65. Qg7 Qc6 (Qg6l oses the quuen after g4+) 66. g4+ Kh4 67. Qe5 threatening Qg3 mate |
|
| Jun-10-20 | | NARC: I thought white would play 65. Qg7 |
|
| Jun-10-20 | | saturn2: In my line 65...Be2 is useless. White has 66 Qf8. |

|
| Jun-10-20 | | agb2002: The alignment of Black's royal family on the e8-h5 diagonal suggests 64.Bh5+ Kxh5 65.Qf5: A) 65... Qxe7 (or 65... Bd7) 66.g4+ Kh4 67.Qf2#. B) 65... Qb8 66.Qf7#.
C) 65... Be2 66.g4+ Bxg4 67.hxg4+ Kh4 68.Qf3 Qb8+ 69.Kg2 Qb2+ 70.Qf2+ Qxf2+ 71.Kxf2 c4 72.e8=Q wins. |

| Jun-10-20 | | jith1207: 65...Be2 66. g4+ Bxg4 67. hxg4+ Kh4 68. Qf8 is also good enough with 69. e8=Q |
|
| Jun-10-20 | | boringplayer: I went with 65.Qf6, which appears to win as well. |
|
| Jun-10-20 | | Ceri Evans: I would have played 64. h4 |
|
| Jun-10-20 | | AlicesKnight: Found 64.Bh5+ after a little thought; the only defence (65.... Be2) concedes the second queen and there is no perpetual. |
|
| Jun-10-20 | | Brenin: After a minute or two trying and failing to force the e-pawn through, I found 64 Bh5+ Kxh5, with several possible follow-ups (follows-up?): 65 Qe6 or Qf5 are best, preventing the Black B from defending the K, though others, such as Qf6, also work. Black had the better position for much of this game, only going wrong with 55 ... Qf8, when a more active response was needed.. |
|
| Jun-10-20 | | latebishop: Like Ceri Evans, I found that 64.h4 also wins, though much more slowly. I missed the elegant winning combination. |

| Jun-10-20 | | mel gibson: I saw the first move but the 2nd was harder.

 | | perfidious: Piquant finish: Black even manages to be rid of his auld enemy, the quicksilver pawn at e7, before facing the executioner, but it avails him naught. |
|
| Jun-10-20 | | Predrag3141: Another POTD on another day could start here.
click for larger view58 e7 (as played) and 58 Qb2+ are roughly equal ways to win. In both cases, Stockfish recommends Black giving up his bishop in exchange for the passed pawn. |

| Jun-10-20 | | TheaN: This Wednesday took me a while just because I wanted a clean finish. The cleanest finish is <64.Bh5+ Kxh5 (Kg7 65.Bxe8 mate soon) 65.Qf5 Be2 (else 66.g4+ Kh4 67.Qf2#)> unless Black drops the queen directly which leads to mate also <66.g4+ Bxg4 (Kh4 67.Qf2#) 67.hxg4+ Kh4>

Here I, and a few with me chose the practical solution 68.Qf3!? #16 Qb8+ (else Qh3#) 69.Kg2!. Somehow I missed Qb2+ but it doesn't make the situation different as there's no defender at e7 so 69....Qb2+ 70.Qf2+ Qxf2+ 71.Kxf2 Kxg4 72.e8Q #10. Even better is 68.Kg2! which preempts Qb8 as now 68....Qb8? 69.Qf7# still, and having only a8 and c6 available means the b2 check is not there. After 68....Qc6+ 69.Qf3 White queens faster as 69....Qxf3+ 70.Kxf3 with e8Q is forced. Even 68.Qf8 wins, though a bit slower. |

I quoted what was given after 68 Kg2 Qb8 to reinterpret it. What must be meant is not 69 Qf7# but 69 Qf2+ Kxg4 70 Qf3+ Kh4 71 Qh3# |

| Jun-10-20 | | Damenlaeuferbauer: After long pondering, the very strong Romanian chess player Mihai Suba, who missed the candidates in the Las Palmas interzonal 1982 by just 0.5 points and had G. Kasparov on the ropes with the black pieces in the 1986 olympiad, finally found the bishop sacrifice 64.Bh5+!,Kxh5 (otherwise black loses his queen) 65.Qf5! (the black king is encaged and nothing can prevent g4+ and Qf2#). Very beautiful indeed! |

| Jun-10-20 | | Predrag3141: <Everett> White wins the exchange for a pawn with 1 Bh6+ Kg6 2 Qe4+ Qxa3. Is there better? |
|
| Jun-10-20 | | Nullifidian: The alignment of the king and the queen along the same diagonal led me to: 64. ♗h5+ ♔xh5 65. ♕f5 Δ ♙g4+ and ♕f2#. The only move that prolongs the game for black is 65... ♗e2 66. ♙g4+ ♗xg4 67. ♙hxg4+ ♔h4 68. ♔g2 Δ ♕f2+ followed by ♕f3+ and ♕h3#. If black plays ♕a8+ or ♕c6+ in response, then blocking with 69. ♕f3 forces the exchange of queens and the e-pawn will promote. As an aside, there's a nice mate if instead of 65... ♗e2, black plays Qf8. Then the quickest way to mate is the underpromotion 66. ♙exf8=♘! with any move followed by either ♕g6# or ♕g4#. And even if you go through the bit with the bishop capturing the pawn, the underpromotion theme still works. After 68. ♔g2 ♕f8, it's 69. ♙exf8=♘ again and any move, of which there are only two, is met with ♘g6#. |

 | | gawain: I saw that the clever 64 Bh5+ forcing 64... Kxh5 must be the key--but did not appreciate how decisive was the quiet follow-up 65 Qf5. |

memberJun-10-20 Predrag3141: <Everett> White wins the exchange for a pawn with 1 Bh6+ Kg6 2 Qe4+ Qxa3. Is there better?>How about 1.Bh6+ Kg6 2.Bf4 preparing 3.Re5 |
|
| Jun-10-20 | | Predrag3141: <How about 1.Bh6+ Kg6 2.Bf4 preparing 3.Re5> Without the benefit of Stockfish, 1 Bh6+ Kg6 2 Bf4 Kg7 looked OK. But then 3 Re5 seems to win. Other defenses: 2 … h6 or 2 … Qf5. Related question: Can we get Stockfish to analyze positions other than those whose IDs we know in chessgames.com? When I try entering FEN notation in the laboratory page analysis takes unlimited time. |
|
| Jun-11-20 | | Everett: <Predrag> I’ve never used Stockfish I’m the fashion you are suggesting... would be cool tho if it could. Btw, the position i posted is from Seirawan vs Bisguier, 1975 White to play and win after Black Played 32..Rb7 I think your line is actually best, picking up the b7-R |
