As played I'd be folding the river, but I'd definitely pot the turn. You are ahead of anything but JT, but there are straight and flush possibilities to worry about.

From villain's point of view, if I have a flush or open-ended draw here, I have a 20% chance of making my hand. I figure, I can usually get a call for at least the same bet again if I make my hand. A pot-sized bet, puts me into -EV. I'd need to be comfortable, you would call a river bet of twice the turn bet, to make my play profitable.
