 | | perfidious: The opening salvo of 19.Rxh7+ Kxh7 20. Qxf6 is a quite familiar motif, but matters became far more difficult after the obvious defence 20....Qg7. |
|
Jun-04-23 | | Brenin: 19 Rxh7+ forces 19 ... Kxh7 20 Qxf6, with the threat of 21 Rh1+ Kg8 22 Rh8 mate, e.g. 20 ... Qg7 21 Ng5+ Kh8 (Kg8 22 Bc4+ d5 23 Rxd5) 23 Qf4 Rxe2 24 Rh1+ Kg8 25 Qc4+ d5 26 Qxe2, and White is a P ahead, with a much better position. |
|
Jun-04-23 | | King.Arthur.Brazil: For me, potd is "normal": 9. Rxh7+ Kxh7 20. Qxf6 Rxe2 21. Rh1+ Kg8 22. Rh8#. I guess many will reach the same quickly. |

Jun-04-23 | | mel gibson: I saw that straight away.
White gets a pawn and a Knight straight back and then has a King hunt underway.
The Black King is too exposed behind an isolated pawn and many pieces can attack him.Stockfish 15 says:

Jun-04-23 | | jrredfield: I saw 19 Rxh7+ quickly enough but wasn't sure what should follow after 19 ... Kxh7 (19 ... Nxh7 is illegal) 20 Qxf6. Maybe 20 ... Kg8 21 Rxd6. Still not bad for a Sunday. |

Anyone know where one might get a decent price on a slightly used brain? |

 | | scormus: First two moves 19 Rxh7+ Kxh7 20 Qxf6 were easy to find, but then what does B do, and W after that? I thought if 20 ... Kg8, then 21 Rxd6. But after 20 ... Qg7 21 Ng5+, I expected 21 ... Kg8. After the text, ... Kh8, I wasn't sure, perhaps 22 Rh1+ or maybe Qh4+. When I saw 22 Qf4, allowing... Rxe2, it all became a bit of a mystery to me, and I gave up trying to guess the moves. |
|
Jun-04-23 | | agb2002: Black threatens Rxe2.
The white queen pins the knight. This suggests 19.Rxh7+ Kxh7 20.Qxf6: A) 20... Qg7 21.Ng5+
A.1) 21... Kh6 22.Rh1#.
A.2) 21... Kg8 22.Qf4
A.2.a) 22... Rxe2 23.Qc4+ d5 24.Qxe2 wins a pawn at least. A.2.b) 22... Rf8 23.Bc4+ d5 24.Rxd5 Bxd5 (24... Rxf4 25.Rd8#) 25.Bxd5+ Rf7 (25... Kh8 26.Qh4+ and mate next) 26.Bxf7+ wins. A.2.c) 22... Re4 23.Bc4+ Rxc4 (23... d5 24.Qxe4 dxc4 25.Qxc4+ Kf8 26.Ne6+ wins) 24.Qxc4+ d5 25.Qe2 (25.Qxc5 Rc8) wins a pawn at least. A.2.d) 22... Rad8 23.Bg4 looks good for White. For example, 23... Bc8 24.Bxc8 Rxd8 25.Qc4+ Kf8 26.Ne6+ Rxe6 27.Qxe6+ and 28.Qxc8. A.3) 21... Kh8 22.Rh1+ Kg8 23.Qf4, with several threats Rh7, Qxd6, Bg4, looks similar to A.2. B) 20... Kg8 21.Rxd6
B.1) 21... Qg7 21.Bc4+ Kh7 22.Qxg7+ Kxg7 23.Rd7+ wins decisive material. B.2) 21... Qf7 22.Qxf7+ Kxf7 23.Bc4+ Ke7 (23... Kf8 24.Rf6+ Ke(g)7 25.Rf7+ and 26.Rxb7 wins decisive material; 23... Kg7 24.Rd7+) 24.Rxg6 gets three pawns for the exchange, unclear. |

Jun-04-23 | | agb2002: I missed the far stronger 22.Qg5 in my line B.2. |

|
Jun-04-23 | | stacase: 23.Rh1+..Kg8 Missed this. I thought "Oh no you abandoned support at g5!" 24.Qc4+..d5 Ouch!
25.Qxe2 Oh that was great!
Maybe over the board I would have seen that Rook snatching beauty. |

Jun-04-23 | | vajeer: I considered the following lines:
22. Rh1+ Kg8 23. Qf4 Qf8 24. Bc4+ d5 25. Qh4 Qf6 26. Bd3 Re7 27. Bxg6 Rd8 28. Qh6 Rd6 29. Bh7+ Kh8 30. Nf7+ Rxf7 31. Bg6+ Kg8 32. Bxf7+ Kxf7 33. Qxf6+ Rxf6 34. Rh7+ Ke6 35. Rxb7 with a won endgame21...Kg8 22. Bc4+ d5 23. Rxd5 Bxd5 24. Bxd5+ Kh8 25. Nf7+ Kg8 26. Qd6 Re1+ 27. Kc2 Re2+ 28. Kd1 Qd4+ 29. Kxe2 Kg7 +-
21...Kg8 22. Bc4+ d5 23. Rxd5 Bxd5 24. Bxd5+ Kh8 25. Nf7+ Kh7 26. Qh4+ Kg8 27. Ng5+ Re6 28. Bxe6+ Kf8 29. Qf4+ Ke8 +- 21...Kg8 22. Bc4+ d5 23. Rxd5 Bxd5 24. Bxd5+ Kh8 25. Nf7+ Kh7 26. Qh4+ Kg8 27. Ng5+ Kf8 28. Qf4+ Ke7 29. Qc7+ Kf6 30. Nh7+ Qxh7 31. Qxh7 +- |
|
Jun-04-23 | | vajeer: In the first line below, 24. Bc4+ is important because it forces 24...d5 and closed the diagonal and takes black's bishop out of the rest of the game. |

 | | Honza Cervenka: I saw 19.Rxh7+ instantly, and quite quickly I have found a line 19...Kxh7 20.Qxf6 Qg7 21.Ng5+ Kg8 22.Bc4+ d5 23.Rxd5! Qxf6 24.Rd7+ Re6 (forced) 25.Bxe6+ Qxe6 26.Nxe6 +- or 23...Bxd5 24.Bxd5+ Kh8 25.Nf7+ Kg8 (25...Kh7? 26.Qh4+ Kg8 27.Ng5+ Kf8 28.Nh7+ +-) 26.Qd6 Re1+ 27.Kc2 Re2+ 28.Kd3 with decisive advantage but I did not consider 21...Kh8 at all. |

 | | Breunor: I'm a little surprised this is a 4 star puzzle - the first three moves seem pretty obvious. although without seeing more, it may be hard to play in a real game. |

White's bishop is en prise and 22 Bc4 is disastrous because the queen can take with check. <agb2002> for one suggests 22 Qg5! below, with the threat of 23 Rxg6+.  click for larger viewBlack has 22...Be4 for example as a defense. Looks difficult from here on. |

Jun-04-23 | | agb2002: <Jim ...
