The fix didn't seem to work for me.  This looks to me like it could be the rollout settings (truncating because it's in the database or non-cubeful)?

It seems that checker play rollouts started from the command line interface do not take into account that the opponent can double at his next turn.

For instance, if one rolls out the 2-rolls position (position ID GwAAYAMAAAAAAA, centered cube, 2-1 to play) from the GUI, one gets, as expected, the following cubeful equities :
2/off 1/off  0.72
2/off 2/1   -1.00 (since opp. will double us out)

On the other hand, if one types the following commands in gnubg -t or loads them in the GUI with Open Commands :

set player 0 human
set player 1 human
new session
set board GwAAYAMAAAAAAA
roll        (choose 2 1 when asked)
hint
rollout =1 =2

one gets as cubeful equities :
2/off 1/off  0.72
2/off 2/1   -0.71 (opp. didn't double!)
