I'm new to this, so take that as you will.

If he's passive, I'm 3betting pf in position with the hope of taking it down. Any time I 3bet and get called, I'm up against AK at the worst and a good chance of being against a bigger pair. I can just fold pf to a 4bet, since he'll only be doing it with AA/KK/maybe QQ or AK, but the times he flat calls its all those hands plus maybe TT+ and AQs+. Feel free to throw some other hands in there for fun, but if I 3bet and get called, its by something that's got me at a flip or worse, right?

If I flat call, his range widens, but how much? I think its hard to tell really, but if he seems passive and he's opening UTG, that gives us a direction. Its probably not Ax and probably something not something like KT. Your flop raise might fold out a lot, or all, of the Ax hands up to AK, but once he 3bets you're toast. You called pf in position, raised a very drawy flop in position, and he wants to get it in. He's either daring you to shove on a draw or he's got top pair beat, at the very least.

Because of all that, I don't think you have any fold equity. I don't think players at this level are good at laying down TPTK here, much less AA or KK, so I'm not sure what you're hoping to fold. Between your pf flat call and your flop raise, you're repping either a huge hand or a decent hand plus a draw, and he doesn't care.
