	 * to cast the Move to its true class.
	 *
	 * Casting can be an expensive process.  When time is an issue, eg for
	 * games that try thousands of moves in order to determine the best one, 
	 * it is better to avoid casting.
	 *
	 * The clever programmer may also use the toString() method to 
	 * represent the move as a String.
