In Response To: Rollout (playBunny)

Thank you very much! Curiously, in the truncated rollout below, 20/15 13/11 doesn't fare so well.

I'm still at a loss as to how to sort through the options in this position. FWIW I tried 20/13 OTB.

		White is Player 2 score: 0 pip: 141 Money session Jacoby pip: 162 score: 0 Blue is Player 1
