And here it might be indeed ram which is involved. (The available ram on your system is not always the same.)

I'm not sure what you mean by "random number of the >chessmaster book". --------------------------------------------------------------------------------- No many 25percentage moves of the Chessmaster book are known bad moves. And these acure frequently on the board. Ok after some games book learning will avoid it but then your already down many points.
