Deep Rybka 4 not doing so well

[ernest]

Yes large pages are on. It took awhile to figure out how to do it but I did.

Can you share how to do it (in Windows)?

I will try some 30+5 games next.

Strangely enough, on my machine, Rybka 4.0 is crushing everything. However, I test at longer time controls, thus allowing me to absorb the games in progress.

My first impression of Rybka 4.0 is that it is a real predator, it really understands pawns breaks, and gains advantages by detonating the super quiet positions it this way. It attacks somewhat like Junior now (wow!), nothing like Rybka 3.0. Really a new engine for sure. Vas must have clipped the "Fruit" wings.
