4bet/folding with AQ is fine but I don't like doing it vs unknown, prefer regs who play with static ranges when 4bet. I would be folding pre-flop until I build some profile on the guy, can't see AQ being ev+ call in this spot.

Flop is a fold, would fold every time unless the bet was like 5-7bb.

It's a good hand to do it with but like Harvie I want a solid read on villain before I chance it. Villain's 3 bet size is huge too which makes me wary of trying it here.

On the flop how I play is related to how wide villain's 3 bet range is to begin with and what his c bet tendencies look like.We can obv float here a lot for this sizing if his range is super wide BTN vs CO

This is pretty much the top of your folding range so 4betting is obviously not the worst idea in the world but given the fact that you're out of position and you have limited info there's nothing wrong with just folding the hand for the time being.

As played, with limited info it's hard to do anything else than just fold.

Versus unknown I'd fold preflop, too much guesswork made worse by being OOP. Flop is a fold for me for similar reasons and folding preflop saves me the money and the headwork. Can't see my 4bet bluffing versus a large 3bet and an unknown range (but an assumed stronger one given the reraise size).
