[Bug-gnubg] idea for faster rollout cube decision

[Robert-Jan Veldhuizen]

Quite often I find myself rolling out a cube decision where I'm only 
interested in one of the two rows of results. Sometimes the double is clear 
and it's just the take decision I'm interested in (bottom row). At other 
times it's a trivial pass but might be too good and I'm only interested in 
the No Double equity (top row).

It would be nice to have a feature to just do either of the two rollouts 
peformed by a rollout cube decision. In the Annotation window, I could 
imagine a button for "rollout no double only" for the doubler's turn, and 
if there's an actual double, a button for "rollout double/take only" for 
the taker/passer's turn.

Especially for close too good decisions (but huge passes) this would gain a 
lot of time (more than a factor 2 even) as they'll often be passed later 
anyway, sometimes right on the next turn. Right now though the rollout 
would spend a lot of time with the cube being taken and the game being 
played until the end or until the very unlikely recube/drop.

Cheers,
