Best Backgammon End Game

This started as a challenge to see how many of my pieces I could get in the bar. I managed to not only get all of them hit, but to block all of the spots in the computer's home. Trailing by 289 points with 13 of his pieces off the board, I doubled. Computer ceded. Sweet. And a little disappointing... it thought I would win at this point, would I have? It would have been fun to try to roll my prime all the way home (advance my block of six one step at a time).
