Villain's push doesn't make sense for a mediocre hand like Tp so it's either a semi-bluff with the FD or a made hand that beats you. I think you're beat here too often to call, he could easily have a boat, 7x or straight.

Anyways, could you explain why you would not 3-bet JJ pf? The problem when you don't do it is that it's hard to win any big pots because most of the time you'll only have that small overpair (heck, more often the board has an overcard and you have a middle pair). Varying your play is good but I don't see the merits in flat calling with JJ here unless your villain's pfr% is very low. I don't think JJ works well at all when you just flat call, too often you fold the best hand since JJ can't take much heat and it's hard to get much value when you do indeed have the best hand.
