I agree with your pf call and flop check. Since you know there will be no low after the turn card, I would raise. If he's filled a boat you will be re-raised. If he has two pair you might scare him off not affording him the opportunity to fill. If on a flush draw he won't leave but you will know if he hits on the river.

I agree that in the end it will most likely be the same amount of chips, but if he folds better in your stack than his.
