In Response To: What About this Cube Decision from Madison? -- OTB (Bill Riles)

I think I mentioned in Madison that I would have cubed.

Rollout shows technical ND on g11.

The score (after 0 games) is: White 5, Blue 7 (match to 9 points)

Move number 3: White on roll, cube decision?

White	120
Blue	36
Position ID: fl8BAADbbgMADA Match ID: MAEgAVAAOAAA

• White doubles

Alert: wrong double ( -0.0204)! [doubtful]
