What is the best move in a fail high condition? Maybe I don't understand but it seems like a fail high position is one where no successor move has beat alpha. This is to say, alpha is the value of the best move in this position and none of the successors beat it. Now that I have searched this node and determined it is a fail high, how do I store the "best" move in the hash table when there is no best move? It seems to me that only if the alpha < move < beta should I store a move in the hash table...?
