I'm guessing that I should have checked on the river (again).

My question is more about trying to get off a check raise on the flop or turn?
Considering I am ahead until I am behind, is that going to win me the pot or just let everyone check behind? I cant see MP1 betting bottom pair all that often.

Depends on the players I guess. Usually, no one will have caught a piece of a flop/turn like that, so if you think one of them is aggressive enough to likely to bet the scare-3flush on the turn, then maybe... but I think you're better off just betting out most of the time.

Checking the flop can be a disaster - they're often going to just check behind with overcards. JJ is too vulnerable to allow that to happen. I'd just bet out and hope someone tries a fancyplay free card move which allows me to 3-bet.

I think that you played it fine.
