13.exf6 is much better. |

hardly an insane puzzle - LOL
Stockfish 14.1 agrees with the first ply:
(17. .. Rxf4

And of course White can't take the Rook

| Apr-03-22 | | Brenin: The firat two moves 17 ... Rxf4 18 gxf4 Bh3+ 19 Ke2 were fairly easy to see. Then I wanted to play 19 ... Qb5+ 20 Kf2 Nd3+ and 21 ... Qxd5. |

 | | al wazir: After 25. Rxc5 Rxd1 26. Rxd1 Bxc5+, white has ♖ vs. ♗ + ♗, which is better than losing his ♕. |

 | | An Englishman: Good Evening: Saw the first three moves and knew Black had White by the nose. Gleizerov probably saw everything; this would have constituted another speculative sacrifice for me. 4/6 with one puzzle already known. Feeling content. |

| Apr-03-22 | | agb2002: Black is one knight down.
White threatens Nxe5.
The knight on f4 protects the light squares around the white king. This suggests 17... Rxf4: A) 18.Bxf4 Bh6+ 19.Ke2 Qb5+
A.1) 20.Kf2 Ng4+ 21.Kg1 Qc5+ 22.Qd4 (22.Nd4 Qxd5 23.Qe2 Qxd4+ 24.Be3 Nxe3 25.Qf2 Rf8 wins) 22... Qc2 (threatens Qf2# and Bc5) 23.Be3 Nxe3 24.Qxb4 Nxd5 wins. A.2) 20.Ke3 Ng4+ 21.Kd4 (21.Ke4 Nf2+ and 22... Nxd1 wins) 21... Qc5+ and 22... Nf2+, etc. A.3) 20.Bc4 Qxc4+ 21.Kf2 (21.Ke3 Ng4#) 21... Ng4+ 22.Kg1 Bc5+ and mate in three. B) 18.gxf4 Bh6+ 19.Ke2 Ng4
B.1) 20.Rf1 Bxf1+ 21.Qxf1 (21.Kxf1 Qf2#) 21... Qb5+ and Qxf1 wins decisive material. B.2) 20.Kd3 Nf2+ wins decisive material.
B.3) 20.Qd3 Re8+
B.3.a) 21.Ne5 Qf2+ 22.Kd1 Nxe5, with the double threat Nxd3 and Bg4+, is winning. B.3.b) 21.Be4 Qf2+ 22.Kd1 Qg2 must be winning (23.Nd2 Nf2+ 24.Kc2 Nxe4). B.3.c) 21.Kd1 Nf2+ wins decisive material. |

| Apr-03-22 | | Brenin: We've all been assuming that White has to take the R after 17 ... Rxf4, in most cases by 18 gxf4, though 18 Bxf4 {thanks <agb2002>!) is also possible. However, what if he simply plays 18 Kg2 ? Material is now equal. Black's position looks better, but is he winning? |
|
| Apr-03-22 | | yrotciv: I feel 25. Rxc5 Rxd1 26. Rxd1 Bxc5+ offers white some fighting chance (1 rook vs 2 bishop's in pawn endgame) |
|
| Apr-03-22 | | AlicesKnight: Found the first moves in; did not get as far as the pretty finishing point. White King feeling the draft ... |

 | | scormus: <Brenin .... 18 Kg2> I think it's part of the chess puzzle culture, to look first (and only?) at the defender accepting the offered material. In my case, once I decide the first move in OTB mode, I "play" it, see what the text is, and if it's what I supposed, play the next move.
Refusing it by 18 Kg2 would effectively admit an inferior position, though not necessarily lost. Today my moves followed the text until 20, when I chose .... Re8+ instead of .... Qc5. I thought B must have had it all figured out and that I'd overlooked something, but I see SF rates them about the same, at ca. +7 to B. To me the R check looks the natural continuation. I also didn't "find" 24 .... Rxd4?!, preferring .... Qe7. Again, I thought at the time I must have missed something. As it happened, W hastened the end with 25 Qxd4. What makes the weekend puzzles such a challenge is that often there are inaccuracies by both players. You think you've worked out the line and then the actual play deviates, you don't know who (if either) is right, and you have to regroup your thoughts. |

| Apr-03-22 | | VincitQuiSeVincit: In the 25. Rxc5 Rxd1 continuation, instead of 26. Rxd1 it's probably better for white to play 26. Rc8+ Bxc8 27. Rxd1 |
