I had them on HD. However, the problem seems to be that MChess slows down a lot during heavy TB access (8 Knps or less on P6-233, about 14 Knps on PII-400) which seems to outweigh the positive information from the TB's. Crafty is not affected this much since it's 3-4 times faster than MChess. >Maybe it is worse for MChess because it extends much more aggressively, thus >going deeper in selected lines than others and hitting on the TBs more often. Exactly. Crafty hardly ever goes below 1/2 its usual speed, MChess often goes to 1/10. --- Shep
