I only fold if he is world class player who has a good read on you. Like a good player will call you with a pair up to Q there. When you bet the pot, he knows you have a big pair. So he can take some chances and slowplay his set
even though there is a flush draw out there.

However, with out a good read on you, how can he slow play a set on the flop with a flush draw out there? Most decent players will raise there set there. Moreover, if he had QQ how can he over bet the pot on the turn? He really has to know that you are not capable of laying down big pairs to make that kind of overbet.

I would call the turn and decide on the river. Most players will check the river if they were betting the turn with KK, JJ, TT or AQ and value bet a bigger hand.

The problem with calling on the turn is if he is good he will put you on AA or KK, so if he has a good read on you, he might make a big bluff bet on the river so it can get tricky.
