AKs on a scary flop

[skunkworks]

Game has been loose but occasionally aggressive. MP2 is a little weak. I've won a few hands at this table with premiums.

I bet out here and it comes back two more to me. I'm surprised by the action, and without really thinking, I hit the call button.

Hero checks, MP3 checks, CO bets, Hero folds, MP3 calls.


The more I think about this hand, the more I dislike my turn fold. Once I call the 3-bet on the flop, I figure that I'm committed to the pot yet I fold on the next street. Is this the correct way to think?

How should I have played this?
