Rollout with and without Jacoby

In Response To: Don't you hate it when you're outboarded? (Timothy Chow)

The rollouts with and without Jacoby are the other way around from what Neil and Casper predicted, so maybe someone should verify these results with XG. (I'm not totally sure I'm correctly handling the Jacoby option with GNU; when I want to turn Jacoby off I simply add a line "set jacoby off" to my rollout file.)

For good measure I'm including a variant position (with Jacoby) where White's 2 point is open. Hitting is clear then.
