[Cry Me A River]

IMHO.

Playing AQs preflop against a raise is either a fold (vs a nit or OOP [except blind steals]) or a 3-bet (pretty much any other time).

Otherwise you're apt to get yourself in trouble. AQ is not a hand I want to go to war with on an A high flop after a PFR because villain is going to have AK a lot. By 3-betting we gain a ton of information. Most villains will fold AJ/AT (or worse) to a 3-bet. So if we see a flop and there's an ace, and villain still wants to get frisky we can be pretty sure our TP is no good.

OTOH, if we just call and villain wants to throw down on an ace-high flop, we have no idea if we're up against AJ or AK and things can get messy, fast.

There are some special cases where I could see just calling a raise with AQ (implied odds versus a whole bunch of calling stations who want call pf 3-bets) but generally I think it's raise or fold.
