Villain is 19/11/2.6 3B:4% over 450 hands. No reads.

My main concern is the turn play. Is it better to bet/fold turn (if so, what bet size?) and check behind river if he flats turn or check behind turn and call a medium sized bet on the river or bet/fold around 1/2 pot if its checked to us. I don't see him betting out 30 into 36 with KJ here and in general I don't see many 100NL people having air here.
