When Kasparov chose Bxh7, he took a long time. Crafty was analyzing the
game live on ICC and turned in this 16 ply search result:
16-> 33:34 1.59 16. g3 Nh2+ 17. Kf2 Ng4+ 18. Ke1 Qh3
19. Rg1 Nd7 20. Kd1 Nf2+ 21. Kc1 Nb6
22. Re1 Nxd3+ 23. Qxd3 Bf5 24. Ng1
Qg4 25. e4 Bxe4 26. Nxe4 dxe4 27. Rxe4
Rxe4 28. Qxe4 Qxg3
After the Bxh7 move, I instantly got this:
10-> 2.86 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
11 4.41 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
11-> 5.46 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3 (s=2)
12 9.92 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
12-> 15.30 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3 (s=2)
13 29.72 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
13-> 39.29 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3 (s=2)
14 1:09 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
14-> 1:39 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3 (s=2)
15 2:47 0.00 16. ... Kh8 17. Ng3 Nh2+ 18. Kf2 Ng4+
19. Kf3
I would have preferred to see the g3 line myself... It looked (to me anyway)
that white had a lot of life left there and was a piece up... The attack might
have looked scarey, but it really didn't appear to be so to the computer...
I think he is simply not up to playing more games vs the computer. If I were
to venture a really outlandish opinion, rather than saying "DJ is maybe as
strong as DB" I now might say "DB might really be as weak as DJ". It appears
that Kasparov just doesn't have what it takes to play a 6 game match vs the
machines... Not having been there playing for a million bucks, I can't claim
to understand this. But I have played _many_ games against the machines (mine
and others) and I must say "I don't get it" myself...
