I must admit after replaying most of the game, that already 39.Bc6 with the
later closing with d5 White opens Black the possibility for that late sacrifice.
The B simply is out of play. All such questions are trivial for super GM.
Therefore I was quite surprised how Kramnik played in Bahrain. For a super GM it
is possible to hurry over some thirty moves if the basic structure doesnt change
much. Rybka seems to see that the N has the option to attack Pe4 by Nc8-d6 so
that White has not much to do other than wait for the final stroke. Bc6 can only
walk to a8 or b7. In other words in such a position with all Black's P on black
squares the bN is better than the wB. But again why either Kasparov or Kramnik
never played such a trivial game against Fritz? Because that was advertising and
not a serious match. If such strategies could be confirmed by more examples I
would finally conclude that Rybka really has made some very significant steps
towards mastership in chess. However I dont believe in the myst that soon Rybka
will have no longer deeper or more important "holes" in its knowledge. The
problem is still that chess remains a game of utmost concretness and if you
wanted to program all the exceptions your code would look pretty fat.
