Firstly: Dont limp preflop, especially not on the button. If your hand is strong enough to play in the first place, then you should be raising with it. If it's not good enough to raise with, then fold.

Post flop: I like how you played this hand. Flop raising feels really bad on a draw heavy board like this. It's much better to call and raise a blank turn (and fold if the turn card completes a draw with UTG betting in to you again).

It's unlikely but possible you're against top set or middle set. It's hard to put someone on bottom set because 66 isn't a hand a lot of people would automatically play from UTG. I would rather imagine they are on the draw here, though typically I expect they would slow down on the turn.

I'm guessing you might have gotten them to fold QT as well here since your stats are pretty tight and passive (PFR 15, 3 bet of 5) so your opponent probably thinks you're not capable of bluffraising and therefore your raising range on the turn crushes him.

Yeah he tanked for a really long time so its very possible you are right....(not a limp btw he just minraised)
