Subject: SSEChessII 2.045 Released - Bug Fix Version

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.
