The question is if Ruffian played 19...e5 because of bad book or because of bad
engine.


I have also one note about the analysis
It seems that I gave Deep Fritz only 1 or 2 mbyte in the previous analysis to
depth 13(I am not sure)

Here is again Deep Fritz(P800)32 mbytes hash(more than twice faster)

It seems that deep Fritz did not read the theory that says that doubling the
hash tables is only 6-7% speed improvement because it is more than twice faster
that is clearly more than 1.07^5 faster(another possible explanation is that
deep Fritz was unlucky in this position).
