But I have played _many_ games against the machines (mine >and others) and I must say "I don't get it" myself... Maybe you misunderstood. The apparent best line is not 16.Bxh7+, but rather 16.g3 Qh2 17.Bxh7+... so yes, g3 appears better than what GK played, but only by a small margin. Crafty doesn't see that 16...Nh2+ is perhaps weaker than Qh2. Will
