danoschek: I still have no idea what you mean. You can already swap the dice to use them in the order you choose; there is a glitch on this site which allows a player to use the smaller of two dice, if either but not both can be used; also, to use one die in such a way that the other cannot be used, even though there is a move available that uses both. Is that what you are talking about?
Are you suggesting a rule that allows bearing off only from the highest possible point? (Or that you can't bear off from a point if a higher point still has checkers?) That is not a standard backgammon rule, at least not in the international game.
