Thanks to Brice Boissel, I was finally able to pinpoint a bug that has been in the program for a long time. The bug wasn't as apparent in earlier versions, but can occur in 2.04 now and then. Basically, when I detected draw-by-repetition, I wasn't resetting the length of the PV properly. If the program searched a move that led to a draw, the length of the PV should be the length to that move, but instead, it was set to the length of the last move searched which could have been several plies deeper. This meant the program could have bad or illegal moves in the PV in these cases causing all sorts of problems. The fixed version is on http://www.ssechess.com. Besides the bug fix, this version is pretty much the same as 2.04. Now that the bug is fixed though, I can implement all the good suggestions I have been receiving. :) Also, there is a forum (although not a great one) on my web page for SSEChessII discussions. Sam
