Simplify Overload condition Extend the bonus for Overload to cases where our side has more than one attacker to a non pawn piece. Based on an idea by Bryan in the forum. For instance, now black gets the overload bonus in this position: 8/5R1k/6pb/p6p/P1N4P/1Pp5/2K3P1/2N4r b - - 6 46 because two black pieces are attacking the knight on c1 that is defended only by the king.
