I'd usually call with JJ pre flop against a UTG raise, if 4bet I'm not loving life assuming they are a reg. Post flop I like your line, really hard to call the river as we don't beat much and I'm expecting them to check back lower PP quite often opposed to turning them into bluffs.

Pre: I would not be a fan of flatting JJ here so I like yout fourbet.

Flop: Checking seems OK here, betting small is another option though for sure.

Turn: After villain checks back flop we should have the best hand here very often, betting gets value from smaller PP's and if we check we can potentiall induce bluffs from unimproved Ax type hands so either option is available, I think my preference is the bet though.

River: Pretty gross spot, I can't put villain on much of a range here as I would have expected most hands to be checking back here. Folding seems best as I can't think of a hand where villain is likely to be bluffing with.

Looks well played to me.

C betting flop looks too thin.

Turn value bet looks fine after both players have indicated they shouldn't have a queen.

River is a bad card. I wouldn't put it past BTN to float your turn bet with AK which makes sense with him cold calling your 3 bet pre. He shouldn't have any non Ax floats in his range on the river given the action making it an easy fold.
