My initial thought was to bet out on the flop to push out the button if CO will raise with AK, but if button is truly that bad, let him stick around.

I think I call the flop bet and donk the turn, provided it's not an ace or a club. I think I'd have to fold the turn if CO raised. I would c/f an ace on the turn. For a typical TAG, I can't think of a lot of 3-betting hands you're ahead of.

Now, if you think CO's opinion of you isn't very high (maybe you've been raising a lot PF and stealing or not going to showdown), his range widens considerably and I'd like to get to showdown cheaply.

edit: 'cause I can't read...
