def listen(self, on_move_request):
        """
        Waits a connection from a remote player via socket connection.
        If the socket connection fails will NOT handle exceptions.

        Raises BadRequestError, if the client request is not valid
        or the client is not the opponent.

        Blocking, can be cancelled from another thread by calling
        stop() on the object.

        When a valid request is made, on_move_request function is called
        with the name of the opponent and the board he sent.
        The function should return a move for the board.
        The return value of the function is not checked! If it is
        NOT a valid move, it WILL BE sent to the client.
