| Jan-10-20 | | goldfarbdj: Relatively easy for a Friday. The first move leaps right out at you. After that, there are a few different variations to calculate, but it's easy to see that they all result in mate or a lost queen on a1 (or both). |

 | | FSR: Presumably the solution begins with 30...Rxg2+! 31.Kxg2 Rg8+ and now (a) 32.Kh1 Qxa1 33.Rxa1 Nf2#; (b) 32.Kh3 Nf2+ 33.Rxf2 Qxa1; (c) 32.Kf3! Nd2+ 33.Kf2! (33.Ke2 Rg2+ wins the queen). But now? I'm not sure. |

| | FSR: Ah! I missed the murderous 35...Nc5+! |
|
| Jan-10-20 | | Cheapo by the Dozen: I missed the unplayability of 32 Kh1, so I whiffed completely. |
|
| Jan-10-20 | | talsterch: why is kh1 unplayable?? |
|
| Jan-10-20 | | SpamIAm: <talsterch>, because if 32.Kh1 black replies 32...Nf2+ winning the queen (and mating). |
|
| Jan-10-20 | | Walter Glattke: I see no escape from check chain, so 35.Kc2 Ndb3+ and queen lose. |

| Jan-10-20 | | malt: Got 32.Kf3
(32.Kh3 Nf2+ 33.R:f2 Q:a1 )
32...Nd2+ 33.Kf2
(33.Ke2 Rg2+ )
33...Nce4+ 34.Ke2
(34.Ke1 Q:a1+ 35.Ke2 Q:f1# )
34...Rg2+ 35.Kd3 Nc5+ 36.Kc2 Ndb3+ 37.Rf2 R:f2+ 38.Kb1/Kd1 Q:a1# |

| Jan-10-20 | | jith1207: I got the puzzle fully, a miracle of sorts.
I sacrificed the rook, but initially was insecure in getting rid of the Queen. After taking the Queen exchange, I tried the same sequence with Nd2+ but the King escapes without a threat along the diagonal where Queens were originally present, moreover exchanging Queens created mate-in-1 threat for the opponent!! So what does that tell you?
Try the same combination overall, without exchanging the queens, keeping the Black Queen hanging without any support. It's gonna be alright because both knights and rook create an intricate web of checks and mate threats, that the White King needs to end up in the back rank, allowing the Black Queen to make the final checkmate move by now support-less enemy queen! |

| Jan-10-20 | | 5hrsolver: 30...Rxg2+ 31. Kxg2 Rg8+ 32. Kh1 Nf2+ 33. Rxf2 Qxa1+ 34. Rf1 Qxf1# 30...Rxg2+ 31. Kxg2 Rg8+ 32. Kh3 Nf2+ 33. Rxf2 Qxa1 30...Rxg2+ 31. Kxg2 Rg8+ 32. Kf3 Nd2+ 33. Ke2 Rg2+ 34. Kd1 Qxa1+ 35. Kc2 Nxf1# Or as in the game. |

| Jan-10-20 | | agb2002: Black has a knight for a bishop.
White threatens Nxb8.
Black has five pieces to attack the white king. This leads to consider 30... Rxg2+ 31.Kxg2 Rg8+: A) 32.Kh1Nf2+ 33.Rxf2 Qxa1+ 34.Rf1 Qxf1#.
B) 32.Kh3 Nf2+ 33.Rxf2 Qxa1 wins decisive material. C) 32.Kf3 Nd2+
C.1) 33.Ke2 Rg2+ wins (34.Kd(e)1 Qxa1+ wins; 34.Rf2 Rxf2+ 35.Kxf2 Qxa1). C.2) 33.Kf2 Nce4+ wins the queen at least as above. |

| Jan-10-20 | | saturn2: Black could take the pawn b5 but there is something much better: 30...Rxg2+ 31. Kxg2 Rg8+ 32. Kf3 (king moves to h file lose quicker) Nd2+ a. 33. Ke2 Rg2+ now white loses the queen
b. 33. Kf2 Nce4+ 34. Ke1 same as a. |
|
| Jan-10-20 | | King.Arthur.Brazil: Dear <agb2002>, I followed your comment, however, I guess that on the line B) Black could play 32. <♔h3> ♘c3, because to avoid 33. ♕h6#, White will have to lose his ♕ and more. (e.g. 33. ♕xc3 ♕xc3
34. ♖f3 ♘e4 35. b6 ♘f2+ 36. ♔h4 ♕f6+ 37. ♔h5 ♕g6+ 38. ♔h4 ♕g4# or 34... ♘e4 35. ♖g3 ♘xg3 36. hxg3 ♕xe3 with check-mate near. |
|
| Jan-10-20 | | spazzky: <SpamIAm>because if 32.Kh1 black replies 32...Nf2+ winning the queen (and mating). 32. Kh1 Nf2 loses to Kxg2. There is mate in 6 if black plays Qxa1 however, forcing the white rook to give up the f2 square for the knight |

| Jan-10-20 | | Damenlaeuferbauer: After long pondering, my old Ukrainian friend Viktor, who is also a great expert of the French defense, finally found 30.-,Rxg2+! 31.Kxg2,Rg8+ 32.Kf3 (32.Kh1/Kh2,Nf2+) 32.-,Nd2+ 33.Kf2 (33.Ke2,Rg2+) 33.-,Nce4+ 34.Ke2,Rg2+ 35.Kd3,Nc5+ 36.Kc2,Ndb3+ -+. The immortal Vladimir Kramnik once wrote, that the Dutch Stonewall is one of few openings, that gave black more space in the center than white. Both are very good opening choices for black, and a lot of players have combined them in their repertoire. |

| Jan-10-20 | | morfishine: Very nice finish here |
|
| Jan-11-20 | | agb2002: Dear <King>, 32... Nc3 is winning according to Stockfish but White has 33.Qe1, holding a bit longer. |
