There is something wrong with your hash-table. >Hash-hits in IsiChess are about 70-80%, exact hits ~25%. >Depth 30 with >3.00 score after 0.5 seconds on Athlon XP 2.6+. Thanks for the hashnumbers ... I calculated my hashhits wrong. I casted to an int ... and this made it go wrong because the hashhit counter is bigger as 32 bit. I cast it now to a double and I hit around 50% I will calculate the exact hits also. >I'll hope you don't fix this severe bug until saturday ;-) Yes I hope to fix it also :-)
