| Jan-12-19 | | jith1207: Move 24 would have been very obvious so 23 acts as a precursor, I guess. But yes, it is hard to get the theme for the puzzle in that position unless you see the same. |
|
| Jan-12-19 | | devere: <An Englishman: Good Evening: Can't deny the fiendish difficulty of this puzzle, but does it seem strange to anyone else that it begins on move 23?> No. 23.Bc1!! is a great move, a chess career highlight. It reminds me a little bit of Karpov's 24.Nb1!! against Spassky. Karpov vs Spassky, 1974 |

 | | NM JRousselle: The key move 23 Bc1!! is tough to find. I have often told students that the most difficult attacking moves to find are retreating moves along a diagonal. |
|
| Jan-12-19 | | NBZ: <NM JRousselle> Agreed, such a hard move to find, and yet it serves so many purposes: sets up the battery with Bc1-Qd2, and allows the bishop to position itself later on the a1-h8 diagonal. |
|
| Jan-12-19 | | Walter Glattke: 23.Bd4 Rf7 24.Be5 isn't it better!?
23.-Rg8! 24.Rxg8 Kxg8 25.Rg1+ Kf8 26.Bxc5+!? Qxc5 27.Qh8+ Ke7 /26.Bg7+ Kf7 /26.Rg7?? Rf1+ |
|
| Jan-12-19 | | Cheapo by the Dozen: I whiffed completely, and went with 23 Rd6 instead. The rook is poisoned, and that move looks to regain the pawn with threats. But after 23 ... b5, the threats evaporate (although the pawn recovery doesn't), and the engine sees the position as a dead draw. |
|
| Jan-12-19 | | schachfuchs: I guessed the main theme of this puzzle would be the exploitation of the opposite coloured bishop for attacking on the black squares (esp. h6). Nevertheless, I couldn't find the nice retreat Bc1, let alone the final screwer b3/Bb2. It's also worth mentioning that black had neither the chance to prevent the set up of the battery (i.e. Qd2 OR Qe3), nor to cover the square h6! |
|
| Jan-12-19 | | malt: Looked at 23.Rd6 b4 24.Qd2 Bd5 25.R:a6
did not see 23.Bc1. |
|
| Jan-12-19 | | ChessHigherCat: The only hard part was getting the first move: c1, you see them all. |
|
| Jan-12-19 | | TheaN: Oh boy. Nope. Really wanted Bf4 to work but the piece itself is probably the most crucial for the White attack in the end, so surrendering straight away ain't a good idea. <23.Bc1!!> holy bollocks what a move. We all know that opposite colored Bishop endgames have a tendency to draw, but many forget that they're the fuel of an unstoppable attack as Saric demonstrates here with precision. Black's helpless against both Qd2 and Qe3, and from there on out the attack plays itself. Mindblown. |
|
| Jan-12-19 | | get Reti: The puzzle tricks you, because you're so focused on the queen and rook coordinating on g7 that you don't think of taking two moves to shift the queen to a different diagonal. |
|
| Jan-12-19 | | EdC: Why not 25...c4 followed by ...c3? |
|
| Jan-12-19 | | saturn2: I went with 23. Bd4
23...Rg8 (how else reasonably defend g7?) 24. Rxg8 Kxg8 25. Rg1+ Kf8 26. Bxc5+ |
|
| Jan-12-19 | | Otoy: What a forceful attack! At the conclusion, the enemy queen was cut off by the rook from protecting the bishop shielding the king, which means instant mate. If the queen took the rook, the soon to be fianchettoed bishop will unleash the sharp guillotine.
Beautiful! |
|
| Jan-12-19 | | King Harvest: Like <schachfuchs> I puzzled out the theme but not the execution. Which makes for an enjoyable and educational fail. I don't think I'm ever going to find Rd7 five moves deep. It's hard enough to find on the move. But the puzzle reminds me of the kind of positional driven tactic Jeremy Silman teaches in ReAssess Your Chess, the idea of visualizing ideal positions and/or placement of pieces and figuring out how to get from here to there. The idea that the queen and bishop can be re-positioned to bring the mating net together could arise from that kind of thinking in my opinion. (It's also a kind of thinking one doesn't tend to need when solving a chess puzzle.) |

thank you for a very instructional post ( via Jeremy Silman ). I have never thought of visualizing ideal placements of pieces, or pawns for that matter !
May get hold of that book: ReAssess your chess |

 | | Jimfromprovidence: I tried 23 Bd4 as well but 23...Rd8!, below, is one move that stops 24 Rg7+.

| Jan-12-19 | | landshark: Completely beyond me - |
|
| Jan-12-19 | | FlashinthePan: Beautiful! And the final swischenzug queen diversion of 27.Rd7 comes as the icing on the cake. |

|
| Jan-12-19 | | agb2002: White is one pawn down.
The white queen and rook on g1 converge on g7 and the black queen is defenseless. These details suggest Bd4 and Rd4, however Black has b4. Another option is 23.Bc1 threatening Qe3 and Qd2. I'd probably play Bc1. |
|
| Jan-12-19 | | Cibator: Another game where this surprise retreat Bc1 is key to a White victory: Reshevsky vs C H Alexander, 1958 After Black's 23. ... Re5 (given a "!" by Reshevsky), this unexpected retreat seems to be the best (or even only) way of maintaining White's advantage. |
