OK, 1st big problem which is probably something I don't understand. The program fails low at the root resetting alpha to -INFINITY. You now make your first root move, and search with alpha now equal to -beta, and beta equal to -alpha, which makes beta equal to INFINITY. If you call a null move at this point, the null move window is INFINITY, INFINITY +1 which obviously does nothing but return a score of INFINITY which is greater or equal to beta ..... What am I doing wrong. Do you screen for this before doing a null move? William wbryant@ix.netcom.com
