I wanted to know relevant rollout setting in this type position.
Thus, I experimented in a lot of settings.

And I found that XG need wide search interval in this type position.

I tried to do XGR+ Gigantic rollout, but it is too heavy. So, I did XGR Gigantic and 4ply Gigantic rollout at the moment.

I did grandmaster full rollout by gnubg.

1. Rollout bar/18 Eq.: -0.551

0.345 0.085 0.030 - 0.655 0.000 0.000 CL -0.196 CF -0.551

[0.002 0.002 0.001 - 0.002 0.000 0.000 CL 0.005 CF 0.008]

2. Rollout bar/21 4/1* Eq.: -0.608 ( -0.058)

0.332 0.069 0.020 - 0.668 0.000 0.000 CL -0.246 CF -0.608

[0.003 0.002 0.001 - 0.003 0.000 0.000 CL 0.006 CF 0.010]

Maybe gnubg is better than xg in this type position. It took only 8 hours.

I am trying to do XGR+ Gigantic rollout.
