        Specified by:
        worth in class TwoPlayerSearchable<TwoPlayerMove,​B extends GoMokuBoard>
        Parameters:
        lastMove - the last move made
        weights - the polynomial weights to use in the polynomial evaluation function
        Returns:
        the lastMoves value modified by the value add of the new move. a large positive value means that the move is good from player1's viewpoint

        Consider both our moves and opponent moves that result in wins. Opponent moves that result in a win should be blocked.
        Parameters:
        lastMove - the last move made
        weights - the polynomial weights to use in the polynomial evaluation function
        Returns:
        Set of moves the moves that result in a certain win or a certain loss.
