I may be wrong (I don't use machines to analyze); but doesn't 22.Bxh7+ lead to a forced mate?
Jerry, how many moves deep are you seeing a mate? I see white winning material, but I don't believe white can mate for at least 10 moves or more!
Black is practically in zugzwang on move 46. What happens after 46...Rxd7? It looks drawish after 47.Bxd7 Kxd7 48.Rg8 Be7, unless I'm missing something.
22.Bxh7+ definitely looks called for but I couldn't see a forced mate. 22...Kxh7 23.Qh3+ Kg8 24.Rh4 and I think 24...Qb6+ is necessary so 25...f6 at least becomes possible. If 24...f6 25.Rxf6! gxf6 26.Rh8+ Kf7 27.Qh5+ Kg7 28.Qh7#. Nice sacrifice, Jerry!
Thanks for the interesting game, Joe!
I agree with your analysis Ernie!
Dialog!! Great! Thanks Joe!
After 24....Qb6+ (the only move that doesn't lead to a forced mate)
25.Kh1 f6 26.Rh8+ Kf7 27.Qh5+ g6 28.Qh7+ and blacks loses a lot of material in all variations. Like Joe said opposite colored Bishops favor the attacker in the Middlegame.
