Really a terrible flop for your hand. Especially vs UTG range.
I don't really like betting flop to begin with with. But as played I fold to river shove. Either turning a weak hand into a bluff or checked back AQ I guess.

It's a wild bluff to make... In my experience without prior knowledge of your opponent, its best to fold these.

On the flop think it will depend on how much AQo you think hes flatting and strategy will shift. On the river, think AK will be a fold hard spot for people to bluff and think we will have better hands to call with.

I disagree with Adrian about the flop cbetting stratergy. It seems like a pretty clear high frequency small cbet to me. OTR they just have such an inbalance to value its pretty hard to find bluffs, for us to call we have to assume they can bluff ATs AJs QQ which I think is a longshot.

Shitty spot for sure, but the problem is he has 'something' and people dont usually bluff raise all in w 'something' - they would just bluff-catch

Probably mixing betting small/checking this flop with AK. Pure betting AA+. I think either choice with AK is ok.

I think you can maybe size down somewhat if the intention is to bet fold river. As played, fold is probably best. I think I would choose something more like $9 here.
