Hand is on Bovada. I'm just not sure what to do in these situations, especially vs. an UTG raise.

Hand plays out with UTG raising 3.5bbs, I flat TT on the button and everyone else folds...

Flop: 2d 3h 5c - He bets 3/4 pot and I call.

Turn: Kc - He bets 3/4 pot again. Do I call or fold here? I know he can barrel a lot of A-x stuff and possibly any of his air. I'm guessing my plan is to call turn and fold river. He has a lot of K-x in his UTG range but he probably has more combos of A-x that he's bluffing this turn with.

Hero ???
