Did I puss out on the flop? What is my line here? His PFR is on the low side so I'm putting him TT-AA, AK/AQ, and AJs/ATs/KQs.

There are many more combinations of hands I beat than hands I'm behind, plus I have 2 outs to a set and BDSD and BDFD if he does have JJ-AA. Given that, what is the standard play here? I think I should have 3-bet the flop.
