I can't say I am impressed with Deep Fritz play
Schredder5 clasic with some openings help on a slow system would have done much
better here.

Ans still the setupt h3 g4 f5 is of importance
Aslong if the program doesn't find this it's better not using e4 nextime it has
White or the match shall be extremely boring.
But I can't blaim Kramnik using it against Deep Fritz.
