I do not believe it. I believe that Deep Fritz is better than Deep Shredder in all time controls. Deep Fritz is winning Shredder5 at 2 hours per move. see http://www.icdchess.com/forums/1/message.shtml?162151 > >>Gambit2 is not more than 70 elo better than Gambit1 based on the claims on Rebel >>sites(I assume at most 50 elo from improving the engine and at most 20 elo from >>tablebases). >> >>It means that Gambit on the same hardware is at most 70 elo better than Deep >>Fritz. > >On tournament timecontrol i would say 100 Elo.See my argumentation before.

I believe that part of these moves are bad moves. I also think that Deep Fritz can find moves that Gamnittiger will not play even in 100 hours. I guess that Gambittiger2 is better than Deep Fritz but I do not guess that the difference is getting bigger when the time control is slower. Regards, Uri
