Walter Montego: This to me means either way of moving the last man off is OK by the rules.

Not for me.. Law 17 definitely says "Law 13 applies here as in all other situations". Doesn't that mean that you cannot bear off by breaking the Law 13, "Plays must be made for both dice if possible"?

>If I use the 4 and bear my last man off, the game
>is over by Law

As I pointed out, according to Law 17 referring to Law 13, you cannot bear out with 4 without first using 1, because you CAN use both dice.
