  takebackok: Think and think again Tuesday, easy start 22. Qh4 f5 23. Qxd8+ Nf8 24. Qe8 (threat Qf7) Qc7 up an exchange and a pawn still attacking now get the knight and other rook into the fight end in sight.

22. Qh4

(22. Qh4 (1.Qh4 f5 2.Qxd8+ Nf8 3.Qh4+ Kg8 4.Nd4 Qd6 5.Nxc6 Bd7 6.Qg5 Qxg3 7.Ne7+ Kf7 8.Qxg3 Re8 9.Be2 Rxe7 10.Bh5+ Kg8 11.Qh4 Rf7 12.Bxf7+ Kxf7 13.Qd8 Bf6 14.Qc7 a5) +7.06/46 644)

score for White +7.06 depth 46.

Jun-10-25  Mayankk: I thought 22 Bxh7 Kxh7 23 Qh4+ Bh6 24 Qxd8 wins as well.

22 Kxh7 is of course not forced. But anything else can't be much better, right?

Jun-10-25  cocker: Simples.
Jun-10-25  TheaN: No-sac double attack? That's new. Of course <22.Qh4> is a bit more involved than it looks at first glance, as it seems like we're eyeing on Bh7 (with mate) and Rd8, and because White can win a tempo with Bxh7+ it leads to mate, but that's a bit too eager.

<22....f5 (Kg8? 23.Bxh7+ Kh8 24.Bf5+ Kg8 25.Qxd8#)> protects h7 and gives the king some escape squares. <23.Qxd8+ +-> however, when the dust settles White goes from a piece for pawn down to an exchange and pawn up; because the attack's still ongoing this is practically the end: there's no clear-cut end after Black interposes on f8.

<Mayankk: I thought 22 Bxh7 Kxh7 23 Qh4+ Bh6 24 Qxd8 wins as well.

22 Kxh7 is of course not forced. But anything else can't be much better, right?>

White's already a piece down (the ♗:♙ exchange on the previous move), so just taking on h7 is in itself not enough. It is significantly inferior to 22.Qh4 after 22.Bxh7 Qf6 where Black can sort of hold on with a pawn down; position was already severely in White's favor of course so that didn't change much. +3 so winning, but 22.Qh4 f5 23.Qxd8+ is +7.

Jun-10-25  TheaN: Hm was this supposed to be 21.? That makes a bit more sense from a puzzle POV.

Jun-10-25  Andrew Chapman: I thought Rc1 was odd. I was expecting Re1.
Jun-10-25  Walter Glattke: Mayankk: 23.Bxh7 is nö check as in the "Classic Bishop Sacrifice" of the books, so 23.-Bd7 24.Rh3 Rac8 25.Bd3+ Kg8 26.Rh7 c5 no attack, wins knight instead rook
Jun-10-25  Mayankk: Thanks guys for the feedback.

Yes of course 22 Bxh7 is nowhere as strong as 22 Qh4. I was just curious if it still wins as the position after 22 Bxh7 Qf6 23 Rh3 Bd7 24 Bd3+ looks abysmal for Black even if there are no tactical fireworks available for White. Same goes for 22 Bxh7 Bd7 23 Rh3 Rac8 25 Bd3+ etc.

So yeah, +3 seems about right.
