20-40 TOP pair

[Mikey]

i'm playing in a 20-40 game and its a pretty ok lineup.

I'm UTG and pick up AcKc UTG and limp.

Next person limps.

Mid position limps.

BB checks.

4 handed.

The flop is Kh 7h 2d.

BB checks.
I check because the person to my left has chips in his hand and is ready to bet.

He bets, next guy calls, BB folds.
I checkraise, the original bettor folds, and now the caller reraises. I call.

Turn is a Qh.

What is my play for the rest of the hand?
