How to play this against a TAG?

Hard spot, if u check he'd prob bet his FD trying to represent the str8 when he gets the chance. Is he folding a 2 pair to a bet in this spot? if he'd only call you with set's (which he might have to think is a drawing hand), made str8 and a good FD i'd bet it, if not i'd check and take it from there.
