Hence the reason it didn't play the so Called Better Move that >you found with you're PC. If it is the case than the logfile should tell use that Deeper blue changed it's mind so we can compare the moves of chess programs with the moves of deeper blue at least in cases that deeper blue did not change it's mind. I also do not see why do you think that we should use the same number of nodes. Deeper blue did not use null move pruning and I believe the algorithm of the chess programs of today is superior(every top program that I know except Junior is using null move and even Rebel started to use null move pruning). Junior also has other pruning rules. I do not believe that the deeper blue team were right in not using null move when all the programmers of today are wrong. Uri
