What happens if i can't go in Backgammon?

Answer 1

If you are blocked from taking a roll in full, then you must take the roll on one of the dice, and if there is a choice, it must be the larger roll. If both dice are blocked, the turn simply passes to the other player without you moving at all.

Example: you have a piece on your opponent's 1-point and he owns his 4-point. You roll 2-1, and none of your other pieces can move. You must move to his 3-point rather than his 2-point. If you roll 3-3 then you simply pass the turn.
