I think it really depends on your read. These loose passive types can be observed to never cheskraise the turn without two pair or better. If he is one of those, I think you can get away from it on the river. If the board pairs you may counterfeit him and then have a call. Three betting the turn is pretty bad against this player because if he caps you miss out on a chance to spike a K on the river and you are ahead here very rarely. If your read is not super solid, tow the standard line and call down and watch the pot shipped to him.
