Blue to play 11 (White will fan)

(5) You are guaranteed that if you hit, White will fan on her upcoming roll. In that case, how should you play double 1s (for money)?

I haven't rolled anything out, but according to XGR++ eval, the best move under the stated conditions is 24/23 8/7 4/3*(2). This play gives Blue a strong double (after White fans) and an equity of 0.709. See details below.

		White is Player 2 score: 0 pip: 158 Unlimited Game Jacoby Beaver pip: 143 score: 0 Blue is Player 1
