> Was wondering if it's possible for you to include Komodo in your test.  It would be interesting to compare Komodo to other top engine's single core performance.

Actually your idea sounds good,but however i dont want to promise

I mean, in case of running many games (including more engine versions without pawn) under such handicaped conditions,
then i am afraid that all engine Elo standings will be effected

As we know,the engines without books perform quite differently than using neutral books

Lets see...maybe later i can make a duel-match only Rybka vs Komodo without pawn

Btw,its too early for announcing,but however i am shocked by the current Rybka's performance

Greetings,
Sedat

>I don't understand the question. You're going to handicap Rybka 4.1 by removing it's e-pawn and play random opponents?

Yes...Rybka 4.1 is playing without one pawn
I mean, e2 pawn is removed when Rybka is White
And when Rybka is Black,e7 pawn is removed too

As i mentioned before,Rybka's opponents are playing with all pieces

Best,
Sedat

For example,here are two games played under such handicapped conditions:
