AK Utg

Well, pre is ok. Flop as well. Turn is pretty hard. It should be probably fold. I don´t think we are often ahead there. However I think it´s close, because AK with pair is basically monster.

I would play it just like you did.
Villain probably doesn't 3bet you with 99 or 22. He should have pretty strong range. Only realistic hand that beats us is AA and there is only 1 combo. You might very well be splitting against AK and if villain is fishy he will have something like AQ. Or he might be tilting and shoving KK?

In my opinion against unknown opponent you can't fold TPTK in 3bet pot on the board like that, so you played it well. I think we often win against AQ, AJ and some crazy bluffs with air here. I would fold OTT only when I know opponent very well.

Nice hand Sir.
Sometimes you may look into A9s, ATs which had been preflop raised as a bluff. (A2s is blocked)

I would play it the same however I expect mostly a draw here.
