I've just finished this game here on RHP.
Nothing very interesting going on in the actual game: white won with a typical Bxh7 sacrifice. However, during my analysis I couldn't find any way to secure a decisive advantage against 12 ...Kg6.
13. h4 fails against 13 ... Rh8, I think. And, after 13. Qg4, I couldn't think of a good response against 13 ... f5. After 14. Qg3 f4, white seems to be in big trouble.
Was the sacrifice incorrect, after all, or is there anything I'm missing?

"I think it works in your game as well:"
It does seem to work, but beware of the knight fork at the end.
I only started analysis AFTER Bxf4.
The notes are a move out of order, and I can't seem to fix them.
Redit ... I just modified the notes. I guess if you can't move the notes, you can reword them.

Is that really winning for white? i don't see a lot going on after ... Bxe6.
If the game had continued like that, I would probBly have played Nxf4, forcing the exchange sac by black and getting a rook and a few pawns for two pieces. Probably winning for white, but not quite what you'd expect after playing Bxh7 in such favourable conditions.

Originally posted by danilopTruthfully, it's a complicated mess. The bishop sacrifice is sound a lot of the time, but Kg6 lines are always a slight bit confusing. Whenever, I play the sac, I have a sigh of relief when the king does return to g8. The fact of the matter is that it's a lot more complicated than it appears to be. Knowing the h4-h5 trick and the Qg4 move will help a huge percent of the time (also the Nxe6, winning the queen follow up to Qg4), but sometimes it just comes down to cold hard calculation. I have been looking at the computer's Qxg7 ever since I stopped editing my post. It seems as though the king is extremely bottled up and about to be mated. Every variation that I have been looking at seems to end very badly for black. For example, I will give the conclusion to your Bxe6 move ...

Obviously, this is only one path, but black is in a forced mate after Bxe6!!
The king is in a pickle like this in a lot of lines that I have looked at.
