check call river

-he folds if he has nothing
-he probably calls if he has you beat with A-10 or shit (a 10 not in his range IMO unless it's pocket 10's)
-if he has a pocket pair less than 9's, he might bet himself and you can call winning a bet. I think he folds 55-66-77-88
-if he has nothing, he might bluff to take the pot on a river, winning yourself a bet
-His raises probably don't include a Jack UTG ( I doubt AJ ) unless it's pocket J's. This hand screams AK - AQ

flop is ok. Bet turn maybe, 15$, that's the only thing I would of done differently. The only hand he calls is overpair or with a J on the turn if you bet 15$.

so overall, I think we have the best hand here, and check calling IMO will earn us an extra bet more often than if we bet ourselves.
