There was only one position when maybe Deeper blue is better than Deep Fritzand I am not sure about it because it is nopt clear to me that Rec1 is the right move. If Deep fritz converges to Rec1 only after many hours then it is going to be the first evidence that may help me to change my mind and to believe that deeper blue is better than Deep Fritz on the best hardware of today. I prefer that other people do the analysis with Deep Fritz because my hardware is not the fastest but unfortunately people are not interested to try to prove that I am wrong so I am afraid that I will have to try to prove that my opinion about Deeper blue is wrong without help from other people.
