TT hand, 50nl

[Stork]

villain has only been here alittle while, but has been raising a decent amount preflop, especially when he is in the big blind and I complete my small blind. So far I've just been folding to those.

Villain has 61.45, I cover. 6-max game, btw.

I raise to 2 with black tens in the cutoff, villain makes it 5 to go on the button. Blinds get out of the way and we take the flop heads up.

Flop is 6 3 7 with two hearts.
I check, villain bets 5 into the 10 pot. I call.

Turn: Ac
I think about betting 3/4s pot, but decide to check. Villain insta-pots it for 20, I fold. Ya?
