Fowell (fowell@netcom.com) Richard, This is interesting, I'm glad you brought it up. My program has an odd bug, which is that it will give a mate score occasionally where no mate exists. It occurs in some of the test suite positions, and only after > 11 ply. I've tried it w/o hash tables, but it takes so long to get that deep without the hash that I don't know if the hash is the cause or not. I'll look into it further. Will
