Black was almost fine in this line, except Rybka had 33.Nd7!! with a mate in 15 :P

I understand that you are joking but 33.Nd3 also gives clear advantage for white so it is hard to say that black was almost fine in this line.
Parent - - By Alkelele (***) Date 2007-03-06 22:12
It's ok :-) I meant fine compared to earlier black alternatives.
Parent - By Eduard (***) [de] Date 2007-03-06 22:25
In my opinion Rybka played his best 2 (from 3) Startpositions.

In my Opinion Rybka is Favorite without pawn h2, g2 and a2.
Ehlvest is Favorite when Rybka will play without pawn f2 and d2.
In the positions without pawn b2, c2 and e2 the game is open.
