I have never seen a bug of any sort due to a hash table collision, but I store 32-bits in the table and use some more bits to index the table. I expect that if you are having transposition table bugs, that a more likely source of bugs are simple code defects. Make sure that the hash keys you're dealing with actually correspond to reality, and make sure that you didn't put your brain on backwards when you wrote the part that cuts off based upon hash table entries. Another suggestion is to seed your random number generator with a fixed value so you don't get different random numbers each time you run the program. You want repeatable behavior, for sure. bruce
