Just so I make sure I have this correct, here are the current "problems" with the backgammon game.
1) If a player can, they have to use both dice. If that requires him moving a certain piece first to make sure the 2nd dice can be used, it must be done. If a piece can be moved to block the use of the 2nd dice, that move should be forbidden so both dice are used.
2) If A player can only use one of this dice, but has a choice of which dice to use - they must use the higher of the 2 dice.
