| Jul-13-17 | | Walter Glattke: To schachfuchs: f3 is the key, Qd2-Be3 to Bh6 and g4-h4-g5 to drive Nf6 away,
without Ne2 the attack is not possible.
Ne2 threatens later g4! |

 | | drollere: 20. Bxg7 was straightforward (clearing the h file); black can't capture the B as the threat is 21. Qh6+ and 22. Qh8#. it was necessary to work out that black's reply 20. .. Qxd2 would be met by 21. Bxf6, forcing the black Q to 21. .. Qxd1 (any retreat, or capturing the N, would give white 22. Rh8#). then, after Qxd1 22. Rxd1, black needs three moves to save the K, and white needs only two moves to mate. |

| Jul-13-17 | | RandomVisitor: I went for 20.Qc1 but I did not see all of the complications. I planned to deflect the black Queen, then Bxg7 followed by Qh6.

| Jul-13-17 | | Pedro Fernandez: LOL! 20. is obvious, but I didn't see the simple 20...Qxd2; okay just in seconds. After the latter one everything is obvious too. PS. Hey <Chris>, just thinking in puzzles? Why? |
|
| Jul-14-17 | | patzer2: <JTV> Thanks for the recommendation 18...fxg6! Although I'm not sure if it gives Black an even position, it does avoid losing with 18...hxg6?? 19. Bh6  (+2.93 @ 26 depth, Stockfish 8) and gives the second player fighting chances for a draw.Playing it out move-by-move with Stockfish 8 yields 18...fxg6 19.Ba7 Rc8 20.Qxb4 Rf7 21.Ng3 d4 22.Bb6 Qe8 23.Ba5 Bf8 24.Qd2 Nd7 25.Rc1 Bc6 26.Rc2 Bb5 27.Rxc8 Qxc8 28.Rc1 Qa8 29.Nh1 Rf6 30.Nf2 h5 31.Nd3 Rc6 32.Rxc6 Qxc6 33.Qc2 Qf6 34.Nac5 Nxc5 35.Nxc5 Bxc5 36.Qxc5 Bd3+ 37.Ka1 Qg5 38.Qc8+ Kh7 39.a4 Qxg2 40.Qc7+ Kh6 41.Ka2 Qc2 42.Qd8 Qb1+ 43.Ka3 Qa1+ 44.Kb4 Qxb2 45.Kc5 Bb1 46.Qh8+ Kg5 47.Qxe5+ Kh6 48.f4 Qc2+ 49.Kxd4 Qd3+ 50.Kc5 Qe3+ 51.Kd6 Kh7 52.Bc3 Qb6+ 53.Kd5 Qxb3+ 54.Kc5 Qa3+ 55.Kd4 Qxa4+ 56.Ke3 Qxe4+ 57.Qxe4 Bxe4 58.Kxe4 Kg8 = (0.08 @ 54 depth, Stockfish 8) (diagram below)

| Apr-08-20 | | Cheapo by the Dozen: Unless I'm overlooking something, after hardish Monday & Tuesday puzzles, we got a very easy Wednesday one. 21 Bxf6 seems to force mate that is immediate except for the short delay from Black's queen-sac Zwischenzug. |

 | | agb2002: White has a knight for the queen and a pawn.
Black threatens Qxd1+ and Kxg7.
White can force mate with 21.Bxf6 Qxd1+ 22.Rxd1 Red8 (22... exf3 23.Rh1 Be4+ 24.Kh1 g5 25.Rh8#) 23.Rh1 Rd1+ 24.Rxd1 Kf8 25.Rh1 Ke8 26.Nc5 and 27.Rh8#. |
|
| Apr-08-20 | | stacase: Much easier than yesterday.
Over the board I doubt that I would have passed up snagging the Black's Queen, but since it was a puzzle I could see that only one Rook was needed to sit on h8 to do the job. So Black's f6 Bishop had to go. |
|
| Apr-08-20 | | Walter Glattke: Mate can be stopped with sacs, 21.Bxf6 Qxd1+ 22.Rxd1 Rfd8 23.Rh1 Rd1+ 24.Rxd1 Kf8 25.Rh1 Ke8 26.Rh8+ Kd7 27.Rxa8 giant material advantage. Ah, yes, they had 26.Nc5, too, no escape then. Kh7 is also mate by Rh1. |
|
Apr-08-20
 | | FSR: 21.Bxf6!! (threatening Rh8#) Qxd1+ 22.Rxd1 followed by Rh1 and mate. |
|
| Apr-08-20 | | saturn2: 21. Bxf6 threatens mate in one. Black can delay this but this costs too much material
21...Qxd1+ 22. Rxd1 Rfd8 23. Rxd8+ 2 pieces more. |

|
| Apr-08-20 | | goodevans: <saturn2> Actually the best black can do is delay mate by a mere 4 moves. After <22...Rfd8> white should press on with <23.Rh1>. Now the only delaying tactic is <23...Rd1+ 24.Rxd1>. Now black can try to run his K to the Q-side but after <24...Kf8 25.Rh1 Ke8> white can shut the door with <26.Nc5> and it's mate next move. |
|
| Apr-08-20 | | Damenlaeuferbauer: After long pondering, my old Colombian and Svedish friend Pontus (but not Pilate, the crucifier!) finally found 21.Bxf6! and mate with Rh8 cannot be avoided, because the white bishop blocks black's f-pawn. I wish all true chess players out there a happy and blessed Easter! |

 | | Dionysius1: Well chosen, whoever does these puzzles. It took me longer than it should to accept that moving the bishop backwards was both calm and effective. A case of it staring me in the face with my eyes shut :-) |

| | OhioChessFan: The Bishop/Rook combo in the corner always reminds me of this game: Spielmann vs Tarrasch, 1912 |
|

 | | scormus: Perhaps what makes this puzzle fun is figuring out the number of moves to force mate, against the most persistent delaying tactics ;) What is the rule in the case 21 W to play with, say, 5 s left on the clock (and no increments)? |
|
| Apr-08-20 | | sakredkow: Easy peasy. I needed that! |
|
| Apr-08-20 | | Brenin: It's nice for the N on a4 that he can finally join in by shutting the door with Nc5, as <goodevans> pointed out. By contrast, the "better placed" N on e2 seems totally useless in this combination. |
