In Response To: On Bar Cube Decision (Dave)

Huge double, close take. (Looks like monster take at $-play and probably not a cube, but the closer decisions need rollouts with the proper score, etc.)

The score (after 0 games) is: White 12, Blue 6 (match to 21 points)

Move number 5: Blue on roll, cube decision?

Pip counts: White 116, Blue 121
