Fold the flop. Normally you'd peel here if you were heads up, however, now's a good time to make a fold. The CO raised preflop, usually signaling he has a strong hand. You also have the button to act after you. This causes 2 problems:
1) Your overcard & backdoor outs aren't clean. If you hit an ace, you may still lose to AK/AQ/ect. If you make a running straight, you may split with another ace or lose to 6x. If you hit a ten, you still may lose to an overpair like JJ. You do not have as good a chance to win as you think you do in this situation.
2) The players to act behind you may raise (especially the CO). So while you think you're getting 11:1 pot odds
here, you could be getting as bad as 6:1 or even worse if the pot gets jammed. At 11:1 you have the pot odds
to call, but at 6:1 you probably do not.
So fold the flop.
The rest of the hand is played fine to me.
