4bet bluff vs 2p2er flops top pair

[aislephive]

Villain is Pudge_714, got him at 25/21 over a big datamined sample. No history that I can recall though except he 3bet me once before blind on blind and I folded. My image is probably 21/18 aggro or something.

Preflop is whatever, he 3bets a lot and I can likely get him off a lot of hands since we don't yet have any history. I expect him to fold everything but AK/JJ+. Not sure what exactly he is calling my 4bet with, I'm guessing stuff like 99-QQ maybe?

What should I do on the flop? If you check how do you respond to a $150 flop bet? And if I bet I've gotta call a shove, I think.
