overplayed TPTK (AK)? - 50NL 6max

[starvs]

UTG is 38/12 over 50 hands or so, no real read besides that, but he hasn't gotten out of line.

I probably should have re raised pre-flop. I don't like to re-raise AK out of position all the time, but since this was a min raise, it probably would have been a good idea, but that really isn't the crux of the hand. Should I have 3-bet the flop, lead the turn, or check raised the turn as I did? I feel like sometimes I lay down TPTK to much, and some times I just go nuts with it, and each time is usually a reaction to what I did last hand with TPTK, if it didn't work.
