You says: Rybka with 50 minutes per game is suposed to be better than Naum with 60 minutes per game. Wrong. It is clear that my final figures prove the opposite. (In my Quad 6700, Fritz 11 GUI at 60 minutes game).
In a previous post you said: I have listen that Perfect15 is the best book available. This was the opinion also of other proficient poster such as Graham. Perfect15 is, also in my opinion, an excellent book. Rybka3 with Perfect15 is not able to win Naum4 with Storm. Now you said: "The only thing that your test prove is that probably Storm is a better book than Perfect15." (???).
Finally I amb testing again Naum4 and Rybka. Storm book was the winner in the serious Sedat's Books Tournament. Perfect15 did not compete there. In the fourth place there was an unknown -at least for me- book: Magnificient. In order to confirm that Naum4 does not benefit of the best book I am testing it with Magnificient, whereas Rybka3 has Perfect15. The advantage of Naum is huge. Tomorrow I will be post the final results.
Uri, I suggest you to chose a book for Rybka3. I will chose for Naum4 any other of the mentioned ones. I will test again both programs:
Quad 6700
Gui Fritz11
Ponder: Off
Books: The one you chose for Rybka3 and the one I choose for Naum4.
Game in 60 minutes.
I will be delighted to let you know the results.
By the way, the constructive disagreement, like yours, is always welcome from my side.

Regards from Barcelona.
