3-ply/XGR rollout: stronger rollout requested

In Response To: Break anchor to hit? #5 (Timothy Chow)

I believe that this is one of the most difficult problems in this series. I've included 3-ply/XGR rollouts for both Jacoby and no Jacoby below, and they show a significant difference. It's possible that XGR is screwing up the cube action in the next couple of turns, so I'd appreciate it if someone with a better computer will re-roll these with, say, XGR+ for the first four or five cube decisions. Regardless, hitting is a serious candidate here, which I found very surprising despite Blue's race deficit.
