop e3 attacks e-file? e3-e4-e5 blocked by pawn e5. Diagonals: d4,c5,b6,a7 / f4,g5,h6 / d2 / f2. Not e7. So Ke7 legal. Now evaluate: knight on f7 attacks h8 rook. If I block with Bd6, knight takes h8, then... I'd be down a rook (already down 4). If I play Ke7, knight takes h8 too. Hmm, can I save the rook? Rh8 — knight f7 attacks h8. I could move... rook can't move (in check must address check). Block Bd6 keeps rook en prise still. King moves don't save rook. Actually wait — after knight takes h8, do I have counterplay? Let's think about Bb7: after Nxf8? The knight on f7 could also take g7? Actually after Nxh8, the knight is trapped-ish on h8 (g8 empty? yes g8 empty; knight h8 can escape via g6? h8 knight moves: g6, f7. g6 — then I can trap it?). Material: down 4. Losing anyway. Best practical: play Bd6 to block, then after Nxh8, Bb7xf... hmm. Or Ke7 then knight takes h8, then I play Bxg2? or Bh6? Let me think. Actually, alternative: after Bd6 block, threat? White's knight takes h8, then Bb7 attacks f... Bb7 attacks e4, c8... My bishop d6 and b7. Black bishop f8. Plan: Nxh8 Bxh8? No — bishop f8 can't reach h8. g8 empty... Let's count material after Nxh8: White up: R for nothing? Currently down 4 (25 vs 21). After losing rook: down 9. Ouch. Is there a better block? Bd6 — then also Be7? Not listed. Bd6 keeps bishop attacking... after Nxh8, I have Bd6, Bb7, Bf8 vs Be3, Bf1. Could I win the knight back? After Nxh8, knight trapped: my g7 pawn... knight on h8, moves g6, f7. If it goes g6, hxg6? No wait it's White's knight; I capture with h7 pawn? Knight on g6 attacked by h7 pawn and f5... Actually after Nxh8 g6 later hxg6 wins it back? But White wouldn't allow immediately. Alternatively Ke7, then after Nxh8, ...Bg4!? threatening... hmm. Or maybe better: Ke7 and if knight takes h8, I play Bxg2 winning a pawn? Or Bh6 trapping? Actually after Nxh8, Rh8 gone... I mean rook captured. My pieces: Ra8, Bb7, Bf8, Bd6? no Bd6 if Ke7. Let me just pick Bd6 blocking — wait, does Bd6 do anything else? It attacks... h2! Bd6 attacks h2 (d6-e5? no that's my pawn... diagonal d6-c5-b4-a3 and d6-e7-f8(own). Other diagonal: d6-c7? c7 empty, b8... d6-e5(own pawn) blocked. So Bd6 threatens nothing. Alternative: Be7 — is it legal? Not listed. Listed: Bd6 only block. Or king move Ke7 then after Nxh8, ...Bh6!? attacking... hmm. What about counterplay with Bb7xf... nothing. Let me reconsider Ke7: after 14...Ke7 15.Nxh8 — knight on h8 is trapped? White knight h8; can I trap it permanently? Bf8 covers g7... knight escapes via g6 or f7. f7: attacked by nothing? g6: attacked by h7 pawn. White would play Nf7 or Ng6. Ng6 hxg6 wins knight. Nf7 — attacked by? my bishop? Bf8-e7? Hmm Nf7 could then fork? Actually knight on f7 attacked by Ke7! So after Nxh8, if knight tries Nf7, Kxf7. Ng6 hxg6. So knight is truly trapped on h8 and I win it back next... no wait, it's not attacked on h8; it's trapped — White must eventually lose it or shuffle. But can it shuffle h8-f7-h8? Nf7 met by Kxf7. So yes, knight on h8 is doomed; White gets maybe one pawn for it (Bxg2 etc.). So Nxh8 nets: I lose rook (5) but regain knight (3) and White gains g2/h2 pawn stuff? Let's see: after Nxh8, my plan Bxg2 wins a pawn back. So net: -5 +3 +1 = -1 plus existing -4 → down ~5? Hmm. Actually alternative: maybe I shouldn't let it. Is there any way to save the rook AND address check? Block Bd6 — rook still attacked. No. Alternatively — wait, can I capture the checking rook? No. Can I capture knight f7? Kd7 can't reach; Bb7 attacks f... b7-c8? no; b7-a6, b7-c6(own), b7-d5, e4... b7-c8? c8 empty — Bc8 block! Is Bc8 legal? Not listed. Hmm, Bc8 would block? Check is from d1 along d-file; b7-c8 doesn't intersect d-file. Not legal. So Bd6 it is? Or a king move. Which is better? Bd6 keeps king more active? But Bd6 hangs to what? White Be3 attacks d... after Bd6, is bishop d6 attacked? Be3 attacks d4... no. Knight f7 attacks d6! Nxd6. Hmm! After Bd6, White could play Nxh8 anyway (rook hanging). So Bd6 doesn't save anything, but it keeps bishops. Compare Ke7: after Nxh8, my king on e7 — active, and knight trapped. Also after Ke7 I threaten... Bb7 attacks nothing immediate. Actually consider Ke7 then knight takes h8; then ...Bg4! ideas: Bg4 attacks... threatens? Or after Nxh8, ...Bf6!? eyeing... Actually simple: Nxh8, then ...Bxg2 (Bg4xg2? my bishop b7 to g2: b7-c6? blocked by c6 pawn... b7-g2 diagonal: c6 own pawn blocks. Hmm. Bf8xg2? f8-g7(own pawn)? blocked. h7-g... no bishop. So Bxg2 not possible. Bh6 from f8? f8-h6: g7 own pawn blocks. OK. So after Nxh8, my extra play: attack the trapped knight with g7...? Knight h8 not attacked; I can attack with Bf8? No. Hmm, actually to win the knight I need it to move to g6 (hxg6) or f7 (Kxf7) — White might just leave it there for a long time while playing elsewhere; it's still a piece for the moment (though passive). White is up rook then. Alternatively, maybe don't allow Nxh8 to be so free: Bd6 blocks and after Nxh8, ...Bc7!? hmm no. Actually, wait — what about Be7 as block? Check along d-file... Be7 doesn't block. Only d6 blocks. Could I counter with Bb4+? No, in check. Decision: Bd6 or Ke7. With Bd6, knight f7 attacked by my bishop — if White plays Nxh8, then Bxh8?? no. Hmm, bishop d6 doesn't attack f7. Knight f7 attacks d6 — so Bd6 hangs the bishop to the knight, but knight would rather take h8. If White takes Nxd6 instead, I keep material equal-ish? Nxd6 cxd6? No — c6 pawn can capture d6! cxd6. So after Bd6 Nxd6 cxd6, material: I traded bishop for knight — bad for me (down a bishop then). White would prefer Nxh8. With Ke7: knight goes h8, trapped. I'd say Ke7 is more natural, keeps bishops on long diagonals, king active. Also Ke7 — is king safe there? White pieces: Be3, Bf1, Rh1, Rd1, pawns. Attacks on e7: none as computed. Then plan: 14...Ke7 15.Nxh8 — hmm wait, does White have better than Nxh8? White could play Nd6!? forking? Knight f7-d6: attacks... b7? No, d6 knight attacks b7? d6→b7 yes! And c8, e8, f7, f5, e4, c4, b5. So Nd6 attacks Bb7 and... Kxf? No, king e7 — knight d6 gives check? d6 attacks e8, f7, f5, e4, c4, b5, b7, c8 — not e7. Nd6 attacks Bb7 and Bf7? no. Attacks b7 bishop and... also Nxc8? So Nd6 wins bishop b7? King e7 doesn't defend b7. Hmm! So after 14...Ke7 15.Nd6! attacks b7 bishop; bishop moves, 16.Nxc8+ Rxc8? no wait knight takes c8 then rook a8 takes c8. Knight forks? Nd6 threatening Nxb7 and also... it also blocks my development. Alternatively 15...Bc8 covers c8? Then Nd6 attacked by? Ke7? No — e7 attacks d6? King e7 adjacent to d6 yes! Kxd6? Is d6 defended? By Be3? e3 attacks d4... no. f7? Knight left f7 when going to d6. So Nd6?? Kxd6 wins knight. OK so Nd6 is bad for White. So White plays Nxh8. Alternatively after Ke7, White plays Nd6 forking? Let me recheck knight from f7 to d6: does it give check to Ke7? Knight d6 attacks: b5, c4, e4, f5, f7, e8, c8, b7. Not e7. And Kxd6 — d6 defended by c5? No white pawn there. Be3 defends d4 not d6. So Nd6 loses knight to king. Good, so after Ke7, White's best Nxh8, knight trapped, I chase it. Also I could try ...Bg4 ideas. Also alternative 14...Kc7!? keeping king on queenside — but knight fork Nxd6? Nf7-d6 check! Knight d6 attacks c8, e8... and check? King c7: knight d6 attacks b5, b7, c8, e8, f7, f5, e4, c4 — not c7. Nd6 attacks b7 bishop and threatens Nc4/Nb5+? Nb5+ check to c7? knight b5 attacks c7 yes. So Kc7 runs into Nd6 annoying. Ke7 better. Also 14...Ke6!? — king e6, is it safe? Knight f7 attacks e5, g5, d6, h6, d8, h8. Not e6. Be3 attacks? e3-f4-g5; e3-d4; no. Bf1: f1-a6 diagonal — b5, c4, d3, e2 empty... f1 to e2-d3-c4-b5-a6. Not e6. Rh1? h1-e1? no, e6 not on file. So Ke6 safe but weird; Ke7 better, supports chasing knight? King e7 covers f7 and g6? f7 yes (adjacent). g6 no (knight distance... e7 to g6 is knight move, no). Anyway. Also consider Bd6 line more: 14...Bd6 15.Nxh8 — then knight h8 trapped similarly, and my Bd6 was attacked... after knight leaves f7 for h8, Bd6 no longer attacked. Bd6 also is solid, connects? Then ...Bb7, ...Ra8-b8 etc. King still on d7. Which is better, Bd6 or Ke7? With Bd6, my bishop d6 vs White Be3... Also Bd6 allows ...Bb7 ideas. Hmm, but with Ke7 my king is active and knight truly dominated (Kxf7 option). With Bd6, knight trapped on h8 too (Ng6 hxg6? wait my h7 pawn, yes; Nf7 — attacked by nothing then! With king on d7, Nf7 is safe and it can go back f7-h8 or f7-d6? or f7-e5 winning e5 pawn? f7 knight attacks e5! So with Kd7, knight isn't trapped: Nf7 attacks e5 and d6-bishop. So Ke7 is clearly better — king controls f7, trapping knight on h8 fully. Also with Ke7, is my e5 pawn defended? Yes by king. After Nxh8, White might try Nd6?? no. White could play Bd4 or g4 etc. Choose Ke7. Quip: something about the knight going deep into the corner never to return.

I see it — 14.Nxf7+ was a discovered check from the rook on d1, and the knight is eyeing my h8 rook. But if my king steps to e7, it guards f7, and any knight that ventures to h8 will find itself in a prison with no exits. The rook may fall, but the knight will rot in the corner.

GLM 5.3 High· move 15

Knight on f7 attacked? King on e7 adjacent to f7 — yes, king attacks the knight. So knight must move or capture. Nxh8 wins rook but knight gets trapped in corner. Bc5+ is check... let's evaluate. Bc5+ Ke8 (king can't take? King e7, bishop c5 — Bc5 attacks e7. King moves: Ke8, Kd7? Kd7 attacked? c5 bishop covers d6, b7 black bishop... Ke7→Kd7 possible? d7 adjacent to... nothing white attacking? Actually after Bc5+, black king can move to d7 or e8, or block with Bf8-d6? No, check from c5 along diagonal c5-d6-e7. Block on d6: Bxd6? Bishop f8 can't reach d6. Rook? No. So king moves: Kd7, Ke8, Kf6? e7→f6: attacked by knight f7? Knight on f7 attacks d8, d6, e5, g5, h6, h8. Not f6. King f6 possible? e5 pawn... wait e5 is black pawn on e5, f6 is empty. Kf6 then knight f7... King on f6 could then capture knight? No, knight would move. Hmm. Actually better: Nxh8 wins exchange+ more. Knight escapes via g6? From h8, Ng6 no — h8 to g6 yes knight moves h8→g6. Then king can capture g6? King on e7 covers f6, f7, f8... not g6. Bf8 covers g7... Ng6 then Nf4 or Ne7? Actually knight h8 can go g6, and from g6 to f4/e7/h4/e5? Let's check: after Nxh8 Kd7?? Then Ng6 escapes. Black bishop b7 covers g2 diag... g6 not covered. So Nxh8 wins a rook, knight likely escapes with Ng6. That's winning a full rook basically. But wait, knight on f7 — if Nxh8, is it safe? King e7 can't reach h8. So Nxh8 wins rook. Then knight trapped? h8 knight: Ng6 possible if g6 empty — yes. Then black king can't easily trap. So Nxh8 wins rook. Alternative Bc5+ forks? Bc5+ Kd7?? no, Bc5+ then Nd6+?? Actually Bc5+ Ke8, then Nxh8 anyway with extra tempo. But Bc5+ allows Kf6 hitting knight? Kf6 attacks knight on f7? No, f6 adjacent to f7 — yes! Kf6 attacks the knight. Knight on f7 attacked by Kf6, and f7 knight must move; Nxh8 then Kf7 traps? After Nxh8 Kf7, knight cornered, but White up material. Hmm, but Bc5+ Kf6 then Nxh8 Kf7 and knight... Ng6?? no wait king f7 covers g6. So knight trapped after Kf7? Knight h8 has no moves (g6 covered by Kf7). But material already up 4 plus rook. Actually white is up 4 already; Nxh8 makes up a rook, even if knight eventually lost, net +exchange... Actually if knight trapped and lost, net gain rook-for-knight later. Still good. Simplest: Nxh8 directly. Black's threat after Ke7 was to trap/take knight. Nxh8 immediately: knight h8, black king e7 far. Ng6 escape next move unless Black plays Bg7?? no... Black could play Rd8, then Ng6 fine. So Nxh8 wins rook cleanly. Best move: Nxh8.

Told you — security deposit collected. Say hi to the corner for me, little knight.

GLM 5.3 Flash High· move 15…

Position: White knight trapped on h8. Black to move. The knight on h8 is trapped by h7 pawn and g7... wait, g7 pawn present, h7 pawn. Can we trap it and win it? Kxh8? No, king can't reach. The knight is stuck: h8 knight can go to g6 or f7. g6 attacked by... nothing? Bc8 covering g6? Bb7 is on b7. Actually h8 knight escape squares: f7, g6. f7 attacked by? Ke7 covers f7? Black king on e7 — yes, king covers f7? King on e7 attacks f8, f7? e7 to f7 adjacent — yes. So f7 covered by king. g6: covered by? Not covered currently. So h6/g6... If we play g6, locking? Actually play g6 covers g6? No, pawn on g6 doesn't cover g6. Pawn on h7 covers g6! Wait black pawn on h7 covers g6. So knight's escape squares f7 (covered by king) and g6 (covered by h7 pawn). Knight is trapped! White must play g4 or similar to free it, but meanwhile Black can develop. Actually with e5 pawn, Black can also play ...Bc8 attacking? Or just grab more material / develop. Knight trapped means White will lose a piece eventually (needs Bh6/g5? White Bf1 can't easily). White Bf1 covers h3... To free knight, White needs pawn break g4? Knight g6 escape also covered by h7 pawn permanently. So Black should just develop and grab. Also white's Be3 and Bf1 hanging? Bf1 attacked by Bb7? b7 bishop diagonal b7-g2: c6 blocked by black pawn c6. Be3 attacked by e5 pawn? No, e5 pawn attacks d4/f4. Be3 is fine. Rh1 attacked by Bb7? No. Best moves: Re8 or Rd8, develop. Also e4 idea: e4 attacks Be3. After e4, Bxe4?? then Rd1... Actually e4 Be3x? Be3 can't take e4? Be3 to e4? Bishop on e3 can capture e4? e3-e4 diagonal? e4 is diagonally adjacent from e3? No, e3 to e4 is vertical. Bishops don't move vertically. Wait bishop on e3: diagonal squares d4, f4, d2, f2... e4 not reachable. So e4 attacks Be3. Be3 moves, then... e4 also blocks? Hmm e4 would be met by Bxe4? no. Q gone. Be3 must move (Bf4, Bd2, Bc5? d4?). Then Rd8-pin ideas: Rd8 pins Rd1? Rd8 vs Rd1 with king? King on c1 — pin via d-file? Rd1 on d-file, king c1 not behind. No pin. Also threat: Bc8 trapping knight further and attacking? Let me consider Rd8: attacks Rd1. Rd1 defended by Be3 and Bf1? Bf1 covers d1? No, f1-e2-d3... no. Rd1 defended by Be3? e3-d2... no. Rd1 defended by king? No. Rd1 defended by nothing? King c1 doesn't cover d1. Rd1 undefended! Rd8 attacks it — then Rd1 moves, we get... nothing gained immediately. Actually Rd8 then Rd1 must move; meanwhile knight h8 stuck. But is Rd1 defended? Be3 defends d2, f2... not d1. So Rd8 wins tempo. Also Rb8 pinning b2? Kc1 not on b-file. Also consider e4 immediately attacking Be3: 15...e4 16. Bf4/Bd2/Bc5 then Rd8. But e4 leaves e5 empty; fine. Better plan: play Rd8 hitting Rd1 and later Rc8/Rb8. Or develop bishop Bc8 hitting h3? Bc8 attacks... h3 via g4? Not yet. I'll play Rd8, attacking the loose rook d1. Quip about the cornered knight.

The knight on h8 is sealed in — its only exits are f7 (my king says no) and g6 (my h-pawn says hello). Time to pile on: Rd8 hits the loose rook on d1.

GLM 5.3 High· move 16

Position: White is up material. Black threatens Rxd1+? Rook d8 attacks d1 rook, but White king c1. Rxd8 would trade. Knight h8 is trapped but Black can't easily capture it. Strongest move: Rxd8+ winning the exchange? Actually Rxd8 Bxd8 — then knight on h8 is trapped still. Or keep tension with Ng6+!? Let's evaluate. Black's threat: Rxd1+ Kxd1 then knight h8... after Rxd1+, White recaptures. Let's consider Ng6+ first: check? Ng6+ from h8: knight on g6 attacks e7? Knight g6 attacks f8, h8, e7, e5 — yes attacks king on e7, so check. Black responses: Kf7 attacks knight g6? f7 attacks g6 yes. Kd7, Ke8, Kf8? f8 occupied by bishop. Also hxg6 possible? h7 pawn can take g6? h7 pawn captures g6 — yes if knight moves there, hxg6 possible... wait check: knight moves to g6 giving check; pawn h7 can capture g6, resolving check. So Ng6+ hxg6 loses knight for pawn? Knight on h8 would be captured after Ng6+ hxg6. But knight was trapped anyway; trading it for a pawn is bad-ish, but knight was lost anyway? Actually knight on h8 is trapped but Black can't capture it (nothing attacks h8). Knight could escape via Ng6+ or Nf7. Best move likely Rxd8: after Rxd8 Bxd8 (forced? Kxd8 impossible — king e7 can't take d8? d8 adjacent to e7 yes! Kxd8 possible... wait after Rxd8+ it's check to Ke7? Rook on d8 attacks e7? Rook on d8 attacks along rank 8 and file d. King on e7 is not attacked by rook on d8 — d8 and e7 diagonal, not rook line. Wait, Rxd8 is not check. Black recaptures with Bxd8 or Kxd8. Then Ng6+ escapes knight with check! That's nice: Rxd8 Kxd8/Bxd8 Ng6+ forking king and... attacks e5 pawn, king moves, Nxe5 or knight escapes via f8? Actually knight g6 attacked by king on d7/f7. Sequence: 16. Rxd8 Kxd8 (or Bxd8) 17. Ng6+ Kd7 (if Kd8) then knight... Nf8 or Nh4 escapes. Knight escapes to f8 then Nd7? Hmm. Alternatively 16. Ng6+ hxg6 17. Rxd8+ Bxd8 Rxd8? no, only one rook. After Rxd8+ Bxd8 then... White up 9 minus knight = up 8, fine, but better keep knight. Actually check Rxd8 Kxd8: is king allowed to take? After Rxd8 Kxd8, knight h8 still trapped, Ng6+ then Kd7 attacks g6? d7 to g6 not adjacent. Knight g6 checks king on d8? Knight g6 attacks e5, e7, f8, h8 — not d8. Wait I said Ng6+ checks Ke7; if king recaptures on d8, then Ng6 is not check. King on d8, knight escapes via Ng6, then Black plays Bf8-h6? Let's compute: 16 Rxd8 Kxd8 17 Ng6 hxg6 18? loses knight. Knight escape squares from h8: f7 and g6. After Rxd8 Kxd8, Nf7?? attacked by... Bf8 covers... bishop f8 attacks g7, e7, d6 — not f7. Nf7 attacked by king d8? no. Kd8 to e8/e7 could attack f7. Nf7 threatens Nd6? or Nh6. Hmm, Nf7 then Ke8 attacks knight; Nh6, gxh6 loses knight. Ng5 escapes! From h6 knight goes g5? Nh6 then gxh6... h6 knight: pawn g7 captures h6. Hmm. Alternatively 16 Rxd8 Bxd8 17 Ng6+ (king on e7, check!) Kf7? no wait hxg6 possible — pawn on h7 takes g6, but is that legal while king in check? Check from g6 knight; capturing the knight resolves. 17... hxg6 and knight gone, but we traded R for R+B and knight... We gave knight for pawn. Still up material massively. Maybe simpler: keep rook, play Ng6+ immediately when it's a check. 16. Ng6+ hxg6 17. Rxd8+ Bxd8 18. Kd2 or Re1... White up: material currently 25 vs 16, trading knight for pawn h7 → 23 vs 17? Wait knight captured = White loses 3, Black loses 1 pawn. Then rook trade even. Net up 8. Meh. Better: 16. Bc5+!? Check from c5? Bishop e3 to c5: e3-d4-c5 diagonal, yes Bc5+ check to Ke7. Black plays Kf6? d6? Ke8, Kd7, or Rd1+?? Rxd1 Kxd1 then Bxd6?? Hmm. After Bc5+ Black could play Rxd1+ Kxd1 then king escapes check... wait after Bc5+ Rxd1+ Kxd1 the check from c5 still — c5 attacks e7-d6... bishop on c5 attacks d6, e7 — king no longer on e7. Then White is up, and knight h8 still trapped though. Actually the knight on h8: is it really trapped? Escape squares f7 (attacked by king e7? no, e7 adjacent to f7 — yes! king on e7 attacks f7). g6 (attacked by h7 pawn and king e7? e7 not adjacent to g6). So f7 covered by king, g6 covered by h7 pawn. Knight trapped unless king moves or check forces. Plan: 16. Rxd8 first! Then whichever recapture, king likely moves off e7 or not. If 16...Kxd8, then 17 Ng6! (no check, but escaping) — knight on g6 attacked by h7 pawn: hxg6. Hmm. If 16...Bxd8, then 17 Ng6+ and now king on e7: hxg6 recaptures. Bad. Alternative: don't save the knight; it's only a knight and you're up 9. Just play Rxd8+ wait Rxd8 is not check. Play strongest: Rxd8 wins rook for rook? No — even trade. Hmm, what about Rd7+!? Rook d1 to d7+: rook on d7 attacks e7 king. Rd7+ Kxd7?? no king on e7 can capture d7 — Rd7+ is protected? Nothing protects d7. Rd7+ Kxd7 just loses a rook. Bad. Rd7+ actually rook would be adjacent to king, Kxd7. Illegal blunder. No. Bc5+ analysis: 16. Bc5+ Ke8 (or Kf6? f6: attacked by? nothing; Kf6 possible; then Rxd8+? no rook trade... after Kf6, White Rd7 wins? Let's see 16 Bc5+ Kf6 17 Rxd8 Bxd8 18 Bxd6? no d-pawn gone... anyway). Or 16...Kf8 17 Bxd6? no pawn d6 doesn't exist... wait move 10...d6, so pawn on d6? Board shows Black pieces: no d-pawn. 10...d6, then 12...e5 — d6 pawn still there? FEN says Black pieces: a7,g7,h7,c6,e5 — no d6. Hmm, 13. Nxd6+ Kd7 captured d-pawn. Right. 16. Bc5+ Ke8?? then 17 Rxd8+! Kxd8 18 Bxd6... wait bishop d6 checks? After Rxd8+ Bxd8 (bishop f8? f8 bishop could take d8: yes Bxd8) — messy. Let me just find clean line: 16. Rxd8 Bxd8 (Kxd8) 17. Ng6+ if... after Kxd8, Ng6 no check. After Bxd8, king on e7, Ng6+ hxg6. What about 16. Ng6+ first only if hxg6 forced... it's check; options: Kf7?? attacked... Kf6? f6 not attacked by knight g6? Knight g6 attacks f8,e7,e5,h8 — Kf6 legal? g6 knight doesn't attack f6. King f6 then knight g6 attacked by king? f6 adjacent to g6 — yes. But White could respond: Nxe5! no wait. After 16 Ng6+ Kf6 17 Ne7!? or Nf8. Hmm. Alternatives to check: Ke8, Kd7, Kf7? (f7 attacked by knight g6? No, g6 attacks f8,h8,e5,e7. f7 not attacked — but wait, if king moves to f7 and knight g6 then... Kf7 attacks g6, knight must flee: Nf8+? knight to f8 forks? Nf8 check? f8 knight attacks d7,e6,g6,h7 — not f7. Nh4, Ne7? attacked by Kf7? e7 adjacent f7 yes. Kh4?? hxg6... knight moves: Nh4 (g6→h4? no, that's not a knight move; g6 knight moves to h4? g6-h4 is knight move, yes). Nh4 attacked by...g5 pawn? no g-pawn on g7. Nh4 then Bf8 covers? bishop f8 attacks g7... Nh4 safe-ish, then Bg5+! from e3. Getting complicated. Simplest strong plan: the knight is a lost piece essentially; convert to trade favorably. Actually wait — after Rxd8 Kxd8, knight h8: Nf7! attacked by king? d8 not adjacent f7. Nf7 safe. Then Nxd6?? no pawn. Nf7 then Bd8 covers f7? bishop on d8 after Bxd8. Hmm after Rxd8 Bxd8 bishop covers f7? d8-f7: no, diagonal d8-e7-f6. Not f7. Let's pick concretely: 16. Rxd8. Black recaptures Kxd8 or Bxd8. Case A: 16...Kxd8. 17. Nf7+! Is that check? Nf7 knight attacks d8, d6, e5, h6, h8, g5. Attacks d8 — check! 17...Kc7/Ke8/Kc8/Kd7? d7 attacked by knight? No. Kd7 then knight... Nf7 safe. Knight escapes with check! Great. Then 18. Nd6 or Nh6/Bg5+ etc. Knight saves itself. Case B: 16...Bxd8. 17. Ng6+ (check to Ke7) hxg6 18... hmm knight gone. But then bishop pair gone... Material after: White gave rook+knight, got rook+bishop? Wait Rxd8 traded rooks? No: Rxd8 Bxd8 = rook traded for rook. Then Ng6+ hxg6 = knight for pawn. Net: lost knight for h-pawn, but knight was trapped anyway. White still up ~8. Case C: 16...Bxd8 alternative: 17. Ng6+ Kd7?? then knight escapes: Nf8 or Nh4? Kd7 attacks? d7 adjacent to... not g6. Then Nf8 safe. Even better. Or avoid Case B loss: 16. Bc5+! forces king move first, then Rxd8+ and knight escapes? 16. Bc5+ Kd7?? attacked by... Kd7 then Rxd8+ Kxd8 Bxd6? Bishop c5 attacks d6 — check? Bishop on c5, king d8 after Kxd8: c5-d6-e7-f8 diagonal doesn't hit d8. Not check. 16. Bc5+ Ke8 17 Rxd8+ Rxd8?? only bishop can recapture: Bxd8 then Rxd8?? no. 17 Rxd8+ Bxd8 18 Bxd6? d6 empty. Hmm. 16. Bc5+ Kf6!? king gets active. Then 17. Rxd8 Bxd8 18. Ng6! now king f6 adjacent g6... 18 Ng6 hxg6 no wait king f6 attacks g6: Kxg6. Bad. 16. Bc5+ Ke7... wait check forces king to move or block. Block options: nothing (Rd8 can't block c5-e7... d6 square: Rd8 can't reach d6). King moves: Kd7, Kf7, Ke8, Kf6. - Kd7: 17 Rxd8+ Kxd8 18 Nf7! check? f7 attacks d8 — yes check! Great, knight escapes with check. Then Bxf7+ Bxf7?? bishop e3? no — after Nf7+ Kc8/Ke8, knight safe. - Ke8: 17 Rxd8+ Bxd8 18 Nf7? attacked by Ke8. 18 Ng6 no check, hxg6. Hmm. - Kf6: 17 Rxd8 Bxd8 18 Ng6? Kxg6. 18 Nf7+ check? f7 attacks d8,d6,e5,h6,g5... not f6. No check. Kxg6? king f6 attacks... Nf7 attacked by Kf6? No, f6-f7 adjacent — yes! Nf7 loses. - Kf7: attacks f7/g6 squares... 17 Rxd8+ Kxd8 18 Nf7?? no. Hmm. So Bc5+ doesn't uniformly save knight either. Simplest: 16. Rxd8 and accept knight might be traded for pawn in worst case while being up 9. Actually in Case B (Bxd8, Ng6+ hxg6), White nets: rook trade + knight for pawn. Fine. But is there better: 16. Rd7+?? Kxd7 loses rook — no. What about just 16. Rxd8 being best practical move anyway (removes their rook). Or 16. Bc5+ Ke8 (Kd7) — engine would probably say Rxd8 or Bc5+. Actually, consider 16. Bc5+ Ke8 17 Rxd8+ Bxd8 18 Bh6! trapping bishop d8? Bh6 attacks f8 empty... pins? Bishop d8 defended by king e8. Then Ng6 hxg6... no. Or after 16 Bc5+ Kd7 17 Rxd8+ Kxd8 18 Nf7+ knight escapes with tempo — excellent line. But other king moves less good. I think the cleanest: 16. Rxd8. If Kxd8, Nf7+ escapes with check. If Bxd8, Ng6+ and knight gets traded for pawn — acceptable, or maybe better: 16...Bxd8 17. Bg5+!? Bishop e3 to g5: check? g5-f6-e7: yes Bg5+ is check! Then 17...Kf6 (or Ke8, Kd7, Kd6?? attacked). 17...Ke8 18 Ng6?? no. Hmm Bg5+ doesn't save knight. 16...Bxd8 17 Ng6+ hxg6 18 Rd1?? no rook traded. Position: White up queen-equivalent anyway. Also 17...Kd7/Ke8/Kf7/Ke6?? — if not hxg6, knight escapes. hxg6 is best for Black. Fine — play 16. Rxd8. Quip about bellhop.

Black is down heavily. Legal moves include Kxd8 — capturing the rook with king. After Kxd8, White's Be3 and Bf1... Kxd8 is legal, and knight on h8 is trapped anyway. Position after 16...Kxd8: is it check? White king c1. White Bf1 could pin? Kxd8 — any white piece attacks d8? Be3 doesn't reach d8. So Kxd8 wins the rook, leaving White with knight h8 trapped, bishops. Material: White 25 -5 = 20, Black 11+5=16. Still down but best. Also Kxd8 attacks knight h8? No, d8 to h8 along rank: e8, f8 (Bf8 own piece) blocked. Kxd8 seems clearly best (alternatives are losing more). Then white might play Bd4+? Actually after Kxd8, knight h8 is dead (Bf1... h8 corner knight, White can round it up eventually with Bd4+? No, bishops go for it: Bd4, Bc3... anyway). Make move Kxd8 with quip.

White is up a lot. Position: Black king on d8. Knight on h8. Candidates: Ng6 forks... Ng6 attacks f8 bishop? Ng6 attacks f8 and h8→g6 attacks h8? Knight g6 attacks f8 bishop and e7, h8... Also Bb6+ is check: Be3-b6+? Wait bishop on e3, b6 diagonal e3-d4-c5-b6 — yes Bb6+ forks king d8... Bb6+ Kc8 (or Ke7... d7 covered by b6? Bb6+ king must move; Kc8, then Bxa7 forking? Actually after Bb6+ Kc8, a7 pawn is attacked by Bb6. Bxa7 just wins a pawn. Better: Ng6 forks f8 bishop and h... Ng6 attacks f8. Then Bxf... Black plays Bxg6? No black has no pieces to take g6 except... bishop f8 doesn't attack g6? f8-g7-h6 diagonal, no. Pawn h7 could take g6 after Ng6 hxg6? h7 pawn attacks g6. Yes hxg6. Then bishop f8 hangs to nothing. Better: Bb6+ first. Bb6+ Kc8 then Ng6 hxg6... hmm. Consider Ng6 hxg6, then Bb6+? King escapes... after Bb6+ Ke8? d7 covered by b6 bishop? Bb6 covers d8 and c7, d4... Ke7 possible: e7 not attacked by Bb6. Then Nxf8 anyway. Actually simplest: Ng6 forks? No, just wins exchange of knight for bishop? hxg6 loses h-pawn but Black recaptures pawn with pawn, knight for pawn bad. Compute Bb6+: check. King moves: Kc8, Ke7 (e7 attacked by? nothing), Kd7? d7 attacked by Bb6? b6-c7-d8, no d7. So Kd7, Ke7, Kc8. After Bb6+ Kc8 then Rg1... Also after Bb6+ Ke7, Ng6+? No, knight h8. Best line: Ng6 attacking f8 bishop and threatening... hxg6 recaptures. So Ng6 only works if h-pawn pinned or bishop defended. Not good. What about Bb6+ then win a7? Bb6+ Ke7, Bxa7 Bxa7? Bishop b7 can't reach a7... Bb7 to a7 blocked by a... a7 pawn, bishop b7 attacks a8, c8... not a7. So Bxa7 wins pawn and bishop b7 is then... after Bxa7, Rxa7? no rook. Black down more. Actually there may be bigger: Bb6+ Kc8 (if Kc8) then Bxa7 threatening? Also Bb6+ Kc8, Be3... Let's just find strongest move. Consider Ng6 hxg6 Bb6+ Ke7, Bxa7 wins pawn back — even trade knight for bishop+pawns? Knight (3) for bishop+pawn, roughly equal but we're up 9, fine but not best. Alternative: Bb6+ first: Ke7 (or Kc8/Kd7). If Kd7, Bd4? then bishop pair. Hmm. What about Rg1 to activate rook? We're massively up; simplest solid move. But strongest: maybe Bb6+ Ke7 then Ng6+!? No — knight h8 to g6 check? g6 knight attacks e7! Yes! Knight on g6 attacks e7. So plan: Bb6+ Ke7, Ng6+! hxg6? Then no check... wait Ng6+ is check to king on e7. hxg6 blocks? h7 pawn captures knight on g6, removing check. Then hxg6, but bishop f8 still... White played Bb6 so bishop left e3. After Bb6+ Ke7 Ng6+ hxg6, White has Bb6, Bf1, Rh1. Material: gave knight, took h... net: knight for h-pawn? No, knight traded for h7 pawn? hxg6 means black h-pawn captures knight. White lost knight (3) for nothing yet. Bad. So Ng6+ Ke... if king moves to e7 then Ng6 check but hxg6 defends. King must move from check though — Ke7 attacked by Ng6, hxg6 removes the knight, check resolved. That's just losing knight for pawn. Bad. So Bb6+: after Ke7, then? Bc5#? King e7, Bb6-c5... Bc5 attacks d6, e7? c5-d6-e7 yes Bc5+ would be check? Bb6 to c5 attacks e7 diagonal c5-d6-e7 — check. King escapes... Bc5+? is it mate? King e7: attacked by Bc5. Escape squares: d7 (attacked by? nothing... Bf1 covers c4... no), f8 bishop own. Actually check sequence Bb6+ Ke7, Bc5+? king goes... that's not mate. Just pick strong practical move. Bb6+ wins a pawn and pushes king around. Let's check Kc8 response: Bb6+ Kc8 then Bxa7 threatening Bxb7? Bishop a7 attacks b8... Black Bb7 guards? After Bb6+ Kc8, Bxa7 Bc8? Then... anyway we win a pawn and keep pressure. Alternatively Ke7/Kd7 then Bc5/Bd4+ keep checks, maybe fork a7. Bb6+ Ke7 then Bc5+? Actually Bb6+ Ke7, then Bc5 is not check... wait c5-d6-e7 diagonal — yes check! Ke7 attacked. King moves: Kf6?? attacked by Bc5? No... king e7: f6 attacked by? nothing. Hmm but then Bxa7? Let's evaluate simple: Bb6+ Ke7, Bxa7 wins pawn and bishop f8 still hangs? Bf8 attacked by nothing. Fine. Or Bb6+ Ke7, Bc5+ Kf6/Kd7, then Bxa7+? if Kd7, a7 bishop... Bxa7 forks b... Bishop takes a7, bishop b7 defends a... b7 bishop attacks a6... not. Honestly Bb6+ Kc8, Bxa7 with threat... also Ng6 fork a7/g6? Ng6 attacks... f8 bishop. And h... Alternatively consider winning bishop f8: Ng6 hxg6 no. What about Bf4 hitting e5 pawn? e5 defended by f6... nothing. Be3xf... Bf4 attacks e5, defended by? d6 gone, f6 empty. e5 pawn defended by nothing? Bishop f8 doesn't defend e5. So Bf4 just wins e5 pawn? Black could push e4? Then Bxe... Bf4 e4, then Bd... hmm Bf4 attacks e5; Black defends with... nothing can defend e5. So Bf4 wins a pawn. But Bb6+ also wins pawn with tempo (check). Strongest is probably Bb6+ followed by Bxa7. Let me double check after Bb6+ Kd7, Bxa7? Bishop b6 takes a7? b6-a7 yes. Then bishop attacks b8, and bishop b7... Black could play Bc8 pinning? Meh. Also after Bb6+ Ke7, Bd4!? threatening Re1? no rook is h1. Rh1-e1 impossible (f1 bishop on f1, e1 accessible via h1-g1-f1? f1 occupied by own bishop). Rook can go g1. Also consider Ng6 more: after Ng6 hxg6? Wait does h7 pawn capture toward g6? h7 black pawn moves down (toward rank 1), captures g6 — yes. I'll play Bb6+ with quip. Actually wait — check Kd7 legal? d7 square attacked by White? Bf1 covers... b5-c6-d7? Bf1 diagonal f1-e2-d3-c4-b5-a6, no. So Kd7 legal. Then after Kd7, Bd4 wins e5? e5 defended by... d-pawn gone. Bxd... Bf4/Bd4 wins e5 pawn. Or Bxa7. After Bb6+ Kd7, Bxa7 threatens Bxb7 and bishop b7 hangs? Bxa7 attacks b8... b7 bishop defended by king? d7 king doesn't defend b7. Bishop on a7 attacks b8, not b7. Hmm, Bxa7 then Bc8 defends. Still up pawn. Fine, Bb6+ it is. Actually also consider simply Ng6: attacks f8 bishop; if hxg6, then Bxf8? No, after Ng6 the f8 bishop... Ng6 hxg6 and f8 bishop free. But wait after Ng6, Black bishop f8 attacked; Black replies Bxg... can't. Black plays Bc5 attacking e3 bishop and defends? So Ng6 threatens Bxf8+ Kxf8? f8 bishop defended by king d8? No, king on d8 doesn't defend f8. So Ng6 attacks bishop f8 undefended — Black must move it or defend with hxg6 removing attacker. hxg6 wins knight for pawn? Knight was sacrificed... net: knight (3) for pawn h? No wait hxg6: black pawn takes knight. White lost knight, black lost nothing yet. Ng6 only good if Black can't take — h7 can take. So no. Bb6+ final. Quip about housekeeping/check-out theme.

Black is in check from Bb6. Legal moves: Ke8, Ke7, Kd7, Kc8, axb6. Best is axb6 capturing the bishop? Wait, check from b6 bishop on a7 diagonal... bishop b6 gives check to Kd8 along b6-d8 diagonal. axb6 captures it. But is axb6 legal? Pawn a7 captures b6. Yes.

Position: White up 6. Knight on h8 can be saved or given check. Nf7+ forks... after Nf7+ king moves, then maybe knight escapes via d6? Actually Nf7+ K moves, knight on f7 can be captured? Black king d8, bishop f8, pawn g7 — knight f7 attacked by g-pawn? g7 pawn attacks f6/h6, not f7. Bishop f8 attacks f7? No, bishop attacks diagonals: f8 goes e7-g7... not f7. King d8 doesn't attack f7. So Nf7+ Ke8 (or Ke7/Kc7), then knight can go Ng5? f7 knight can jump to d6+ or h6, g5. Also Nf7+ then Nd6+ forking? Nd6 Kd7 then... Nf7+ Ke7 then Nd6+? King can just take? No. Let's calculate: Nf7+ — king on d8, check from f7. King must move: Ke8, Ke7, Kc8, Kc7. If Ke8, then knight attacked? Ke8 attacks f7? e8 adjacent to f7 yes. So king could recapture? Wait it's check to king, king moves; if Ke8 attacks knight... actually after Nf7+ Ke8, knight attacked by king e8? e8-f7 diagonal adjacency, yes king attacks f7. Then knight moves: Nd6+ Kd7 then Nf5+? or Nb5. Hmm. Alternative: retreat Ng6 saving knight? Ng6 — attacked by? Bf7... knight on g6 attacks h8 etc. Black can play hxg... no pawn h7 attacks g6! h7 pawn can capture g6? No, pawn on h7 captures g6 — yes! Black pawns capture downward: h7 captures on g6. So Ng6 hxg6 loses knight. Actually it's saved by g7? Both pawns. Wait, knight is currently trapped on h8? g7/h7 pawns attack... h7 pawn attacks g6, g7 attacks f6/h6. Knight on h8: attacked by nothing, but escape squares g6 (covered by h7 pawn) and f7 (covered by king). So the knight is trapped, will be lost eventually. Giving Nf7+ is best — get check then save it. Nf7+ Ke7 (or Ke8). Let's evaluate king replies: - Ke8: attacks knight. Knight must move: Nd6+ Kd7 then Nf5+ Kd6? then Ng... knight escapes to f5, attacked by? e5 pawn? No, e5 attacks d4/f4. Knight f5 safe-ish. Or after Ke8 Nd6+ Kd7, then Nb5 threatening... knight escapes. - Ke7: attacks f7? e7-f7 adjacent yes. Then Nd6 (not check... d6 knight attacks e8? d6 knight checks king on e8, not e7). Nd6 then Kd7 attacks d6... hmm. Better after Ke7: Nh6? attacked by g7 pawn. Ng5 then f6/Nf7... knight on g5 attacked by h7? No h7 pawn attacks g6. g5 safe? Bishop f8 covers g7-h6 and e7... not g5. So Nf7+ Ke7 Ng5 then Nf3/h3 later, knight escapes. Also Ng5 threatens Nf7+... whatever. - Kc7/Kc8: then knight escapes via d6? Nd6 attacked by... after Kc8, Nd6+? not check; Nd6 Kd7 attacks. Better Nh6 gxh6 loses. Ng5 works: g5 then knight can go f3/e4/h3. But gxf6? g7 pawn... g5 attacked by g7 pawn? Black pawns move down: g7 captures f6 or h6. Not g5. So Ng5 safe. Then next Nf3 or Nh3 escapes. So Nf7+ followed by Ng5 (unless Ke8 then Nd6+ first) saves the knight while giving check. Good move. Check that Nf7+ is legal: knight h8 to f7, gives check to Kd8? f7 knight attacks d8? Knight on f7 attacks d8 (f7->d8: -1 file... f to d is -2, 7 to 8 is +1, yes). Check. Legal per move list. Make Nf7+.

I'm in check from Nf7. I'm down material massively but I have two bishops and Black to move. Options: Ke8, Ke7, Kd7, Kc7, Kc8. Also could I capture the knight? Bxf7 — wait, legal moves listed only king moves. Bb7 can't reach f7; Bf8 can't reach f7 (f8 to f7 is diagonal? No, same file, bishops move diagonally; f8-f7 is vertical). gxf7? No pawn on f... g7 pawn could capture f7? g7 pawn captures on f6, not f7. h7... no. So only king moves. Which is best? Knight on f7 attacks h8... actually knight on f7 gives check along... Nf7+ from f7 attacks d8, d6, e5, g5, h6, h8. King on d8 must move. Candidate: Kc7 heading toward kingside? Or Ke7 approaching the knight to maybe trap it? Actually Nf7 could be trapped: after Kc7, knight can jump to d6+ ... Kd6? Hmm. Knight on f7 escape squares: d6, d8, e5, g5, h6, h8. d8 and h8 are corner-ish. Could I trap the knight? Kd7 attacks f7? No, king on d7 attacks e6, e7, e8, c6, c7, c8 — not f7. Ke7 attacks f7! Then knight must move or... knight could take e5. Ke7 then Nxe5? No, knight on f7 attacked by king must move; squares: d6, d8, g5, h6, h8 (e5 adjacent? e5 is not reachable from f7 by knight; f7 knight moves: d6, d8, e5, g5, h6, h8 — yes e5 is a knight move from f7). Nxe5 possible from f7? f7 to e5: yes, that's a knight move (down 1, left 2). So Ke7 Ne5 then my bishop... Bf1 guards e5? Bf1-e2-d3-c4-b5-a6 diagonal — no. Rh1 on h-file, no. Actually after Kd7, threatening Nxf7? No. Better plan: trap knight? If Kc7, knight goes Nxd6? no—f7 to d6 is a knight move, and d6 could fork? Kc7 then Nd6, Kd6. Hmm. Simplest strong move: Kc7 maybe heading toward center. Or Ke7 trying to grab the knight. Let's evaluate: Ke7 — knight attacked. Knight moves: g5, h6, h8, d8, d6. Ng5+ is check from g5? g5 knight attacks e6, e4, f3, h3, e7? No g5 attacks e4, e6, f3, f7, h3, h7. Not e7. So Ng5 no check. Nxd6? f7-d6 not a knight move? f7 to d6: files f→d = 2, ranks 7→6 = 1. Yes, knight move. Nd6+ from d6 attacks e8, c8, b7, b5, c4, e4, f5, f7. Kc7? d6+ attacks c8, e8 — king on e7 not in check from d6. Hmm after Ke7 Nd6+? d6 attacks e8 and c8, not e7. So no check. Then Nxc8? no. So after Ke7, knight retreats Ng5 or Nh6 (h6 attacked by? nothing; then Nf5 next). Meanwhile my bishops: Bf8, Bb7. I could then play Bc5+? no, wrong color bishop... Actually let me think: I want to attack f2/h2 pawns. After Ke7, knight likely Ng5 or Nh6/Nf5. Then I could develop: Bc5+, Bd6, Rh8. Alternatively Kc7: knight escapes g5/h6, attacks h7/g7 pawns. My pawns on g7, h7, e5, b6, c6. Which king move is best? Consider knight trapped scenario: Kc7, then Nxd6?? no. Actually Kc7 doesn't attack anything. Ke7 attacks f7, forcing knight to move, gaining tempo. Knight moves: Ng5 (heading f3 or h3), Nh6 (heading f5/g4), Nd6/Nd8/Nh8 (bad-ish, h8 trapped like earlier White knight went Nxf7+... wait White's knight is the one on f7; earlier Black's knight was on h8 captured? Actually White's N captured on h8 earlier: 15. Nxh8 Rd8 16. Rxd8 Kxd8 — hmm that traded rook for rook, but board shows no knight on h8... wait move 18 is Nf7+ — the knight that was on h8? No, history: 15. Nxh8 Rd8 16. Rxd8 Kxd8 17. Bb6+ axb6 18. Nf7+. That Nf7+ — which knight? White had knight on h8 after 15... no wait, White knight went Nc3-e4? Let me re-trace: 11. O-O-O Ne4 12. Nxe4 (white Nxe4) e5 13. Nxd6+ Kd7 14. Nxf7+ Ke7 15. Nxh8 — so White's knight captured h8 rook, sitting on h8. Then 15...Rd8 16. Rxd8 Kxd8 17. Bb6+ axb6 18. Nf7+ — knight from h8 to f7, check. Yes. So White's knight came from h8 and is now on f7. Funny. So Ke7 attacking f7: knight could go Nh6 (then Nf5+ next? f5 attacks e7 — yes Nf5+ check later). Or Ng5. Is there any tactic? I have bishops Bb7 and Bf8. Idea: after Ke7, if Nh6, then ...g5 trapping? Rh1 on h1. Bishop Bf1 covers h3. If knight goes g5, could trap with? Not really. Also candidate: Kd7 — no tempo. Ke8 similar. I think Ke7 is fine: gain tempo, then push e4 or develop. Actually consider: Ke7, Nh6 — then Bc5+? Bf8-b4-c5: Bc5+ from c5 attacks e7? c5 to e7 diagonal yes, check. But is Bc5 possible? Path f8-e7-occupied by king. Bf8 to c5: f8-e7(d1)... e7 occupied by own king. Not now. Later. Alternative: Ke7, Nh6, then e4 strong move supporting d... hmm. Also consider Kc7 then my e4 next. Let me just pick Ke7 — wins tempo. Actually wait: does Ke7 hang anything? Knight could fork: Nxd6 from f7 attacks... d6 knight attacks b7 (my bishop!), c8, e8, f5, f7... After Ke7 Nd6, then Nxb7! Knight takes bishop on b7 — b7 adjacent? d6 knight attacks b7 yes. Is b7 defended? No. That loses a bishop. But then my king... after Nxb7, Kd7 attacks the knight? d7 knight on b7: no. Hmm, but knight on b7 trapped? Squares from b7: a5, c5, d6, d8. Kc8 could trap: then Nb... Let's see: Ke7 Nd6 18...Nxb7?? that's White's move. Actually sequence: my move Ke7 (move 18 black), White 19. Nd6 (or other). If White plays Nd6, then Nxb7 next losing bishop, but my king could... After 19...Nxb7 20. Kd7 Nb5? wait my move 19 is between. Let me redo: 18...Ke7 19. Nd6+? d6 doesn't check e7. 19...Nxb7 20. Kd7 knight on b7 must move: a5 (then Kc... ), c5 (Kc6? attacks? c6 doesn't attack c5... hmm Kc6 attacks c5 yes), d6, d8. So knight might escape or be lost. Trade: knight for bishop, but I'm down 6 already; losing bishop for nothing is bad. Maybe avoid Ke7 then. What about Kc7? Then knight moves freely. Nh6 threat Nf5? f5 not check from c7. Or Nxe5? f7-e5 knight move: yes, Nxe5 capturing my pawn, then knight on e5, Nc7 fork? e5 knight attacks c6 (my pawn), d7, f7, g6, g4, f3, d3, c4. Not great for White. Kc7 also allows ...e4 next with bishops aiming. Also Ke7, Nh6, then g5 pushing pawn to trap knight? Nh6 attacked by g7 pawn? g7 pawn attacks f6 and h6! So after Ke7 Nh6, gxh6? wait g7 pawn captures on h6 — I can just take the knight with pawn! Yes! g7xh6. So Ke7 forcing knight off f7, if Nh6 then gxh6 wins knight. If Ng5, then knight escapes to f3/h3/e4... Ng5 attacked by? h-pawn? h7 attacks g6, no. So Ng5 safe, then Nf3 or Ne4. But gaining: knight goes g5, then I play e4? Actually also Bc5+? Not yet. Compare: Ke7 → knight best Ng5. Then I play e4 (attacking Ng5? e4 pawn attacks f5, d5, no). Bf8 activity: Bd6, Bc5 later. Ng5 then Nf3 hitting... f3 then my Rh1? Rh1 on h1, Nf3 attacks h4, g1, e1, d2... not h1. Hmm knight g5 could go f3 next; if Nf3, Bxf3? No my bishops can't take. gxf3? No pawn on g... my g7. Rh1 would be attacked by Nf3? No. Alternatively after Ke7 Ng5, I play e4 preparing Bd6/Rh8. Or h6 kicking knight? h7-h6 attacks g5 knight! Yes h6 kicks it. Good: 18...Ke7 19. Ng5 20...h6 gains tempo, knight to f3/e6... Ng5 has to move: f3, h3, e4, e6, f7. Ne6!? then Bxe6? No my bishop b7 attacks e6? b7-c6? c6 own pawn blocks. Bf1... hmm. Anyway tempo game. Or 18...Ke7 19. Nh6 gxh6 winning knight. 19. Nd6+? not check. 19. Nd8 20. ... Nf7? knight trapped on d8: attacked by? Kd7? no. d8 knight moves: f7, e6, c6(pawn), b7(bishop). Could be trapped with Ke8 later. So Ke7 seems good. But wait, does White have check after Ke7? White pieces: Bf1 (f1-a6 diagonal: e2,d3,c4,b5,a6 — no check), Rh1 (h-file open! h1 to h8 — h7 my pawn blocks at... h-file: h1, h2 empty? White pawns g2,h2 present. So no). No checks. Good. Alternatively Kc7 avoids knight tricks but loses tempo. I'll play Ke7. Actually also consider Ke8? Then knight Nxd6+? from f7 to d6 is not adjacent to e8... d6 attacks e8 yes check. Meh. Ke7 it is.

White is up 6 material. Knight on f7 attacked by... king on e7 attacks f7? King e7 is adjacent to f7? e7 and f7 are adjacent, yes. So knight is attacked by king. Also Bb7 attacks f7? Bb7 diagonal b7-c6... c6 is own pawn. No. Knight must move or be defended. Options: Nxe5 grabs a pawn — attacked by Bf8? Bf8 attacks e7, d6... not e5. Nxe5 attacks... but after Nxe5 black plays Bxe5? Bf8 doesn't attack e5. Knight on e5 attacked by nothing? Ke7 attacks... e7 adjacent squares: d8,d7,d6,e8,e6,f8,f7,f6 — not e5. So Nxe5 wins a pawn safely? Black could... Bf8 doesn't reach e5. Nd8? no knight. So Nxe5 wins pawn and attacks Bf8 and g6... also attacks c6 pawn? Knight on e5 attacks c6, c4, d3, f3, g4, g6, f7, d7. Attacks c6 pawn and Bf8? No — e5 knight attacks: d7, f7, g6, g4, f3, d3, c4, c6. Attacks c6 pawn. After Nxe5, black can play Bxg2? Bb7... g2 not reachable. Black has Bf8, bishop f8 — could take? No. Black could play Kd7 attacking knight? Kd7 doesn't attack e5. Actually Kd6? Ke7-d6 then knight attacked by king and... knight defended by nothing. But black king moving to d6 allows... knight escapes with capture. Also Bf8-g7 covers... Let me just check Nxe5 is safe: attackers of e5: none. Good. Alternatively Nh6 retreat keeps tempo but Nxe5 wins material and keeps up. Also Bd3 planning. Best: Nxe5.

Position: Black to move, down material massively. White knight on e5, White threatens? Black pieces: Ke7, Bf8, Bb7, pawns g7 h7 b6 c6. Legal moves listed: Ba8, Bc8, Ba6, Kd8, Ke8, Kf6, Ke6, Kd6, g6, g5, h6, h5, b5, c5. Knight e5 is trapped-ish? Can we attack it? Ba6 attacks e5? Ba6 from b7 to a6 — a6 doesn't attack e5. Bishop b7 to a6 moves away. Knight e5 can be attacked by... f6 pawn push attacks knight? f7 pawn is gone. g6/g5 don't hit e5. King to f6 attacks e5 — but knight could move to g4 or d3 etc. Actually knight e5 attacked by Kf6: knight can go to d3, g4, g6, f7, d7, c6 (captured pawn c6? c6 is black pawn, Nxc6). King on f6, knight moves to g4 hitting... Actually check Ba6 threatens? Ba6 attacks c4... nothing. Wait — can we trap the knight? Knight on e5: escape squares d3, c4, g4, g6, f7, d7, c6. With king f6 attacking it. If Kf6, knight can still escape via d3, g4, g6, c4 (c4 attacked by? nothing). Hmm, g4 then Bf1... White Bf1 controls g2. Knight g4 attacked by Bf1? No, f1-h3 diagonal: g2, h3. Not g4. What's the best plan? Down 7 pawns' worth, lost position probably. Maybe try to win knight or just play on. Kf6 attacks knight AND threatens? Knight escapes with tempo maybe. Alternatively Ba6 offers trade? White won't trade. Check Kf6: is it legal? e7-f6, f6 not attacked. White Bf1 doesn't cover f6. Rh1 on h-file. Knight e5 defended by Bf1? Bf1 on f1; e5 on f1-h3? No, f1 to e5 isn't a line. f1-e2-d3-c4-b5-a6 diagonal; f1-g2-h3. So knight undefended! Kf6 attacks it, knight must move: possible squares all attacked? Nc6 captures pawn c6 — attacked by? b-pawn? b6 black pawn... c6 pawn gone? c6 is black pawn still there. Nxc6 attacks? Kf6 defends c6? No, f6 doesn't defend c6. Nxc6 then Nxa... wait Nxc6 attacks b... knight on c6 attacks a5, b4, d4, e5, e7, a7, b8, d8. Then Bb6? Wait we have pawn b6. Nxc6 attacked by pawn? b6 black pawn attacks a5 and c5 — no. So Nxc6 works, knight escapes. Nd7 then Bb4+? Knight d7, Bb7... hmm. Better: after Kf6, knight best Nc6 (wins pawn? no, c6 is Black's own pawn — Nxc6 captures Black's pawn! c6 is lowercase). Oh right, c6 is black pawn. Nxc6 would be White capturing our pawn. Hmm, White pawns a2 b2 c2 f2 g2 h2; black pawns b6 c6 g7 h7. So c6 is ours. So knight e5 attacked by Kf6: escape squares d3, c4, g4, g6, f7, d7 (c6 occupied by own pawn). Nc4 attacked by? b2? No. Nd3? Nothing attacks d3. Ng4? Bf1 doesn't attack g4; h-pawn? g2? No. So knight just escapes. Alternatively is there a tactic? White pieces: Kc1, Rh1, Bf1, Ne5. Black: Ke7, Bf8, Bb7, pawns b6 c6 g7 h7. Any checks? Ba6 no check. Kd8? No. Could try to harass knight with Bb7-a6? No. Honestly best move might be Ke6 offering to trap knight: Ke6 attacks e5 too, and covers d7, f7... Knight escapes: Nc4 (not attacked), Ng4? Ke6 covers f7, d7. Nc4 free. Then Nxa? Hmm. Kf6 also covers g6 and f7, leaving d3, c4, g4. Ng4? then h2-h3 or Bf1... g4 attacked by nothing; knight g4 attacks f2, e3, h2, e5, f6, h6 — forks? attacks h2 pawn and f2 pawn. Then hxg? h3 kicks it, Ng... e5/e3. Meh. Maybe simply play Ke6? Or actually consider g6 to solidify. With huge material deficit, best practical: Kf6 hitting knight, forcing it to commit. If Nd3, then Bb... nothing. Also consider trading: after Kf6, if Nc4, then Bf8 could go... Bc5? pinning? Bc5 attacks? Not much. Also check Kd6: attacks e5? d6 adjacent to e5 yes. Covers c5, d7? covers e7,c7. Knight escapes Nc4/Nd3/Ng4/Nf7 (f7 attacked by Kd6? no, d6 covers e7, e5, c5... not f7). So Kf6 better. I'll play Kf6. Quip: something about security deposit.

Position: White up a rook+ (up 7 material). Black king on f6 is exposed. Best move? Nd7+ forks king... check. Let's think. Nd7+ K moves (Ke7 or Kf5... king on f6, Nd7 checks). After Nd7+ Ke7, knight could be trapped? Nd7+ then king attacks? Ke7 attacks d7 knight? No, e7 adjacent to d7? Yes e7 is adjacent to d7 diagonally? d7-e7 adjacent horizontally. Knight on d7 attacked by king on e7. But defended? Not defended. Knight can move away or Nf6+? Hmm. Nxc6 Bxc6 wins a pawn but trades knight. Ng4+ check: Ng4+ Kf5 then? Knight on g4 attacked by king f5. Not good. Nd7+ Ke7, then Nf8? Nxf8 wins bishop? Nd7+ Ke7, knight attacked; Nf6? gxf6. Nf8 Kxf8 loses knight for bishop. Actually Nf8 Kxf8 - trade knight for bishop, bad-ish but we're winning anyway. Hmm, Nd7+ Ke7, Nf6!? gxf6 then Bxb6 wins pawn? Then bishop takes b6... net: knight for pawn + bishop for bishop... loses. Better: Nxc6! forks? c6 pawn defended by Bf8? No, f8 bishop doesn't defend c6 (b7-a8 diag... f8 to c5). Bb7 defends c6. Nxc6 Bxc6 loses knight for pawn. Bad. Nd3 or Nc4 keeps knight safe. What about Ng6: attacks h8? Nothing there. Ng6+ is not check? King f6, Ng6 — no check. Actually knight on g6 gives check to f6? Knight attacks f4, h4, e5, e7, f8, h8 — not f6. Not check. Nd7+ Ke7 then Nf8!? Kxf8 no. Alternatively Nd7+ Kf5 then Ng... no, Kf5 attacks g4 not d7. Nd7+ Ke7, what about Bxb6? Then knight escapes next? No, king captures knight next move... after Bxb6, black plays Kxd7. So knight must move with check or safe square: Nd7+ Ke7, Nf8+!? Kxf8. Or Nd7+ Ke7, Nb8!? knight trapped corner. Hmm, maybe better: Nf7 retreat keeps... also check? Nf7 from e5: knight attacks f7 to... moving to f7 attacks d8, e5, g5, h6, h8, d6 — not check. King f6 doesn't attack f7? f6-f7 adjacent, yes attacked and undefended. Bad. What about Ng6: knight on g6 attacked by? King f6 doesn't attack g6 (adjacent yes f6-g6!). Adjacent. Attacked, defended by nothing. Bad. Nd3, Nc4, Nf3, a4, b3 — consolidate. Nd3 keeps knight active, targets c5/b4/e5. Actually Nd7+ Ke7 then Nb6!? knight attacked by...Nb6 attacks c8, d7, a8, d5, c4, a4. Attacked by pawn c6? c6 doesn't attack b6. King e7 doesn't. Safe! And forking? Nb6 attacks... d7, c8, a8, d5, c4, a4 — c6 pawn? No. Hmm Nb6 attacks d5, c4 — no black pieces. But safe and central. Also Nd7+ Ke7, Nf8+ Kxf8 — knight for bishop f8? No wait Nf8 gives check (f8 attacks e6, d7, g6, h7... wait knight on f8 attacks e6, g6, h7, d7, d9). Kf7 adjacent to f8. Does Nf8 give check to Ke7? Knight f8 attacks d7, e6, g6, h7 — not e7. Not check. So Kxf8. Nd7+ Ke7 Nb6 then Bxb6? Bishop b7 can take b6! Bxb6. Hmm, then axb6? a2 pawn can't reach... a-pawn can't. So Nd7+ Ke7 Nb6 Bxb6 loses knight. Nd7+ Ke7, Nf6!? gxf6. Bad. Nd7+ Ke7, Ne5+?? back, no. Alternative after Nd7+ Kf5: then knight safe on d7? Kf5 doesn't attack d7. Then continue Bxb6 winning pawn? Nd7+ Kf5, Bxb6 axb6? a-pawn captured earlier, b6 pawn captured by... wait Black has b6 pawn? Black pieces: b6, c6 pawns. White a2 pawn: Bxb6 axb6?? a-file has no black pawn (a-pawn captured b6 bishop earlier? Move 17... axb6 captured white bishop — black a-pawn moved to b6, then... wait Black pawns now b6 and c6. b6 is the original a-pawn? 5... bxc6, so b-pawn went to c6. a-pawn: 17...axb6 captured bishop on b6. Then 18. Nf7+... a-pawn on b6 now. And 5...bxc6 put b-pawn on c6. So Black's b6 pawn is the a-pawn, c6 pawn is the b-pawn. So Bxb6 axb6 impossible — no a-pawn. Bxb6 wins clean pawn. So Nd7+ Kf5 Bxb6 wins pawn, knight safe on d7? Kf5... then black plays... bishop c8 or something. Then White can follow with Nf... Actually also after Nd7+ Kf5, g6!? then Bxb6 wins pawn. But wait — does Nd7+ Kf5 threaten king marching? Kf5 then Ke4? White should be careful with exposed king. After Nd7+ Kf5, Bxb6 then Kg4 attacks h2? Eventually. White king c1 is safe-ish. Black king invasion: Kf5-e4 possible. White should maybe advance too. Alternative: quiet strong move: b3/Bd3 developing. But check first is good: Nd7+ forces king response. If Ke7, knight escapes via... after Nd7+ Ke7, knight is attacked. Options: Nc5!? attacked by b6 pawn? b6 attacks c5? Pawn on b6 attacks a5 and c5. Yes. Nd7+ Ke7 Nc5 bxc5. Bad. Nd7+ Ke7 Nb8 attacked by? nothing, but trapped: corner, a6? Nb8-a6-c4... can escape via a6? King can't catch quickly. Nb8 then Na6 then Nc4/Nc5. Actually Nb8, then black Bc8 attacks b7... bishop f8. Nb8 fine probably. Nd7+ Ke7 Nf8!? no. Nd7+ Ke7 Nb8 seems safe escape: b8 not attacked. Then Na6 hits c7... nothing there, then Nc5!? bxc5 — hmm knight gets harassed. Actually simpler: don't fork, just play Nf3 retreating to safety, keeping extra pieces, then Bd3 etc. But winning more material is better. What about Nd7+ Ke7 and then Bxb6!? Kxd7 loses bishop trade... no, Bxb6 Kxd7 loses knight for pawn+bishop? White: knight lost, gained b6 pawn; black gains knight. Net White down knight vs pawn... no wait: Bxb6 (wins pawn), Kxd7 (wins knight). Bad. Nd7+ Ke7 Nb8 then axb6?? no a-pawn... Black can't take. Nb8 is safe. Good. Or Nd7+ Ke7, Nb6 Bxb6 — bad as shown. So Nd7+ followed by Nb8 if Ke7, or Bxb6 if Kf5. Wait also after Nd7+ Kf5, is there Nf... hmm, also after Nd7+ Kf5, knight d7 forks? attacks b8, f8, c5, e5. Bf8 undefended? Nxf8? d7 to f8: yes! Nd7+ Kf5 Nxf8 wins bishop? Wait bishop on f8, knight d7 attacks f8. Is f8 defended? By Bb7? b7-f... b7 defends f3 diag and a8-h1? b7 diagonal: a8, c8, d5, e4, f3, g2. Not f8. King far. So Nd7+ Kf5, Nxf8 wins a clean bishop! But wait, why would black allow — after Nd7+ Kf5, then Nxf8 wins bishop. But knight on f8 then... trapped? Nxf8, then black can... king f5 can't reach f8 quickly; bishop b7 can't. Knight escapes via g6/d7/e6. e6 attacked by king f5? e6 adjacent to f5 — yes. Knight f8 to g6 or d7. Black king could approach but takes many moves. So Nd7+ Kf5 Nxf8 wins bishop. And if Nd7+ Ke7, knight attacked; escape squares: Nb8, Nf6!? (gxf6 no pawn g7 yes gxf6). Nb8 safe. Then White up a whole rook+... material currently +7, after Nb8 still +7. Fine. Alternatively consider Ng4+ Kf5 then Nf2/Nh6/Nxh... Ng4+ Kf5, knight attacked by king, retreat Nh6+!? Kf6... nothing gained. I think Nd7+ is the strong move. Actually wait — is there something even stronger? Ng6?? attacked. What about Nd7+ vs Nf7-c5 patterns... Nd7+ best. Hmm, but consider: does Nd7+ allow Ke7 hitting knight where Nb8 is only escape — Black could then play Bc8! attacking b7... after Nd7+ Ke7 Nb8, black plays c5!? then bishop... c5 attacks b4/d4, knight b8... Nb8 escape via a6: Na6 then Nc5 or Nc7. Black bishop b7 could hit a6? b7-c8... no, b7 attacks a6? Yes! b7 diagonal to a6. Hmm. Na6 attacked by Bb7. So Nb8, Na6 Bxa6 loses knight for bishop — trade knight for bishop is roughly fine material-wise but White shouldn't trade down... Actually up a rook, trades are fine. But knight could go Nb8-c6!? attacked by Bb7... b7-c6 yes. Nb8-a6 Bxa6 (trade N for B, fine). Or Nb8-c6? Bxc6 anyway. Knight may be somewhat trapped but can trade for bishop or escape via d7->... Alternatively after Ke7 don't retreat: Nd7+ Ke7 then Nf8!? Kxf8 loses N for B, equal trade fine. Even simplest: Nd7+ Ke7 Nb8 and if Bc8 then Na6!? Bxa6... hmm equal trade. Or Nb8 then c5, then Na6 Bxa6 Rxa6?? no rook on a-file... Rh1. Hmm. Alternatively, quieter safe plan: Nf3, Bd3, connect rook... knight to e5/d4 dominating. Also strong and safe. But Nd7+ forces matters and wins at least a tempo; worst case knight trades for bishop (fine when up rook). Actually let me recheck: after Nd7+ Kf5, is Kf5 legal? King f6 to f5: attacked by? Nd7 attacks f8,f6? Knight d7 attacks b8, b6, c5, e5, f6, f8. f6 — vacated. White pieces attacking f5? No. Legal. Then Nxf8. Good. After Nd7+ Ke7 (e7 attacked? by Bd3? no bishop f1. By Nd7 attacks e5,f6... not e7. King can step to e7? e7 attacked by knight? No. Legal.) Then Nb8. I'll play Nd7+ with a quip.

Position: Black to move, in check from Nd7. King f6. Moves: Ke7, Kf7, Kg6, Kg5, Kf5, Ke6. Wait — Ke6 attacked by nothing? Nd7 doesn't attack e6. Bf1 attacks... f1 bishop: diagonal e2-g3-h4, blocked. Rh1 on h-file. So Ke6, Kf5, Kg5 possible if not in check. White threatens Nd7xf8 winning bishop, or Ne5/Nc5. Also Nb8 attacks? Let's check: after Ke6, knight must move; Nd7 attacks f8. White can play Nxf8 winning a bishop. Then Black Kxe5? Actually after Ke6, Black threatens Kxe5 nothing... e5 is empty? Black king at e6. White knight d7 could be captured by... Bb7xc6 no. Bb7 attacks d5, a6, c8, etc. Can anything take d7? No. White down material is 17 vs 10 (White winning). Black must avoid losing more. If Ke6, White plays Nxf8 and Black king chases knight? Nxf8 then knight at f8, Black king e6 can't catch h7/g7? Knight escapes via g6 or d7... Actually knight f8 can go h7, g6, e6 (check), d7. Kf7 traps it? After Ke6 Nxf8, Black could... knight still free eventually. Alternative: Kg6. Then knight d7 is attacked by nothing; knight can go Nxf8 or Nb8. Hmm. Can Black trap the knight? After Kf7?? knight can't move... no, Kf7 leaves check? Nd7 attacks f8, b8, c5, b6, e5, f6, f7? Knight on d7 attacks: b8, f8, b6, f6, c5, e5. Not f7. Kf7 legal — then knight is attacked? Kf7 attacks e8, f8, e6, g6, etc. Knight d7 not attacked. But knight moves Nf8 check? No, f8 occupied by Black bishop. Knight attacked by king f7? d7 not adjacent to f7. Knight could be trapped: Kf7, knight must escape via b8/c5/e5... e5 attacked by Kf7? No, f7 adjacent to e6, e8, f8, g8, g7, g6, e7... e5 not adjacent. Threats to White: Black bishop f8 and b7, pawns. White king c1 exposed? Rh1, Bf1 back rank: Kb1... White's king somewhat loose but Black has few attackers. Black is losing badly (down queen/rooks). Best practical: try to trap or win knight. After Kf7, knight must move; where? Ne5+ fork? e5 attacked by f7? Knight can go Ne5+ checking king f7, then Nxc6/Nxf7... After Kf7 Ne5+ Ke7? Then knight attacked by Ke7? e5 adjacent to e7? No. Hmm. Actually Kf7! knight's only squares: b8, c5, e5(+check), f8(occupied), b6(occupied by own pawn... b6 is black pawn), f6 vacated. So Ne5+ Ke7/Kd6/Kd8/Kc7... Ne5+ Ke7 attacks e5. Knight goes Ng4/Nc4/Nf3 etc. Black gains tempo but knight escapes. Kg6!? then knight takes f8 Nxf8, Black king g6... then Kh7! traps knight f8? Kh7 attacks g8, f8? No — h7 adjacent to g8, g7, g6, h6, h8. Not f8. Hmm, knight f8 after Kh7 can go... e6, d7, g6(check?), h7!? Knight f8 attacks h7! Nxf8 Kh7?? Nh7 no — knight on f8 attacked by king? f8-h7 not adjacent. Knight f8 attacks g6, h7, e6, d7, g8... wait knight f8 moves: d7, e6, g6, h7, and that's it (b/c off board or occupied? f8: e6, d7, g6, h7). Nxf8 then Kh7! attacks... knight is at f8; Kh7 doesn't attack f8. But knight moves to h7 would be illegal (king there). Knight's escape squares: e6, d7, g6(check to Kh7! g6 adjacent to h7 — knight check, then king captures g6? king can capture knight on g6 if unprotected — yes). So Nxf8 Kh7 Ne6?? wait Ne6 check? e6 knight checks h8... no check. Knight e6 attacked by Kh7? No. Hmm, knight escapes anyway. Realistically the knight will escape; Black just down material. Best move maybe Kf7 attacking towards knight, or Ke6 heading to e5 target. Actually a key idea: Ke6! then if Nxf8, Kxe5?? no. Hmm, Ke6 eyes e5 and f5... If Ke6, White might play Nc5/Nb8/Nxf8. Then Black Bxg2 idea: Bf8xg2 attacking Rh1? Bf8-g7? No, g7 has own pawn. Alternative plan: Black bishop pair vs knight+rook+bishop+5 pawns. Black 10 vs 17 — hopeless-ish but play on. Check for tactics: Bf8 vs Rh1? Nothing immediate. Black bishop b7 aims at g2 (through c6 own pawn). If c5 pawn advance? Black has b6, c6, g7, h7. Move candidate: Ke7, keep bishop f8 guarded... Nd7xf8? f8 bishop defended by? Nothing (g7 pawn doesn't defend f8; king e7 defends f8). So Ke7 prevents Nxf8. Then knight must retreat: Nc5/Nb8/Nb6/Nf6? Nf6 attacked by Ke7? No, f6 adjacent to e7? e7 adjacent squares: d6,d7,d8,e6,e8,f6,f7,f8 — yes f6 adjacent, so Nf6?? Kxf6. Knight must go b8, c5, b6(pawn), e5. Ne5? attacked by Ke7? e5 not adjacent to e7. Ne5 then... Kd6? Hmm. Ke7 seems solid: prevents Nxf8, keeps material. But knight Ne5 then threatens? Not much. Also White might play c4, Kb1, Rhf1 etc. Also consider Ke6 allowing Nxf8, then Black gets ...Kxe5 later? No. Alternatively Kf7 threatening? Nothing; knight Ne5+ Kf6 back? Actually Kf7 Ne5+ Ke7 same as before. Also Kg6!? aiming to support ...h5, ...g5? Meh. I think Ke7 is best, keeping the bishop. Then knight likely Ne5, and Black can consider ...Kd6 attacking e5 knight? Kd6 attacks e5, c5, d7! Then knight must move. Chase it a bit. Also there might be a tactic: after Ke7, if knight goes Nb6, axb6? No a-pawn... b6 is black pawn. Nc5!? attacked by b6? No. Nc5 attacked by... nothing. Then b6xc5?? pawn b6 captures c5? No, b6 pawn captures on a5/c5 — yes! bxc5 wins knight? b6 pawn moves toward... Black pawns move down (toward rank 1). b6 captures on a5 or c5. So Nc5?? bxc5! wins knight. Good — so knight's safe squares after Ke7: e5, b8, d7-stay? Actually White must move knight (it's checking? No — knight on d7 doesn't give check; Black to move was in check... wait Black is in check from Nd7? Knight d7 attacks f6 yes. So Black must move king. After Ke7, White to move; knight can stay d7? White could play Nc5 (loses to bxc5), Nb6 (attacked by? c-pawn? c6 captures b5/a5... c6 pawn captures on b5 or d5, not b6), Ne5, Nb8, Nxf8(illegal now? f8 defended by Ke7 — Nxf8 Kxf8). So Ke7, and White's best Ne5 or Nb8. Ne5 then Black ...Kd6? No wait knight e5, Kd6 attacks it. Knight goes f7? f7 attacked by Kd6? No. Nf7 then heading to g5/h6... but Bf8? Also White could push g4 etc. Also Black wants to activate: ...Bc5 ideas? Bf8-b4/c5 later, Bd6 pinning? Bd6 vs Bf1? Bishop d6, White Bf1, Rh1. ...Bc5+ Kb1, ...Bb4 pressuring c3? No pawns c3. Fine, play 20...Ke7. Quip: something about escaping to a safer apartment, knight's rent-free days numbered. Actually double-check Ke7 legality: e7 attacked by anything? Nd7 attacks f8, f6, b8, b6, c5, e5 — not e7. Rh1 no. Bf1 no. Ke7 legal.

The knight's fork threat f8 is real, but Ke7 covers that square — my bishop stays put, and now his wandering knight has nowhere safe to jump (Nc5?? bxc5, Nf6?? Kxf6).

Cute fork, but I've parked the king on e7 — your knight's eviction notice is already drafted.

GLM 5.3 High· move 21

Knight on d7 attacks f8 bishop and b6 pawn. Nxf8 wins bishop, but after... actually Nxf8 Kxf8 just trades knight for bishop. Better: knight attacks f8 bishop. Black bishop is trapped? Bishop on f8 can go g7? g7 is occupied by pawn... wait, g7 pawn is Black's own. Bf8 can move to... it's blocked by g7 pawn and e7 king? Diagonals: g7 (own pawn), e7 (own king). So bishop is trapped! Nxf8 just wins the bishop since Kxf8 possible... Kxf8 recaptures — knight for bishop trade, equal material exchange, but we're up material. Wait, is Kxf8 legal? King on e7, f8 adjacent, yes. So Nxf8 Kxf8 trades N for B. Fine but not winning the piece. Alternative: Nxb6 wins pawn — cxb6? c6 pawn can capture b6? c6 captures to b5, not b6. Pawn on c6 captures b5 or d5. So Nxb6 attacks... Nxb6 hits the bishop? No. Nxb6 forks? From b6, knight attacks d5, c8, a8, d7, c4, a4. Wins a pawn safely? Bishop b7 can take? Bb7 attacks... b7-c8? No, b7 diagonal to a8 and c8 (empty), and a6, c6 pawn own... So Bxb6 impossible. So Nxb6 wins a clean pawn. But better: Nxf8 then Kxf8, then we're up 7 (R each... wait). Actually, can we win the bishop outright? Bishop f8 trapped. If we move so that Kxf8 isn't possible or costly... Knight is on d7 attacking f8. If we don't take, bishop stays trapped. Play a quiet move keeping knight there, e.g., Bc4!? threatening... Actually knight on d7 attacks f8. Bishop has no moves. If we play another move, Black must move something else; bishop stays trapped forever until g-pawn... g7 pawn can't move (g6/g5 blocked by... g6 empty, so g7-g6 possible, opening g7... no, pawn moves to g6 doesn't free f8 bishop; after g6, bishop can go... f8 diagonal g7 now empty! So g6 frees bishop via Bg7. Hmm, g6 then Bg7 escapes? Bg7 then attacked by nothing. So Black can free it with g6. So taking now: Nxf8 Kxf8, trade N for B, net material stays +7 (N and B equal). Or keep knight and Black plays g6, saving bishop. Alternatively Nxb6 wins pawn while bishop still trapped? After Nxb6 g6, bishop escapes anyway. Hmm. Best: Nxf8 Kxf8 — simplifies, we're up 7 pawns worth (actually up queen+2 rooks+2 knights+4 pawns minus... material 17 vs 10, difference 7). Trading N for B keeps 17-... 17-3=14, 10-3=7, still +7. But endgame simplification with huge material advantage is good. Alternatively, Nxb6 wins pawn: 18-... wait White 17 +1 pawn =18? Nxb6 takes pawn: White 18, Black 10? No — captures change count. White captures pawn: White pieces = 17+1=18, Black loses 1: 9? Black 10, loses pawn → 9. So 18 vs 9, +9, but Black then g6 saves bishop and can play axb6? No a-pawn. After Nxb6, bishop b7 trapped too? Bb7 diagonal: a8, c8, a6, c6 (own pawn). Trapped-ish. Black could ...g6 then Bg7, then bishop f8 escapes to g7? Only one bishop at a time. Hmm. Actually strongest might be Nxb6 g6 Bg7... let's think. Nxb6 threatens nothing else. Black plays g6 intending Bg7. Then Bf8 still trapped until g7 vacated... g7 pawn moved to g6, so f8 bishop can go g7. So Black saves one bishop. Which one? Bg7 from f8, then Bb7 still stuck. Or Black plays ...g6, ...Bg7 saves the f8 bishop. Then White could take a8? No knight on b6 attacks c8, a8 — nothing there. Alternatively Nxf8 first: wins bishop immediately via trade? That's just a trade. Hmm, but wait — can Black not recapture? Kxf8. Yes. Alternatively Bd3 or Bc4 developing, keeping both threats: knight attacks f8 (trapped bishop) and keep tension. If Black plays g6, then Nxf8! now Kxf8 and bishop g7 exists? After g6, Nxf8 Kxf8 wins bishop for knight, but Black then has Bg7 developing the other... no wait, after g6 the f8 bishop could flee to g7. So before g6, f8 bishop is trapped; the threat of Nxf8 isn't a win since recapture. But actually the trapped bishop means Black loses a tempo problem. The point: if Black plays g6 (freeing), we respond Nxf8+? Kxf8 — still just a trade. Alternatively after g6, bishop on f8 can move to g7, so we should capture before. Either way it's N for B trade. Hmm, is there something better? White up 7 (basically up rook + 7?). Material: White has R, B, N, 7... let's count: Rook h1, bishop f1, knight d7, pawns a2,b2,c2,f2,g2,h2 = 3+3+1+6 = wait R=5, B=3, N=3, 6 pawns = 5+3+3+6 = 17. ✓. Black: Bf8, Bb7, Ke7, pawns b6, c6, g7, h7 = 3+3+4=10. So White is up a full rook (5) plus... 7 points ≈ rook + 2 pawns. Simplest winning plan: trade pieces, push pawns. Nxf8 Kxf8 leaves R+2B+6P vs B+4P → up 11-7? White: 5+6+6=17-3(N)=14; Black 10-3=7. Wait White loses knight (3): 14, Black loses bishop (3): 7. Up 7 still, now rook + 2 bishops... R+B+6P vs B+4P: White 5+3+6=14, Black 3+4=7. Yes. Actually can we win the f8 bishop for free? Nf6+! gxf6 — no, Nf6 forks? From f6 knight attacks e8, d7, g8, h7, h5, g4, e4, d5. That's gxf6? g7 pawn captures f6. Knight attacked by g7 pawn and king? King e7 doesn't attack f6. Nf6 gxf6 loses knight for pawn. Bad. Nc5 attacks b7 bishop! Nc5 forks b7 bishop and... from c5: b7, a6, d7, e6, e4, d3, a4, b3. Attacks b7. Bishop b7 moves: a6? then Nxa6? No wait, bishop escapes to a6 or c8, a8? Bb7 diagonals: a8, c8 (a6 too but Nc5 attacks a6... does knight on c5 attack a6? Yes). So Bb7 can go a8, c8, or... c8, a8 not attacked by knight. Then Black also frees with g6 later. Nc5 wins nothing immediate. Best plan: Nxf8 simplification? Or keep knights and win pawns. Nxb6 wins a clean pawn (c6 pawn can't recapture, bishop can't). Then threat: bishop f8 still trapped, Black plays g6 Bg7 saving it. Net: win a pawn, and maybe bishop b7 trapped? After Nxb6, Black ...g6, ...Bg7, ...a6? no a-pawn. Bb7 can escape via c8-d... c8 then d7... blocked? After g6, Bg7, then Bc8 possible? e7 king... Bb7 to c8 to d7? d7 empty after knight moved. So both bishops survive eventually. Alternatively Nxf8 Kxf8 then win b6/c6 pawns with bishop? Position after: White Bf1, Rh1, 6P vs Black Bb7, 4P. Then Bd3 attacks b6? No, Bd3 hits... b5 pawn? Black pawns b6, c6 block. Still winning easily (up rook and 2 pawns with R vs B). Or even better: after Nxb6, bishop f8 is STILL trapped (needs g6 tempo). And knight on b6 attacks c8/a8 preventing Bb7's escape to those squares? Bb7 escapes to a8/c8 — knight on b6 attacks a8 and c8! So after Nxb6, BOTH bishops are trapped! Bishop b7: a8 (Nxb6 attacks), c8 (attacked), a6 (attacked by knight? b6 knight attacks a8, c8, d7, d5, c4, a4 — not a6). So Bb7→a6 escapes. Hmm. But a6: then White... bishop f1 could take? No. Knight on b6 attacks a4, c4, not a6. So Ba6 escapes one square. Then Nc4? attacks a5, b... c4 knight attacks a5, b6, d6, e5, e3, d2, b2 — attacks... a5 and b... not a6. Alternatively Nxf8 wins a whole bishop via trade, Nxb6 wins a whole pawn and keeps knight attacking c8/a8. Trade N (3) for B (3) = neutral exchange. Pawn win = +1. Hmm what about Nxb6 followed by g6? Then Black threatens Bg7 saving f8 bishop. White plays Nd5? or Nc4 hitting a... Let me not overcomplicate. Actually — what about Nxb6 and if ...g6, then Nc8+!? Knight b6 to c8/d7/a8... Nc8+ forks? From c8: e7 king (check!), a7, b6, d6, e... check to e7. Then Bxc8?? no bishop can't. King moves, then knight on c8 attacks b7 bishop! Fork: Nc8+ Ke8/Kd7/Kf8... king e7 in check from c8, moves, then Nxb7 wins bishop. But wait bishop f8 — after g6, bishop could also defend. Let's see: Nxb6 g6, Nc8+ Kd8 (or Ke8, Kf8?? f8 occupied by bishop... king on e7, f8 has bishop; squares: d8, e8, d6, f6). If Kf6?? then... whatever, Nxb7 wins bishop. Also Nc8 attacks a7? Yes but empty. So Nxb6 g6 Nc8+ K~ Nxb7 wins a bishop AND knight escapes? Knight on b7 after capture, attacked by... nothing much. Black recaptures? King far. So Nxb6 wins pawn + bishop (knight survives). That's +4! But careful: Nxb6 g6, is Nc8 check legal/safe? Nc8 attacked by Bf8? Bf8 attacks g7, e7 — not c8. Bb7 attacks c8! Bb7xc8. Oops! Nc8+ Bxc8 loses knight. Bad. Alternative: Nxb6 g6 then Bd3 or so. Let's just evaluate simple: Nxb6 wins a clean pawn and keeps enormous advantage. Black's best then ...g6 saving f8 bishop, but Bb7 remains semi-trapped (only a6). Then Bd3 maybe or a4-a5 ideas. Compare Nxf8 Kxf8: up rook+2, R+B vs B... very trivially winning too, with rook vs bishop and 6 vs 4 pawns. Honestly Nxb6 might be cleaner: keeps knight, wins pawn, both bishops awkward. Or even stronger: does Black have real counterplay? Black's bishops passive, king e7 exposed-ish. White winning easily either way. Actually, let's check Nxf8 more: after Nxf8 Kxf8, White has R, B vs B and 6v4 pawns — completely winning, up rook essentially. That's simplest. But it returns a piece. Nxb6 keeps all material edge. Another idea: a4 (or any waiting move) keeping threat Nxf8? If Black plays g6, then Nxf8 Kxf8... still trade. If Black plays something else, Nxf8 stays a trade. The f8 bishop can never be won cleanly since Kxf8 always recaptures. Unless we deflect: Bd3? threatening... no. What about Rg1?? doesn't help. Bc4 threatening mate? Bc4 attacks... c4-d5-e6-f7-g8: nothing. No checks available really. I'll play Nxb6, winning a pawn, with quip. Check safety: after Nxb6, is knight attacked? By c6 pawn? No (pawns capture diagonally forward: c6 captures b5/d5). King e7 doesn't attack b6. Bishop b7 attacks a6, c6(own), c8, a8 — not b6. Bishop f8 no. Safe. Black reply g6 then Bg7? Bf8 to g7 yes. Then position: White R, B, N, 6P (18... minus nothing) vs Black 2B... wait after Nxb6 Black lost pawn: Black has 9. White up 9. And Black's b7 bishop can go Ba6. Then White maybe a4-a5? Or just consolidate. Totally winning. Alternatively even stronger after Nxb6 g6: Nd5! attacking f6? knight d5 attacked by... c6 pawn! c6xd5. No. Fine, Nxb6.

Looking at this position, I see Black's f8-bishop is nearly trapped (blocked by king and its own g7-pawn), and the b6 pawn is hanging — the c6-pawn can't recapture diagonally to b6, and neither bishop covers that square. Grabbing the pawn while keeping both enemy bishops breathing through a keyhole seems cleanest.

GLM 5.3 Flash High· move 21…

Position: Black king e7, bishops f8 and b7, pawn c6, g7, h7. White: Kc1, Rh1, Bf1, Nb6, pawns a2,b2,c2,f2,g2,h2. White knight on b6 is strong. Black is down 8. Need to do something. Knight on b6 attacks... nothing much; it could go to a4, d7 fork? White threats: Nc8? Nd7+ hitting Kf8... Actually knight b6 can fork: Nd5+? No, from b6, moves: Na4, Nc4, Nd5+, Nd7, Nc8, a8? Knight on b6: a4, c4, d5, d7, c8, a8. Nd7 forks nothing immediately? Nd7 hits f8 bishop and c5... Nd7 attacks Bf8, Bb7? No, d7 attacks b8, f8, f6, c5, e5, b6. So Nd7 attacks Bf8. Kd7? King is e7, can capture? King on e7 can't capture d7... wait knight on d7 would be adjacent to e7 king, so Kxd7. Threat: Nc8 forking? c8 attacks a7, b6, d6, e7? No, c8 attacks e7! Knight c8 attacks a7, b6, d6, e7 — yes fork of... just king and Rook? Not a fork. Hmm. Black options: Bc8 pinning knight against? Bc8 attacks b7... own bishop. No, Bc8 attacked by knight b6. Not good. Position: Black material down but can try to win pawns. Bb7 attacks b2 pawn? b7 bishop diagonal: a8, c8... toward h1: c6 own pawn blocks. Ba6 attacks b2? No. Threats: Nd5+ then... Kd6/Kf6. Also Rh1 rook. Maybe best: g6/g5 to activate bishop, or Kd6 to attack knight? Kd6 attacks b6? No, d6 to b6 not adjacent. Kf6? Ke6, Kd6. Actually, threat from White: Nd7+ then knight escapes and forks? Or Nc8 hitting Ke7 — king must move, then knight takes... nothing. Nd5+ Ke8, Nxc... hmm. Best idea: attack the knight with c5! c6-c5 doesn't attack b6. Ba6? From b7... wait Black bishops: Bb7 and Bf8. Ba6 from b7: bishop b7 to a6, attacks... knight b6? No, a6 doesn't attack b6 (diagonal a6-b7). Kd8? Bishop f8 moves: Ba8? No, f8 to a8 blocked by b7? f8-a3 diagonal: e7 (own king). Can't. Bc8? No that's from b7? Bb7 to c8 attacks b6? No. Actually can Black trap the knight? Knight b6 escape squares: a4, c4, d5, d7, c8, a8. Ba8 from... f8? f8-a8 along 8th rank: e8, d8, c8 empty, yes! Ba8 — wait f8 to a8 passes e8, d8, c8 all empty. So Ba8 is legal (f8-a8? that's not diagonal... f8 and a8: f-e-d-c-b-a on rank 8 — that's a straight line, bishops move diagonally!). Ba8 from f8 is illegal... but legal moves list includes Ba8. From b7? b7 to a8 is diagonal, yes. So Bb7-a8. Then knight can't go a8 or c8. But other escapes exist. Hmm, Kd6 attacks knight? King d6 attacks c5,c6,c7,d5,d7,e5,e6,e7 — not b6. Kc5 impossible (own pawn c6 blocks... c5 is empty, pawn on c6). Kc6? blocked by own pawn. Can anything attack b6? Ba6 from b7! Then bishop a6 attacks b6? No — a6 to b7 diagonal; knight on b6 is not on a6's diagonals (a6 diagonals: b5, b7, c4...). No. Trap idea: Bc8 controls a6? Not helpful. Realistic plan: down 8, just play best moves. White threats: Nd7+ forking Kf8? Nd7+ king must respond; knight attacks f8 bishop. Then Bxd7? No, after Nd7+ Kxd7?? King on e7 can take d7 knight — yes Kxd7 wins knight! But wait, is Nd7 check? Knight d7 attacks e5, f6, f8, b8, c5, b6... e7? d7 to e7 is adjacent square but knight attacks are L-shapes. Knight on d7 does NOT attack e7. So Nd7 isn't check, but attacks Bf8. Kxd7 then? King e7 to d7 — is d7 attacked by White? Rh1 no, Bf1 no (f1-e2-d3-c4-b5-a6). So Nd7 Kxd7? Wait after Nd7, Black king can capture: Ke7xd7. But then White... nothing recaptures. So Nd7 loses knight. Threat Nd5+ then Ke8, Nc7+? d5: c7+ forks? c7 attacks e8? No wait knight c7 attacks a8, e8, a6, e6, b5, d5. So Nc7+ forks Ke8 and... nothing else. Hmm. What about White Rh1 pressure? Not immediate. Black counterplay: attack b2 pawn with Ba6. Bb7-a6 attacks b5? No — a6 bishop attacks b5, c4... and b7, c8. Doesn't hit b2. Bishop f8: after king moves, Bf8 can come to c5 hitting b4? Or Be7. Simplest strong move: Kd6 attacking... nothing? Or g5/g6 to get light squares. Actually maybe better: Ke6? Or think about winning the knight. Knight b6 is stuck-ish. Can Black play Bc8 then... Bc8 attacked by knight, but it defends? If Nxc8, then... nothing recaptures. Alternative: play c5, then if Nd7 c5? Hmm. What about Kf7 heading to help? Not needed. Let me think about immediate tactics: White knight b6 threatens Nd5+ and Nc8/Nd7 winning bishop f8? Nd7 attacks Bf8 — if Black responds g6 or keeps, after Nd7, Black can play Kxd7! So that's fine. White threat: Nc4? no threat. Actually White's main plan: Na4/Nc4 then knight survives; or Bd3 pressure. Black could try g5 then Bg7 pressure h2/f2. Also Ke6/Kf7 freeing f8 bishop. But f8 bishop blocked by e7 king currently? No, e7 occupied by king — bishop f8 has moves: e7 (occupied), g7 (own pawn), so only a8? Not diagonal. Bishop f8 currently only... diagonals: e7,g7 occupied. So Bf8 is blocked. King must move to free it. Best: Kd7? attacked by anything? d7 attacked by Nb6! Knight b6 attacks d7. So not. Kf7, Ke8, Ke6, Kd6, Kd8 all legal per list. Kd6: frees e7 for bishop? Bishop f8 to e7 then. Kd6 attacks c5 pawn? There's no pawn; Black c6 pawn — Kd6 blocks own pawn. Kd6 eyes knight? No. Kf6: attacks g6? frees e7. Kf6 then Be7, then bishop e7 active. But Kf6 allows Nd7+?? Kf6 is attacked? Knight b6 attacks d7, c8, a8, a4, c4, d5 — not f6. But after Kf6, White Nd7+ forks Kf6! Knight d7 attacks f6 — yes! So Kf6 blunders to Nd7+ K moves, Nxf8. Ke6: allows Nd7+? d7 doesn't attack e6. Ke6 then Nd7+ no... wait knight d7 attacks: b8, f8, b6, f6, c5, e5. Not e6. So Ke6 safe from that. But Ke6 allows Nd5?? not check. Ke6 also allows Rh6+? Rh1-h6+ check! Rh6 pins/attacks g6... Ke6 in check from Rh6, then Kf7/Ke5?? f5? Black king e6, after Rh6+ Kf7? No that's away. Hmm, Ke6 exposed to rook checks along 6th rank. Kd6 also: after Kd6, Nd5! attacking? d5 knight attacks... from b6 to d5, attacks c7, e7, f6, f4, e3, c3, b4, b6. And Nd5 attacks c7+? For king d6, Nd5 isn't check but Nc7? no. But after Kd6, knight can go e4? White Nd5 threatens Nf4? Meh. Kd8: allows Nc8?? c8 attacks... king d8? Knight c8 doesn't attack d8. Nc8 attacks a7,b6,d6,e7. Not helpful. But Kd8 allows nothing bad? Kd8 then Be7 possible. Also Rh8+?? Rh1-h8 check? Kd8, Rh8+ Ke... check along 8th, king must... d8 king, Rh8+ Ke7? d8 to e7 fine. Meh. Maybe Kf7: allows Nd5? not check. Nd7+? d7 doesn't attack f7. Kf7 then Be7/Kf6... Kf7 attacked by nothing? Knight b6 no. Rh1-h7+?? h7 occupied by own pawn — Rook can capture h7! Rh1xh7+!! King on f7, Rh7+ check? Rook h7 attacks f7 along 7th? h7-g7 (own black pawn blocks). So no. But Rhxh7 wins a pawn with check if g7... h7 rook attacks g7? g7 is black pawn; rook on h7 would be captured by g7 pawn? Actually Rh7+ — is it check? King f7, rook h7, path h7-g7-f7: g7 blocked. Not check. But rook on h7 attacked by g8? Black could Rh8? no rook. g7 pawn could later... rook trapped? Rook h7 attacked by g7 pawn? Pawns capture diagonally; g7 pawn attacks f6 and h6. No. Bf8 attacks h6, g7... Bf8 attacks h7? No wait after king moves to f7, bishop f8 diagonal g7(h own pawn). Hmm. Kf7 seems fine, then plan Be7, Kg6 etc., bishop to h4/g5 attacking f2? Bf8-e7-g5/h4. Actually bishop e7, then Be7-g5? e7-g5: f6 empty, yes. Bg5 attacks? Or bishop h4 pressure b2... Alternatively Ke8/Kd8 then Be7, Bd6 hitting h2? Bd6 attacks h2? d6-e5... no, Bd6 attacks f4, g3, h2 — yes! d6-e5-f4-g3-h2 diagonal. Pressure f2 too via... Bd6 attacks h2 and b4. Also Black could aim Bb7-c8-a6 hitting b2? Bc8 attacked by Nb6 though. Down 8 pieces, honestly the knight on b6 will escape soon (Na4 etc.). Just play solid: Kd7 illegal. I'd choose Kd8 or Ke8 to free f8 bishop. Ke8: allows nothing? Rh8+? Rh1-h8+ then Kf7. Knight forks? Nd7 no. Ke8 fine. Kd8: allows Nc8?? attacks e7... king d8 no. Actually Kd8 allows Nd7?? not check, Kxd7? d7 adjacent to d8, knight attacked — if Nxd7? Wait White knight on d7 would be capturable by Kd8xd7. Fine. Better: Ke8! Then Be7 next, then bishop can go c5 pressuring b4/g1... or Kf7. Also with Ke8, Black threatens Be7 then Bd6 attacking h2. And g5/g6. But wait — after Ke8, White Nd5 threatening Nc7? Not much. Or White Bd3/Ke2 solid. Also consider g5 immediately: after g5, Bf8 still blocked. g5 intent: Kg7 later? g5 weakens. Hmm, another tactical check: does Black have any shot? Bc8!?: attacked by knight b6, if Nxc8 then... nothing. But Bc8 threatens Bb7? no. What about c5!? defends against Nd5+ ideas? If Nd5 then c4? Not relevant. Actually if Black plays c5, then Nd5 is met by... knight d5 attacked by c6 pawn? After c5, pawn moved from c6. Bad. Maybe Ba6!? attacking? No. I'll play Ke8, planning Be7, Bd6/Be7-g5, and consolidate. Quip about storage fees. Actually consider Kd7?? illegal (knight). Kd6? I worried Nd5 ideas. Let's compare Ke8 vs Kd8: Ke8 allows Rh8+ only after... fine. Ke8 also allows Nd7!? not check, Kxd7 wins knight? Wait Kd8xd7 or Ke8... knight on d7 adjacent to both. But Nd7 would attack Bf8 while being attacked by king — White wouldn't. One more: is there Nd7 discovered issues? No. Go with Ke8.

Given the material deficit, my priority is unblocking my light-squared position — the f8-bishop is completely entombed by my own king on e7, and once it gets out to e7/d6/g5 it can start causing real trouble on the kingside dark squares. The knight on b6 is a nuisance but can be challenged or let go if needed. Ke8 frees the bishop's diagonal immediately.

Position: White up a lot. Knight on b6 forks... Black king e8, bishops b7 and f8. Nd7+? Knight from b6 can go d7, forking king e8 and... d7 is protected by king? Nd7+ Kxd7 wins knight. No, Nd7+ from b6 attacks e8 and f8? Knight on d7 attacks f8, b8, f6, b6, c5, e5. It gives check to Ke8? d7 knight attacks e8? No — knight on d7 attacks: b8, b6, c5, e5, f6, f8. Not e8. So Nd7 doesn't check; it forks f8 bishop, but Ke8 could... Kd8? Actually Nd7 attacks f8 bishop. Black replies Kd7 or Bxd7? Bb7 doesn't attack d7... Bf8 can't take d7 (dark-squared? f8 is dark, d7 is dark — yes diagonal f8-e7-d6... no, d7 not on that diagonal; f8-e7-d6-c5. d7 isn't reachable). King on e8 can take d7? Kd7... wait knight on d7, adjacent to e8. Ke8 can capture Nd7? e8 to d7 is adjacent, yes, but is d7 defended? No. So Nd7?? Kxd7 loses knight. Better: Na8? attacks b7 bishop... but bishop can move. Knight on b6 currently attacks a8, c8, d7, d5, a4, c4. It attacks... b7 bishop? No, knight on b6 attacks a8 and c8 squares. Bishop b7 is attacked? Knight on b6 attacks squares a8, c8, d5, d7, a4, c4. Not b7. So knight attacks nothing but restricts. Strongest move: probably advance passed pawns / activate pieces. White has knight on b6 deep, king c1, bishop f1, rook h1. Plan: h4, g4, etc. Or Bd3 development. Or Rg1... Best practical: get pieces active — Bd3 hits b7? Bd3 attacks g6? Diagonal d3-c4-b5-a6 and d3-e4-f5-g6-h7. Attacks h7! Bd3 threatens Bxh7? No, h7 defended by... nothing! Black pieces: Ke8, Bf8, Bb7, pawns g7, h7, c6. h7 defended by nothing. So Bxh7 is a threat... Bd3 then next Bxh7 wins a pawn and creates passer. But Black could react. Actually immediate Bb5+!? check: bishop f1 to b5 gives check to e8? b5-e8 diagonal: b5-c6-d7-e8. c6 pawn blocks! c6 pawn on c6. So Bb5+ not check... actually c6 blocks. Hmm, Bb5 attacks c6. Consider Na4-Nc5 etc. Or simply push h4/g4, march pawns. With up 8 material and knights forking threats, just win simply. Let's think tactics: Nd5 threatens? attacks c7, e7, f6, f4, b6... not much. Na8 traps knight somewhat? Na8 attacks b7 bishop; bishop moves, then knight stuck on a8? Bad. Simplest strong: Bd3 attacking h7 and b7... no, d3 only one diagonal. Bd3 attacks h7. Black must watch Bxh7 winning pawn and then h-passer. Also could consider b4, a4 pushing. Also Kd2 centralize. Actually is there a fork: Nc8!? attacks b7? Knight on c8 attacks b6, d6, e7, a7. Attacks e7 near king. Threatens Nxa7? no pawn. Nc8 also attacks... not great; Black plays Bxc8 removing knight? Bb7 can take c8? b7-c8 diagonal yes! Bxc8 wins knight. Bad. Nc4? attacks b6... nothing. Then Nd6+ fork? Nd6+ forking king e8 and f7... no rook. Nd6+ Ke7 then knight attacked by... Bf8? No, f8 can't reach d6... f8-e7-d6 — bishop on f8 on diagonal f8-e7-d6, yes if king moves from e7. Nd6+ Ke7, then Nxf7?? no. Nd6 attacks c8, e8? d6 knight attacks: b7! b5, c8, e8, f7, f5, e4, c4. Nd6+ forks king e8 AND bishop b7! Knight on d6 checks e8 and attacks b7. Black defends: Ke7, Kf8? or Bd6? Bb7 can't take d6. King moves: Ke7 attacks d6? No, e7-d6 adjacent yes! Ke7 then knight must retreat but could take b7... wait after Nd6+ Ke7, Nxb7 winning bishop, knight then... attacked by king? Kd7 then knight b7 escapes via... b7 attacked by king d7? No, d7-b7 not adjacent. Knight escapes. So Nd6+ Ke7 Nxb7 wins bishop! Wait check: does Nd6 give check? Knight d6 attacks e8 — yes, d6→e8 is a knight move. Check. Black responses to Nd6+: - Kf8? d6 knight attacks f7, f5, e8, e4, c4, c8, b5, b7. Not f8. Kf8 then Nxb7 wins bishop (b7 bishop). Knight b7 then attacked by? Nothing. So wins bishop. - Kd7 attacks d6 knight? Yes. Then Nxb7+!? Kxb7?? no, king d7 to b7 not adjacent... Kd7, Nxb7+ check? Knight on b7 checks d7? b7 knight attacks d6, d8, c5, a5. Not d7. Hmm, Nxb7 then Kc7... knight escapes via a5? b7-a5. Or knight d6 attacked by Kd7, retreat: Nxb7 anyway? Knight on d6 moves to b7 capturing bishop; is b7 safe from Kd7? d7 to b7 not adjacent. Then knight on b7 attacked by nothing. Yes wins bishop. - Kd8/Kf8/Ke7: all, then Nxb7. - Bd6?? not possible. - Bb7xc6? irrelevant. So Nd6+ forks and wins the b7 bishop! Wait, does Nd6 get captured after? Black king on e8, after Nd6+ Ke7, Nxb7 — knight on b7, king e7 can approach: Kd7 attacks b7? No. Kd6? attacks b7! Then knight must move: Na5, Nc5, Nd6, Nd8. Na5 fine. So wins a bishop. But wait: also check Nd6+ — is knight on d6 attacked by pawn c6? No, pawns don't attack backward... c6 pawn is black, moves c6-c5, attacks b5 and d5. Not d6. So 22. Nd6+! wins bishop. Verify legality: knight b6 to d6 — b6→d6 valid knight move. Yes. Even better, does Nd6+ create bigger fork? Knight on d6 also... just check + bishop. That's clean.

The knight on b6 is sitting on a fork spring — Nd6+ hits the king on e8 and the bishop on b7, and the c6 pawn can't stop it.

Tried Nd6+Knight on b6 cannot legally move to d6. Knight on b6 can play: Na8, Nc8, Nd7, Nd5, Nc4, Na4.

b6 to d6 isn't a knight move (two squares same direction — oops, that's a two-step, not knight move). Knight forks: from d7 attacks f8 bishop and... not e8. Hmm. Fork options: knight b6 → c8 attacks e7, a7, b6, d6. Knight d7 attacks f8 bishop (and b8, b6...). Nd7 threatens Nxf8 winning a bishop, but Ke8 can defend or capture? Kxd7! d7 adjacent to e8. Is d7 defended? By anything? No white piece defends d7. So Nd7?? Kxd7. What about a check first? Bb5+ blocked by c6. Hmm, no checks available except... none. Alternative plan: Na8 then... no. Nc4 then Nd6 later. Better: attack b7 with Bd3? Bd3 attacks h7 not b7. Bb5 attacks c6 and... a6? b5-a6. Bb5xa6? nothing there. Bb5 pins/attacks c6 pawn; c6 defended by b7 bishop. b2-b4? not attacking. Try winning h7: Bd3 (threat Bxh7). Black then can't defend h7 easily... g6? No pawn. Bg6? f8 bishop can't. Actually Black could just continue; White wins h7 and creates passer with 4 pawns vs 1 (g7). Good plan. Or combine: Bd3 threatens Bxh7 and supports... Let me check Black's counterplay: Black has bishops only, passive. Nd7 later? Or first Kd2, Rg1. Actually Nd7 attacking f8: Nd7 attacks f8 bishop! But Kxd7 takes knight. Unless knight d7 protected — could protect by Bf1... no. So no. Can I win b7 bishop? Knight c8 attacks... e7, b6, d6, a7. Nc8 threatens Nxa7? no. Nc8 attacked by Bb7 (b7-c8 diagonal) — Bxc8 wins knight for bishop (trade bishop for knight, still up material but bad). Not good. Threat Na8 attacks b7? Knight on a8 attacks b6, c7. Not b7. Hmm, knight can't fork b7 easily. So best plan: activate. Bd3 threatening Bxh7 seems strong. Also Kd2/Rg1. Check Black threats: none really. Bd3 also opens path. Let me play Bd3. Actually wait — consider Nd5!? then Ne7 forking? Knight d5 attacks: e7, f6, f4, e3, c3, b4, b6, c7. Nd5 threatens Ne7 forking g8... king e8 defends e7? Yes. Hmm. Simplest winning: push pawns and take h7. Bd3.

My knight geometry failed me — b6 to d6 isn't a hop, it's a march. Back to plan A: activate the bishop and threaten h7.

White Bd3 eyes h7. Black is down massively. Black moves: Ba3 grabs b2 pawn? White has no light bishop... wait, Bd3 is light-squared. Black Bb7 is light. White threats: Bxh7? White Bd3 attacks h7, defended by g7. Bxh7 would trade B for pawn... actually g7 defends h7, so Bxh7 Bxh7. Black could play Ba3 grabbing b2 pawn? b2 defended by Kc1, Ra1 no rook is h1. Rb1? Rook on h1 doesn't defend b2. So Ba3 attacks b2 which is defended by Kc1. Not winning pawn. Better: activate. c5 passed pawn, Bc5 attacking... Ba3 hits b2 and forces K moves? Ba3 then Kd2? Kc1 defends b2. Threat: Bb7 is trapped-ish? Bb7 attacked by Nb6. Nb6 attacks b7... wait Nb6 is on b6, attacks a8, c8, d7, d5, a4, c4. Not b7. So Bb7 safe, actually attacks c6? No, Bb7 attacks c6 pawn (own pawn). Black pieces: Bf8 can go e7, d6, c5, b4, a3, c8, a8? Ba8 blocked by Nb6 on a8? Nb6 on b6, a8 is free... Ba8 legal per list. Also Ba8 then Nb6 can't capture? a8 is bishop's home; N attacks a8 and c8. Ba8 puts bishop attacked by Nb6? Knight on b6 attacks a8 yes. So Ba8 hangs to knight. Bc5 attacks... nothing much. Bb4 attacks? Bb4 could pin... no white pieces on line to Kc1: b4-c3-d2-e1... Kc1 not on diagonal b4. Bb4 attacks Kc1? b4-c3-d2-e1: no. c5 push: pawn c5, then Rh1xh7? Rh1 attacks h7 through h2? Own pawn h2 blocks. Black best: maybe Kf7 and push kingside pawns, try counterplay. Material is hopeless; play Ba3 to threaten b2? Kc1 guards. Consider Bb4 aiming at... then a3? White pawns a2 could hit Bb4 with... a3 push. Maybe Bc5 threatening b2 with... c5-b4-a3 diagonal toward b2: Bc5 then Bb4 then Bxa3? slow. Honestly any move roughly fine; pick Kf7 to get king active and stop... Actually White threat is Bxh7+!? Bxh7 g7 recaptures—just pawn trade. Not much. Pick Bc5 heading to b4/a3 to win a2? Or g6 to break. I'll play Kf7, supporting g5? Quip. Actually maybe Ba3 is strongest: attacks b2; if Kd2 then Rb1... rook must move to defend? Rook h1 to b1 defends b2. Meanwhile bishop on a3 attacks nothing else. Meh. Bc5: prepares Bb4-a3 hitting b2 again; Kc1 defends b2 always. So no. Kf7 activating king, planning g5, Kf6. Go with Kf7. Quip: "Down material? Details. My king is clocking in for overtime."

Material's a disaster for me, so it's time to get every piece — including the king — hunting. I'll step up, keep an eye on those kingside pawns, and look for any slip.

GLM 5.3 High· move 23

Material is way up; find a strong move. Bxh7? That's a pawn but bishop on f8 defends h7? Bishop f8... h7 pawn: Bf8 defends h7? f8 to h7? No, f8-h7 isn't diagonal (f8, g7, h6). g7 pawn defends h7... actually g7 pawn is on g7, defends... pawn on g7 defends f6 and h6, not h7. So Bxh7 wins a pawn? Bishop d3 takes h7 pawn. Is h7 defended? King f7 is adjacent? f7 to h7 not adjacent. So Bxh7 just wins a pawn. But Be4 maybe stronger, hitting b7. Or Bg6+!? Kg6... Bg6+ Kxg6? No, g6 defended by king f7 adjacent — Bg6+ Kg... wait king f7 attacks g6, so bishop g6 would just be captured. No, wait it's check? Bg6+ — bishop on g6, king f7. Is that check? f7 adjacent to g6, king captures. Not check... actually diagonal g6-f7, yes it is check but king just takes Kxg6. Bad. Bxh7 wins a pawn safely. Also knight b6 is attacked by Bb7? Bb7 attacks b6? No, b7 to b6 isn't diagonal. Knight b6 attacked by... nothing; but knight is attacked by c6 pawn? c6 pawn attacks b5 and d5, not b6. Pawn c6 could... pawn moves forward. Nxc8? Knight attacks b7, c8, d7, a8, d5, a4, c4. Knight attacks b7 bishop. Knight is attacked by bishop b7? No. Bxh7 wins a pawn and keeps knight fork threats. Also Nb6 attacks... does Be4 threaten Bxb7 winning another piece? Be4 hits b7 bishop. If Be4, Black bishop retreats or plays Bxb6? Bxb6 wins a piece? Bishop b7 takes knight b6? b7-b6 not diagonal. Actually bishop on b7 could take knight... no. Black could just lose b7 bishop with Be4. But Black's Bf8 covers... f8 doesn't cover e4? f8-e7-d6... no. So Be4 attacks b7, undefended? b7 defended by king? f7 not near. So Be4 wins a piece? Black would move bishop. But Be4 blocks... Also Bxh7 first then Be4 later. Actually Bxh7 then Bf8 can play Bxb... hmm. Actually Bxh7: bishop on h7 then trapped? h7 bishop can be trapped by ... g6 or king g6. After Bxh7 Kg6? Then king attacks h7 bishop; escape via g8? h7-g8 yes. So Bxh7, K moves, Bg8 or Be4. Bxh7 wins pawn, up 9. Alternatively Be4 immediately attacks b7; Black plays something like Bc8 attacking b6 knight? Bb7-c8 attacks knight b6. Knight defended by a4? Nb6 defended by... nothing? a-pawn on a2. Knight b6 attacked by Bc8 after retreat. So Be4 Bc8 attacks Nb6; knight moves (Nd5, etc.). Meanwhile h7 still hanging. Simplest strong: Bxh7 wins a pawn. Or Be4 then Bxb7 if allowed. I'll play Bxh7.

Position: Black to move, move 23. FEN: 5b2/1b3kpB/1Np5/8/8/8/PPP2PPP/2K4R b - - 0 23. White: Kc1, Rh1, Bh7, Nb6, pawns a2,b2,c2,f2,g2,h2. Black: Kf7, Bf8, Bb7, pawns g7, c6. Material: Black down. Is there any tactic? Black's Bb7 — attacked? White knight b6 attacks c8, a8, d5, d7... Rh1 attacks h-file, h7 is own bishop. Bh7 attacks g8, f5, e4, d3, c2... g8 square empty. Black Bb7 is attacked by Nb6! Nb6 attacks b7? Knight on b6 attacks a8, c8, d7, d5, c4, a4. Not b7. Bishop b7 is safe. Bf8 attacked by? Nothing. Bh7 attacks g8. King f7 is fine. Is there any saving tactic? Black pieces: Bf8 can go various squares. Bb7 - Bb4, Ba3? Bb7 to a8? Bb7 diagonal: a8, c8, a6, c6(own pawn), d5, e4, f3, g2, h1. Bb4/Ba3 illegal for b7 bishop? b7 bishop moves on diagonals: a8, c8, c6(own), a6, d5, e4, f3, g2, h1. Bb4 etc. are from f8 bishop (diagonal a3-f8: e7,d6,c5,b4,a3; and g7-own). Wait — the Bb7 bishop... does it defend c6 pawn. c6 pawn attacked by? Nb6 doesn't attack c6. Nothing attacks c6. White threats: Rh1 to h7 is own bishop; Bh7 aims at g8. Also maybe Bg8 then... nothing. Is Black actually losing? Material 17-8, 9 points down with bishop vs bishop+knight + rook + 5 pawns... wait count: White has R+B+N+5 pawns = 3+3+3+5 = 14? They said 17... whatever. Black has B+B+2 pawns = 8. Down a rook essentially. Any tactics: White's Bh7 and Rh1 battery — Rh1 can't be behind h7. Bh7 attacks g8; if Bxg8?? no. Can Black win the h7 bishop? Kf7... Bishop h7 protected by Rh1. Black could try ...Be5 ideas? Black Bf8 to h6? Not possible — f8 diagonal: g7 own pawn blocks. After g6, bishop gets to h6... Simplest: play Be7 or Bd6, consolidate, maybe play c5 to free bishop. Threats? White Bh7 threatens Bg8 mating? g8 square: covered by Bf8 and Bb7? Bb7 diagonal b7-a8-c8? no, a8-c8 diagonal... b7 to c8 is diagonal, g8 not on b7's diagonals (b7 diagonals: a8,c8,c6,a6,d5...). Bf8 covers g7, h6, e7, d6... not g8. Actually g8: attacked by Bh7, defended by nothing. But Bxg8 wins a bishop for bishop — Bh7 defended by Rh1, so Bxg8?? no, g8 is empty; Bg8 by white would be met by Bxg8 winning a piece for a bishop (Rh1 defends? Rh1 on h-file, g8 not on h-file). Wait Rh1 defends h7 only. So if white plays Bg8, black Bxg8! wins the bishop since g8 is not defended. Also white threatens Rh8+? No, h7 bishop blocks. White threatens Bg8 and maybe Bxf... Black's real problem: king safety and being down material. Maybe try for activity: Bc5 hitting... nothing. c5 pawn move attacks Nb6 and frees Bb7 diagonal (c6 to c5, bishop to a6 hitting... a6, then Bxb? nothing). Any immediate tactic: Bb4 threatens? Bb4, if White Bc2? hmm. Bd6 attacks? Nothing. Be7 then Bh4+? After Be7, black bishop eyes h4 — check to Kc1! Be7, then next Bh4+ ideas. But White will respond. What about g6 to make luft and free bishop to h6? Bishop f8 can go g7? No own pawn g7. g6 frees f8-g7-h6 diagonal? No, g7 pawn moves to g6, opening... f8 bishop diagonals: e7-d6-c5-b4-a3 (open), and g7-h6 blocked by own pawn. After ...g6, ...Bh6 possible? f8-g7-h6: yes after pawn moves to g6, g7 empty. Bh6 attacks... g7, f4... Rh1? No. Bh6 attacks Bg7? Nothing. Bishop h7 of White is somewhat stuck. Knight b6 attacked by? c6 pawn? c6 pawn doesn't capture b6 (pawns capture diagonally: c6 pawn captures b7/d7 — wait black pawn on c6 moves down, captures b5/d5). Hmm, does anything attack Nb6? c7 pawn? none. Knight b6 is safe. Maybe ...c5 attacking Nb6! c6-c5 attacks knight on b6 (pawn c5 captures to b4/d4... no wait pawn on c5 attacks b6 and d6? Black pawn on c5 attacks b4 and d4). No! Black pawns attack downward: c5 attacks b4 and d4. So c5 doesn't attack b6. Black pawns capture toward rank 1. So c6 pawn attacks b5 and d5. So no attack on knight. Black is just lost. Best practical: Be7 developing, aiming for Bh4+ checks maybe. Or Bd6. Or Ba8/Bc8 freeing bishop from b7? Bishop b7 could go to a6 attacking c4? nothing. Actually check white threats: Bh7 threatens Bg8! If Bg8 then Bxg8 wins piece — good for black actually, white wouldn't. Rh1 threatening Rh8? blocked. So no immediate threat. Best move: Be7 or g6. Let me consider Be7: after Be7, White might play Bd3? or Nb6-d5 hitting c... Nd5 threatens? Knight d5 attacks e7 bishop, c7, b6, f6... Nd5 attacks Be7. Then bishop moves, maybe Bh4+!? Kc1... Bh4+ then g3? White has g2 pawn: g3 blocks... pawn g2-g3 blocks check, then Bxg3! fxg3? No wait Bh4+ , g3 pawn to g3 blocks, Bxg3 fxg3 wins bishop for pawn. Bad. Alternative: Be7, then Bc5 aiming... eh. Another idea: ...Bc5 immediately, threatening? nothing much. Maybe ...Ba8? Bishop to a8 keeps... attacks h1 rook along a8-h1 diagonal! Ba8: a8-h1 diagonal: b7... wait bishop b7 to a8, then a8-h1 diagonal passes b7 (now empty), c6 own pawn blocks. No. Bc8? then a8... Bc8 attacks h3? c8-h3 diagonal: d7,e6,f5,g4,h3 — empty! Bc8 threatens nothing concrete (h3 empty), but if g-pawn... eh. What about immediate checks? None. I'll play Be7 — solid, connects... actually let's consider Bd6: Bd6 attacks? nothing. Be7 eyes h4 check square. I'll go Be7. Quip: cocky.

Material's lopsided, but I'll tuck the bishop in on e7 and eye that h4-check square — miracles start with small steps.

Position: White up big material. Black king f7, Bh7 attacks... Bh7 attacks g8 and f5. Black bishop on e7 guards g5/f6? Bg8+ checks king, king can't take (g7 pawn? No, king on f7, g8 bishop — king can capture Bg8? Kxg8 — g7 pawn is on g7... wait Black has pawn g7. King f7 can move to g8? Bg8+ — is it protected? Bishop on h7 moving to g8, check from... bishop on g8 attacks f7 diagonally. Can king capture? Kxg8 illegal because bishop protected by... nothing? Actually bishop on g8 would be protected by nothing — but Kxg8 then bishop captured. Wait, bishop on h7 to g8: from g8 bishop checks f7 king. King takes g8? Then... is g8 defended? No White piece defends g8. So Kxg8 recaptures, losing a bishop. Bad. Bg6+ — bishop g6 checks f7. Kxg6 also possible? Bishop g6 defended by nothing... king takes. Bad. Bd3 retreats, keeping extra piece. Nd5+ forks? Nd5+ checks f7? Knight d5 attacks f6, e7... knight on d5 attacks e7, f6, b6, c7. Not check on f7. Best: just consolidate. Bg8+?? loses bishop. Maybe Nd7 forking... Nd7 attacks f8, b8, f6, b6, e5, c5. Not check. Simplest strong move: Bd3 or f4. Actually Bf5+? Bf5 — bishop h7 to f5: f5 attacks f7? No, f5 bishop attacks e6, g6, e4, g4 — not f7. Not check. King safety: Black Bb7 attacks f3? No, b7 bishop attacks a8... diagonal b7-a8 and c6-d5-e4-f3! Yes, Bb7 hits c6 pawn? White pawn c2. The bishop attacks e4, f3, g2. So g2 is attacked by Bb7? b7-c6? c6 is occupied by black pawn. Diagonal blocked. b7-c6 blocked. So no. Just play Bd3 or Na4, push pawns. Material up 9. Bg8+ Kxg8 loses. So retreat bishop: Bd3 keeps everything. Or Be4 hitting c6 pawn and e7 bishop? Be4 attacks c6 and... c6 defended by b7 bishop. Trade bishops would still be fine but keep bishops. Actually a nice trick: Bg8+!? No, Kxg8. Nd5 attacks Be7? d5 knight attacks e7! And f6, c7. Black bishop e7 attacked. Be7 defended by king f7. Knight protected? d5 protected by... nothing. So Bxd5 wins knight? c6 pawn attacks d5! Black c6 pawn defends d5. So Nd5? Bxd5 no wait — c6 pawn can capture d5? c6 pawn captures b5 or d5. Yes cxd5. So Nd5 loses knight to cxd5. Avoid. Be4 attacks c6 pawn (defended by Bb7) and hits e7? e4-f5-g6 diagonal; c6 via d5. Bxc6 Bxc6 trade, fine but unnecessary. Best: consolidate. Bd3 safe. Also could do Na4 keeping knight safe. Knight b6 attacked by... Be7 doesn't attack b6. Bishop b7 doesn't. So knight is fine. Simple strong move: Bd3 or f4. Let me consider activating rook: Rg1 targets g7? g7 defended by king. Rf1, Re1, Rd1. Also consider Kb1 for safety? Bb7 attacks... nothing right now. I'll play Bd3, protecting against back-rank stuff and connecting. Or better: maybe Na4-c5 forking? Na4 then Nc5 attacks e6, b7 bishop! Na4 attacks... then Nb6 was fine. Knight on b6 attacks c8, d7, a8. Nc8 threatens Nxd... Nd6+? Nc8 threatens Na7? Hmm. Actually Na8!! Knight to a8 attacks c7... traps itself? Na8 — knight attacked by nothing, but it's cornered. Just solidify: Bd3 keeps bishop safe. After that, advance pawns and win. Let me verify Bd3 legal: h7-g6-f5-e4-d3 diagonal clear. Yes. Alternatively f4 then Bf5 pinning? Bf5 attacked by nothing? Bishop f5 — Black king can't reach. Bf5 attacks d7, e6... fine too. I'll play Bd3 with quip.

Let me look at this. My bishop on h7 is attacked by nothing yet, but Bg8+ would just lose it to Kxg8 (nothing defends g8). The knight must stay off d5 (cxd5!). I'm up a mountain of material, so I'll consolidate cleanly — the bishop retreats to a safe diagonal, eyeing Black's whole kingside.

GLM 5.3 Flash High· move 24…

Down 9 points material. Black: Kf7, Bb7, Be7, pawns g7, c6. White: Kc1, Rh1, Bd3, Nb6, 7 pawns. Black has two bishops vs knight; down a lot but let's find best defensive moves. Legal: Ba8, Bc8, Ba6, Bd8, Bf8, Bf6, Bg5+, Bh4, Bd6, Bc5, Bb4, Ba3, Ke8, Kf8, Kg8, Kf6, Ke6, g6, g5, c5. White's Nb6 attacks... Nb6 can go to c8? attacks a8, c8, d5, d7, a4, c4. Black bishop b7. Rh1 attacks h-file/h7? h7 empty. Bd3 threatens Bxh7? no h7 pawn gone; threats? Bd3 aims at... Bc4? Also c6 pawn attacked by Nb6? Nb6 doesn't attack c6. Actually c6 pawn attacked by Bd3? No, Bd3 on light squares? d3 is light square. c6 is dark square. Bb7 vs Bd3. Threats: White might play Bd3xf5? nothing. Perhaps Rh1-h7 attacking g7 pawn. Black bishops both on long diagonals? Be7 dark square, Bb7 light square... wait b7 is dark? a8 is light, b7 is... a1 dark, b1 light... b7: color = (b=2, 7) 2+7=9 odd → dark? Standard: a1 dark. Square color dark if file+rank even. b7: 2+7=9 odd → light square actually. Hmm, a1 dark, a2 light... parity: dark if (file+rank) even. b7: 2+7=9 odd → light. So Bb7 light-square bishop, Be7 (5+7=12 even → dark) dark-square bishop. Good bishop pair covering both colors. Down 9 points; likely losing but try. Best practical: keep bishops, maybe activate. Bf6 or Bg5+? Bg5+ check, then... White could block. Check evaluation: Bg5+ Ke6 then what? Not much. Consider Bc5 eyeing b4/b6 knight? Bc5 attacks Nb6? No, c5-b6 diagonal yes! Bc5 attacks b4, b6... c5 to b6 is adjacent diagonal. Bc5 attacks the knight b6 and threatens Bxb6 winning a piece (down 9, need trades). White would move knight or defend. Knight can move with tempo? White Nb6 could go d5, c4, a4, d7... Also Rh1 can take g7? Rhxg7? No h7 empty so Rh1-h7 then Rxg7. Actually g7 pawn is only defended by Kf7. So White threat Rh7 Rxg7. Also Bd3 threatens? Bd3 attacks h7... nothing there. Bd3 could be attacked by Bb7? b7-d3? No. Better: c5 advance? c5 attacks Nb6? c6-c5 doesn't attack b6... pawn c5 attacks b6 and d6! Yes pawn on c5 attacks b6 knight. That forks? c5 also hits d4. So c5 attacks knight. And pawn on c5 is defended by? nothing, but Nb6 could capture... Nb6 can't capture c5? Knight b6 to c5? No, knights don't move one square diagonally. Nb6 attacks a8, c8, d7, d5, c4, a4. So c5 pawn attacks knight, knight must move or... it could be defended by Bd3? No. So 24...c5 attacks Nb6. White replies maybe Nd5 or Nc4 or Bd3xc5? Bd3 to c5? d3-c5 not a bishop move? d3 to c5 is not diagonal... d3, c4, b5, a6 diagonal; d3 to e4... So Bd3 can't take c5. Knight must move: Nd5 forking? Nd5 attacks c7, e7 (bishop!), f6, f4, e3, c3, b6. Nd5 attacks Be7 and... Nd5 threatens Nxe7. Then Be7 could move? If 24...c5 Nd5 attacks e7 bishop and c7 pawn gone... Then Bxd5? Bb7 can't reach d5 (b7-c6 blocked by own pawn... b7 to c6 is own pawn; also b7-a6/c8). Be7 moves, then Nxc5? Hmm. Alternatively 24...Bc5 attacking Nb6; if Nd5 (defending? no), White plays Bd3-f5? Or knight moves: Nc4 then Bxb4? no. Let's compare c5 vs Bc5. After 24...c5 Nd5, Black plays? c6 pawn is pinned-ish? Bb7xd5? blocked by c6 pawn. So Be7 must move: Bd6/Bf6/Bf8/Bg5/Bh4. Then Nxc5 winning a pawn, material 18-7. Bad. 24...Bc5: attacks Nb6. White options: Nd5 (attacks Be7, Bc5? Nd5 doesn't attack c5). Nd5 attacks e7 bishop. Then Black: Bxd5? No. Bf6 saves bishop, then Bxb6? White could interpose... After Bf6, White plays Bb5? Hmm. Or after Bc5, White knight retreats: Nd7 attacking Bc5? Nd7 attacks c5! Then Bb6? no... Bd7 attacked by... Actually Nd7 attacks c5, b6, b8, f8, f6, e5. Then Black bishop moves, maybe Bb4 or Bb6 still eyeing knight? Bb6 then White king... eh. Alternatively 24...c5 might just be stronger because knight is stuck on b6 (boxed) and pawn gains space. But Nd5 hits e7. Actually what about 24...Bd6!? preparing Bc5 with pawn c6 defended? Bd6 protects c5 square, then c5 next. But c6 pawn... White Nb6 could take? Nb6 attacks? not c6. Maybe simply 24...Bf6 solidifying g7 against Rh7 ideas and preparing ...g5. White threat Rh7 Rxg7? With Bf6 defending g7. Also Bf6 eyes c3/b2. Check immediate White threats now: Rh1-h7 then Rxg7 winning pawn (Kxg7?? then Bc4+? no). Actually after Rh7 Rxg7 Kxg7 White gets nothing else; it's just a trade rook for pawn? No—Rxg7 Kxg7, White loses rook for pawn, bad. Rh7 threatens Rhxg7? That loses rook for pawn. So no real threat. White threats: Bd3-c4? Nothing. So White has no forcing threats; position: White up rook+ pieces. Black plan: consolidate, try to trade. Bc5 offering trade of bishops? Bc5 attacked by nothing immediately. If knight moves, Bb4/Ba3... aiming at b2. Also consider Ke8-e7? King activation weird. I think 24...Bc5 is natural: develops, attacks knight, eyes b2. Let me check knight responses: Nc4 attacks Bc5? No, Nc4 attacks b2, a3, a5, b6, d6, e3, e5, d2. Nc4 attacks b2 pawn. Then Bxb4? no. After Nc4, Black could play Ba3? Bb4 attacking knight? b4 attacks c3, a3, and knight at c4? No, b4-c4 not diagonal... b4 attacks a3, c3, a5, c5, d6, e7... Knight on c4 not attacked. Bxb2? Bc5xb2? c5-b4-a3 blocked? No, c5 to b4 to a3 diagonal; b2 not on that diagonal. Bc5 diagonal: b6, a7 / d6, e7... / d4, e3, f2! Bc5 attacks f2. Interesting: after Bc5, bishop eyes f2. Nd5 also possible: attacks e7; Black plays Bf6 or Bg5 or Bd6... Bg5+!? If Nd5, then Bg5+ Ke6?? King would... Bg5+ check, Kf6? hmm. Actually after Nd5 Black just moves bishop: Bf6 defending g7, then Nxc5? knight d5 to c5? Not knight move... d5 knight attacks c7,e7,f6,f4,e3,c3,b4,b6 — not c5. So c5 pawn safe. So lines fine. Alternatively 24...g6 to solidify. I'll play Bc5. Wait — does Bc5 hang anything? White Bd3 could take? No. Rh1? No. Knight must deal. Also after Bc5, White could play b2-b4? Pawn b4 attacks c5 bishop. Then Bxb4? bishop takes pawn: cxb4? c6 pawn could recapture... Bc5xb4, then Nxb4? knight b6 can't take b4? b6 to b4 no. Then Black bishop on b4 attacked by? nothing much. Actually White probably plays Nd5 first. Fine, Bc5. Quip: something cocky about hunting the knight.

Two bishops versus their scattered horde — time to start hunting. My dark-squared bishop eyes that stranded knight on b6 and the f2 pawn behind it.

Played Bc5

Bc5e7 → c5

My bishop just put your knight in the crosshairs — down a few trophies, but I collect heads now.

GLM 5.3 High· move 25

Black threatens Bxb6? Actually bishop c5 attacks Nb6. Also Bb7 attacks... Nb6 is attacked by Bc5 and defended by? Nothing? Bd3 doesn't defend b6. So knight is attacked. Also Bb7 attacks... hmm. Black bishop c5 attacks b6 knight. Also threatens ...Bxb6 winning knight back, reducing material but White still up a lot. Best move: Bc4+? Check from c4 hits f7 king? Bc4+ — bishop on c4, diagonal c4-d5-e6-f7: yes check. King can move... Kf7 on f7. Check options: Kf8, Kg8? Kg8... Bc4+ Ke7/Kf8/Kg8/Kf6. Also Bg6+ check? Bd3-g6+ hits f7. King moves. Better: defend knight or move it with tempo. Nd5 attacks c7... nothing there. Nc4 attacks? Knight to c4, defended? Bxc4 by Bc5... c4 defended by b3? No pawn on b3. Nc4 would be captured by Bc5. Nd7 attacks? Knight attacks... f6, f8, b8, b6, c5! Nd7 forks king? No. Nd7 attacks c5 bishop and... but bishop can take b2? Bd7 attacks c5 and f6/f8/b8/b6. But bishop c5 can just move away or Bxd7? No, c5 bishop doesn't cover d7... c5-d6-e7: no d7. Bb7 covers d7? b7-c6? blocked by pawn c6... b7 to d5: c6 pawn blocks. So Nd7 attacks Bc5 safely? After Nd7, bishop attacked by knight; knight attacked by? Nothing. But bishop moves with tempo maybe... bishop can retreat but then knight forks? Nd7 also attacks f8, f6, b8. Alternatively Bc4+ then knight escapes with tempo. Let's evaluate: Bc4+ Kf8 (or Kg8), then Na4/... knight moves. Actually stronger: Nc4?? Bxc4. What about Na4 — attacked by Bc5? No, a4 not on diagonal. Na4 safe. Nd5 attacked by? Nothing; attacks c7, e7, f6, b6... Nd5 also. Best line: Bc4+ Kg8 (Ke7?? then Nd5 forks? Nd5+ from d5 checks? d5-e7: yes knight on d5 attacks e7, check, winning bishop c5? No, bishop escapes. Hmm). Actually after Bc4+ Kf8, knight still attacked; move knight: Na8? or Nd7 — Nd7 attacks... and threatens? Or Nd5 attacking f6, e7, c7. Nd5 threatens nothing but safe. Alternative: Bg6+ Kxg6?? No, king can't take—Bg6+ from d3: is g6 defended? Nb6 doesn't defend g6. King f7 takes g6? Bd3-g6, king on f7 adjacent: Kxg6 possible if g6 undefended. Knight b6 doesn't cover g6. So Bg6+ Kxg6 loses bishop. No. So Bc4+ then move knight. Or defend knight? No defender available. Another idea: Nd5 first, offering bishop trade... Nd5 attacks e7 and f6 near king but bishop just moves. Actually Nd5 threatens Nxc7?? no pawn. Nd5 threatens nothing much but bishop must... actually knight isn't attacking bishop after Nd5? d5 knight attacks c7, e7, f6, b6, f4, b4, c3, e3. Not c5. So bishop remains attacking nothing; then Bxd5? Bishop c5 covers d6-e7-f8... and b4-a3. c5-d4? Not d5. Bb7 covers d5? b7-c6 blocked. So Nd5 safe. But Bc4+ first gains tempo; then knight retreats and we maybe win c6 pawn? Bc4+ attacks c6 pawn too! Bishop c4 attacks c6? No—c4-c5 has bishop in way... diagonal c4-d5-e6-f7. Not c6. It attacks f7 (check). After Kf8, Be6? attacks c8... hmm. Consider Bc4+ Kf8 then Nd5 threatening? Ne7 forking? Or Nc4 then... knight on d5: Ne7+ then? Kf8... Nxc8? Actually plan: Nxc8 winning bishop? After Bc4+ Kf8, Nd5 threatens Ne7?? no, e7 empty; Ne7 forks g8 and c8: Kf8 there, so Ne7+? Ne7 attacks g8 (empty) and c8... not check. Hmm. Simplest: Bc4+ Kg8, then Nxc8? No, knight b6 can't reach c8 in one—Na8 then? No. Let me think winning plan: up 9 points. Just keep knight safe and push kingside pawns. Bc4+ Kf8 (Kg8, Ke7). If Kg8, then Nd5 safe, then Nxc7 next? c7 empty. Actually there are no black pawns except g7 and c6. Threat: Bxc6! Bxb7... wait Bc4 after check could later take c6? Bishop c4: does it attack c6? No, c6 is on c-file, bishop diagonal. Bd3 attacks c6? d3-c4-b5-a6 and d3-e4-f5-g6-h7... no. Hmm, what attacks c6? Nothing currently. Bb5! Bishop d3-b5 attacks c6 and a6, also pins? Bb5 attacked by... nothing? Black bishop c5 covers b6... b5: c5-b4... c5-d4, c5-b4-a3, c5-d6-e7. b5 attacked by Bb7? b7-c6-d5... c6 pawn blocks b7-b5? b7 and b5 same file, not diagonal. So Bb5 attacks c6, c6 defended by Bb7. Trade? Bad trade not—equal bishops? White bishop for black bishop plus pawn c6? Bb7 takes b5? Bb7 attacks b5? No, b7 to b5 is same file. What defends c6: Bb7 (via c6? no...). b7-c6 is adjacent diagonal—yes Bb7 defends c6 directly. And who takes b5? Bb7 can't reach b5. Bc5? c5-b4... no. So Bb5 Bxb5?? impossible; black must defend c6: ...Bd6? or move. If Bb5, black plays Bc8? trading? Bc8 then Bxc6? no c6 defended still... Bb5 attacks c6, defended by Bb7. Fine. Best practical: Bc4+ (check), then move knight to safety with tempo already used. Let's check Bc4+ Kf8 then Nd7!? attacks? Knight d7 attacks b8, f8(forbidden square), f6, b6, e5, c5! Yes Nd7 attacks c5 bishop! And knight on d7 is attacked by? Nothing. So bishop must move or... Bxd7?? no. Bishop moves: Bxd7 impossible. So Bc4+ Kf8 Nd7 attacks c5 bishop, bishop retreats (Be7/Bd6/Ba7). Then maybe Ne5+? Knight d7-e5: attacks c6 pawn? e5 attacks c6, f7, d3... Ne5 forks c6 and threatens. Nice plan. Or even Bc4+ Ke7 then Nd5+? Nd5+ Ke8/Kf8, knight attacks c7,e7... then knight gains tempo but bishop can slide to b4 attacking? Hmm Bb4 after. Nd7 after Ke7 attacked by king! So careful. Bc4+ Kf8 Nd7 Bxd7?? impossible. Bishop retreats; then Bxc6! Bishop c4... c4 to c6? no. Hmm c6 pawn: attacked by Nb6 currently? Knight b6 attacks c8, d7, d5, a8, c4, a4. Not c6. Pawn c6 attacks b5, d5, b7, a7. After Nd7, knight attacks b8, f6, f8, e5, c5, b6. Pawn c6 still blocks Bb7. Whatever — Bc4+ Kf8 Nd7 is strong. But wait, does Bc4+ hang to anything? Bb7... c4 attacked by? Bb7: b7-c6? blocked. Nothing takes c4. Alternatively immediate Nd7 attacking bishop c5: bishop attacked, must move; then? Then Nd7 safe, and next Bc4+ maybe. Bishop moves: Bb4 attacks a5... Bd6, Be7, Ba7. Then Bc4+ etc. That's also fine but Bc4+ first is tempo. Wait: check whether Bc4+ has issue: after Kf8, bishop c4 and knight b6 both... then Nd7 forks... knight on d7 attacked by Bb7? b7-d5: c6 blocks. Attacked by king f8? No, d7 not adjacent to f8. Safe. Also alternative: Na4!? attacks? a4 attacks c5! Knight a4 attacks c5 bishop and c3, b6, b2. Knight a4 attacked by? Bb7? no. So Na4 also attacks the bishop with knight safe! But bishop can play... c5 attacked by knight a4; bishop must move; also bishop could take b2? Bxb2! Bc5xb2 grabbing pawn, attacked by? Kc1xb2! Bishop b2 attacked by king c1. So bishop moves. Na4 then bishop retreats, then Nxc5? No, knight can't catch. Hmm, Na4 keeps knight centralized less but attacks bishop. But Nd7 after Bc4+ is better. Even better: check Bb5! immediately: attacks c6, and c6 defended only by Bb7. And knight b6 attacked by Bc5 — Black responds Bxb6 2... no wait, Bc5xb6 taking knight! Bb5 Bxb6 loses knight for bishop. So must address the threat first. So: Bc4+ then. Which king move: Kf8 or Ke7? After Bc4+ Ke7, Nd7?? Kxd7. So instead Na8/Nc4... After Ke7, Nd5+! Forcing again: Kf8 (Ke8, Kd7? d7 attacked by knight? Nd5 attacks e7(check) and... king d7 — knight on d5, king d7 adjacent? d5-d7 not adjacent (d6 between). Kd6? attacked by Bd3? d3... no. Kd6 attacked by knight d5? adjacent—kings can't be adjacent to knight attacked square? King can't move to square attacked by knight: d5 knight attacks c7, e7, f6, f4, b4, b6, c3, e3. Not d6. Kd6 legal? Then knight... and bishop d3 attacks? d3-e4-f5, c4-b5. Kd6 then? Hmm. Nd5+ Kd6!? then Bb5+? cxd5?? pawn c6 takes d5! After Nd5+ Kd6, c6 pawn attacks d5 knight! So Nd5+ Kd6 cxd5 wins knight. Bad. So after Bc4+ Ke7: play Na4 attacking bishop? or Nd7 illegal-ish (Kxd7), Nc4?? Bxc4. Na4: bishop moves, fine. Or Bd... hmm. After Bc4+ Ke7, Bxc6!? Bishop c4 to... c4-c6 not diagonal. OK. Simpler to just check if there's a forced win. Position is winning anyway. Play Bc4+. Response Kf8: then Nd7 or Na4 attacking bishop. Kf8 then Nd7 attacks c5, bishop retreats, then Ne5 forking c6/g6... good. Response Kg8: Nd5 then Nxc7?? none. Na4 attacks c5. Then bishop moves, then Bxc6? no. Na4 then... Bxc6?? bishop c4 can't take c6. Hmm what about after Bc4+ Kg8, Nd5 Bxd5?? bishop c5 covers d4 not d5. Bb7 covers d5? blocked by c6. So Nd5 safe, attacks c7/e7/f6. Then Nf6? attacks g8 king... Actually plan: Nf6! then Nxh7? h7 empty. Ng4, Ne7 forking? Nd5-f6 attacks h7,g8,e8... then Nh7 forking? Ng8... whatever, winning endgame: up bishop+knight+5 pawns. Just play Bc4+ and follow up by saving knight. Check legality: Bd3 to c4 — d3-c4 diagonal, empty. Yes, gives check to Kf7 via c4-d5-e6-f7. Legal. Actually also consider Kd1/Kb1 escaping? Not needed. One more check: is Bc4+ met by ...Bd6 blocking? c5 bishop can block on d6/e7? Bd6 blocks check. Then Bxd6? No—Bc4xd6: c4-d5-e6-f7 diagonal; d6 not on it. Block on e6/d5/f7... bishop c5 to d6 blocks. Then knight b6 still attacked by Bb7? No—Bb7 attacks? b7-c6 blocked... what attacked Nb6 originally: Bc5 (a5-b6? c5-b6 yes diagonal). Bd6 no longer attacks b6. So Bc4+ Bd6, knight safe! Then Rg1? or push h4, g4. Even better. Also Bc4+ Bd6, then Bxc6? no. Then Nb6 threatens? Nd7 eventually. Great, Bc4+ is strong.

Checking the position: Black's bishop on c5 just attacked my knight on b6, but I have a tempo-gaining check first — the bishop sortie to c4 hits the f7 king, and after ...Bd6 blocks (or the king moves), my knight is either safe or I get another free move.

Bc4+d3 → c4

Check please! Your bishop wanted my knight's head — let's see if it can multitask while I cash in.

GLM 5.3 Flash High· move 25…

I'm in check from Bc4. Legal moves: Ke8, Kf8, Kg6, Kf6, Ke7. Black king f7. Also... can I block? Bishop on c4 checks along diagonal c4-d5-e6-f7. Block on d5 or e6. I have Bb7... Bb7 to d5? b7-d5 diagonal: c6 pawn is in the way. Bc5 to e3/d4/b4... can't reach d5 or e6. Pawn c6-c5? No, block on d5/e6 with pawn? c6 can't. So king moves. Also, Bc5 was attacking Nb6. If I move king, does bishop defend? Bc5 attacks b6? c5-b6 yes diagonal. But Nb6 could be defended... Bc4 attacks... After Kf6 or Kg6? Wait, Kf6 — is that attacked? Bc4 covers... c4-d5-e6-f7. Kf6 not attacked. Kg6 — attacked? Bc4 diagonal goes to h7, not g6. Kg6 could be met by... nothing immediate. Consider Kg6 attacking h-pawn? Actually White has Bc4 and Rh1. Kg6 attacks... nothing really. Kf6 attacks e5? No pawns there. Down 9 points (rook for... actually down a rook? White 17 vs Black 8: White has R+B+N+4P = 5+3+3+4=15+2 = 17? pieces listed: Rh1(5), Bc4(3), Nb6(3), 7 pawns? a2,b2,c2,f2,g2,h2 = 6 pawns... 5+3+3+6=17. Black: 2B(6)+g7+c6=8. So down rook and pawn effectively. Endgame: R+B+N+6P vs 2B+2P. Very lost but let's just pick best move. Kg6 may allow Rh1 checks later? Actually with king on g6, Rh1-g1+ ideas. Kf6 or Ke7. Bb7 may hang? Bc4 doesn't attack b7. Nb6 attacks? b6 knight attacks c4, a4, d5, d7, a8, c8 — not b7. Best maybe Ke7 keeping king near. Or Kg6 heading to attack pawns? White pawns f2,g2,h2 — Kg6 could attack h2? Not yet. Kf6 attacks g5... eh. Nb6 could threaten c4 bishop? Nb6-c4? No, knight on b6 attacks c4? b6 to c4: not a knight move (b6->c4 is not legal; knight from b6: a4,c4? b6 to c4 = 1 file,2 ranks = yes! c4 is a knight move from b6 (b to c =1, 6 to 4=2). Yes Nc4 possible? c4 has bishop — Nxc4! But knight is on b6, Nxc4 would capture the bishop. But is Nxc4 legal now? I'm in check, so no. After king moves, can I play Nxc4 next? If Kf6, White might move bishop or defend. Bishop defended by nothing... Actually Nxc4 would win bishop. But White will just move Bc4 away or... if Kf6, does f6 affect? White could play Bd5 or Bb5 etc. Or Rh1 defense? Bishop is defended by? nothing. So after Kf6, threat Nxc4. White must respond. Perhaps Kf6 is decent: also brings king to attack pawns. Alternatively Ke7 aiming... Kf6 vs Ke7. After Kf6, White Bd5/Bb3/Bb5... If Bb3, Nxc4? bishop on b3, knight from b6 can't reach b3. If Bd5 then Bxd5? c5xd5? No, c5 to d5 not diagonal. cxd5! c6 pawn takes d5. Hmm. Kf6 seems active. Let's go Kf6.

Position: White up huge material. Need to pick strong move. Black threatens ...BxNb6? Actually Bb7 attacks Nb6 (b7-b6). Yes Bb7 attacks knight on b6. Also Bc5 pins? Bc5 attacks... g1 diagonal: c5-d4-e3-f2... attacks f2 pawn, and Rh1? No. Nd7+ forks? Nd7+ attacks... from d7: attacks f6 (king), and b8, f8, b6? d7 knight attacks b6? No, b6 is adjacent to d7? Knight on d7 attacks b8, b6, c5, e5, f6, f8. Wait knight on d7 attacks c5 (bishop) and f6 (king). So Nd7+ forks king and Bc5! That wins the bishop... but then Bb7 takes b6 knight. Trade N for B, still up tons. Better: Na4 protects? No, knight moves away from attack and attacks c5. Na4 attacks c5 bishop. Then Bxb6? Then Nxc5. Same. Alternatively Be6+ first? Be6+ check from e6, king f6... Be6 attacks king; king can take? Kf6 attacks e6, defended by? Nb6 doesn't defend e6. Bc5 doesn't. King can capture? Be6 - is e6 defended by White? No. So Be6+ Kxe6 loses bishop. Nd7+ K moves, then Nxc5 Bxb6 — wins bishop for knight, even trade. Then White has B + R + 5 pawns vs 2 pawns. Winning. Or Na4 attacks c5: bishop must move or Bxb6 Nxc5. Same result. Or simply move knight with attack... Na8? Nd5+ forks? Nd5+ from d5 attacks f6 (king), c7, b6? No. Nd5+ attacks... d5 knight: b6, b4, c3, e3, f4, f6, c7, e7. Attacks king f6, but not bishop. After king moves, knight can go... Nb6 attacked by Bb7 anyway. Nd7+ best: fork king and Bc5. If Kf6 moves (to g5? g6? e7? f5?), then Nxc5 (bishop captured), but Bxb6 takes knight. Net: wins Bc5, loses Nb6, Bb7 stays. Even material trade N for B. Then Rh1... Actually after Nd7+ K somewhere, Nxc5 and if Bxb6, White has R+B+5P vs B+2P. Easily winning. Alternative: Bf7 threatening Bg8? No. Could we do better: defend knight while keeping attack? Nd7+ forks, best. Or Nd5+ — after king move, knight attacked by...? Nd5+ Kf5? Then Bb7xb6 anyway. Nd7+ is cleanest. Check legal king replies after Nd7+: king on f6. Nd7 attacks f6. King moves: Kf5? attacked by? Bc4 covers... Bc4 on c4: covers b5, a6, d5, e6, f7, g8, b3, d3, e2, f1. Kf5: attacked by... not by Bc4. Kf5 legal? Nd7 doesn't attack f5. Pawn? no. Kf5 legal. Kg5, Ke7, Ke6? Ke6 attacked by Bc4 (c4-d5-e6). Kg6, Kg7? g7 has pawn. Kf7 attacked by Bc4? c4-f7 diagonal yes. So king: f5, g5, g6, e7, e5? e5 attacked by? nothing... anyway. After Nxc5, bishop on c5 captured. Then Bxb6 recaptures knight. Fine. Or if black doesn't take knight, White is just up a bishop and can retreat/defend knight later. Play Nd7+.

Check from Nd7. Legal moves: Ke7, Kg6, Kg5, Kf5. Kg6 seems safest? Kg5 allows Rh5+ maybe. Kg6: then Nd7 forked with... knight on d7 attacks c5 bishop and g8? Let's think: after Kg6, knight d7 is attacked by nothing. Bc5 attacked by knight, and Bc4 pins? Bc4 attacks c5 along diagonal? c4-c5 yes, adjacent. So Bc5 is defended by Bc4? Actually bishop c4 protects c5. Knight attacks c5. Also Ne5+ possible forking? After Kg6, white could play Ne5+ (knight d7 to e5 check) forking king g6 and c4... Ne5+ hits Kg6 and c4 bishop and g... Ne5+ forking king and Bc4! Then after king moves, Nxc4. Alternatively Kg5: Ne3+ forks? Nd7-e5+? Kg5, Ne5+? No, from d7 knight can't go e5 with check to g5? Ne5 attacks g4, f3, c4, c6, d3, f7, d7, g6. Not g5. But Kg5, white Ne3+ check attacks g... Ne3 attacks g4, f5, d5, c2, c4, b1, d1, f1, g2. No. Kg5: Rh5+? Rxh5+ Kxh5. Rook h1 to h5 check. Kxh5 wins rook? g5 king can capture h5. But then white... after Kxh5 white has nothing. Wait, that gives black a rook! Kg5?? Rxh5+ Kxh5 — is h5 defended? White pieces: Bc4, Nd7, pawns. Bc4 doesn't hit h5? No. So Kg5 Rxh5+ Kxh5 wins the rook. But wait, Kg5 — is g5 attacked? By Bc4? No. By Nd7? Knight d7 attacks c5, b6, b8, f8, e5, f6. No. So Kg5 is legal, and if Rxh5 then Kxh5. But white might not take. Kg6: attacked by Nd7? No. Rh6+? Rxh6+ Kxh6 also wins rook! Wait king g6, rook h1-h6 check, Kxh6. Is h6 defended? Bc4 diagonal c4-d5-e6-f7 — no. So both Kg5 and Kg6 seem to win the rook if attacked. But hold on — Kg6, then Ne5+ forks king g6 and bishop c4, and also knight attacks c6 pawn... After Kf6? no. Let's evaluate Kg6: threat is Ne5+ forking Kg6 and Bc4, winning the bishop. Then black's bishop c5 is attacked by Nd7? After Kg6, knight d7xc5 possible: Nxc5 attacks... wait Bc4 defends c5. Nd7xc5 then Bxc5. Bad. Kg5: white plays Ne3+? Not check. Nd7-f6? No check. Kg5 threats: Rh5+ Kxh5. White could instead play Nf6 attacking h5... Kg5, then Ne5 (no check)? Kg5... actually can white play h4+? h2-h4+ check from pawn to king g5? Pawn on h4 attacks g5, yes! Kg5, h4+! Kxh4?? h4 defended by Rh1! So h4+ Kxh4?? illegal — actually king can't capture defended pawn. So Kg5 h4+ and king must go back or... Kg5 in check from h4 pawn; moves: Kg6 (h4 pawn doesn't attack g6), Kh6?? attacked by Rh1. Kg6, then Ne5+? No check to g6? Ne5 attacks g6 yes! Knight e5 attacks g6, g4, f3, d3, c4, c6, d7, f7. So Kg6 Ne5+ fork again. Similarly Kg6 directly: Ne5+ Kg... king on g6 in check from Ne5; king moves: Kf5, Kh5, Kf7, Kg7, Kh6?? Ne5 covers... Ne5 attacks f7, g6, g4... Kh6 attacked by Rh1! Kf5 attacked by? Ne5 no, Bc4 no... Kf5, then Nxc4. So black loses bishop. Kg6 loses bishop c4 via fork, and bishop c5 attacked by knight. Hmm what about Kg6 immediately Ne5+ Kf5 Nxc4, then black plays Bxf2+!? Kg6 after Nxc4: black Bc5 and g7 pawn, white up but black might get counterplay? Down 9 material, hopeless anyway. Kg5 option: h4+! Kxh4 illegal (Rh1). After h4+ king must move: Kg6 Ne5+ again, or... from g5, attacked squares: h4 pawn attacks g5, h4 pawn can be captured? No. g5 king moves: Kg6, Kh6(Rh1), f4? Kg5 to f4: attacked by? Nd7 no, Bc4 no... wait Kg5 to f4 — but in check from h4, f4 not attacked by pawn h4? No. f4 attacked by Rh1? No. So Kf4. Then Ne5?? no... hmm. Alternatively Kg6, white plays Rh6+!? Kxh6 then white... Rh6+ Kxh6? Wait does Bc4 defend h6? No. So Kxh6 wins rook. After Kg6 Rh6+ Kxh6, white loses rook; black still down but has K+2B vs K+B+N+pawns? Let's count: after Kxh6: White K, Bc4, Nd7, pawns a2 b2 c2 f2 g2 h2 = 3+3+6... wait material originally 17 vs 8. After trade: black loses nothing, white loses rook(5): 12 vs 8. Black K, Bb7, Bc5, pawns c6, g7. White B, N, 6 pawns. Still lost for black but rook is nice. But white wouldn't play Rh6+; white plays Ne5+ winning bishop c4. Then black is worse: down bishop. Alternatively after Kg6 Ne5+, can black counter with... it's check, must move king. Kf5 then Nxc4 then black Bxf2? c5 bishop takes f2: Bxf2 attacked... Bxf2 threatening? White king c1, Bf2 attacks e1, g1, e3, d4... check? Bf2+ no, king c1 not on diagonal from f2 (e1, g1 directions). Not check. Alternatively Kg5 h4+!? — wait, could black respond... it's check from pawn; Kxh4 illegal due Rh1. So black loses tempo but gains pawn? No, can't take. Hmm, is there Kg6 then Ne5+ Kf5, Nxc4, then black Bxf2+? Not check. Then black has Bc5, Bb7, c6, g7 vs N, 6 pawns, B... white Bc4 was captured? No — Ne5+ forked king and Bc4, so Nxc4 wins Bc4. White then up: B, N, 6 pawns vs 2 B, 2 pawns. Totally lost. What about Kf5!? Immediate: Kf5 attacked by? Bc4-d5? No, c4 diagonal: b5, a6, d5, e6, f7, g8. Not f5. Nd7? attacks c5, b6, b8, e5, f8, f6. Not f5. Kf5 legal. Then black threatens...? Black bishops aim at... hmm Kf5 attacks nothing immediately. White plays Nxc5 (bishop c5 undefended? Bc4 defends c5! c4-d5? No, c4 to c5 is not diagonal. Wait Bc4 on c4; c5 is not on a diagonal from c4. Diagonals from c4: b3,a2 / b5,a6 / d3,e2,f1 / d5,e6,f7,g8. c5 is orthogonally adjacent. So Bc4 does NOT defend c5!). Let me recheck: earlier I said Bc4 protects c5 — wrong! c4 to c5 is vertical. So Bc5 is defended by nothing except king. So knight d7 attacks c5 bishop, undefended. Black in check must move; if Kg6, Nxc5? No — knight d7 to c5 is legal (d7-c5). After Kg6, Nxc5 and knight is attacked by? Bb7? b7 diagonal: a8, c8, c6, d5, e4, f3, g2, h1. Not c5. So Nxc5 just wins bishop. Kg6 loses c5 bishop without fork. Hmm so the real question: which move saves the c5 bishop or gets best outcome. Check from d7 knight: attacks c5, f6, b6, b8, e5, f8. King on f6 in check. Option Kf5: defends? Then Nd7xc5 wins bishop anyway (bishop undefended). Unless after Kf5 black threatens Bb6? Hmm. Wait, actually black could counterattack: after any king move, Bc5 attacked. What about Bc5xf2+! Now, in check — can't. Let me consider Kg6 and white's best: Ne5+ (fork Kg6/Bc4) — also Nxc5. Ne5+ better. Kg6 Ne5+ Kf5 (or Kh5/Kf7/Kg7) Nxc4. Black down more. Alternative: maybe instead of saving bishop, capture something? No captures available in check. What about Kf5!? then Ne5?? not... hmm. Kf5 attacked by Bc4? No. After Kf5, white Nd7xc5 then black... Bxf2+!? Kf5 allows... wait after Nxc5, black plays Bxf2+? Is it check? Bf2+ — king c1: f2 to c1? No. Bb6? Hmm. Actually wait — after Kf5, does black threaten Bxf2+? King c1: Bc5-d4-e3-f2: no check. Bb7... Bb4+? b7-a6 or b7-c6... b7 to... c8, a8, d5, e4, f3, g2+? g2 pawn there. Bb7 can't check. Alternatively Kf5 threatening g5 push? Not really. Realistically black is lost. Pick move that's most resilient: Kg6 seems to threaten ...Rh6+? No wait — Kg6 attacks the rook? Kg6 doesn't attack h1 rook. Hmm, but after Kg6, if white grabs bishop with Nxc5, black plays... g5? Rh5+ ideas: Kg6 then black threatens nothing immediate. Compare Kg5: after Kg5, white h4+! Kf4 (or Kg6). Kg5 h4+ Kf4, then Ne5+!? Knight d7-e5+ check from e5 to f4? Ne5 attacks f3, g4, d3, c4, c6, d7, f7, g6. Not f4. Not check. Then Nxc5 anyway. Kg5 h4+ Kf4 Nxc5 — knight attacked by? King f4? No (f4 to c5 no). Then black plays Be3!? Bc5-e3 check? e3: king c1? No. Bb4? Not check. Hmm, but Kg5 h4+ Kf4 Ne5 (not check) threatening Nxc4 and... king f4 attacks e5! Kf4xe5?? e5 defended by? Nothing. Wait after h4+ Kf4, knight is on d7 still. Nd7-e5+ not check but Kxe5 possible? No, knight moves first. Hmm, actually after Kg5 h4+ Kf4, then white Ne5 (threatening Nxc4 and Ng6/Nd3), Kxe5! Is e5 defended? By nothing white: Bc4 covers e2... no. So Kxe5 wins knight?? But wait, is it white to move playing Ne5 moving into Kxe5 — no, white wouldn't. Alternatively Kg5 h4+ Kg6 Ne5+ fork again. Best practical: Kg6 seems more natural; after Kg6 Ne5+ Kf5 Nxc4 black has Bc5, and Bxf2 ideas. Or after Kg6, Rh6+?? Kxh6 if white errs. Actually wait — reconsider Kg5 vs Kg6 regarding h4: after Kg5 h4+ Kf4!, white h5? threatening h6... hmm. Another idea: Kg6 and if Ne5+ then Kf5! attacked by Ne5? No. Nxc4 then black Bxf2+? still not check... f2-e1-d0... Bc5... hmm Bc5-b4+? No check. Let me also check Kf5 more: after Kf5 Nxc5, does black have Bxf2+? No check. Ke4+? No. Hmm, what about Kg6 Ne5+ Kh5!? Kh5 attacked by Rh1? No, Rh1 attacks h-file up to... rook h1 attacks h2 pawn (blocked by own pawn h2). So h-file blocked. Kh5 attacked by Ne5? No. Bc4? No. Then Nxc4 and black... g5!? threatening? Kg5? Black king h5, pawn g7-g5 then g4? Not much. Honestly the position is winning for white regardless. Engine choice: Kg6 or Kf5. Consider Kf5 directly avoids the Ne5 fork: after Kf5, Ne5 is not check and Kxe5? e5 defended by? No. So Kf5! prevents the fork. Then white Nxc5 (wins bishop) or Bb5/Bd3 etc. After Kf5 Nxc5, black Bxf2+? no. Black's best: Bb6/Bd4? Bc5 moves... black has Bb7, Bc5, pawns c6 g7, Kf5. White Bc4+! maybe: after Kf5 Nxc5, Bc4... wait Bc4 already; Bd5+? no check from c4 to f5? c4-d5-e6-f7. Not f5. But Bb5+!? b5-a4... b5 to f5? No. Bc4 gives check along? No. Hmm wait, actually Kf5: does Bc4 attack f5? No. Nd7 attacks f6, f8, e5, c5, b6, b8 — not f5. OK. But after Kf5, white Ne5! attacks g4+?? Ne5 then Kxe5? No wait knight going to e5 — is e5 defended? Bc4-d5-e6... no. Nd7-e5+? Is it check to f5? Ne5 attacks f3, g4, g6, f7, d7, c6, d3, c4. Not f5. So Ne5 not check but attacks... nothing much, and Kxe5 possible? e5 adjacent to f5, yes! But if it's white's move, knight lands safely only if defended — it's not, so black just plays Kxe5 next if knight goes there — but knight wouldn't be captured immediately... actually white moves Ne5, then black Kxe5 wins the knight? Wait Kf5, white plays Ne5 — is that legal? Yes, e5 empty, not check. Then black Kxe5! since e5 defended by nothing. So knight can't come to e5. So Kf5 seems best: saves from fork, keeps bishop... but bishop c5 still hangs to Nxc5. After Kf5 Nxc5, black could try Bxf2+? not check. Black material: Kf5, Bb7, g7, c6 vs white Bc4, 6 pawns, K. Lost but longest resistance. Alternatively after Kf5, white might play g4+! Kg... f5 king: g4 pawn push checks? Pawn g4 attacks f5, yes check! Kf5... moves: e4?? attacked? Bc4! e4 attacked by Bc4. Ke6, Kg6, Ke5?? no... Kf5 in check from g4: Kg6, Ke6 (c4-e6 yes attacked? c4-d5-e6 diagonal, yes attacked), Kf6, Kg4?? no. Ke5, Kg6. Hmm Ke5/Kf6/Kg6, then pawn takes stuff... g4-g5, h4, etc. Pawns roll. Still lost. Compare Kg6: Ne5+ Kf5 (only non-losing square? Kh5, Kf7, Kg7, Kf5). Kh5!? then Nxc4 and black has... hmm Kh5 attacked by nothing; but then white g4+?? from g2-g4 check to h5? g4 attacks f5 and h5, yes check! King h5: Kh4?? attacked by Rh1. Kh6, Kxg4?? g4 defended by? No! h5 captures g4: adjacent. g4 defended by? h3? No pawn there... Rh1 no. Bc4 no. Kxg4! wins pawn. So after Kg6 Ne5+ Kh5 Nxc4 g4+! Kxg4 black gets pawn back. Hmm interesting. But also after Kh5, Nxc4, white Rh5+?? no rook h1-h5: h2 pawn blocks. OK. Ugh, let's just evaluate simply: choose Kf5. Actually wait — one more: after Kf5, black threatens Bxf2+!? No. Threatens g5!? Alternatively does Kf5 allow Bc4-b5+? No. Also consider Kg6 then Nxc5 (greedy) Bxf2+!? not check... c5-f2 diagonal: d4, e3, f2. King c1 not check. Also Kg6 Rh6+!? Kxh6 — white wouldn't. Between Kf5 and Kg6: Kf5 avoids Ne5 fork entirely since e5 adjacent. I'll play Kf5. But wait — is f5 attacked by anything? Confirmed no. But after Kf5, is black threatening to trap/hunt the knight? Kf5 attacks e5, f4... Kf5 then white must deal with Nxc5 threat being met... After Kf5 Nxc5, knight c5 attacked by? No. Hmm, but black's Kf5 was to approach e5: after Nxc5, black Bxf2! for real? c5-d4-e3-f2 — Bf2, is it check? No. But threatens Be1? No. What about after Kf5 Nxc5, black plays Bb6!? hmm. Actually, let me reconsider: maybe after Kf5, instead of Nxc5, white's best is Bb5/Bd3 consolidating, and black gets Bc5xf2 at some point? Bc5xf2+ never check while king on c1? f2-c1? No. King on b1? Bf2+... no. Also after Kf5, black threatens Ke4!? no. Fine, Kf5 it is. Actually, hmm, wait: after Kf5, white Nd7-c5 — actually black then plays Bxc5?? No, black bishop is ON c5. Knight captures bishop on c5. After Nxc5, black's remaining: Bb7, g7, c6. Then black Bxf2! attacking Rh1? Bf2 hits g1, e1... and Rxf2?? No — Bf2 attacks h4, g1, e1, d4, c5... rook h1 not attacked. But Bf2 then Bxe1?? Not useful. OK: Kf5. Actually one more check — after Kf5, can white play Ne5 forking?? Ne5 not check, and it would hang to Kxe5? But if white plays Bb3 first defending e5? Bc4-b3 defends? b3-c4-d5... b3 to e5? No. Bd5!? Bc4-d5 defends e6... defends e5? No. Be2 defends f3... e2 defends d3,c4,f3,g4,f1,d1... no. Defending e5: Bc4? no. So e5 always poison. Good. Also after Kf5, g4+ Kf6/Kg6/Ke5? e5 not attacked? g4 pawn attacks f5, h5. Ke5 legal? Bc4-e2... does anything attack e5? Nd7... after check resolved — wait it's check from g4 pawn: Kf5 must move: Kg6, Ke6 (attacked by Bc4), Kf6. Kg6 or Kf6, then h4, g5 rolling. If Kf6, g5+!? f6 king: pawn g5 attacks f6, check! Kf7... it's a pawn storm. Meh, lost anyway. Actually, alternatively Kg6 avoiding pawn storms longer. Let me think which an engine would pick... Kg6: white h4! then Kg5?? h4 attacks g5. Kg6 h4 then g5+?? no wait black to move after h4: black g7-g5!? hxg5? h4xg5? No, h4 captures g5? Yes pawn takes pawn on g5. Hmm. I'll go Kg6 — keeps king safer from pawn checks, and after Ne5+ Kf5 Nxc4, similar. Or after Kg6, white h4 then black... Nxc5 happens anyway. Honestly both lose. Engine-wise let me think deeper: after Kg6, white Ne5+! Kf5 (Kh5 Nxc4 g4+! Kxg4 recovers pawn; but then Kh5... after Kxg4 white Bc8?? hmm black Bb7 controls... white Bd5?). Let me pick line: Kg6 Ne5+ Kh5! Nxc4 g4+ Kxg4 — black king active, white K, pawns a2b2c2 f2 g2(cap'd? no wait) — hold on, after Kxg4, white pawns: a2 b2 c2 f2 h2 (g4 captured). Black: Bb7, Bc5, c6, g7. White B?? white's c4 bishop was captured. White has only pawns + king. Black has 2 bishops + 2 pawns! That's WINNING for black!! Check: Kg6 Ne5+ Kh5 — is Kh5 legal? Squares around: g4, h4, g5, h6, g6(from). Attacked by: Rh1? blocked by h2 pawn — yes blocked, h3/h4 not attacked by rook... wait rook attacks h2 (own pawn) and stops. So h4 free but king going h5. Ne5 attacks g4, g6, f7, f3, d3, c4, c6, d7 — not h5. Bc4 attacks? Not h5. Pawn g2 attacks f3, h3 — not h5. Legal! Then Nxc4 (fork exploited; could also be other move but white wants bishop c4... wait the fork: Ne5+ attacks Kg6... king moved to h5, and Ne5 attacked Bc4. White plays Nxc4 winning bishop c4). Then black g7-g4+!? check to Kh5? pawn g4 attacks f5 and h5 — check! Kxg4: g4 defended by? f3? nothing on f3. h3? empty. Rook h1? attacks h2 pawn only. Kxg4 legal. So black ends: Bb7, Bc5, pawns c6, g7, Kg4 vs White: Kc1, pawns a2, b2, c2, f2, h2, Rh1. Two bishops vs rook and 5 pawns vs 3... wait count: white Rh1(5) + pawns 5 = 10; black 2 bishops (6) + 2 pawns (2) = 8. White still up 2. Hmm not winning. But black king active on g4, white king c1 far, black bishops strong. Rook endgame-ish... Black might draw or even win with active play? Two bishops + connected-ish pawns vs rook+5 pawns, black king invading g4, white king scattered pawns a2b2c2 f2 h2 — rook must defend. Actually this could be quite good for black! But white might not play Nxc4. After Kg6 Ne5+ Kh5, white alternatives: Rh5+?? blocked no. g4+!? immediately (before Nxc4): pawn g2-g4+ check Kh5, then Nxc4 wait — g4 blocks nothing... after g4+ Kh6!? or Kxg4? g4 defended by? Nothing (Rh1 blocked by h2). Kxg4! and knight e5 hangs? Knight e5 attacked by Kxg4-king? No, g4 to e5 not adjacent. Then knight still forks c4? After Kxg4, black threatens Kxe5?? e5 defended? No... but knight there. Actually black just wins: Kxg4 then next Nxc4 or Kxe5. Hmm wait after Kg6 Ne5+ Kh5, white could play Ng4+!? knight e5-g4+ check to h5! Ng4 attacks h6, f6, e5, e3, f2, h2. h5? Knight g4 attacks h6, f6, e3, e5, f2, h2, i3, i5. Not h5. Not check. OK. Or Kg6 Ne5+ Kh5 Bxf7?? irrelevant. Or white declines: Kg6 Ne5+ Kh5, white Ng6!? no. White best is Nxc4, then g4+ Kxg4. Position: black Kg4, Bb7, Bc5, c6, g7 vs K, R, pawns a2 b2 c2 f2 h2. Black slightly worse but very playable, maybe drawable. Alternatively Kg6 Ne5+ Kf5 Nxc4 — then black Ke4!? hits nothing... worse than Kh5 line? Kh5 line gets pawn. Also Kg6 h4 (instead of Ne5+): black g5!? hxg5?? no wait, black plays g7-g5, hxg5 then... or black Kh6?? Rh1 pins... Actually after Kg6 h4, black Nxc5? Knight takes bishop. Or black g5 attacking h4: if hxg5, then... hmm. Now check Kg5 line: Kg5 h4+! Kf4 (Kxh4 illegal). Then Ne5?? no — Nd7-e5+ not check to f4. But Nd7-f6+!? no. Nd7xc5 wins bishop: after Kg5 h4+ Kf4 Nxc5, black Bxf2!? c5-f2: Bf2 attacked by Rh1? Rook h1 attacks f1 along rank! Rh1-f1, f2 bishop: rook attacks f1, and f2? Rook on h1, going left: g1, f1, e1 — f2 not on rank 1. Bishop f2 attacked by Rh1? No. Bf2 threatens Rxf2?? nothing. Black Kg5 line: h4+ forced Kf4/Kg6/Kh6(illegal? Rh1 attacks h6? h-file: h2 pawn blocks, so h6 NOT attacked by rook! Wait pawn h2 blocks the rook on h1 from seeing h6. So Kh6 is legal after h4+? h4 pawn attacks g5 (where king is) and h5... wait pawn on h4 (white) attacks g5 and... white pawn attacks diagonally forward: g5. Not h5/h6. King on g5 in check from pawn h4. Kh6: attacked by Rh1? h2 white pawn in between — blocked. So Kh6 legal! Then king h6, pawn h4... Kxh5?? no pawn... hmm. This is getting deep. Given Kg6 Ne5+ Kh5 g4+ Kxg4 line yields decent outcome, and also Kg6 gives Rh6+? Kxh6 if white blunders, I'll play Kg6. Wait — one more consideration: after Kg6, is there Rh6+!? really: Rook h1 to h6 — path h2 occupied by white pawn! Rook can't pass h2. So Rh6 impossible. Good, h-file permanently blocked by h2 pawn. And g2 pawn blocks g-file for nothing. So Kg6: white's real tries: h4 (then Kg5?? no, h4 attacks g5; black plays g5!? or Nxc5 or Bxf2... after Kg6 h4, black Nxc5 wins bishop, knight attacked by? No. Then black fine-ish) or Ne5+ Kh5! g4+ Kxg4 Nxc4 (order: white plays Nxc4 first, then g4+ Kxg4 — same result) — ending as computed. Actually wait, in line Kg6 Ne5+ Kh5 g4+! — is g4+ legal, does anything block? No. Kxg4 then white Bxf7?? whatever. But also after Kg6 Ne5+ Kh5, white might realize and play Kg2! guarding... doesn't stop g4+. Also after Kxg4, white Bc4 gone already (Nxc4). White could try f4+!? pawn f2-f4+ check to Kg4? f4 pawn attacks e5, g5 — not g4. No check. Black king g4 vs white Rh1: black threats Bc5-d4/e3 hitting f2, Bb7 hitting g2? Bb7-g2: blocked by... b7-c6? Black's own c6 pawn on c6 blocks! Bb7 diagonal toward g2: c6 occupied by own pawn. Hmm. Bc5-e3 attacks f2 and... Bc5-e3-f2-g1. And Be3 threatens Rxe3?? no. Black can also push c5, g5, h5 etc. White defense: Kg2 heading to... Rh4+? No. This looks drawish/unclear — much better than other moves. Also alternatively after Kg6 Ne5+ Kh5, black might even prefer Kh6!? no, g4+ idea is with Kh5. Decision: Kg6. Wait, but also consider: after Kg6 Ne5+ Kh5 — is there Ng4+ ... no check. Rh5+?? no. g4+ forced check response Kxg4. But hold on — after g4+, could white have Nf6+ tricks? Not relevant; it's black's move after g4+? Sequence: 26...Kg6 27.Ne5+ Kh5 28.Nxc4 g4+ (black's move 28...g4+? move numbers: 26...Kg6 27.Ne5+ Kh5 28.Nxc4 g4+ 29.Kxg4). Yes fine. But actually, is 27...Kh5 better than 27...Kf5/Kf7? Kh5 nets the g4 pawn. Good. Also double-check 26...Kg6 legality: g6 attacked by Ne5? Knight currently d7 — attacks f8,f6,e5,c5,b6,b8. g6 safe. Bc4? No. pawns f2/h2? No. Legal ✓. Go with Kg6.

Down heavy material, but there's a path: I'll step to g6, eyeing the h-file (blocked by White's own h2 pawn) and setting up the king hunt.

Position: White up a rook+ bishop? Material White 17 vs Black 8 — White up knight and bishop and pawn... Actually rook h1 vs nothing. Black has 2 bishops, pawn. White has R, B, N, 5 pawns. Knight d7 currently attacked by bishop b7? b7 bishop attacks d7? b7-c6... b7 diagonal: a8, c6, d5, e4, f3, g2. So no. Bishop c5 attacks d4, e3, f2! Bxc4? No. c5 bishop attacks d6, e7, f8, b4, a3, d4, e3, f2. f2 is defended by... nothing? Pawns: f2 pawn is on f2, attacked by bishop c5 via d4-e3-f2. f2 defended by g2? g2 doesn't defend f2. King c1 doesn't. So f2 hangs? Well, bishop can't take f2 next move safely. Black threatens Bxg2? c5 bishop can't reach g2. Bb7 can attack g2 via f3? b7-f3-g2: yes Bxf3 no... bishop b7 on light squares: b7, c6, d5, e4, f3, g2, h1. Rh1 is on h1. If bishop goes to f3, it attacks h1 rook? No, f3-g2 pawn blocks. Black could play Bf3 attacking g2. Best move: Ne5+ forking? Ne5+ checks king g6? e5 attacks g6 yes. Then knight on e5 attacks c6 pawn too. King moves: Kg5? attacked by... Ne5 covers f7, g6, f3, d3, c4, c6, d7. King g6 must move: Kh6? attacked by nothing? Rh1... h-file: Kh6 h6 attacked by Rh1? Rook h1 on h-file, h2 pawn blocks. So h-file blocked. Kg5: attacked by Ne5? e5 attacks f7,g6,d7,c6,c4,d3,f3 — not g5. Kg5 possible? g5 attacked by anything? No. But then Ne5xc6 forks? Ne5 then attacks c6 pawn and bishop b7? c6 defended by Bb7. Maybe better: Nf8+ forking g7? No wait, Nf8+ — knight d7 to f8, check to Kg6? f8 attacks g6 yes, and h7... also attacks g6. King moves Kg5 or Kh5? h5: attacked by Rh1? h-file blocked by h2 pawn. Kh5 then... Nf8 doesn't fork. Then Nxg7 no wait g7 pawn defended by king? Kh5 king doesn't defend g7. Nf8 threatens g7? f8 knight attacks g6, h7, e6, d7. Not g7. Hmm. Nb8 threatening? Nb8 attacks c6 pawn: forks? Nb8 then Nxc6 winning pawn, king can't defend; but Bc5... Nb8 attacks d7, a6, c6. Then Nxc6 Bxc6? Bb7xc6 yes. So Nb8 doesn't win pawn... c6 pawn defended by Bb7. Nxc5 wins bishop! Knight d7 takes c5. Is c5 defended? King g6 doesn't. b-pawn gone. d-pawn gone. d4? nothing. So Nxc5 just wins a piece! Check: any recapture? Bb7 doesn't attack c5 (different color). So Nxc5 Bxg2 or something — just win bishop. That's clearly best. After Nxc5, Black might play Bxf3? no. Black could take g2: Bxf3 no... Bb7 attacks g2 via f3? f3 is empty, so Bb7-g2 line: b7,c6? c6 pawn on c6 blocks! b7 to g2 goes through c6, d5, e4, f3 — c6 occupied by black's own pawn. So no attack on g2. Black might play Bc8 attacking knight? Nxc5 Bc8? Then knight escapes with tempo: Ne4, Nd7, or Nb3. Nd7 attacked by nothing. So Nxc5 wins a clean bishop. Move: Nxc5.

The c5 bishop is completely undefended — my knight's been staring at it the whole time. Free piece, thank you very much.

Position: Black Kg6, Bb7, pawns g7 c6. White Kc1, Rh1, Bc4, Nc5, pawns a2 b2 c2 f2 g2 h2. Black to move. White threatens? Bc4 is on c4, my bishop b7 vs Bc4 opposite diagonals. White has Rh1 which may come to h-file? h1 rook — Rh3 hitting h7? My king g6. I'm down hugely; play on. Options: Ba8 or Bc8 etc., or king moves. Actually my bishop b7 could go a8 eyeing h1? Ba8 attacks h1 along a8-h1 diagonal — but Bc4 blocks? a8-h1 diagonal: a8,b7,c6... no, c6 has pawn (my pawn). Ba8 attacks h1? Diagonal a8-h1 passes through b7,c6,d5,e4,f3,g2,h1. g2 has white pawn — so no. Bc8: attacks h3... no wait c8-h3 diagonal: d7,e6,f5,g4,h3. Nothing. White threats: Rh3+!? g6 king... Rh3 threat: h3-g3? Actually Rh1-h3 threatens Rh6#? Rh6+ Kxh6? no, king on g6, Rh6+ Kxh6 illegal (rook protected?). Rh6+ would be check, king can take if unprotected. Kxh6 — is h6 protected by anything? Bc4 doesn't reach. So Rh6+ Kxh6 fine. White threat maybe Nd7 or Be6 threatening? Bc4-e6+!? g6 king: Be6+ fxe6? no f-pawn is on f2. Be6+ is check to Kg6? e6-f5-g4 no. Be6 attacks g8... no, king g6: e6 to g4 diagonal, not g6. Bc4-d3+? attacks g6? d3-e4-f5-g6 yes. But currently Bc4 not giving check. Immediate threats: Nd7/Ne6 forking? Ne6 hits g7 pawn and c7. Or Nd3 forking. Best move for Black: maybe Kh6 keeping eye... or Ba6 attacking c4 bishop? Ba6 pins nothing. Bishop a6 attacks c4 bishop; if bishop moves, Ba6-g2? Not helpful. Actually does White have a mating threat? Probably not immediately. Best practical: Bc8 heading... or Kh7 solid, defending g7 indirectly? Kh7 attacks... king on h7, then Rh1-h3 ideas: Bc8 defends? White threat Be6+!? If Kh7, Bd3+ Kg8? hmm. Consider Kh6: then White Nd7? attacks? Knight c5-d7 hits b8/f8, not much. Rh3 threat? If Kh6, Rh3 no threat. Kh6 allows Bc4-d3+?? Kg6 fine? d3 attacks g6; Kg6 legal? after Kh6, Bd3+ Kh7? no check... d3-g6 diagonal check; king must move: Kh7 or Kf6? f6 attacked by? nothing — Kf6 fine. I think Kh7 is safest. Then White ideas: Be6? no. Nd7 then Ne5+? d7-e5, e5 attacks f7? King h7 — Ne5 doesn't check. Rh3 threat Rh7? not. Alternatively Bc8 to defend against Bd3+ ideas? Bc8 covers g4-h3 and e6... Bd3+ then Be6 blocks? Bc8-e6 interposes. Yes Bc8 guards e6. But Bd3+ Kg5!? then... eh. Kh7 seems clean. Quip: cocky.

Position: White up massively. Best move: Nxb7 wins the bishop. Check if it's safe: b7 bishop, knight on c5 takes it. After Nxb7, king can't take... nothing attacks. Or Bg8+!? — check. Let's evaluate quickly: Bg8+ Kg8?? No, after Bg8+ king h7, Bg8+ ... bishop from c4 to g8 attacks nothing; king h7 attacked by Bg8? Bg8 gives check along... bishop on g8 attacks h7 diagonally? g8-h7 yes, diagonal. King must respond. King can go Kg6? g8 bishop... after Bg8+ Kg6, then? Hmm. Simplest: Nxb7 wins a clean piece. But Bg8+ may fork/mate ideas? After Bg8+ Kg6, then Rh1... king escape via f5/g5? Actually Black king could be mated eventually. Let's just take the bishop: Nxb7. King h7 can't reach b7. Also knight on b7 attacks... then can swing. Yes, Nxb7. Is there mate faster? Bg8+ Kg6 then Rh1-g1+? no, rook g1+ is check? King on g6, rook g1 attacks g-file — king on g6 with g7 pawn... rook g1 attacks g7 pawn, king on g6 behind pawn. Not check. Bg8+ Kg6, then knight... Ne6 attacking? Let's just play Nxb7.

Position: Black Kh7, g7 pawn, c6 pawn. White Nb7, Bc4, Kc1, Rh1. Move 28... legal moves: g6, g5, Kh8, Kh6, Kg6, c5. Wait, c6 pawn can move c5. Also can it capture? Nothing on b5/d5. g7 pawn: g6, g5. King moves. Threats: White threats — Bc4 aims at f7... Nd6, Nc5 fork ideas? Nc5 threatens Nd7/Na5. Black is lost but plays for tricks. Rh1 is on board; back rank issues? White king on c1, knight on b7 blocks... Actually White's knight on b7 and bishop. Trick: ...c5 then ...c4 attacks bishop? Bc4 could move. Better: ...Kh6 heading to h4? Not really. Any tactics: ...g5 followed by ...g4, Kh6, h3? Not much. ...c5 attacks nothing. ...Kh6 to challenge? King can walk to b-file? ...c5, ...c4, ...Kg6-f5 etc. Actually there is a neat trick: ...c5 then if Bxc5?? nothing. Hmm. Maybe ...Kg6 to approach pawns? White pawns are all on second rank; they'll push. Black is completely lost; any move roughly equivalent. Maybe ...g5 followed by ...g4 and ...Kh6-g4?? King can go to f5, capture pawns after they advance. Play for fortitude: ...Kh6 aiming... or ...Kg6 then Kh5, g4!? Black king can head toward queenside: ...c5, ...Kg6, ...Kf5 to eat c2/b2 pawns? White bishop covers b5? Bc4 covers... Rh1 covers h-file and first rank. Realistic choice: 28...g5 (creating luft and preparing g4/h5 resistance) or 28...c5. I'll pick ...g5 to free the king's paths and make g4 possible. Actually ...Kh6 first, then g5. But ...Kh6 allows Nc5 with fork ideas? Nc5 attacks b7? No. Let me think of White's simplest win: Bc4-d5-b7 tricks? White can maneuver B to d5 then Nb7... Check for stalemate tricks? No. Any immediate tactic: ...c5 and if Bxc5 then ...Kh6? Nothing. ...g5 then ...g4, ...Kh6, ...Kg5 maybe targeting f2/h2 pawns. With R h1, White plays h4. Eh. I'll play ...g5.

Completely down to a king and two pawns against a small army — time to dig into survival mode. Pushing the g-pawn creates luft and opens the king's escape toward the center.

The opponent threatens g4 trapping... actually just need to make progress. Bf7 is a good move controlling g8. Let's think: Black king h7, pawns c6, g5. White: Kc1, Rh1, Bc4, Nb7, pawns a2,b2,c2,f2,g2,h2. Mate plan: Bf7 controls g8; Nd6? Knight on b7. Simple plan: Bf7 then Rh1... actually Rh1 is blocked by h2? Rook on h1, pawn h2 — rook can't go down h-file. Re1, Rf1 etc. Good plan: Bf7 followed by g3/g4 or Rh1 lift. Actually rook needs to move — Re1 then Re7? Let's find fastest mate. Bf7 threatens Rh1... no. Idea: Bf7 pins/controls g8, then h4 gxh4? Then Rh1 opens... hmm, h4 g4 blocks. Simplest winning: Bf7, then Re1, Re7 threatening Re8 mate? King h7, Re8+ Kg7... not mate but wins. Mate threat: after Bf7, knight d6 threatens Nf5+? Let's just check Bf7 g4 then h3 h5 hxg4 hxg4 Bxg8... wait g5-g4, h2-h3, h3xg4? g4 pawn... pawn h3 captures g4 (if black played g4). Then bishop h6? Bishop on f7 to... f7 controls g8. Bf7 aims at... c4-f7 diagonal targets g8. Then Rh1 blocked. Better: play Re1, then Re7 hitting... nothing. The strongest simple move: Bf7 g4 hxg5? No, h2-h3 g4 h3xg4 hxg4 then Bxg8... Bishop f7 takes g8?? nothing there. Plan mate: g3 (luft?), Bf7, then h4? Let's think of a direct mating attack: Nc5 (attacking c6), Nd7 also. Nd8 attacks c6 too. Fastest mate likely: 29. Bf7 g4 30. h3 h5? Black only has pawn moves: c6-c5, g5-g4, h... black has no h-pawn? Black pieces: Kh7, c6, g5. Only two pawns. So Black's moves: c5, g4, king moves. King can't move anywhere? Kh7: g8 (Bf7 controls g8), h8, g6, h6. h8 and g6/h6 available unless attacked. Rook h1 controls h-file? No, h2 pawn blocks. So 29. Bf7 g4 30. h3 gxh3 31. g3 (or Rxh3?) Rxh3! then rook active: Rh3 then Rg3? Black king h7... after 30.h3 gxh3 31.gxh3? no, pawn g2 takes? g2xh3 yes. Or Rxh3 better: rook on h3, then Rh... black king h7, rook h3, black plays g3? pawn g4 can push g3. Hmm 30.h3 g3! then h-pawn h4? Then Bf7... black king stalemated-ish? King can go h8, g6, h6. Alternative simple: 29. Nd6 cxd6? No wait, does Nd6 attack c6? No — Nd6 attacks... b7-d6: attacks c8, b5, e8, f5, f7, e4, b5, c4. Doesn't attack c6. Nc5 attacks... b7-c5: a6, a4, b3, d3, e4, e6, d7, a... attacks e6, d7. Doesn't attack c6. Nd8 attacks c6! Nd8 attacks c6 (d8 to c6: yes). So 29. Nd8 c5 30. Nxc6? No wait after c5, Nxc5? knight d8 to c6 — c6 vacated. 29. Nd8 c5 30. Nf7! Threatening Nd8... hmm. Just simplest: Bf7 restricting, then Re1-e7, push pawns, mate eventually. Since we're up massively, just pick a strong clean move. Bf7 is good — controls g8, preparing Rh1? Rook still blocked. Actually after Bf7 g4, hxg5? h2xg3?? no. h3 g3 creates passer issues for black but white wins anyway. Another idea: 29. Bf7 and if g4 then 30. h3 gxh3 31. g3! black king has squares h6,g6,h8. Then Re1? Rook lift: Re1-h1? blocked by h3 pawn? h3 is White's pawn... no black took: g4xh3, white g2xh3? gxh3 recaptures? g2 pawn captures h3 pawn. Then h-file open: Rh1-h3? Rook h1, h2 gone, h3 white pawn. Rook can go h... rook on h1, pawn h3: Rh1 can move to h... h2 square empty. Fine. Maybe simpler: keep bishop pair pressure. I'll play 29. Bf7, aiming g8, then Kd2->d... Actually a clean mating net: Bf7, Re1, Re8+? Re8+ Kg... after Bf7, king can't go g8. Re8 then Rxf... hmm king h7, Re8+ Kh6. Honestly with +15 any reasonable move wins. Bf7 is solid and prepares mate. Quip about "one move to survive forever."

Black king h7, white bishop f7. Legal moves: Kh8, Kh6, Kg7, c5, g4. Need to find drawing fortress idea. White has king, rook, bishop, knight, 5 pawns vs king, pawn. Black has no drawing chances... Actually the joke is Black has only king and c6 pawn. Move 28...g5 was already played. Now move 29 for Black. Position: Kh7, pawns c6 and g5. White: Kc1, Rh1, Bf7, Nb7, pawns a2 b2 c2 f2 g2 h2. Black is completely lost. Best practical: maybe Kh6 heading somewhere? Nothing wins. Let's pick best move. Kh6 threatens g4 and c5. Kg7 attacks bishop f7? Kg7 attacks f7, yes bishop would move. Kh8? Let me think about survival joke — Kh8 perhaps. Actually g4 frees... nothing matters. Maybe Kg7 attacking the bishop — the bishop must retreat. Kh6 allows Bg8+? Bf7 bishop on f7; Kh6 then Bg8? No, Bg8 isn't check. Kh6 then Rh8+? White rook h1: Kh6, Rh8#? Kh6, king on h6, Rh8+ Kg... king h6 can go g6? No, Kg7 available. Rh8+ Kg7. Not mate. Best move practically: maybe Kg7 hitting bishop. Or Kh6 planning Kg5 hitting pawns... f2, g2 pawns: Kg5 attacks f4? Pawns f2 g2 — Kg5 threatens nothing immediate; after ...Kg4 maybe hxg... wait White pawns: after Kg4, Black king attacks g3? Actually Kg4 attacks f3? Not pawns. Kh6 then Kg5, then Kg4 threatening ...Kxg... hmm Kg4 could be met by h3? No hxg? h2 pawn: Kg4... White can play h3+? h2-h3+ check? Kh4 then. Meh. Kg7 hitting the bishop seems most active. Play Kg7.

Down two pieces of material to an army, but the knight on b7 and bishop on f7 look nervous — the bishop's on my target list.

GLM 5.3 High· move 30

Position: Black king g7, bishop f7 attacked by king? Bishop on f7 is adjacent to king g7 — the bishop is attacked by the king! Wait, Bf7 and Kg7: g7 to f7 is adjacent, so king attacks bishop. Bishop is protected by... Nb7? Nb7 doesn't defend f7. Rh1? No. So bishop is attacked. I said "take away g8" last move — bishop on f7 also would attack g8 but it's attacked by king. Wait, is the bishop defended? Nb7 attacks d8, d6, c5, a5. Not f7. So Black threatens Kxf7. Need to move bishop or defend it. Bishop moves: Be8, Bg8, Bh5, Be6, Bd5, Bc4, Bb3. Best: mate threat? King g7, knight b7. If Be8 then threatening... King g7 escape squares: f6, g8, h7, h6, f8, f7, g6, h8. Bishop on e8 covers f7. Knight b7 covers d8, d6. Hmm, Bg8+ would be check? Bg8 attacks f7... g8 to g7? No, bishop doesn't attack along rank. Bg8 attacks f7, h7 diagonals... bishop attacks diagonally: g8-f7-e6 and g8-h7. King on g7 is adjacent to g8 but bishop doesn't give check. Can I mate? Black king g7. Consider Be8 then Kf6... Let me think of a mating plan. Material huge; knight + bishop + rook vs bare king. Mate soon. Check moves available: none of the legal moves give check directly? Bd5 check? d5 to g8 diagonal: e6, f7, g8 — no. Bh5? h5 attacks e8 diag, not g7. Be8: no. Knight moves: Nd8 no check. So no checks. Actually, could I trap: play Be6 threatening Bh6#? Bh6 with bishop from... Be6 aims at h3... Be6 covers g8 and h7? e6 diagonals: d7,c8 and f7,g8 and f5,g4,h3 and d5,c4,b3,a2. So Be6 covers g8 and f7. King g7 squares: f7 (bishop covers after Be6? Yes f7 on e6 diagonal), g8 covered, h7 covered by Rh1? Rh1 covers h-file: h7 yes! Rh1 on h1 covers whole h-file including h6, h7, h8. So king squares: f6, g6, h6, f8, h7(covered by rook), g8, f7, h8(covered by rook). King currently can go: f6, g6, h6, f7?? Kf7 attacks bishop... wait after bishop moves away. Plan: Be6 restricts to f6, g6, h6, f8. Then march king up? Or Rg1+ later. Actually simpler: black only moves king; avoid stalemate. Black king on g7 with pieces to move. Consider Be8: covers f7; then king can go g8? Be8 doesn't cover g8. Hmm. Best concrete mate: Rg1+ first? Rg1 is legal — rook from h1 to g1, no check (king g7, g-file: g2 pawn blocks). No. Think: mate pattern with rook on h-file, bishop controlling f7/g8, knight covering f6 area. Let me consider Be6. Then Black king moves: f7 illegal (bishop), g8 illegal, h7 illegal (rook), f6, g6, h6, f8 possible. So Be6 then Kf6/Kg6/Kh6/Kf8. Then Bh6#? If Kh6... Let me find a forced mate sequence. Alternative: Bb3 aiming... Bb3 covers f7, g8 (b3-c4-d5-e6-f7-g8). Then king squares: f6, g6, h6, f8, g8 covered, f7 covered, h7 rook. Then follow with knight to... Nd8 covering f7 too? Or Rg1 then mate. Actually with Bb3, black king confined to f6, g6, h6, f8. Then Kd2? Slow. Use knight: Nc5 heading to e4... mate on g6? Pattern: knight on e5? Hmm. Let me think of mate: Kg6, Rg1+ with pawn? g2 pawn there... Mate pattern: white Kc1 far. Mate likely: rook to g-file cutting, bishop + knight. E.g., black king h6, then Rg1... rook delivers along g? Common mate: king on g6/g7, Nd5... hmm. Let's try: 30. Be6 Kf8 (or others). 31. Nd6? covers e8, f7... Maybe quickest: 30. Be8, planning Nd6 covering f7? Be8 covers d7... Be8 covers f7! e8-f7 diagonal. Yes Be8 attacks f7. And knight to d6 attacks f7, e8... Let me just evaluate: after Be8, king can go g8, f6, g6, h6. Then Nd6 threatening... knight d6 attacks f7, e8, c8, b7, b5, c4, e4, f5. Covers f5, f7. Then Rh1 already covers h-file. King on g6: squares f5 (Nd6 covers), f6, f7 (covered), g7, h5?? king can't capture... Alternative mate plan: get king to g8 corner: with bishop on h7... Bh5 then Bg6+ forcing... Let me try a line: 30. Be6 Kf6 (say). 31. Nd8 (threat?) ... hmm. Actually a clean known technique: rook h1, bishop controls f7/g8 line, knight controls... Mate: Kg6, Bh5+! Kf6, Rf1#? Bishop h5 covers g6, rook f1 covers f-file, mate if king can't escape to e5,e6,e7 etc. King f6 needs e5, e6, e7, f5, f7, g5, g6, g7 covered. Simpler: push king to edge and mate with rook check on adjacent file. King g7 now. Try: 30. Be6 Kf8 (or Kg6/Kh6/Kf6). If Kh6 31. Rg1! Kg7... wait rook g1, g-file open (g2 pawn!). g2 pawn blocks rook. So rook needs g-file: pawn g2. So Rg1 useless. Rf1? f-file: f2 pawn blocks too! All pawns on rank 2 block rook. Hmm, rook on h1 only has h-file. So mate must come via h-file or king walk. Rook mates on h-file: king g7 with bishop covering f7 and f8? Mate pattern: Rh8+?? king escapes. Mate: king f8 with Rh8#? Rh8 check to f8? No, rook h8 attacks h-file and rank 8: f8 yes! Rh8+ on rank 8 gives check to king on f8. King f8 escapes: e7, f7, g7? Need covered. So mate pattern: king f8-ish, rook to h8 mate, with knight/bishop covering e7, f7, g7, e8? Let's construct: bishop e6 covers f7, g8. Knight d6 covers f7, e8, f5, b7... need e7, g7. Hmm. Alternatively mate with king help: march king up. With such material advantage, no rush. Let's find forced mate quickly-ish. Position: black king g7, black to move after our move. Let's try 30. Be8: - Covers f7. Black: Kg8, Kh6, Kg6, Kf6. - 31. Nd6 covers f5, f7, e8. If Kg8: then Bh5! covers g6? h5-g6 yes and e8... then king g8 squares: f7 (B e8), f8, h8 (rook), h7 (rook). 33... hmm. Actually mate on g8: king g8, rook h1 covers h7, h8. Bishop h5 covers g6. Knight f7?? Knight could go Nf7+? From d6, Nf7+ forks... Kxf7 no. Knight mate: Nf7+ from... knight on d6 to f7 is check to g... f7 knight attacks h8, h6, g5, e5, d8, d6... not g8. Knight e7 attacks g8! Knight on e7 attacks g8, c8, g6, c6, d5, f5. So plan: king g8, knight to e7 covers g8?? No wait we want mate. Mate pattern: king g8; Rh1... rook needs to give check on h-file only if king on h. King on g8: mate with bishop controlling f7/f8, knight e7... hmm knight e7 attacks g8 — that's check not mate setup. King h8: rook h1 gives check? h-file, king h8, rook h1 check — but king escapes g8, g7 unless covered. Mate pattern: Kh8, Nf7#? Knight on f7 attacks h8, h6, d8, d6, e5, g5 — check from f7 to h8 yes. King h8 escape g8, g7. Bishop e6 covers g8, f7. So Nf7+ Kh... if Kg7 blocked? Bishop covers f7 so king can't capture knight. King h8 with Be6 (covers g8, f7) and Nf7#: king h8, knight f7 checks, escape squares g8 (bishop), g7 (knight attacks... f7 knight attacks g5, h6, h8, d8, d6, e5 — not g7!). g7 not covered by anything? Rook h1 covers h-file not g7. So Kg7 escapes. Need g7 covered: rook... hmm rook on g-file blocked. Alternative: mate with Bf7#? no. Let me reconsider: maybe simplest is march the king up: Kd2, Ke2... slow but with such advantage fine. But opponent could move king around; zugzwang stalemate risks. Actually maybe faster: use rook lift via h-file: Rh8+? Rook h1 to h8: path h2 own pawn blocks. Pawns h2, g2, f2 on rank 2. Could advance pawns: h4, g4 etc. Not fast. Knight b7 is far. Let's compute mate systematically. Black king zone confined by: rook h1 (h-file), and bishop controlling diagonals. Try 30. Bh5. Bishop h5 covers g6, f7, e8... wait h5 diagonals: g6-f7-e8 and g4-f3 and e4? h5 up-left: g6, f7, e8. So covers g6, f7, e8. King g7 squares: f6, g6 covered, h6, f8, f7 covered, g8, h8 rook, h7 rook. Black: Kf6, Kh6, Kf8, Kg8. If 30...Kg8 31. Nc5 (heading e6 or d7?) Hmm bishop h5 covers g6? then king g8: f7 covered, f8, h8/h7 rook. 31...Kf8. Try 30. Be8 line deeper: 30. Be8 Kg8 31. Nd6 (covers f7, e8, f5) 31...Kf8 32. Bh5! covers g6, e8? king f8: squares e7, f7 (covered), g7, g8 (bishop e8? bishop moved to h5 — h5 covers e8-g6... doesn't cover g8). Hmm king f8 can go g7, g8, e7, e8? e8 attacked by bishop h5? h5-g6-f7-e8 yes! e8 covered. So king f8: e7, g7, g8 free. This is getting messy. Use a different approach: known winning technique for R+B+N vs K: bring rook to a file/rank, use king. But with huge material and pawns, we can advance king: Kd2-c3... actually king can walk to f3 etc. Pawns on 2nd rank protect each other. But actually there might be a quick mate: 30. Be6 Kf8 31. Nd6 (threat Rg1? no) ... 31...Ke8?? no wait Kf8 can take? f8 adjacent to e6? No. Let me try: 30. Be6 Kf8 31. Nd6 Ke7?? No king can't move into... f8 to e7: attacked by bishop e6? No. By knight d6? d6 attacks e8, f7, f5, c8, b7, b5, c4, e4. e7 not attacked. So Ke7 possible? Then king approaches pieces. 32. Bf5+? e6->f5 check? f5 attacks e6... king e7: f5 diagonal to e6, g6, h7... doesn't check e7. 32. Bc8+? e6-c8: d7, c8. Check to e7? No, bishop c8 attacks b7... rook line: not check. Hmm, maybe just bring king: 30. Be6 Kf6 31. Kd2 Kg7 32. Ke3? ... Then mate with king support: e.g., Kf3-e4 etc. But black king can approach White's pieces and attack bishop. Honestly, engine-wise, best move probably Be6 or Be8, keeping restriction. Let's verify Be6 doesn't allow stalemate anywhere: after Be6 black has Kf6, Kg6, Kh6, Kf8 — fine. Then plan: with king on, say, h6: 31. Nc5? covers e6... Let's find mate vs Kh6: Rook h1 covers h-file (h7, h8). King h6: g5, g6, g7, h5, h7(rook), h8(rook). Bishop e6 covers g8, f7, f5, g4. So g5, g6, g7 free. Move bishop... Bh3+? e6-h3: f5 g4 h3. Bh3 covers g4... check to h6? No. Be8 covers d7..., Be8 to check h5? No. Vs Kh6, mate idea: Bf5+! e6-f5 check? f5 attacks g6, e6... check from f5 to h6? f5-g6-h7 diagonal — no, that's toward g6/h7, not h6. Not check. Bd7? covers g... Knight maneuver to g4 or f5: Nf5+ from... OK here's a known mate: king h6, Nf5+ (double? no). Nf7+ from d6: attacks h8, h6 — yes knight f7 checks h6! Then king h6 escapes g5, g6, g7, h5. Need those covered. Bishop e6 covers g4?? not these. Rook covers h-file only. Standard mate: K on g6: Rf1... blocked. Given complexity, maybe engine prefers king march: With K+R+B+N vs K, mate by force regardless; king walk is safe. But opponent king might harass: Kg7 can attack f7 bishop etc. After Be6, if Kf6 attacks bishop e6? King f6 adjacent e6 — yes attacks! Bishop defended by? Nothing. Hmm so Be6 Kf6 attacks bishop, we move bishop again. That's fine but let's see: 30. Be6 Kf6 31. Bc8 (keeping d7... covers b7? bishop c8 attacks b7 knight own... ) bishop retreat: Bh3, Bf5+, Bd5, Bc4, Bb3, Ba8? from e6: d5, c4, b3, a2 occupied... a2 pawn. Diagonals from e6: d7-c8, f7-g8, f5-g4-h3, d5-c4-b3-a2. So Bd7, Bc8, Bf5+, Bg4, Bh3, Bd5, Bc4, Bb3. After Kf6, Bf5+? Check to king f6: bishop f5 adjacent — yes check. Kxf5? Is f5 defended? Knight b7 no. So Bf5+ Kxf5 loses bishop! So bishop must retreat keeping distance: Bh3, Bd5(covered? no), Bc4, Bb3. 30. Be6 Kf6 31. Bc4 (covers f7-g8 line, safe). 31...Ke7? King f6 to e7: attacked? No. Hmm king gets active. Maybe 30. Be8 is better: covers f7, and is farther from king. 30...Kg8 31. Nd6 then? King g8: h8 rook, h7 rook, f7 bishop, f8 free, g7 back. 31...Kf8 32. Bh5 covers g6, e8, and... king f8: e7, g7, g8 free. Hmm. Alternatively 30. Be8 Kf6 31. Nd6+? No, d6 knight doesn't check f6... knight d6 attacks f5, f7, e8, e4, c4, b5, b7, c8. Not f6. New idea: use knight to cover g5/g6 area. From b7: Nc5 then... Nc5 attacks e6, d7, b7, a6, a4, b3, d3, e4. Then Ne4 covers g5? e4 attacks g5, f6, d6, c5, c3, d2, f2, g3. Ne4 covers g5 and f6! Plan: 30. Be8 (cover f7) Kf6 (say) 31. Nc5 then 32. Ne4+ hitting king... e4 knight attacks f6: check! Then king moves, e4 covers g5. Vs king g6: knight e4 covers g5, f6. Bishop covers f7? e8 covers f7? e8-f7 yes. Rook h-file covers h5,h7,h8. King g6: f5, f6(N), g5(N), g7, h5(R), h6. f5 and g7, h6 free. Hmm. Vs king g7 with Ne4: squares f6(N), g6, h6, f8, h7(R), h8(R), g8?, f7(B). So g6, h6, f8. Then Bg6+! From e8: e8-f7-g6, check! King g7... wait if bishop goes to g6+ king g7 can capture? g6 adjacent, defended by knight e4? e4 doesn't defend g6. Rook? No. Hmm, Bg6+ Kxg6. Bad unless supported. Maybe bring rook: Re1? f2 pawn blocks... rook can't easily get to center files. Rook is stuck on h1 behind pawns; only h-file. Unless pawns move. Given the stalemate dangers, perhaps simply improve king: 30. Kd2!? But bishop f7 hangs: Kxf7. No. So we must address the bishop being attacked by Kg7! Legal moves include bishop moves and also... wait, is bishop actually attacked? King g7 adjacent f7, yes. So we must move bishop or defend it. Can we defend f7? Rh1 to... no. Knight b7 can't. So bishop must move (or... no other option). Among bishop moves: Be8, Bg8, Bh5, Be6, Bd5, Bc4, Bb3. Bg8: then Kxg8?? King g7 can take g8? g7-g8 adjacent, bishop g8 defended? Knight b7 no, rook h1: h-file — g8 not on h-file. So Bg8 Kxg8 loses bishop! Wait bishop g8 attacked by king g7? Yes adjacent. Wait but earlier I quipped about g8... Anyway Bg8 hangs. Also Be8: attacked? King g7 not adjacent e8. Safe, and e8 covers f7. Be8 seems natural: covers f7, safe. Also Bh5 covers f7 and g6 and e8. Be6 covers f7, g8. Which squares does Black king have: After Be8: g8, f6, g6, h6, f8. (f7 covered, h7/h8 rook). Wait f8: attacked by knight b7? No. So Kf8 possible — then king attacks e8 bishop! Hmm: 30. Be8 Kf8 attacks bishop; bishop defended by? Nothing (knight b7 doesn't cover e8... d6 covers e8). Then we must move bishop again. Meanwhile Be6 covers f7 and g8, king f6 can attack e6. After Bh5: king g7: f6, f8, g6 covered, g8, h6, f7 covered? h5 covers f7 yes. So Kf6, Kf8, Kg8, Kh6. Kf6 doesn't attack h5? f6-h5 not adjacent. Good. Kg8 attacks h5? No. King never attacks Bh5 except from g6/g4/f4/f6? h5 adjacent: g6, g4, f4... f6 no. Only g6 attacks h5, but Bh5 covers g6 so king can't go there (moving into check? King can't move to a square attacked by bishop — g6 attacked, so illegal). So Bh5 is safe from king permanently while it stays! Nice. So 30. Bh5: covers f7, g6, e8, g4, f3. Black: Kf6, Kf8, Kg8, Kh6. Now plan: knight to e4 or d6, and rook... Mate construction with Bh5: covers g6, f7, e8, g4. Black king on g8: squares f8, g8, h8(R), h7(R), f7(B). King g8 must go f8 (or f7 illegal). Black king on f8: e7, e8(B), f7(B), g8, g7, h8(R). e7, g7 free. King f6: e5, e6, e7, f5, f7(B), g5, g6(B), g7, h5(B), h6, h7(R). Many free. Knight maneuvers: Nc5-e4 or Nd6. Knight d6 covers f7, e8, f5. With Bd... hmm. Mate idea with Bh5 + Ne4? Ne4 covers f6, g5, d6, c5, c3, d2, f2, g3. King g7 then: f6(N), g6(B), h6, f7(B), f8, g8, h7(R), h8(R). Free: h6, f8, g8. Then Bf7+?? bishop h5 to f7: check to g8? f7 attacks g8 yes. If king g7: Bf7+?? king takes. Hmm. With Ne4, if black Kh6: Rg1 no. If Kg8: 32...? Let me consider knight route to f5 or h... Mate pattern for king h6: Bf... Classic R+B+N mate: e.g., king h6, Bg4? covers h5... Nf5+ then... Try concrete: 30. Bh5 Kf8 (trying e7) 31. Kd2? Slow. Or 31. Nc5 (threat Ne6? c5-e6 attacks... e6 from c5: d7, e6 — attacks e6, d7; king f8... ) Hmm. Alternative approach: 30. Bh5 Kg8 31. Nc5 Kf8 32. Ne6! attacks d8, f8? knight e6 attacks f8! Check? King f8, knight e6 attacks f8 — but bishop h5 pins? No. So Ne6+ Kf... wait king f8 in check from knight e6: escapes e7? attacked by knight? e6 knight attacks d8, f8, g7, g5, f4, d4, c5, c7. e7 not attacked; bishop h5 attacks g6, f7, e8, g4. So Ke7. Then 33. Nc7+? attacks e8, e6... king e7: Nc7+ forks? knight c7 attacks e8, e6, a8, a6, b5, d5. Check to e7? No. Nc5+? from e6-c5... knight e6 to c5 attacks e4, d7... not e7. Bg6+? h5-g6 check to e7? No, g6 attacks f7, h7, f5, h5. No. 33. Nc7+ Kd6?? king can chase knight. Hmm, this king is slippery. Standard technique: confine to corner and mate: Kh8 mate: Nf7# requires g8, g7 covered. With Bh5: covers g6... rook h1 covers h7. So Kh8: Nf7+ (from d6 or e5): escape g8? g8 attacked by? Bishop h5? No (h5 attacks e8,f7,g6 diag and g4). Rook? No. So g8 free. Need bishop on diagonal covering g8: bishop on f7... Mate on h8: pieces: Rook h1 checks? Rook can't reach h8 (pawn h2). Move h-pawn? h4, h5, h6! March h-pawn: h4-h5-h6 with king g7? Then rook... but pawn h6 could be captured? Black king g7 attacks h6. Hmm. Alternatively mate on g8: Bf7+ Kxg... Honestly, maybe I should consider 30. Nd6!? — bishop f7 is attacked, so no. OK, practical decision: choose a strong, safe restricting move. Between Bh5 and Be8 and Be6 and Bd5. Bd5 covers g8, f7? d5 diagonals: e6-f7-g8 and c6 pawn blocked, e4, c4, b3, a2. So Bd5 covers f7, g8 (if e6 empty — yes). Also safe from king. Black king: f6, f8, g6, h6 (g8 covered, f7 covered, h-file rook). Similar to Bh5 but also covers g8. Then knight to e4/f5 next. Actually Bd5 vs Bh5: Bd5 covers g8 and f7; Bh5 covers g6 and f7 and e8. King can go g6 vs Bd5? g6 attacked by? Nothing? Bd5 attacks f7... no wait d5-e6-f7-g8: doesn't touch g6. So Kg6 possible, then Kg5-h4 escape route toward center! That's bad — king could run via g5/f5 toward center and attack our pawns. With Bh5, g6 is covered, king confined more: Kf6, Kf8, Kg8, Kh6 — still Kf6 then e5, e6, e7... king can escape via f6 to e5/e6. Hmm, but then knight covers: Nd6 covers f5, e8, f7. King f6: e5, e6, e7, g5, g7... To prevent central escape, need knight covering e5/e6/e7 region or king support. Knight from b7: Nc5 covers e6, d7; then Ne4 covers f6, g5, d6, e... covers f6 and g5. King f6 can't stand? If knight e4 and king f6: Ne4 gives check? e4 attacks f6 yes. So king at f6 gets checked. Line: 30. Bh5 Kf6 31. Nc5! (threat Ne4+ driving king to edge) 31...Ke7? King f6 to e7: 32. Ne4 covers f6... then 33. Nd6? threats... Or 31...Ke5? attacked by knight c5? c5 covers d7, e6, b7, a6, a4, b3, d3, e4. e5 not attacked. But then Bh5-g6? hmm, 32. Nd7+? no. Honestly, we have all the time in the world; even simplest: keep bishop safe, bring king up: Kd2-e2-f3... Actually with king walk, mate is easy: e.g., king to g3/f3 area, then mate with K+B+N+R. But careful about stalemate — with correct play no stalemate since we have pawns and multiple pieces; black king always has squares. But the game presumably wants best move now. Let me try to find forced mate within reasonable depth. Material: R, B, N, K, 6 pawns vs lone K. Any reasonable line wins. Best practical: 30. Bh5 Kf6 (best?) 31. Nc5 (heading e4/d7) ... Alternatively, check the possibility of immediate trap: black king g7 currently; after 30. Bh5, black moves: - Kf6: then 31. Be2!? covering b5... hmm. Or 31. Nc5 Kf5?? 32. Nd7? ... 31. Nc5 threatening Ne4+ next: if 31...Kf5 32. Nd7? no. 32. Ne4 no wait knight on c5 can go e4? c5-e4 yes! 32. Ne4+ Kf4?? attacked... king f5 in check from e4: king must not capture (e4 defended by? nothing... Kxe4?? then Bh5 covers e8... after Kxe4 black king free, bad). Hmm Ne4+ from c5: is e4 defended by bishop h5? No. But king f5 adjacent e4: Kxe4 wins knight unless defended! So don't do that. OK let me stop trying to calculate mate fully and just pick a clean strengthening move. I think 30. Bh5 is good: keeps bishop safe, covers f7/g6, confines king. But wait — maybe there's something better: 30. Bd5!? keeps g8 covered, and plan Nd6 next covering f5, f7, e8 — then king has only... after Bd5, black Kf6/Kg6/Kh6/Kf8. If Kg6 31. Nd6?? doesn't cover g5. King g6 threatens g5-h4 run. 31. Nc5 covering e6, then Ne4 covers f6, g5. King g6: f5, f6? e4 covers f6, g5. So f5, g7, h5?? h5... rook covers h5? Rook h1: h-file: h5 yes! Rook covers entire h-file (no blockers). So h5, h6, h7 covered by rook. King g6: f5, f6(N), g5(N), g7, h5(R), h6(R), h7(R), f7(B d5). Free: f5, g7. Then Bh1?? Hmm, then Bf7?? no wait bishop on d5: could play Be4+! d5-e4: check to g6! King g6 in check from e4 (e4-f5-g6 diagonal). Escape: f5? e4 adjacent... f5 attacked by bishop e4? e4 covers f5 yes. g5 (knight), g7, h5(R), h6(R), h7(R), f7(B), f6(N). So Kg7 forced. Then... Interesting. Let me evaluate line: 30. Bd5 Kg6 (black's most active) 31. Nc5 (threat Ne4) 31...Kg7 32. Ne4 threatening Bf7+?? or... king g7: f6(N now? knight e4 attacks f6 yes), g6, h6, f7(B), f8, g8(B), h7(R), h8(R). Free: g6, h6, f8. Hmm 33. Bf7? no. 33. Nd6+? e4-d6: check? knight d6 attacks f7, f5, e8, c8, b7, b5, c4, e4 — not g7. No. This isn't converging quickly. In R+B+N vs K mates, knight+rook coordination: e.g., king g7, Rg1? blocked. Let me think about the h-pawn idea: advancing h4-h5 forces... King g7 stops h6 (Kxh6? h6 defended by... after h6, king g7 can take h6 if undefended — defended by rook h1? No, pawn h6 blocked... rook behind on h-file: pawn h6, rook h1 — rook defends h6 along file? Path h2-h5 must be clear: h2 empty after pawn moves. So rook defends h6. Then Kxh6?? illegal (defended by rook). So h4, h5, h6 creates luft and rook defends. Then black king must avoid h-file... then rook still behind pawn. Hmm. Alternatively, plan: mate in the h8 corner with the classic Bf7... no wait, with pawn h6 and rook, etc. Let me just search mentally for mate in 4-5 vs typical defenses. Take 30. Bh5 as move 1 of plan. Black replies: Kf6, Kf8, Kg8, Kh6. Case A: 30...Kg8 31. Nc5 Kf8 (only? g8: f8, h8(R), h7(R), f7(B). Yes only Kf8!) 32. Ne6+ Kf... wait knight e6 attacks f8: check. King f8 escapes: e7, g7? g7 attacked by Ne6? e6 knight attacks g7 yes! f7 (B), e8 (B). So only Ke7. 33. Nc7+? no. 33. Nc5? Hmm. After 32...Ke7 33. Bf3!? covers b7... or 33. Nd8+? e6-d8: knight d8 attacks f7, b7... check to e7? No. 33. Nc7+? attacks e8, e6: no check to e7... c7 attacks e6, e8, a8, a6, b5, d5. Not e7. 33. Nc5+? from e6: knight to c5 attacks d7, e6, e4, b7, a6, a4, b3, d3. No check. Hmm. After 32...Ke7, white pieces: Bh5, Ne6. King e7 fairly central. 33. Kd2 heading to support. E.g., Kd2-d3-e4/e5 then net closes. Alternatively at move 31: 31. Nd6!? from b7 directly: covers f5, f7, e8. Then king g8: f8? f8 attacked by Nd6? No (d6 covers e8, c8, f7, f5, b7, b5, c4, e4). King g8: f8, h8(R), h7(R), f7(B h5? h5 covers f7 yes... wait Nd6 also covers f7). So Kf8 forced again, then... bishop h5 gives g6 coverage; king f8: e7, e8(Nd6), f7(N), g7, g8. So Ke7 or Kg7. Then 32. Nc4? hmm. Case B: 30...Kh6 31. Nc5 (threat: Ne4 covering g5) — king h6: g5, g6(B), h5(R), h7(R), h8(R), g7. Free: g5, g7. Threat Ne4 covers g5... then 31...Kg7 32. Ne4 g7→ f6(N), g6(B), h6, f7(B), f8, g8, h7(R), h8(R). Free: h6, f8, g8. 33. Nf6?? e4-f6: knight f6 attacks g8, h7, h5, e8, d7, d5, e4, g4 — attacks g8! and h7. King g7... Nf6 is not check. But covers g8, h7... hmm king g7 attacked by knight f6? No. Then black king: f7(B), g6(B), h6, h8(R), f8, h7(N), g8(N). Free: h6, f8. Getting tight! 33...Kf8 (or Kh6). If Kh6: 34. Bf7?? no. 34. Ng8!? f6-g8: attacks h6! Check! Knight g8 attacks h6, f6, e7. King h6: g5, g6(B), h5(R), h7(R), h8(R), g7. Free: g5, g7. Hmm not mate. 35. Nd... If instead 33...Kf8 34. Nd7+!? f6-d7: check to f8? d7 attacks f8 yes! King f8: e7, e8(B h5), f7(B), g7, g8, h... e7 free? d7 knight attacks f8, b8, b6, c5, e5, f6. e7 not attacked, g7 not attacked. 34...Ke7 or Kg7. I keep going in circles; mate probably around move 35-40 with king walk needed. Fine — but for this single move, choose between Bh5/Be8/Be6/Bd5. One more consideration: 30. Be6!? covers f7 and g8; if 30...Kf6 31. Bc4 (retreat) 31...Ke7?? king wanders... but actually black king coming out is fine for us? It can't do anything; we can always push it back. But engine would prefer keeping it boxed. Bh5 keeps king most restricted and bishop untouchable. Also covers e8 and g4, f3. I'll go with 30. Bh5. Wait — double-check legality: Bf7 to h5: path f7-g6-h5, g6 empty yes. Bishop lands h5. Legal (in list). Good. Also quip: opponent said bishop's square first on eviction notice. Respond playfully.

Your bishop's being eyeballed by that king — time to relocate it somewhere untouchable while keeping the cage tight.

Played Bh5

Bh5f7 → h5

Eviction notice denied — my bishop just moved somewhere rent-free, and your king's still stuck in the studio apartment.

I'm down to king, c6 pawn, g5 pawn. White has B, N, R, 5 pawns. Legal: Kf8, Kg8, Kh8, Kh7, Kh6, Kf6, c5, g4. Position: Black Kg7, pawns c6, g5. White: Kc1, Rh1, Bh5, Nb7, pawns a2 b2 c2 f2 g2 h2. Consider c5 - passes pawn. Kf6, Kh6 attacks g5? White bishop h5 can take? Bh5 attacks g4, f7, e8, d1, g6, f3... g5 pawn guarded by king. Move g4: attacks Bh5. Bishop can take g4? Bhxg4 - no, g4 pawn would be defended by king g7... wait king on g7, g4 pawn - adjacent? g7 to g4 no. If 30...g4, bishop takes g4? Bh5xg4 - bishop moves diagonally h5-g4 yes. Then king can't recapture. Bad. c5: pawn marches. White will probably just... Nb7 is far away. Kf6/ Kh6 approach. Actually maybe best is c5 to create passer, then bring king. But realistically, lost position. Just make a reasonable move, maybe c5 for drama, or Kh6 attacking bishop? Kh6 attacks... king g6? Kh6 doesn't attack h5? King on h6 attacks g5, h5, g6, h7, g7. Yes! Kh6 attacks the bishop on h5! Bishop must move; it could take g5? Bishop on h5 can't take g5 (not diagonal). Bg6 pins? Bishop moves: g6, f7, e8, g4, f3, e2, d1. If bishop moves to g4 or elsewhere, Kxg5 next. So Kh6 attacks bishop and g5 pawn is defended. After Kh6, bishop retreats e.g. Bg4 or Bf3, then Kxg5. King then can help. But c5 also possible. Kh6 seems best practically. Actually wait: after Kh6, could White play Bh7? Bishop h5 to... h5-g6-f7: Bg4 attacks nothing; g5 pawn defended by king. White may play Be8 etc. Then Kxg5. Choose Kh6. Quip trash talk.

The bishop squatted rent-free, but my king's about to walk up and change the locks.

Played Kh6

Kh6g7 → h6

Rent-free? Enjoy it — my king's coming to collect, with g5 as the security deposit.

GLM 5.3 High· move 31

Black king on h6, has pawn c6 and g5. White is up massively. Need to deliver checkmate or win g5 pawn. Bishop on h5 attacks... h5 bishop. If I play Bg4? No check. How to trap the king: Kh6 with g5 pawn. If bishop takes g5? Bishop on h5 can't. Nf6+? Knight on b7 can't reach. Mate plan: Bg6! Then king can't move... Bg6 attacks nothing but blocks... After Bg6, Black king can't go to g7 (attacked by bishop), can't go h7? g6 bishop attacks h7, f7... King on h6: legal moves are Kh7 (attacked by Bg6), Kg7 (attacked), g5-pawn moves blocked... So Bg6! Is it check? No. King on h6 squares: g7 (bishop attacks), h7 (bishop attacks g6... bishop on g6 attacks h7 and h5, f7, e8). Kh5? attacked by bishop? g6 bishop attacks h5? No, g6→h5 is diagonal down-right? g6 to h5: yes that's a diagonal, so h5 attacked. So after Bg6 king has no moves! Stalemate? Black still has pawn moves: c5, g4? g5 pawn can go g4 — is g4 blocked? No. And c5, c6-c5. So not stalemate. But then g4 attacks bishop. Hmm. Better: capture g5 somehow. Knight can't reach g5 quickly. Bg6 then after ...g4, Bxg4? No, g4 pawn after ...g4 then bishop g6 can't take g4 (g6→g4 not diagonal... f5/h5 are). Actually after Bg6 g4?? then Kg7... hmm. Alternative: h4!? gxh4 — no. h4 attacks g5. If h4, pawn g5 attacked; gxh4 then Rh... no rook on h1, gxh4 pawn on h4. Then Bf7+? Kh7/g7... Let's think mate sequence. Simplest winning: Rh1! Protects nothing... Actually g4 comes with tempo next move. Consider Rg1 attacking g5. Then king must guard g5? King can't. After Rg1, g5 defended by king on h6? h6 doesn't defend g5. So Rg1 then Black must move; any move loses g5. Black could play ...Kg6 guarding? Kg6 defends g5. Or ...g4 then Bg6. Actually Rg1, if Black plays Kg6, then Bg4+? No... Rg1 g5 hangs: Rxg5+ Kh7/Kxg5? Rxg5+ Kxg5?? king takes... Rxg5+ Kxg5 loses rook. Hmm, Rxg5 is check from g5 to h6? Yes g5 attacks h6, check. King takes rook? Kg5 attacked by bishop h5? h5 attacks g6, g4... not g5. So Kxg5 possible. Bad. Better: aim for mate. Black king h6, g5 pawn. Mate ideas: Rg1 then h4 gxh4 (forced?) g5 attacked twice (rook and h4 pawn), pawn g5 can capture h4: then Bh... after Rg1 h4 gxh4, then Bf7! threatening... king h6, Bf7 attacks g8, e8, g6. Then Rxh4? no wait. Alternative plan: Kg7 covered. Let's do Bg6 planning Kg7 after. Bg6 Kg7 then Rg1! g5 falls since king on g7 defends g5? g7 defends g6, f6, f7, f8, g8, h6, h7, h8... not g5. So Rg1 attacks g5 twice? Rook only, plus... bishop g6 doesn't attack g5. King g7 doesn't defend g5. So Rxg5+?? still king recaptures? Kg7 attacks g5? No, g7 to g5 is two squares. Wait earlier: Rxg5+ Kxg5 only if king adjacent. From g7, king can't take g5. So Bg6 Kg7 Rg1 then Rxg5 wins pawn, king must go... after Rxg5, threat Rh5 mate? Rh5#? King g7, rook h5+ not mate. Actually with rook, bishop, knight vs bare king + c6, this should mate easily. Let's find fastest mate. Position: White Kc1, Rh1, Bh5, Nb7. Black Kh6, pawns c6,g5. Mate pattern: bishop controls g-file? Bh5 covers g6, g4, f7, e8. King h6. If we play Rg1 with support, and bishop covers h5... Mate: Rxg5#?? If rook takes g5, rook attacks h5? No, g5 attacks h5? Rook attacks along rank and file: h5 is on rank 5, yes rook on g5 attacks h5, g6, g4, g7... Rxg5+ — is it mate? King on h6: squares h7 (rook g-file no, rank no; bishop h5 attacks h7? no, h5 attacks g6, g4... h5 diagonal: g6, g4, f7, e8 and h-file no). h7 free? Rook g5 doesn't attack h7. So Kh7. Not mate. Standard mate: get king to h-file, Rg1 then... Plan: h4! to open. h4 gxh4 (if ...g4, then Bg6 wins). After h4 gxh4, king h6, now g5 vacated: Bf7! king... then Kg7? h6→g7 attacked by Bh5? h5 attacks g6 not g7. Kg7 then Bg6+ K moves... Simplest: use technique. Let's just play Bg6 forcing king moves, then bring rook. Actually check available checks: none right now. Compute a clean mate plan: 1. Bg6 Kg7 (or ...g4, then 2. Kg2?? no; 2. Bf7... if ...g4, king h6 can't move (h5 attacked? king h6: Kh7 attacked by Bg6, Kg7 attacked, h5 attacked). So ...g4 forced after Bg6. Then 2. Bxg4?? no. After Bg6 g4, White: 2. Kg2? no. 2. Rh1... rook already h1. 2. Kd2 waiting? Black stuck: only pawn moves g4 gone? Black has c5 and c6-c5... c-pawn still moves: c5. Hmm, then Black plays ...c5, White plays Be8+? no. Let me just plan: Bg6 g4 2. Bd3! no... Alternative: 1. h4 (attack g5) gxh4 (only good reply; 1...g4 2. Bg6 traps king: ...g4 3. Bxg4! wait bishop h5 can't take g4. 2...g4 3. Be2 then ...king stuck, ...3. Bxg4 wins pawn? After h4 g4, Be2 threatens nothing immediate. Hmm 1...g4 2. Bg6 and now black must ...c5 (only move? king can't move; g-pawn can't move—g4 can't advance? g3 blocked? g4→g3, is g3 empty? Yes! So ...g3 possible. Then g3 pawn runs. Bg6 g3 3. Be8+? no. OK simpler: 1. h4 gxh4 2. Bf7! (protecting? threatening Kg... ). Black king h6. Threat: Bg8? Hmm. After 2...Kg7 3. Bg6? bishop f7→g6: then king... Actually easiest: h4 gxh4 then Nf8+?? knight b7 to... b7 can reach d8, d6, c5, a5. Not f8. Knight route to mate: Nb7-c5-e4-g3+ hitting h5... Ng3+ then K anywhere. Let me consider: 1. Rg1 Kg6 (guarding g5) 2. Be2 (now bishop attacks g4? e2-f3-g4) no... 2. Be8+ Kh7/Kg7... Honestly any reasonable plan wins. Let's find a forced mate quickly via checks: Idea: Nc5 then Ne4-g3+ forks? Ng3+ Kg7 then Rh1... Another: 1. Rg1 Kg7 2. Bg6+!? no check... Bishop h5 gives check when king on g6/g8 file? h5 attacks g6, so if king g6 it's check. 1. Rg1 Kg6?? illegal—Bh5 gives check to g6, so after Rg1, Kg6 illegal? Wait, it's Black's move; Kg6 would move into check from Bh5. So after Rg1, Black can't play Kg6! Black king h6 moves: h7, g7 (g6 illegal). So 1. Rg1 and g5 is attacked once (rook), defended by nothing. Black options: Kg7/Kh7 abandon g5 → 2. Rxg5 then mate coming; ...g4 2. Bg6! traps king again (h7, g7 attacked; h5 attacked by bishop? g6 attacks h5 yes). Then Black must ...c5. 3. Bd... hmm then Kh6 stuck, only pawn moves. After Bg6 c5 4. Be8+?? no check. 4. Kd2 c4 5. Kd3 c3 6. Kxc3 then mate: threat Rh... King h6, pieces: Rg1, Bg6, N b7... Kg... push king? Actually mate: Rg1→h1? Bishop g6 covers h5; rook g1 covers g-file? King h6: mate pattern Rf1... Let's see: after winning g5: White Bg6, Rg1, N, K vs Kh6, c-pawn. Black king h6 with Bg6 controlling g7,h7,h5. Rook to h-file = Rh1 already there? No, rook went g1. Rook h1 was original. If rook stays h1... Oh wait! Immediate idea: rook on h1, bishop h5, king h6. If I play Bg6 covering h5/g7/h7, then king h6 has NO squares and only pawn moves. Then eventually Rh1-h... after pawn moves exhausted, Rh8#? h-file: rook h1 to h8 delivers mate along h-file? King h6 on h-file! Rh1 with bishop g6 covering g5?? no bishop covers g7,h5. Rook on h1 attacks h-file: king h6 in check from rook. Is that mate? Rook h1, king h6: escape g5 (g6 bishop attacks h5, g7... does Bg6 attack g5? no, g6 attacks f7,e8,h7,h5,f5,e4... g5 is adjacent orthogonally, not attacked). King h6 could go g5 unless blocked by pawn (g5 pawn still there!). g5 has Black pawn, so king can't move there. h7 covered by bishop, g7 covered by bishop, h5 covered by bishop. So Rh1 already gives... wait rook IS on h1 right now and king on h6 — is Black in check?? Rh1, Black king h6 — but pieces between: g5 pawn is on g5 not h-file. h2 pawn! White pawn h2 is on h-file between h1 and h6. That's why no check. OK. So plan: h-pawn moves out of the way? Move h2 pawn: h4 or h3. Then rook h1 attacks h6! But g5 pawn... rook line h1-h6: h2 (own pawn) must move, h4, h5? h5 has bishop? Bishop on h5! Bishop occupies h5. So h-file blocked by pawn h2 AND bishop h5. So reposition: 1. Bg6 (traps king) then ...g4 or ...c5 forced. 2. then move h-pawn and bishop... bishop g6 is in the way of h-file too. Hmm. Alternative mate: king h6; use rook on g-file. If g5 pawn removed: Rxg5+ Kh7, then Rh5+? Kg7/Kg8... Let's just do: 1. Rg1! Black must reply. If ...g4 2. Bg6 c5 (forced eventually) 3. Kd2 c4 4. Rxg4! now mate threat... king h6 stuck. 5. Rd4 c3+ 6. Kxc3 then mate: Kg... Rook to h-file? Bishop g6 covers. Rh4#? Rook d4-h4: king h6, rook h4, check? Rook attacks h5,h6? rook on h4 attacks h6 up the file (h5 empty? yes). King h6 escape g7? covered by Bg6. h7 covered. g5? empty now, attacked by? nothing... rook h4 attacks g4... king to g5 attacks rook? Kg5 attacks h4. Hmm. Need Rh8#? Rook h4-h8? Not check. Simpler classic mate: K+B+N vs K or K+R+B. Let's do: win g5, then walk king over? Overkill but fine. Actually here's clean mate idea: 1. Rg1 ...g4 (or king move) 2. Kg2! Kf... king goes g7. Then bishop... You know, as an engine-advisor: strongest move likely 31. Rg1 (attacking g5, forcing weakness) or 31. Bg6 (zugzwang). If Bg6, Black's only moves: g4, c5 (king can't move). Then 32. Kg2 (walking) g3+ 33. Kxg3?? king h6 then... hmm g3+ with check (g4-g3, attacks... g3 gives check to Kc1? No, pawn g3 attacks f2,h2 — not c1). Then Kg2 g3+ then Kxg3? No wait pawn on g3, Kg2 can't capture (g3 defended by king h6? h6 doesn't defend g3). So Bg6 g4, Kg2 g3+ 34... whatever, then Bxg3? bishop on g6 can't. Rook... Rh1xg... Fine. I'll play 31. Rg1. Let's evaluate Black replies: - 31...Kg7/Kh7 32. Rxg5 winning pawn; then ...Kf6 etc. White mates eventually with N+B+R. - 31...g4 32. Bg6 (king trapped, zugzwang, only ...c5) 33. Kd2 c4 34. Rxg4 (threat Kc3? or Rh... ) then mate soon: 34...c3+ 35. bxc3? b2 pawn... 35. Kxc3?? no, 35. bxc3 Kh6... wait after Rxg4, black king h6 has no moves? g5 empty now — Kg5! g5 attacked by rook g4? yes rook g4 attacks g5. So king stuck: only ...c5/c4 pawn moves then stalemate risk? Black king h6, moves: h7 (Bg6 covers), g7 (covered), h5 (covered), g5 (rook covers). So after pawn runs out, stalemate! Must be careful: before that, deliver mate: after 32. Bg6, plan Rh1→? Actually better after 32. Bg6: the g4 pawn. 33. Kg2 g3 34. Rxg3! then ...c5, and now mate: threat Rh3+? Rook g3→h3+? h3 check? rook h3, king h6 — h4, h5 empty → check. King g... escape: Kg7? covered Bg6. So Rh3 then king... wait check from h3, king can't move anywhere (g5 attacked? rook h3 doesn't attack g5... king h6→g5? attacked by rook? no. Hmm king escapes g5 then Kg4 attacks rook... Ugh. Let me instead think of the classic W: with B on dark squares... Bishop h5 is light-squared (h5 is light). Black king h6 dark square. Rook mate: get rook to h-file with king cornered... Mate pattern: Black Kh6; White Bg6 (covers h7, g7, h5); White pawn g5?? can't... White pawn g2 could go... Actually: if White pawn on g4 covering g5, then Rh-file mate: rook h1 needs h-file clear: h2 pawn → move h2-h3? then h4, h5... bishop on h5. Move bishop to g6, pawn h2→h3? then rook h1: h-file has pawn h3, bishop g6 off-file. Rook h1-h4? King h6... rook h4 checks? h5 empty, yes check, but king escapes g5? g5 pawn is Black's! King h6: g5 occupied by own pawn, g7/h7/h5 covered by Bg6. So Rh4#!! if h5 is empty and bishop g6. So mate plan: 1. Bg6 (king frozen; only pawn moves) 2. h4! gxh4 3. h... wait h4 by White pawn: g5 pawn captures h4. Then g5 empty! Then 3. Rh1 is... rook already h1, now h-file: h2 empty (pawn went h4, got captured → h4 black pawn). Rook h1: h4 black pawn blocks. Hmm. Alternative: 1. Bg6 g4 (or c5) 2. h4 gxh4 3. Rh... g5 gone! King h6, h-file: rook h1, h4 black pawn, h2 empty (wait, White played h4 from h2, pawn captured to h4 by black g-pawn). So h-file: h1 R, h4 black pawn, h6 king. Rook blocked at h4. Then 3. Kg2 → walk king? Bishop g6 covers h7,g7,h5. Black king h6 can now go g5!? g5 empty, attacked by? rook no, bishop g6 attacks h5,f5,f7... not g5. King escapes g5. Then king gets air. Alternative mate: don't play h4; instead use g-pawn: g2-g4?? blocked by black g5? g4 square: empty. g2-g4 attacks g5. If ...gxh4? no... 1. g4! g5 pawn can capture? g5xg4? no pawns capture diagonally forward: g5 captures f4 or h4 — not g4. So 1. g4 (attacks g5, and blocks... ) Black g5 pawn is attacked by g4 pawn and pinned-ish (if g5 moves, king gets exposed?). g5 defended by king h6. If Black plays ...g4? can't, g4 occupied by White pawn. So Black: king moves or ...g5 stays. If Black ...Kg7 2. g5+!? Kf6/h7... 2. Bg6 hmm. Honestly, mate isn't required instantly — just don't stalemate. Let me pick 31. Rg1 with clean follow-ups, or consider engine move: probably 31. Bg6 zugzwang is strong but risks ...g4 g3 counterplay near my king? g3+ then hxg3? h2 pawn takes g3! Yes h2 can capture g3. Fine. But actually 31. Rg1 looks cleanest: attacks g5; Black king can't defend it. Then: - 31...Kh7 32. Rxg5 and threat Rh5#? Rook g5→h5+: king h7, check from h5? rook h5 attacks h7. King escapes g8/g7? g6 attacked by bishop h5. Kg7 attacked by rook h5? h5 attacks g5, h-file... rook on h5 attacks h6, h7, h8 and g5, f5... Kg7: attacked? No. Kg7 then Rg5+... Whatever — up a rook+bishop+knight vs nothing, any safe move wins. I'll play 31. Rg1, planning Rxg5 next and gradual mate. Also avoids stalemate risks since Black king keeps squares... wait after Rxg5+ Kg7/Kh7, king free. Fine. Check legality: Rg1 — rook h1 to g1, g1 empty, path clear. Legal (in the move list, yes "Rg1"). Quip: about collecting the security deposit g5.

Let's target that g5 pawn — the "security deposit" is about to get repossessed.

Rg1h1 → g1

Rook's here to repossess that security deposit on g5 — pawn or king, something's getting collected.

Position: White Nb7, Bh5, Kc1, Rg1, pawns a2 b2 c2 f2 g2 h2. Black Kh6, pawn c6, pawn g5. Legal moves: c5, Kg7, Kh7, Kxh5, g4. Kxh5 — is h5 defended? Rg1 doesn't attack h5. Nb7 attacks h5? Knight on b7 covers d8, d6, c5, a5. No. So Kxh5 wins the bishop! Then Black has K vs K+R+5 pawns — lost anyway. g4? Then Kg4... wait black king at h6, pawn g4 then Bxg4? Bishop h5 attacks g4? Bishop on h5 moves diagonally: g4, f3, e2... yes Bxg4. Bad. Kxh5 removes a piece; then White is up rook + 5 pawns vs nothing. Still losing but Kxh5 is best. Any chance? After Kxh5, black king can attack pawns: Kxh5, then ...Kg4 attacking g2/h2? White Rg1 defends g-file. Kxg2? After Kxh5, White plays b4 or so. Black king can march g4xg3? Kxh5 Kg4, f3+ Kg3, then Kg2? Hmm. Kxh5 then ...Kg4, White plays f4 gxf4 Kxf4 then king takes h3? Let's see: pawns f2,g2,h2 plus a,b,c. White Rg1 guards g-file... Actually after Kxh5 Kg4, threat Kxg2? No wait Kxh5 then White must respond. 32. Rg2? Then Kg4 takes? Hmm, 32...Kg4 threatens Kxg2? Rg2 guards. 32...Kh4? threat Kg3. It's a draw race maybe? Black king vs rook and pawns—likely White wins, but Black king could eat h2/f2/g2 pawns. Still losing probably, but Kxh5 is the only fighting move and legal options are limited. Choose Kxh5.

They left the bishop hanging right next to my king — a delivery I can't refuse.

Kxh5h6 → h5

Repossession denied — I'm foreclosing on the bishop instead, and your deposit went with it.

GLM 5.3 High· move 32

Black king on h5 with pawn g5. Material huge. Need to checkmate or win g5 pawn. Black threatens... only pawn moves. Legal moves listed. Consider Kg2 to cut off? Or Rf1. Black king on h5; if we take g5 with... we can't take g5 yet. Nd6 then Nf5+? Let's find mate plan. Black has only king moves after... c6 pawn, g5 pawn. If Nc5 threatening Nd3? Actually let's try to force mate. King on h5, pawn g5. White to move. Mate ideas: Rg1 covers g-file but king took h5 from bishop. Now rook on g1 attacks g5 pawn? g5 occupied by pawn, king h5 defends g5? No, h5 to g5 adjacent, yes defends. Options: Kg2 walking to attack? Or h4 to make luft... Actually mate threats: after e.g. Kg2, Black must move king or pawn. Black king only squares: h4? g6? h4 attacked by rook g1? No. King h5 can go g6, h4, h6? h6 attacked? Not. If Kg2 then K moves somewhere, then Rh1 wins? Hmm. Simplest: g4+!? Kg... gxh4 available for black? g4+ check. King h5: gxh4 en passant? No, white pawn g2-g4+, black pawn g5 can capture en passant gxh4? Wait g4+ means white pawn to g4, adjacent black pawn on g5 can play gxh3? No, en passant capture only if white pawn moves two squares g2-g4 — yes! g2-g4 IS a two-square move, black pawn g5 could capture en passant gxh3?? No — en passant: black pawn on g5 captures white pawn on g4, landing on g3. g5xg4 e.p.? Black pawn moves diagonally down to g3... wait black pawns move down (toward rank 1). Pawn on g5 captures on f4 or h4 normally. If white plays g2-g4, en passant square is g3, black pawn g5xg3 e.p.? No — en passant: pawn on 5th rank (black's 4th rank from its side... black pawn must be on rank 4 for black to capture e.p. onto rank 3). Black pawn on g5 is on rank 5, not rank 4. En passant for black requires black pawn on 4th rank (e.g., g4) and white pawn moves g2-g4, then black captures gxg3. Black pawn on g5 cannot. So g4+ is safe from e.p. g4+ then king: Kh6, Kh4, Kg6? g4 pawn attacks h5... king moves: Kg6 attacked by pawn? No white g4 attacks f5,h5. King h5 in check from g4 pawn (g4 attacks h5). Moves: Kh6, Kh4, Kxg4?? Kxg4 — is g4 defended? Rook g1 defends g4. So Kg6, Kh4, or gxh4?? g5 pawn captures h4? No wait black pawn g5 captures on f4 or h4 — h4 is empty, g4 is occupied by white pawn... black pawn g5 can capture g4? Pawns capture diagonally: g5 captures f4 or h4. Not g4. So g4+ forces Kh6/Kh4/Kg6. If g4+ Kg6 then Rf1... plan Rh1#. Let's compute: g4+ Kg6, then Rf1 threatens Rf? Hmm king g6 escapes. Alternative: h4+!? h2-h4 check? h4 attacks g5, not h5. Not check. Best: g4+ Kg6 (or Kh6/Kh4). If Kh4, Kf2? then Rh1#? Kh4: Rh1#? Rook h1 checks h4, king escapes g3? attacked by pawn... wait after g4+, if Kh4, then Rh1# — king h4 escape squares: g3 (attacked by g4 pawn? g4 attacks f5,h5 — no, g3 covered by rook? no). Hmm g3: attacked by h2 pawn? No. g3 empty, legal? Rh1+ Kg3 escapes. Then Kg3... Actually let's think mate more carefully. Position after g4+: black K must move. Kh6: then Rf1? no. Consider Kg4 then Kh4 then... Maybe stronger: Kg2 first. Then black: pawn moves g5-g4+!? g5 push to g4 check? If Kg2, g5 pawn can push g4+, check? g4 attacks... black pawn g4 attacks f3,h3, not g2. Not check. Or K moves. Try: 32. Kg2 (threat Rh1+ then ...). Black legal replies: c6-c5, g5-g4, king moves h4,h6,g6,Kg4?? h4 attacked? after Kg2, Kh4, Kh6, Kg6, Kg4 (attacked by nothing? Rg1 attacks g4, so no). So Kh4, Kh6, Kg6, c5, g4. If 32...Kh4 33. Rh1+ Kg3?? wait 33.Rh1+ Kg3 34... hmm king g3 next to white king g2? Adjacent — illegal. So Kh1+... after 32...Kh4, 33. Rh1#? King h4: squares g3 (adjacent to Kg2 — illegal), g5 (attacked by Rh1? h1 attacks h-file... no g5 not), h5, h3(attacked by h2 pawn? h2 attacks g3 only... pawn h2 attacks g3. h3 attacked by Rh1! yes rook covers h-file). So after Rh1+ king goes g5 or h5. Not mate. Hmm but 33.Rh1+ Kg5 34.Rh5+? Kxh5? No, rook protected? Rook h5 — king takes? h5 defended by? nothing. Bad. Alternative after Kh4: 33. Nc5? or Kf3 trapping: 33. Kf3!? then Kh3 (h3 attacked by h2 pawn? pawn h2 attacks g3. h3 not attacked. Kh3, Kh5, Kg5). Hmm. Actually maybe straightforward plan: g4+ then Kh6/Kg6/Kh4, and h4 creates mating net. Let's evaluate 32. g4+ Kh6 33. Kg2 then black king h6 only squares h7? g6? Wait after g4+ Kh6, king h6 squares: h7,g7,g6(escaped),h5(back). Then 33. Kg2 Kg6 hmm. Maybe better: 32. g4+ Kg6 33. Kg2! then king g6 can move f5? attacked by g4 pawn yes... squares: f6? wait after Kg2, from g6: f5(attacked by pawn g4), g5? pawn g5 is there? No black pawn moved? Black pawn still g5... wait black king on g6, pawn on g5, so king squares: f7? no wait king can go f7,g7,h7,f6,h6,f5? hmm many squares. King can run: Kf6, Kf7, etc. Rook g1 pins nothing. Hmm, but with such material edge, simplest winning: just take g5 pawn eventually, then promote a pawn. Very easy win regardless. But mate hunt is nice. Let's find forced mate maybe: 32. g4+ Kh4 33. Kf2!? threat Rh1#. King h4 moves: g3 attacked by h2? h2 attacks g3 yes and Kf2 covers g3. h3 attacked by Rh1 later... currently king h4 could go h3 (attacked by Rg1? no), so Kf2 then Kh3 34. Rg3+? Kxh2?? h2 pawn... Kh3 attacked by rook g3 check, king takes h2? h2 defended by Kf2? No, f2 not adjacent to h2... g2 pawn defends h3! Pawn g2 attacks f3 and h3. So Kh3 illegal after g4+. So after g4+ Kh4, king squares: g3 (g4 pawn defends? no; h2 pawn attacks g3; also Rg1 no; K? White king c1 far). g3 attacked by h2 pawn. So Kh4's legal moves on next: g5, h5, h3(attacked by g2 pawn? g2 attacks h3 yes, illegal). So Kh4 then 33. Rh1+! Kg5 (or Kh5) 34. Kf2? Hmm then Kg4?? attacked by... Alternatively 32. g4+ Kh4 33. Kg2 threatening Rh1#: king h4 must move; Kh3 illegal, so Kg5/Kh5/Kg4?? attacked by Rg1. Kg5 — then 34. Rh1+? Kg6/Kg4(attacked)... 34. Rh1+ Kg6 35. Rg1+ Kf6?? wait g5 pawn still on g5! After Kh4, black king can't go g5 if own pawn there. Right! Black pawn g5 still exists. So after g4+ Kh4, king squares: h3 (illegal, g2 pawn), g3 (illegal, h2 pawn... wait h2 pawn attacks g3 yes), g5 (own pawn), so only Kh5! Back to h5? h5 attacked by g4 pawn! So actually g4+ — if Kh4, then... no wait it's black's move after g4+, they choose. Kh4 would allow Rg1... hmm king on h4 with escape only... let me recheck: after 32. g4+, black king on h5. Options: Kh6, Kh4, Kg6. If 32...Kh4: white plays 33. Kg2 (or Kf2). King h4: h3 illegal (g2 pawn), g3 illegal (h2 pawn), g5 own pawn, h5 illegal (g4 pawn attacks h5). So king has NO moves! Then black must move pawn: c6-c5 only? g5 pawn: can it move? g5 blocked? g5 pawn can't move forward — g4 occupied by white pawn. So black plays c5, then 34. Rh1#. Mate! Or if black only move c5 earlier. Actually after 32. g4+ Kh4, black's only legal move might be c6-c5 (zugzwang-ish). Then Rh1#. If 32...Kg6: 33. Kg2 (threatening Rf1? no). King g6: squares f7,g7,h7,f6,h6,f5(illegal, g4 pawn), g5 own pawn... many. Hmm. Then 33...Kf6/Kh6/Kf7 etc. If Kh6 34. Rh1+? Kg6... hmm not immediate. If 33...Kf6 34. Rf1+ Kg6/Ke7... king escapes to center. But material still crushing; we can hunt with king: eventually Kf3 etc. Still easily winning. If 32...Kh6: 33. Kg2, king h6: h7,g7,g6,f6,h5(illegal? g4 attacks h5 yes),g5 own pawn. 33...Kg6 transposes, or Kh7 34. Kf3? Hmm. But wait — check 32. g4+ Kg6 alternative for White: maybe 33. h4!? then Kh6 34. Rf1... Actually simpler: after g4+ Kg6, 33. Kg2 Kf6 34. Kf3? wait but black could also push c-pawn. With huge material, we can also just win g5 pawn by attacking: e.g., Rf1... hmm. Alternatively stronger first move: 32. Kg2!? threatening Rh1# ideas but black king h5 free: g6 etc. Or 32. Kf2, intending Kg3 covering king-side: then black king can't approach. Honestly g4+ creates mating net around h-file. Let's analyze 32. g4+ Kg6 33. h4!? (threat Rf1?? no, threat g5? hmm) — after g4+ Kg6 33. h4, black king h6? h5? Let's see: threat is 34. Rh1? no king on g6. Alternative 33. Kg2 Kf6 34. Kf3!? black king runs: Ke5 etc. Then 35. Rg... we can give checks: Rg1 hits g5 pawn pin? King f6 in front? Actually, with up a rook and knight and 6 pawns vs 1, anything wins. Let me pick g4+ as strongest practical, and handle: Line A: 32...Kh4 33. Kg2 (zugzwang) c5 (only move? also g5 can't move, king stuck) — wait check g5 pawn: on g5, moves to g4? Occupied. Captures: g5xf4/h4? Nothing on f4/h4. Yes only c5. 34. Rh1#. Hmm wait, is 33. Kg2 needed, or is mate available immediately after 32...Kh4 via 33. Rh1+? Kg5 not possible (pawn there)... 33. Rh1+ Kg5? No, pawn g5. Kh5 illegal (g4 pawn), h3 illegal, g3 illegal... wait g3 attacked by h2 pawn only — yes h2 pawn attacks g3. So 33. Rh1#! Let me verify: after 32. g4+ Kh4, 33. Rh1+ — king on h4. Escape squares: g3 (attacked by h2 pawn — white pawn h2 attacks g3, yes), g4 (occupied by white pawn? King could capture g4! Is g4 defended? Rook moved to h1, so g4 defended by... nothing? Pawn h2? No, h2 attacks g3. Rook g1 was defending g4 but it moved to h1. Hmm! So Kxg4 possible). Wait also is king in check from Rh1 — yes. Kxg4 legal if g4 undefended. After Rh1+, g4 defended by... nothing. So Kxg4! escapes. So need 33. Kg2 first, keeping rook on g1 guarding g4. After 33. Kg2, black king h4 has no moves (h3 - g2 pawn... wait now white king on g2; g3 adjacent to Kg2 — illegal anyway; also h2 pawn attacks g3). Black plays c5. 34. Rh1#: king h4, Rh1 check, escapes: g3 (adjacent Kg2 illegal + h2 pawn), g4 (defended by Kg2? g2-g4 not adjacent. Rook on h1 doesn't cover g4. Hmm! Kxg4 again!). Wait after 33. Kg2 c5 34. Rh1+ Kxg4?? — is g4 defended? Kg2 defends f1,f2,f3,g1,g3,h1,h2,h3. Not g4. So Kxg4 escapes and then king is out! Ugh. So instead after Kh4, play 34. Kf3? Let's think: after 32. g4+ Kh4 33. Kg2 c5 (forced) 34. Kf3!? then king h4: h5?? attacked by g4 pawn... king squares: h3 (attacked by g2? no; rook g1? no; Kf3? no, f3 covers e2..g4... h3 not covered). Hmm Kh3 possible? h3 attacked by... nothing? White pawns g2? g2 attacks f3,h3 — g2 still there! Yes g2 pawn attacks h3. So Kh3 illegal. King h4 squares: h3 illegal (g2 pawn), h5 illegal (g4 pawn), g5 own pawn, g4 — attacked by Kf3! and Rg1! So king completely stuck again. Black must move c-pawn again: c4. 35. Rh1#. Check: king h4, Rh1 check, escapes g4 (attacked by Kf3), g3 (attacked by Kf3? f3 covers g3 yes... wait also h2), g5 own pawn, h3 attacked by g2 pawn and Rg1? h-file by Rh1. So mate! But black's c-pawn: 33...c5 34. Kf3 c4 35. Rh1#. Also black might have 34...c4 earlier — fine, then 35. Rh1# still. Actually even better: after 32.g4+ Kh4 33. Kg2 (any pawn move) 34. Kf3 (pawn move) 35. Rh1#. Great, mate in that line. Alternatively 33. Kf2!? instead of Kg2: after Kh4 33. Kf2 same-ish. Keep g1 rook guarding g4 though. 33. Kg2 fine. Line B: 32. g4+ Kh6 33. Kg2 (zugzwang-ish): king h6 squares: h7, g7, g6 (Rg1 attacks g6? No, g5 pawn blocks! Rook on g1, black pawn g5 between. So g6 not attacked), h5 illegal (g4 pawn), g5 own pawn. So Kh7/g7/g6. If 33...Kg6 then king active. Hmm. 33...Kh7 34. Kf3? Black king still free: Kh8, etc. Then it takes longer but we can bring rook: e.g., Kg2 then... Since black king can shuffle h6-h7-g7-g6, white improves: Kg2, Kf3, then maybe Rh1+ ideas? Let's see plan vs Kh6: 33. Kg2 Kh7 34. Kf3 Kg6? hmm 35. ... not forced mate yet. But White could also play 33. h4!? after 32...Kh6: threat? 34. Rh1? no king h6: Rh1+? not check. Threat 34. Kg2 then Rh1#? King h6: h5 illegal, h7, g6, g7 free. Alternatively, maybe 32. g4+ Kg6 33. h4!? threat 34. h5+? no... threat Kh3?? hmm. Simplest robust plan regardless: keep options. Even if king runs to f6/e6, we have R+N+5 passers... wait we have pawns a2,b2,c2,f2,g2,h2 (g2->g4). Knight b7 far. But we can win slowly: march king, use rook to harass. Actually better idea: after g4+, if king goes toward queenside/center (Kg6->f6 etc.), black king abandons g5 pawn; then Nxg5? No wait knight b7 to g5 takes long. Rook can win g5 pawn: Rf1 then Rf5? Hmm. Alternatively choose 32. Kg2!? first, threatening nothing immediate but black king h5 can't move to g4 (Rg1), so squares: h6, g6, h4!, g5?? own pawn. 32...Kh4 33. Rh1+! Kg3?? adjacent g2 illegal; so Kg5? pawn there... King h4 after Rh1+: escapes g4 — Rg1 moved... ugh again Kxg4?? wait after 32. Kg2, if 33. Rh1+ Kxg4 — g4 defended by Kg2? No. Hmm, same issue. But wait after 32. Kg2 Kh4, white plays 33. Rh1+!? Kxg4?? 34. Rh4+?? no wait 34. Rg1+? Kf4/Kh5/Kh3?? Kg1 check from... king g4, Rg1+ then Kf4, Kh5, Kh3(h2 pawn? h2 attacks g3, not h3. Kh3 attacked by Rg1? no... h-file? Rook on g1 doesn't attack h3). King escapes. So that fails. OK: 32. g4+ it is — if king stays (Kh4), forced mate soon; if king runs (Kg6/Kh6), we continue Kf3-ish, Rf1... Actually vs running king, maybe better plan: 33. h4 (after g4+ Kg6 33. h4!? or after Kh6 33. h4), creating more net: pawn on h4 attacks g5! Then g5 pawn is attacked and pinned-ish? If gxh4?? then... black pawn g5 could capture h4 if... no wait after h4, black pawn g5 attacked by h4 pawn; if black king not defending g5... Actually gxh4? Black pawn g5 captures h4: possible if h4 is on g5's diagonal — black pawn g5 captures f4/h4? Black pawns capture toward rank 1 diagonally: g5 captures f4 or h4. Yes! So h4 hangs to g5xh4. If defended: after gxh4, then king h5?? Let's see: after 32. g4+ Kg6 33. h4 gxh4?? 34. Kg2 and pawn h4 falls to... Kg2 then Kxh3?? hmm. Black king g6 defends? g5 gone, h4 defended by king g6? Not adjacent (g6 to h4 no). So gxh4 loses pawn, then 34. Kf3?? hmm white king walks to take h4: Kg2... meanwhile black king free. Material still trivially winning. Honestly with +12 material, any reasonable move wins. Choose g4+ — most forcing, sets up mate net. Wait — also consider 32. f4!? or Nd6-f5 ideas: Nd6 then Nf5+ forking king and g-pawn? Nd6: from b7 to d6 then f5+ hits h4? Nf5+ attacks h4, g7... king h5: Nf5+ fork king and... Nf5 attacks h4 and g7, h6. Not g5. Hmm. Nd8-f7+!? Nd8 then Nf7+ Kg... Nf7 checks h... f7 knight attacks h8, h6, d8, d6, e5, g5! Nf7+ would fork king h5?? f7 attacks h6/h8 not h5. Hmm no. g4+ is clean. Also creates passers later. Go g4+. Quip: playful response to their "foreclosing on bishop" line.

32. g4+ sets up a mating net — if the king retreats to h4, it has no squares (g4, h3, g3 all covered), and mate follows shortly.

Black in check: Kg6, Kh6, Kh4. White has Rg1. If Kh4?? Rg4#? King h4, pawn g4, pawn h2... Rg4+ is check, king h4... actually Kh4 walks into g4 pawn? Pawn g4 attacks f5 and h5, not h4. Kh4 attacked by Rg1? Rook on g1, king h4 — rook checks along g-file only. Kh4 attacked by pawn g4? No. Pawn h2 attacks g3. So Kh4 is legal. Kg6: attacked by g4 pawn? Pawn g4 attacks f5, h5. No. Rook g1 checks along g-file — g6 is on g-file, so Kg6 is illegal? Rook g1 attacks g2-g8? g-file: g1 rook, g4 white pawn blocks! Rook g1 up: g2, g3, then g4 pawn — blocked. So g-file above g4 isn't attacked by rook. Wait, Rg1 attacks g2, g3, g4(pawn, can't pass). So g5, g6, g7, g8 not attacked by rook. But g5 is occupied by black pawn. Check currently from pawn g4? Pawn g4 attacks f5 and h5 — so king h5 in check. Legal moves: Kg6, Kh6, Kh4. Kh4: attacked by Rg1? No (g-file blocked by g4). Attacked by anything? h2 pawn attacks g3. g4 pawn attacks f5,h5. So Kh4 is legal. Then threat: White plays... if Kh4, is White threatening Rg4#? Rook g4 gives check along rank 4? King h4 — Rg4+ checks h4 along rank. King escapes: h3? h3 attacked by Rg4? No. h2 pawn occupies h2. King h4 to h3: legal? h3 attacked by anything? No. So not mate immediately. Kh6: then White? Kg6/Kh6 both fine. But which is best? After Kh4, White can play Rg4 pinning? Actually after Kh4, White might play f3 or Kg2. Also Kh4 allows Rg4+ and then Kh3? h2 pawn... wait after Rg4+, king can't go h3 if h2 pawn... h3 empty, h2 pawn attacks g3 only. Kh3 legal. Then Rg3+!? Kg4... hmm. Alternatively Kh6: rook still blocked by g4 pawn. White then maybe Kg2, then f3 with king marching? White up 12 pieces anyway; it's hopeless-ish but let's just play best defensive. Kh6 vs Kh4: Kh4 keeps rook's g-file blocked from both sides? Rg1 blocked by g4 pawn regardless. With Kh4, White can push? White pawn h2 could become passed after king takes? King h4 attacks h3? Actually king on h4 attacks h3, g5, g3. Consider Kh6 then h4+? No white h-pawn on h2. If White later plays h3 threatening? Let me think: Kh6, then White h3 with king coming, then g5+ maybe. Actually with king h6, White pawn g4 can't advance due to g5 black pawn? g4-g5?? blocked by black pawn g5. hxg5? h2-h3 then h4 then hxg5+ Kh... So White h-pawn will take g5 giving check perhaps. Better: Kh4 attacks... hmm, Kh4 then White h3! and g5 pawn still. Actually after Kh4, h3 attacks the king? h3 pawn attacks g4. King h4 to... Let's just evaluate: Kh4 might allow stalemate traps? White Kc1 far away. Black king h4, pawns c6, g5. If king h4, g5 is defended by king. White rook g1 can't do much. White h2 pawn can advance to h3 then king on h4 can't capture? King h4 attacks h3, yes can capture when pawn moves h2-h3? After h3, pawn attacked by king, king can take hxh3? King h4 takes h3 — legal if not defended. Then black gets a pawn. Hmm. Kh6: black king h6, g5 defended. White h3 then king h4... Actually maybe Kh6 is safer, keeping distance. But Kh4 attacks g4 pawn? King h4 attacks g4? No—h4 to g4 adjacent yes! Kh4 attacks g4. But g4 is defended by Rg1 (g-file: g1 rook to g4? g2, g3 empty, yes rook defends g4). And h2 pawn? No. So king can't take g4. Kh4 allows Rg4 pinning? Rg4 pinning nothing... Rg4 attacks g5 pawn? Rook g4 attacks g5, defended by king h4? Wait if Kh4, g5 defended by king. Rg4 attacks g5, Kxg4?? can't—rook defended? Rg4 defended by nothing... Rook g4 attacked by king h4, defended by nothing else (h2 pawn doesn't defend g4... pawn h2 attacks g3). So Rg4?? Kxg4! Black wins rook! Wait but is Rg4+ check? Rook on g4, king on h4 — check along rank 4. King must respond: Kxg4 captures rook — is rook defended? Rook g4 defended by... h2 pawn? No. So after Kh4 Rg4+?? Kxg4 wins the rook. So White wouldn't play that. After Kh4, what can White do? Kg2 heading toward? White pawns a2,b2,c2,f2,h2. King g2 then h3, g4 protected... Black king h4, White king g2-h3 then black king can take h2? King h4, h2 pawn: if Kh3+? Let's not overanalyze. Kh6 seems safer—stays far, avoids rook tricks. Actually with Kh6, White could play Kg2, then f3, then king approach. Meanwhile black king h6, White h3! threatens h4 then hxg5+ discovered... h3-h4 then hxg5+ Kh7? g5 pawn... King h6, pawn takes g5 with check (pawn g5 attacks... white pawn on g4 captures to g5, black pawn g5 gone). Check from pawn g5? White pawn g5 attacks f6, h6 — yes check. Kh7, then h4, h5... endgame lost anyway. Kh4 vs Kh6: with Kh4, king closer to capture pawns potentially. Black king h4, after Kg2 h3 threatening hxg5? h3 pawn... hmm king h4 then hxg5+ Kxg5. Honestly both lost-ish; pick Kh4 to be active, going after h2 pawn. King h4 then White must watch h2. E.g., 32...Kh4 33.Kd2? c5... Black can maybe make rook pawns race? King h4 eyes g3? No. Actually could there be stalemate danger for White? No, White has many pawns. I'll play Kh4 with a cocky quip.

**Kh4** — hooking onto the g4/h2 pawns. With the g-file plugged by White's own pawn, the rook is just scenery, and if the rook ever dares Rg4+ it's simply *Kxg4*.

Black king on h4 with pawns c6 and g5. White: Kc1, Rg1, Nb7, pawns a2 b2 c2 f2 g4 h2. Up huge. Need to avoid stalemate and mate carefully. Black king h4: legal moves? Black to move after our move. Currently Black's king can go... after our move, Black king moves: g3, h3, g5(pawn? g5 is own pawn... no, g5 is black pawn). Black pieces: c6, g5 pawns. Let me find mate. Check candidates: Rg3? No, that lets king... Rg3 attacks nothing? Rook on g3 gives check along rank 3? King on h4, Rg3+ would be... rook on g3 attacks h3, g-file. King h4: check from rook on g3? No, rook at g3 attacks h3 not h4. Not check. Nd6? Nc5? Let's think mate: threat Rh1#? King h4, if rook goes to h1, check along h-file; escape squares g3, g5(own pawn). King could go g3? Rook on h1... g3 attacked by rook on g-file? No, rook on h1 attacks h-file and rank 1. Kg3 escapes. Also need g4 pawn covers g3? White pawn g4 attacks f5 and h5. Kg3 not covered. So Rh1+ Kg3. Try Nd8 planning... let's aim: g5 pawn shields. Candidate Nc5 threatening? Nd6 threatens to take... Nc6 pawn. Mate ideas: Kd2 slow. Let's do f3!? Pawn f3 attacks g4... king h4: after f3, king's squares: g3? attacked by f2? No pawn moves. Kg3 possible. Not forcing. Best: Rg3! Threat: rook on g3 covers g3 and controls g-file... King h4 can't move to g3 (occupied by rook... it can capture? No white rook on g3 would be adjacent, king can capture unless defended). Not check, so Black moves g5 pawn maybe. Actually consider immediate Nc5 with threat Rh1#? King h4 escape: Kg3, Kxg4? g4 defended by... pawn? f-pawn at f2 doesn't defend g4. Kxg4 possible after Rh1+. Try mate plan: Rg3 then ...anything, then Rh1#? After Rg3, Black's moves: Kg5? No, king h4 to g5 blocked by own pawn? g5 occupied by black pawn, can't. King h4 moves: h3? attacked by g4 pawn? No, g4 pawn attacks h5, f5. h3 free. g3 attacked by rook. So after Rg3, Black plays Kh3 or pawn moves (c5, g4? g-pawn g5 can push g4? No g4 occupied by white pawn; gxh4? no; g5xh4 illegal). So c5 or Kh3. Hmm, stalemate risk? After Rg3, king has h3, so fine. Then Rh1+? No wait if Kh3, then Rh1#? King h3, Rh1+ check; Kg3... g3 attacked by rook on g1? Rook moved to h1. Hmm after Rg3 Kh3, rook is on g3, not g1. Let me think simpler: Nd6 and Nc5 don't matter much; the mating attack: rook on g-file, pawn g4. Black king h4. Ideal mate: Rh1# needs g3 covered. f3!? covers g4... hmm pawn f3 doesn't cover g3. Plan: Kd2 slow. Plan: Rg3 covering g3? Rook on g3 covers g3 itself (king can't move to attacked... king can't move to square occupied... it's occupied by rook, could capture if undefended — rook on g3 defended by g4 pawn! g4 pawn attacks f5 and h5, not g3. So rook undefended; Kxg3 possible). Hmm. What defends g3? Pawn h2 attacks g3! Yes! h2 pawn defends g3. So Rg3 is defended by h2 pawn. Then after Rg3, Black king stuck: h3, g3 (rook defended), g5(blocked). So Black has Kh3 or c5. After Rg3 Kh3: then ... Kh3. White: Rh1#? Rook g3 to... Rh1+ no. After Kh3, White can play Rg... hmm, king h3, White rook g3 adjacent. Black king escapes: Kg4?? attacked by rook g3 (g-file? g4 above rook g3, yes g-file) and g4... g4 is own white pawn, occupied. Kg2 attacked by rook. Kxg3 defended. h2 pawn... Kh2? attacked by rook on g3? No, rook on g3 attacks h3, g2... g3 rook attacks rank 3 and g-file. Kh2 attacked by... nothing? h2 is white pawn square? h2 occupied by White pawn. King can't move to occupied square (except capture). So after Rg3 Kh3, Black king on h3 has no escape squares — that's why Black wouldn't play Kh3... wait Black just moved there. It's White's move. Position after 33.Rg3 Kh3: White to move, mate in 1? Kg... hmm. Rh1+ Kg2?? attacked by rook g3? Rook moved to h1. King h3 escape: g2 (attacked by rook g3? rook left g3 to h1). Ugh. After 33.Rg3 Kh3 34.??? mate: Nc5 no. 34.Rg... Let's see, Black king h3, adjacent white pawn h2, white rook g3, white g4 pawn. White mate ideas: Rg... rook to g3 is already. Move rook away loses tempo. 34. Nc5 then? Or 34. Kd2 — Black king has no moves! Black only pawn moves: c5, g-pawn can't move (g5xh4 no, g4 blocked by white g4). So after Rg3 Kh3, Black king trapped, but Black can push c5. Not stalemate. Alternative: 33. Nc5 with zugzwang ideas? Too slow maybe but we're up massively; just avoid blunders. But let's find forced mate. Let's evaluate 33. Rg3: - Black: c5 (pawn), Kh3. (Kxg3 illegal — defended by h2 pawn... wait does pawn h2 defend g3? h2 pawn captures on g3 and g1. Yes defends g3. So Kxg3 illegal.) - 33... Kh3 34. Rg... hmm what mates? 34. Nd6 c5... Let me look: after Kh3, king on h3. White rook g3 controls h3? No, king is on h3 adjacent. Check from rook? Rook g3 attacks h3 along rank — wait rook on g3 attacks g3's rank: f3, e3, ..., h3! Yes rook attacks h3! But king can't be in check on Black's turn... After 33.Rg3, is Black king in check? Rook g3 attacks h3 and h4? Rook on g3 attacks along rank 3 (including h3) and g-file. King on h4 — not on rank 3 or g-file. Not check. OK. If 33...Kh3, that's moving into... h3 attacked by rook, illegal! So Black king has NO moves after 33.Rg3: g3 illegal (occupied+defended), g5 blocked, h3 attacked by rook, h5 attacked by g4 pawn, g4 occupied by white pawn. Black's only moves: c6-c5 and g5xh4?? no, g5-g4 blocked. So c5 only... then after c5, Black only pawn c-pawn moves until... Actually if Black plays c5, then Black still has pawn moves c4? White pawn c2 can capture? Let's not worry. But wait — is Black stalemated right now if pawn moves exist? Black has c5. Then White gets free tempo. After 33.Rg3 c5, White to move, mate in? Black king h4 boxed. Mate in 1? Need check covering g3, h3, h5, g5(covered? king can't go to own pawn square), g4 (white pawn). Rook g3 covers g3... king h4 in check needed. Rh... rook on g3: move along rank? 34.Rxh... 34. Rg... hmm. King h4 adjacent: rook could give check via 34. Rg... rook stays on g-file gives check to h4? No. Knight check: Nf3+? No knight at b7. Nd6-f5+! 34.Nd6 then Nf5+ next. Or immediately: knight b7 to... Nc5-e... squares from b7: a5, c5, d6, d8. Then from d6: f5+! f5 checks h4? Knight f5 attacks h4, yes! So 34.Nd6 threat Nf5#, and Black's only moves: c4 (pawn), then 35.Nf5#? King h4: knight f5 checks; escapes g3(covered by rook? rook on g3 yes), h3 (rook), h5 (g4 pawn), g5 own pawn. Mate! But Black could... after 34.Nd6, Black plays c4 35.Nf5#. Also 34...c4 then c3 35... whatever, Nf5 mates. Even faster: does White have mate in 2 differently? Fine. Actually check 33.Rg3 stalemate concerns: Black has c5, so no stalemate. Good. Alternatively 33.Nd6 (threat Nf5+ then... Nf5+ Kg... king h4, knight f5+ — escapes: h3! Rook g1 covers h1 not h3. h3 free. So Nf5+ Kh3 not mate yet). Rg3 plan is cleaner. But also check 33.Rg3 c5 34.Nd6 c4 35.Nf5# — verify knight path: b7-d6, then d6-f5, yes. Knight on f5 attacks h4, g3, e3, d4, d6, e7, g7, h6. Check to h4 ✓. King escapes: h3 — attacked by rook g3 ✓ covered. g3 — occupied by rook, defended by h2 ✓. h5 — attacked by g4 pawn ✓. g5 — own pawn. Mate ✓. Even simpler: after 33.Rg3 c5, mate in 2 with Nd6. Also maybe 34. Rh3+? No, rook g3 to h3 — 34.Rh3+ Kg... king h4, rook h3 check, Kxh3? Rook h3 undefended? Defended by nothing (h2 pawn defends g1/g3... h2 pawn attacks g3? h-pawn captures diagonally forward: h2 attacks g3. So h2 doesn't defend h3). Kxh3 no wait rook checking adjacent can be captured. Bad. So best move: 33. Rg3. Quip.

Black is in serious danger: Kh4, White can play Rh3+ forcing mate soon. Black king on h4, pawns g5, c5. Rh3+ Kg5? Then... let's check mate options. White: Kc1, Rg3, Nb7, g4. Black: Kh4, c5, g5. Rh3+ Kxg4?? No, king can't capture defended... h3 square, rook protected by g2? No, g-pawn is on g4, so g3... wait rook on g3, pawn g4, king h4. Rh3+ — is h3 protected? Not by anything except... king can't reach h3 from h4? Kh4 to h3 is adjacent — capture Rxh3? Kh4xh3, is h3 defended? Pawn g2? No, pawn is on g4. Nothing defends h3. Wait but Rh3+ Kxh3?? King captures rook. Is h3 adjacent to Kh4 — yes. So Rh3+ loses the rook? Unless protected. Nothing protects h3. So Rh3+ is bad. Alternative: mate threats. Black king h4, g5 pawn blocks g5 flight... Black king on h4: squares h5, g4(covered by pawn g4? g4 pawn attacks f5,h5), g3(occupied by rook), g5(own pawn), h3. Actually g4 is occupied by White pawn — king can't go there. h5 attacked by g4 pawn. So black king only has h3 and can capture g4? Kh4xg4: is g4 defended? Rook g3 defends g4! Yes, Rg3 on g-file defends g4. So Kxg4 illegal. So black king has escape h3 only if rook moves? Black king currently: moves h5(illegal, g4 pawn attacks), g4(occupied/defended), g3(rook), h3(free). So black is nearly in zugzwang-ish but has pawn moves c5-c4 etc. Mate idea: Rg1? Then threat Rh1#? No, king on h4. If we play Nd6 or something, black plays c4. Then K moves? Actually black king can only move to h3. Black currently is fine because c-pawn moves. Mate in how many? White to move. Try Nxc5? Black plays Kh3... then? White: Nd3? Let's think: after 34.Nxc5 Kh3, white can play Kd2? Hmm. Better: aim for mate. Black king only has h3. If we control h3 with a piece while keeping g4 protected and rook controlling g-file, then mate. Idea: Nd6 (heading f5? no...). Knight on b7: squares a5, d6, d8, c5. To attack h3, knight needs to reach... knight attacking h3: from f4, g1, g5, f2. From b7 far away. Alternatively rook: if rook stays on g-file, threat is... K can't move to g-file. Rook on g3, king h4: if we remove black's pawn moves and black must move king, Kh3 attacks... rook on g3, Kh3 attacks rook. Then rook can move to g1 with check? No. Alternative mate: h3+ by pawn h2-h3?? That's legal! h3 pawn push — wait pawn on h2 can advance to h3? h3 is empty, yes. But it's not check... actually pawn h3 would attack g4, not h4. But it takes away h3 escape square! After h3, black king h4: moves? h5 (attacked by g4 pawn? pawn g4 attacks f5 and h5 — yes h5 illegal), g4 (defended by rook and now pawn h3), g3 rook, h3 occupied by pawn, defended by? Pawn h3 defended by nothing... Kh4 can capture h3? No, h3 is occupied by White pawn; king could capture Kxh3 if undefended. Kxh3 — is h3 defended? Rook g3 doesn't defend h3... rook on g3 attacks g-file and rank 3: h3! Yes, rook on g3 defends h3 (same rank). So after h3, Kxh3 illegal. So after 34.h3, black king has NO moves! Black must move pawns: c5 or g5. g5 can't move (g5-g4 blocked). c5-c4 available. So 34.h3 c4, then 35... black still has pawn moves c4, c3, c2? c2 blocked... c4-c3, c3-c2 blocked by c2 pawn? c2 is White pawn, so c3-c2 blocked. So after c4-c3, pawn can't move. Then black king in check? Not yet. But wait — is h3 a good move? After 34.h3 c4, we need mate. Black king stuck. Then white can bring king or knight. Knight b7 can reach... eventually mate: e.g., bring king over? Mate pattern: king confined to h4, need check on h-file or g-file or diagonal. Rook already on g3. If rook goes h3... no. Actually with king having no moves, any check that covers h4 escape... check along h-file: rook to h-file? Rook g3 to h3 — defended? Kxh3 no, king can't capture defended rook... but check: Rh3+?? rook on h3 gives check? Rook on h3 attacks h4 — check! King can't capture (rook defended by pawn h2? no, h2 moved to h3... rook on h3 defended by g... hmm). After 34.h3 c4 35.Rh3?? No wait, h3 occupied by our own pawn. Rook can't go there. Let's plan: 34.h3 c4 35.Kd2 c3+ 36.Kxc3 (or Kd3) Kxh3?? no wait after black king has no moves and pawns exhausted... after 35...c3+ 36.Kxc3 black has no moves at all — stalemate? Black king h4: h5 illegal (g4 pawn), g4 defended, g3 rook, h3 defended by rook and... pawn h3 there. g5 pawn can't move (g4 occupied by white pawn — could g5 pawn ever move? g4 is White pawn, blocked). So after c3 is captured, black stalemated! Bad. So avoid stalemate. Plan: mate with knight. Knight to attack... king on h4, knight check from g6 or f5 or g2. Knight b7 → a5 → c4?? c4 has pawn after c4. Route: b7-d6-f5+? From d6, Nf5 gives check? Knight f5 attacks h4! Yes Nf5+ checks king on h4. But Nf5 — g5 pawn could capture Nxf5? Pawn g5 captures on f4 and h4 — not f5. King on h4 could... after Nf5+ king has no moves — mate? King h4: h5 (g4 pawn attacks — illegal), g4 (rook + pawn h3... rook defends g4 — illegal), g3 rook, h3 pawn defended by rook — illegal. Check from f5, escape squares all blocked → MATE! So plan: 34.h3 c4 35.Nd6! (threatening Nf5#) — black in check? No. Black must respond: c3 (c4-c3), then 36.Nf5#? Wait knight needs d6-f5, two moves: 35.Nd6 c3 36.Nf5#. Check: after 35.Nd6, black's moves: c3 only (king has none, g5 blocked). 36.Nf5# mate. But careful: at 35...c3, is c3 check? White king c1 — c3 pawn attacks b2 and d2, not c1. Fine. Alternatively faster? 34.Nd6 c4 35.Nf5+ — wait Nf5 check, king h4, but h3 available? King h4→h3: attacked by Nf5? Knight on f5 attacks e3,g3,e7,g7,h4,h6,d4,d6 — not h3. So Kh3 escapes. Then king on h3... So h3 pawn push first is key. Also check 34.h3 immediately: black responses? King no moves. c5-c4 only. Good. Actually could there be even faster: 34.Rg1 waiting? 34.h3! c4 forced, 35.Nd6 c3 36.Nf5#. Mate in 3. Also verify after 34.h3, black king truly has no moves: g5 pawn belongs to black, king can't move there anyway. Yes. Edge: after 34.h3 c4, could black... only c4. Then 35.Nd6 c3 (forced), 36.Nf5#. Also 35...c3 36.Nf5#? Knight d6→f5, check to h4, escapes: none. Mate. But also must confirm black has no in-between: after 35.Nd6, black: king stuck, g5 stuck, c4-c3 only. Yes. Alternatively 35.Nxc4?? then no mate quickly. Stick with Nd6. Play 34.h3 with quip.

Yes! f2 pawn defends g3. So king can't take rook. Black king h4 legal moves: none (g3 defended, g4 pawn, h3 pawn, h5 — is h5 covered? No White piece attacks h5). So h5 is free... wait does Black king have any legal move? h5 — attacked by anything? Nb7 could... N b7 to... no. g4 pawn attacks f5 and h5! Yes, g4 pawn attacks h5.

Nearest mate: Rg3 to... If we move rook, king gets g3? No, h5 covered, g3 vacated — but then Rg2+ would check? Rg3 moving to g2 keeps g-file control, no check on h4. Need check on h4 or diagonal. Mate ideas: Nf6 doesn't exist (knight at b7). Knight to... h4 check from knight: knight checking h4 from f5, g6... Nf5? From b7 no. Bring knight to g2/f5... Nc5 then Ne6... slow. Simplest: Rg3-h3?? illegal? Rh3 pawn there. Rf3? Then Black plays Kg4?? no, pawn g4 defended by h3 and f2... wait g4 is White's own pawn; Black king going to g4? g4 occupied by White pawn — capture? Kg4 attacked by h3 pawn and f2? h3 pawn attacks g4. So after Rf3, Black king... h4 king: moves to g3? Rf3 vacated g3, is g3 attacked?

So g5 pawn can't move! c4 pawn: c3 possible, or captures d3/b3 (empty). So Black can only push c-pawn: c3, then c2... after c2, then Black runs out — stalemate danger if c-pawn gets captured or blocked. So count Black's moves: c3, then cxb2? If c3, then c2 (if allowed, c2 blocked? White pawn c2... c2 square — White pawn is on c2! Board shows c2 White pawn. So black c4 pawn: c3 blocked? c3 empty, so c3 possible; then c2 occupied by White pawn — pawn can't advance to occupied square, but can capture b2? White pawn on b2. So c3 then cxb2 or cxd2... d2 empty after. Actually after c3, captures: b2 (White pawn) or d2 (empty, no capture). So Black has c4-c3, then cxb2. Then Black is out of pawn moves → stalemate if we can't mate in time! So White must mate within ~2 moves or accept stalemate/draw? Black: 34...c4 just played. Black moves remaining: c3 (move 36...), cxb2 (move 38...). So White has moves 35, 36, 37, 38 to mate — actually after Black's cxb2, Black has no moves; if not mate/check, stalemate. Also Black's b2 capture... after cxb2, White could... but stalemate applies only if Black has no legal move and not in check. So mate by move 38 at latest, or ensure Black king... alternatively we could give Black a move by not blocking? White could also create flight squares to avoid stalemate, but easier: find mate. Mate in 3? Knight route to f5 or g2... Nf5 checkmates (g3 f2-pawn, h5 g4-pawn, knight f5 protected? doesn't matter, king h4 adjacent squares: f5 not adjacent... wait king can't capture f5 anyway since not adjacent to h4? f5-h4: distance 2 files? f to h = 2, so not adjacent. Knight on f5 checks h4? Knight on f5 attacks: h4, h6, g3, e3, d4, d6, e7, g7. Yes attacks h4. King h4 moves: g3 (f2 pawn), g4 (White pawn, can't capture — is g4 defended? h3 and f2 defend g4, yes), h3 (White pawn, defended by Rg3? rook on g3 attacks h3. Also can't capture own... it's White pawn; capture Kh3? g4-adjacent... h3 defended by rook g3 and g4 pawn). h5 attacked by g4 pawn. So Nf5#. Knight from b7 to f5: b7→d6/c5/f8... Let's find a 3-move path: b7-c5, c5-e4, e4-f6? f6 not f5. b7-d6, d6-e4? no, d6→e4 is knight? d6 to e4: yes that's a knight move. e4→f6/f2/g5/g3... e4 attacks f6, g5, g3... f5? e4 to f5 no. Hmm f5 reachable from: d4, d6, e3, e7, g3, g7, h4, h6. So Nf5 needs knight on d6, e7, g7, h6, d4, e3, g3, h4 prior. From b7: b7-d6 (1), d6-f5 (2)! d6 to f5: knight move? d6→f5: yes (2 files, 1 rank). So N d6 then Nf5# — mate in 2 moves: 35. Nd6, 35... c3 (forced), 36. Nf5#. Wait, but after 35. Nd6, Black plays c3. Then 36. Nf5 checkmate. Verify Nf5 is checkmate: covered above. Also does Nd6 allow anything? Black king still can't move, g5 pawn stuck. Black's only move c3. Good. Also check 35. Nd6: does it give Black king escape? King h4: g3 rook (defended by f2), h3 pawn (defended), g4 pawn (defended), h5 (g4 pawn attacks h5). King immobile regardless. Good. So play Nd6. Quip.

I've spotted a forced mate: the knight hops to d6 and then lands on f5, where the king's every exit (h5 via my g-pawn, g3 via my f-pawn) is already bricked. First, the elevator ride continues:

Played Nd6

Nd6b7 → d6

Enjoy your strut — my knight just hit the '2' button: next stop, f5, where the walls will close in for good.

GLM 5.3 Flash High· move 35…

Position: Black king h4, pawn g5, pawn c4. White: Kc1, Rg3, Nd6, pawns g4, h3, a2, b2, c2, f2. Only legal move is c3. So play c3.

Played c3

c3c4 → c3

Only move on the menu, so I'll order it — a pawn still salutes the gallows with style.

GLM 5.3 High· move 36

The knight to f5 was promised and it's mate! Nf5#.

Played Nf5#

Nf5#d6 → f5

Told you the walls would close in — I always deliver on a promise, especially a checkmate.
