AQo online 15-30 against unknown

[Pot-A]

Eh, this kind of flop just sucks - you don't like it, but you can't just check-fold every time either. I don't like the flop bet very much, since fishy MP3 will probably tie himself in with just about any two cards. With a non-fish the bet is fine since he'll be worried about putting in two more to see the turn.

I'd probably checkraise the flop and bet out on the turn. This will put more pressure on fishy and give CO a reason to lay down a hand like AK. If he raises you on the turn you can check-fold unimproved on the river.
