Sucks to be OOP for the rest of this hand. The only hand in CO's range that we are really scared of is 77 ldo. But this flop doesn't seem wet enough that he should feel that he has to protect that here. Which leaves semi-bluffs with reasonable broadways (AK, AQ, AJ, KQ, KJ, JT) and air. With that in mind, and your image, I like a call on the flop, with a check/push on the turn.
