 | | al wazir: I don't understand the purpose of 21...Qc8. What does it accomplish? Surely 21...Ng4 is a better defense. If 22. Bxg4, then 22...Bxg5. |
|
Jul-06-22 | | Brenin: Black is ahead by R+P. Neither of the obvious captures on f6 gets anywhere, so it has to be the quiet move 21 Qh6, cutting off the Black K from f8 after 22 Nxf6+ and 23 Bxh7+. There is nothing Black can do to stop the eventual mate, e.g. 21 ... Bf8 22 Nxf6+ and 23 Qxh7 mate, or 21 ... Qd6 22 Nxf6+ Bxf6 23 Bxh7+ Kh8 24 Bg6+ Kg8 25 Qh7+ Kf8 26 Qxf7 mate. (The mate after. 22 ... Qxf6 is similar, but with 26 Bh6+.) |
|
Jul-06-22 | | Brenin: <al wazir>: 21 Qh6 Ng4 22 Qxh7+ Kf8 23 Qh8 mate. Black's 21 ... Qc8 accomplishes nothing because there is nothing he can accomplish. He can resign at this point. |

 | | ChessHigherCat: Monday follows Tuesday, like Merlin living backwards in "The Once and Future King": 21. NxN+ BxN 22. Qxh7+ Kf8 23. Bh6+ Bg7 24. Qxg7#. Well, on second thought, it's all forced but maybe it's a Tuesday by virtue of the number of moves. |

 | | ChessHigherCat: Ach hach, I forgot about the potential escape square e7! So it was really more of a Wednesday. Guess I'll only give myself 0.9999% of a point. Just kidding, zero. |

 | | agb2002: White is one rook, one knight and one pawn down. Black threatens dxe4.
White can eliminate the best defender with the knight or the dark square bishop so it is possible to play 21.Qh6, to control the escape spot f8: A) 21... dxe4 22.Bxf6 Bxf6 (22... Bf8 23.Qxh7#) 23.Bxh7+ Kh8 24.Bg6+ Kg8 25.Qh7+ Kf8 26.Qxf7#. B) 21... Nxe4 22.Qxh7+ Kf8 23.Qh8#.
C) 21... Bf8 22.Nxf6+ and mate next.
D) 21... Qc7 22.Nxf6+ Bxf6 23.Bxh7+ Kh8 24.Bxf6#. E) 21... Bc8 22.Nxf6+ Bxf6 23.Bxh7+ as in A. |
|
Jul-06-22 | | Granny O Doul: 22. Bxf6 looks faster. I think I'll ask Larry Evans. |
|
Jul-06-22 | | saturn2: 21.Qh6 and black has no defence against the continuation Nxf6 and then Bxh7 |
|
Jul-06-22 | | TheaN: <Brenin> explains the point and <saturn2> the followup of this puzzle in a very practical way. Qh6 cuts off f8 as defense whilst keeping the tension, among other things keeping e7 blocked, and threatening Nxf6+ with Bxh7+, followed by the typical light square mating pattern (Bg6+, Qh7+, Qxf7#). <21.Qh6! #6>, Black's potentially best try is <21....Ng4> to create counter chances, but <22.Qxh7+ Kf8 23.Qh8#> now f8 is not a problem as e7 is still blocked. The other move that attacks the queen 21....Bf8 22.Nxf6+ with 23.Qxh7# as now f8 is blocked. The longest prolonged mate forces Black to defend f6 directly with the queen on b6 or d6, of which Qb6 is the logical move. But after 21....Qb6, Black doesn't actually prevent the light square mating pattern: 22.Nxf6+ Qxf6 (Kh8 23.Qxh7#; Bxf6 23.Bxh7+ #3) 23.Bxf6 Bxf6 (Bf8 24.Qxh7#; else Qg7#) 24.Bxh7+ Kh8 25.Bg6+ Kg8 26.Qh7+ Kf8 27.Qxf7#, and we got to finish the pattern anyway. |
|
Jul-06-22 | | Cellist: I gave it only a few moments and missed it (so embarrassing!).
The neat thing (for Black) is that the wrong "solution" 21.Nxf6+ followed by 21... Bxf6 opens up the e-file with a potential Re1 mate. |

Jul-06-22 | | Hercdon: Elegant finish |
|
Jul-06-22 | | Hercdon: Although 20. � h5 would have given Black a winning position. Instead NxR gets Black mated |
|
Jul-06-22 | | Brenin: <Hercdon>: Well spotted! After 20 ... h5 the key move 21 Qh6 is impossible, and the captures on f6 lead nowhere. White is going to lose the B on g5 or the exchange on d1. |

Jul-06-22 | | King.Arthur.Brazil: Sorry, the King (me, fellows) didn't find the answer which is simple 21.♕h6 and game over. When you see the line 21...dxe4 22. ♗xf6 ♗xf6 23. ♗xh7+ ♔h8 24. ♗g6+ ♔g8 25. ♕h7+ ♔f8 26. ♕xf7#. That's why Black desperately sacrificed with 21...♕c8. Even with the line: 20...dxe4 21. ♖xd8 ♖axd8 22. ♕h6 ♖d6 23. ♗xf6 ♖xf6 24. ♗xh7+ ♔h8 25. ♗g6+ ♔g8 26. ♕h7+ ♔f8 27. ♕h8# Black wouldn't escape. Too sleepy today. |
