It isn't xboard/winboard compatible or anything. Yes, I have to clear the hash table when analyzing on ICC. Crafty has some asymmetry, and if I don't clear the hash when I change sides, the scores and search would be unstable and uninterpretable as they would bounce around badly. > >crafty(C)(211): (Project/TheHate) d11-> 8273K/s 44.07 -1.81 32. ...
