Generally going to be a 3bet for value to $6, but villain dependant ofc. AQ is a top 5% hand and people will generally continue with worse and dominated holdings.

Squeezing to 4x oop is better than 3x or 3.5x imo: we get the pot HU more often and extract more value. Taking it down pre is obviously fine too.

You're going to want to mix in some bluffs in this spot too. A better question to ask yourself would be what range you would squeeze in this spot and under what conditions would you want to do so? Then apply the same questions to being on the btn vs co and mp, etc.
