Preflop, I think a fold is out of the question and I'm left with flatting, 4betting, or if I really reach for it, 4bet jamming. His raise isn't so big that the jam seems natural.

My bet size made sense at the time and now seems way too small so their monster raise.

Questions:
(1) What types of ranges do we give villain?

(2) What calling range do we give this type villain? Will the range be inelastic over reasonable 4 bet sizes? More and more I think so. Thus I think I should've raised a couple more or just flat-called.

(3) Not surprisingly, the solver balances betting and checking the flop with this hand. It also favors a larger bet. I don't think that's necessary against a villain who is unlikely to bluff. However, it also check folds. If I play this as 100% check, should I still fold it?
