I store draws but not at the exact point that they occur. You can write something that will very carefully make sure that it doesn't ever store a 0.00 in the transposition table. I don't think this is necessary, and it doesn't do anything about cases where a draw score caused the value of a node to change score, without changing score to the draw value. But on the other hand, what possible good does it do to store a 0.00 when the reason you are storing that value is that you *just* detected a rep? When you encounter this node later, I suggest that it is better to be able to check for a rep again, and if there is one, return 0.00. If there isn't, then you avoided a mistake, because the value of the node is almost certainly *not* 0.00. Same with 50-move conditions. But yes, to go through and dissect out all of the 0.00's, that is a mistake I think. bruce
