What have you seen him do this with before?

Do you know if he would call a single raise preflop with JJ, or would he 3-bet it (with a PFR of 9 I think he would call)?

He's tight preflop, but does he call loosely postflop? I could see this guy calling preflop with QTs.

Has he shown a tendency to not fold to c-bets? Have you been c-betting heavily prior to this hand?

If you have seen evidence that he would consider TPTK, AA, or two pair a big enough hand to slowplay on the flop with, shove the turn. On the other hand, he is aggressive with less than a set but holds off until the turn to get aggressive with his sets, you've got a problem (KK, 99). If he won't give up on a decent PP just because there is one overcard on the board, you could very well be in trouble (I can see a lot of players doing this with JJ). Either way, I would go to showdown with this one, even if I had to call a shove.
