What is the ugliest thing about this hand?

Plz tell me what you hate the most about my line here. It shouldn’t be hard ; there’s a lot of butchering going on… I have a loose image, as always…

Squeezer is decent, aware player. SunTzu is donk bigstack running hot.

I think either calling pf or folding on the turn.

I think calling preflop with AKs is the worst. I think you need a read to know that a opp is squeezing here, and then I would probably 4-bet preflop (also to force suntzu out and get HU) - but honestly I dont play in such aggro games yet, so I dont know the correct answer tbh.

Turn fold is obviously fine because:
- you have suntzu yet to act, and he might very well have 2pair+ here.
- a lot of TAGs squeeze with suiced connectors and this flop+turn is hitting a lot of those hand really hard.

I didn't like the turn fold mostly because the bet is less than 1/2 pot (almost 1/3 pot I think). villain might be semi bluffing or even have a worse hand at this point - I'm just not sure you can be like >75% sure TPTK is beat. And I am not worrying about suntru much since he's a donk.
