According to the rollout below, if we take away White's good 6's and change the score to gammon go, then clearing the 7pt is indicated.

Caveat: In this variant, White has a tricky decision to make if she rolls an immediate 63 64 65. If XG 3-ply is misplaying these rolls, then obviously that will affect the rollout. My preliminary investigation, however, indicates that if anything, XG 3-ply is misplaying these rolls after Black clears the 6pt (breaking the midpoint rather than the anchor). So my prediction is that a stronger rollout will actually widen the gap between the two plays.

		White is Player 1 score: 1 pip: 117 2 point match Crawford pip: 74 score: 0 Blue is Player 2
