Are rollouts still useful

There are certain types of positions that the bots are consistently off one way or the other. Even simple looking stuff. In holding games, XG tends to overrate the holding game side.
4-ply:
++ Eval:
Rollout:
Containment positions where you hit a late shot and are trying to contain that hit checker is another. It almost always underestimates the side doing the containing. Often by .1 or more. So you have to roll that stuff out. The rollout is probably a little suspect too, but it should certainly be more accurate than the ++ eval.
On the other hand, if the bot tells me I took a 1.2 in a blitz position, I'm not rolling that one out...
