I am not a programmer, but in such cases I wouldn't like to be one. >Kurt > >Homepage Kurt & Rolf: http://www.beepworld.de/members39/utzinger I did not test chessmaster but I suspect that a lot of program will evaluate statically that white has better king safety so increasing king safety scores may encourage them to get this position. Black has no pawns near the king. Uri
