In Response To: gnu says take? (Tad Bright)

I had a machine open because someone has not dragged their hungover ass over to send me some more rollout positions - here are the results after 241 games. I think that the reason this position feels worse than it is is because white does not have a builder on the 6.

The score (after 0 games) is: gnubg 0, user 0 (match to 3 points)

Move number 2: gnubg on roll, cube decision?

gnubg	135
user	152
Position ID: 4HOHAUE21okBQg Match ID: MAFgAAAAAAAA

• gnubg doubles

Cube decision
Rollout cubeless equity		+0.637	(Money: +0.520)

2.	Double, pass	+1.000	+0.106
3.	No double	+0.677	-0.217
Proper cube action:		Double, take
