Usually fold vs 4bet. The fishy sizing is designed to induce calls or a shove.

I like the squeeze but
Fold pre. I'd fold this even IP (if not BBvSB)
AP, I don't see how u can fold this postflop. If ur gonna fold AQ here, u shudn't have called.
Pre fold >>> Post flop AP > Folding turn.

I'd only flat AQs OOP on SBvBT 4b only against few opponents.

And I believe fish sizing that Disharmonist meant min-raise 4b pre.

Fold pre vs UTG. As played, fold turn - your perceived range is now Qx+, a card is terrible to be bluffing on, and Villain doesn't have any worse value hands that he can play like this. You're gonna run into QQ+ the vast majority of the time.

Easy fold you're just going to put yourself in a lot of tricky spots OOP by flatting here with really bad reverse implied odds

Easy fold preflop. As played I'm folding turn it's a bad card for him to bluff.

Easy squezze fold pre.

Im not squeezing suited combos, unless the btn is a rec
you look too strong considering that reggy utg is involved

Its close though, I'd prob still squeeze offsuit combos a lot
fold to a 4b, if youwanna continue, just jam (which wouldnt be by any means terrible fwiw)
