alanback:  Another feature from DailyGammon which might be a bit more difficult to program, and which also reduces the need to swap dice, involves entering from the bar.   A player who must move his piece from the bar is not required to do this as his first move, as long as he does it during the current turn.  For example, I have a piece on the bar and the dice are 5-2.  I could enter with either the 5 or the 2, but I prefer to enter with the 2 and use the 5 elsewhere.  DG allows me to move the 5 first, after which the only permitted move will be to bring the piece on the bar in with the 2.  This does not effectively violate the rule requiring the piece to be entered from the bar before any other move is made, because the two moves are unrelated.
