FWIW, a GNUbg rollout sees the doubling decision closer than the take as well :

Match to 9 points - GNUbg 1, You 2

GNUbg	70
You	123
Position ID: u+0RAAKYbdsEAA Match ID: UQkgARAAEAAE

• You doubles

Cube decision
Rollout cubeless equity		+0.680	(Money: +0.687)
Cubeful equities:
1.	No double	+1.045
2.	Double, take	+1.332	+0.287
3.	Double, pass	+1.000	-0.045
Proper cube action:		Too good to redouble, pass (13.4%)
