I just finished a game Game 6058677 where I had a chance to use the classic Bxh7 sacrifice; from what I've read and from what I've learned through experience, the Bxh7 sacrifice is most likely to work when
A) A Knight can check on g5 and a Queen can get to h5 (these are the usual prerequisites for the sacrifice)
B) A bishop exists on the c1-h6 diagonal
c) A pawn is on e5 to prevent a Knight from defending at f6
d) If white is not castled, a pawn on h4 defending g5, which would unleash a discovered check on h7 with the rook if the g5 knight were captured.
Does anyone have any good games where Bxh7 worked, or perhaps even better, games where Bxh7 did not work? Or perhaps any more ideas what makes the sacrifice successful and what makes it fail?
