Aug-19-23  agb2002: All white pieces are ready to attack starting with 24.Nxf7 (24.Qf6 Qf5):

A) 24... Rcxf7 25.Qf6

A.1) 25... Qf5 26.Bxf7+ Kh7 (26... Rxf7 27.Re8+ and mate in two) 27.Bxg6+ wins decisive material (27... Qxg6 28.Qxf8; 27... Kg8 28.Qxf5 Rxf5 29.Bxf5).

A.2) 25... Kh7 26.Bxf7 Qf5 transposes to A.1.

A.3) 25... Qc7 26.Qxg6+ Kh8 27.Qh6+ (27.Re8 looks also winning) 27... Kg8 (27... Rh7 28.Qxf8#) 28.Rd6 is winning (28... Ne7 29.Rxe7 Qxe7 30.Rg6#).

B) 24... Rfxf7 25.Qf6 Qf8 26.Qg6+ Kh8 (26... Qg7 27.Re8#) 27.Bxf7 Rxf7 (27... Qxf7 28.Re8+ wins decisive material) 28.Rd5 Rh7 29.Re8 wins.

C) 24... Kg7 25.Qh6+ Kf6 26.Rd6+ and mate in two.

Aug-19-23  devere: Apart from 24 Nf7, 24.Re8 is also good enough to win. 24...Qxe8 25.Qxc7 Qe7 26.Qxe7 Nxe7 27.Rd7 and White wins a piece.

Stockfish 16 says mate in 25:

24. Nxf7

(24. Nxf7 (Ng5xf7 Rf8xf7 Qf4-f6 Qc8-f8 Qf6xg6+ Kg8-h8 Bb3xf7 Rc7xf7 Rd1-d5 Rf7-g7 Rd5xh5+ Kh8-g8 Qg6-e6+ Qf8-f7 Qe6-h3 Qf7xh5 Qh3xh5 Nc6-e7 Qh5-e8+ Kg8-h7 Re1xe7 Bb7-f3 Re7xg7+ Kh7xg7 g2xf3 a7-a6 Qe8-d7+ Kg7-f8 Qd7-c8+ Kf8-g7 Qc8xa6 Kg7-f6 Qa6xb6+ Kf6-e5 Qb6-a6 Ke5-d4 h2-h4 Kd4-d5 h4-h5 Kd5-e5 h5-h6 Ke5-d4 h6-h7 Kd4-c5 h7-h8Q Kc5-d5 Qa6-b6 Kd5-c4 Qh8-d4+) +M25/46 317)

White wins _ mate in 25.

Aug-19-23  Brenin: 24 Nxf7 R(either)xf7 25 Qf6 leaps out as the obvious line of attack, with Qxg6+ threatened, but 24 Ne4, threatening Nf6+ and Nxh5 also looks good for a win, if less crushing.

  An Englishman: Good Evening: 11/14 result in a bizarre week--solved all four of the weekend puzzles, flubbed one each from Tuesday, Wednesday, Thursday. Oh, well--could have gone worse.
