tough hand OOP. preflop and flop are fine. turn was a pretty bad card and i think a fold would be okay. on a 2/3/4/5/6/8/9/K turn you would have to call another barrel. then divine whether to fold or call the river.
if you were 4betting AQ he should be going with 88-TT for stacks pretty often, and folding over half of his 3bet range (in this scenario his 3bet% is probably 10-12%).
Hand 0: 34.143% { AQo }
Hand 1: 65.857% { 88+, AKs, AKo } (--4.4% of total range)
