Scale contempt factor to zero at endgame Contempt Factor is more effective at opening/middle game and seems harmful at endgame phase. See: http://chessprogramming.wikispaces.com/Contempt+Factor http://web.archive.org/web/20070707023203/www.brucemo.com/compchess/programming/contempt.htm Therefore we scale down the contempt factor while going on with the game so to reach zero at endgame phase. No functional change.
