I have taken all off my pieces of the board in a game of Crowded Backgammon. I was awarded 2 game points for a gammon. I am wondering why I did not receive 3 game points for a backgammon instead of a gammon, as my opponent still has two pieces on the bar. Nowhere can I find that having pieces on the bar, whether sent there or from the start of a game, does it say that I do not score a backgammon and get 3 game points.

So what gives?
