Realized after I sent last message that these might help you out a little too: Hash probes: 357103 Hash stores: 159816 hit exact: 2084 store exact: 1166 hit upper: 13164 store upper: 52337 hit lower: 164747 store lower: 106313 hit unusable: 101410 store nulllw: 0 deep/fast: 257292 / 68267 (72.05% / 19.12%) Efficiency: 91.17% Probes is calls to HashLookup. Hit exact is exact hits with enough draft to use. Hit upper/lower is enough draft and usable with current A/B to cause a cutoff. Unusable is not enough draft (but still ordered first). Stores are exactly what you think. Store nulllw is lower bounds stored after a null move cutoff. The deep/fast numbers are for the two halves of the transposition table... one implements deeper-only replace and the other always replaces. These tables are the same size currently although I would be interested in anyone with experience shrinking the always replace table... The efficiency numbers include unusable hits (basically if I match a sig in the hash the numerator of the efficiency ratio increases. The denominator is the total probes). These numbers are from the output of that same 5 sec search I am following up to. Good luck! Scott
