There are positions that Deep Fritz can solve faster than Deeper blue
the position when Deeper blue missed a win by Kh1 in game 2 when it played Kf1

I already posted the analysis of Deep Fritz and here it is again in the end of
my post

It may be interesting to give Deep Fritz to analyze game 4 and game 5 from the
match when you give it some hours for every position.
I suspect that it may find that kasparov missed a win that deeper blue did not
see.
