pocket JJ overplayed?

You have to 3bet this hand pre flop and I don't know what is his stats but raising from utg i expect alot of A's on his range so analysing the hand if you just check flop it doesn't seem a great mistake and try to call small bets.

Cumps

How many aces does he have that flats a 3b though, maybe a hand as AA, but other then that I would think he would almost push all his Ax that is going to play. I don't think a hand as Aq or Aj is flatting. But hey what do I know.

I don’t see many Ax hands in his 3bet call range except AK and maybe AA, but I don’t think you overplaying your hand here.

Why would it be wrong just to call his ISO-raise?

I like the pre flop play, but postflop I wouldn´t bet. As already mentioned, the chance is high that the raiser holds strong ace-combos or: maybe a higher pocket pair. On this flop no better hand will fold and no worse hand will call you. So: Just check postflop. On this flop I personally would play check-call or even check-fold. This is a very bad flop for JJ.

preflop same,you are ahead of his range and don't want to give limper too good odds.

I play c/c flop and c/f turn because I don't belive he is 2nd barreling me here without A.
