If a chosen move wins 100% of the time, and the program sees a clear solution, it is a winning move. A winning move cannot be said to be incorrect. It has exactly the same value as a winning move to a shorter solution. >If there are two equal ways to win, then yes, >either is correct.

Otherwise >each WAC position probably has _multiple_ correct solutions... If a problem is not proven all the way to win/loss/draw then it is really open. If there are 10 moves that lead to a definite win, then all ten moves are solution moves. Including crazy moves like tossing a queen for a tablebase simplification.
