Conditions: Jonny 256 mbytes hash Movei 64 mbytes hash(I suspect that more than it is counter productive for all time controls and even 64 mbytes is counterproductive for fast time control except very fast time control of 3 minutes per game or faster because in very fast time control movei does not waste time on clearing the hash because it assumes that it has no time for it and the old entries in the hash are still productive for better order of moves and movei does not suffer much from useless entries) Hardware A64 3000(2ghz) Movei-Jonny 36.5-13.5 at 1 minutes per game Movei-Jonny 34.5-15.5 at 2 minutes per game Movei-Jonny 33.5-16.5 at 3 minutes per game Movei-Jonny 27-23 at 4 minutes per game Movei-Jonny 23.5-26.5 at 10 minutes per game Movei-Jonny 2.5-3.5 at 20 minutes per game games played under winboard. It seems that Movei is simply weaker at long time control and it is not surprising because it has poor order of moves and bad use of hash tables. The surprise that I have so far is the good results of it in WBEC. Uri
