Subject: another test position---shredder5 cant see

Author: K. Burcham

shredder5 has a difficult time with the bishop sac. 19.Bxh7 has shown to be a
better move. but karpov decides to play 19.Ng5. so at least shredder will
play karpov's GM move. at this time karpov was rated 2725.
GM Knaak comment below.
i have one program that plays 19.Bxh7 in four minutes.
as you can see shredder5 does not see it at all in the analysis below.

"Missing the chance of a bishop sacrifice on h7. That would have certainly been
the better option if Karpov had wanted to play for a win. Of course proving this
with the help of a computer is much easier than finding it at the board.
[19.Bxh7+! is certainly more promising." comment by GM Rainer Knaak.
