This keeps coming up, so I may as well add my two cents worth one more time.. You did _not_ reproduce the results of others. But then you didn't run the same test either. You used one computer, presumably with ponder=off. That is _not_ a reasonable test. Lots of reasons, but to make it simple: Let's play a match with no opening book. That favors the program with the lousy book. Let's play a match with search extensions and tricks disabled. That favors the program with the best eval. Let's play a match with evals disabled. That favors the program with the best search. Lets play a match searching to fixed depth. That favors the program that does the most work per node. Let's play a match searching to a fixed time limit. That favors the program that has a horrible automatic time allocation algorithm. In short, when you turn off _anything_ you most likely affect one program more than the other. You turned off pondering. I have reported several times that such hurts crafty, definitely. I allocate time based on the _assumption_ that I will save some time later in the game with correct pondering predictions. I don't when I can't ponder. The results are interesting, but they have _nothing_ to do with the way I would actually play a game against fritz in a real tournament. I would _not_ play without pondering enabled...
