Pre Flop: Hero is UTG+2 with A K
2 folds, Hero raises to $24, 1 fold, MP2 calls $24, CO calls $24, 3 folds

Flop: ($81.00) A K 3 (3 players)
Hero bets $48, MP2 folds, CO raises to $138

CO seemed fairly tight, he was open limping small PP's I'm pretty sure, but he was a multitabling reg it seemed (I usually don't play at these hours). MP2 is random pretty-bad fish.
So, like, where do I go from here? Do I call and pray for A or K, and if one comes c/rAI, or do I just let it go right now? His range is pretty much 33-flush right?

ps. not a level- I just suck

why the crappy flop bet size?

and you have no stats, just a fairly general "view". could this be AK, AQ with clubs?

I feel as if my bet sizing on the flop achieves the same as what any other bet does. Q will flatcall, but the hand will be almost face up to me from the rock, and he's still paying a decent price. If the fish calls, I can valuetown him on the next two streets with bigger bets (if he has an ace, or if he has Q).

I think he would flatcall AQ, but AK I guess is also in his range, despite being very unlikely (?). I'm positive he'd raise KK AA pf(who doesn't?).

Even if it is- IMO he has a variety of flushes or a set which leave me drawing thinly, a top 2 pair which leaves me splitting, or AQ which has me ahead by a fair bit. Mathematically I'd think it's a fold, right? or still go broke anyway...
