What is the reason that Deep Fritz is winning against Shredder in 2 hours per
move

See http://www.icdchess.com/forums/1/message.shtml?162134

It cannot be book learning because the programs did not play at this time
control before and outsearching is part of the game.

I believe that stefan is very good in opening preperation because Deep Fritz
never wins shredder when stefan is the operator when Fritz can win Shredder when
stefan is not involved(This is not only Deep Fritz against Shredder5 and Fritz6
won against shredder4 also in your last tournament and in the israeli league).
