I've been following along. I'll add one thing to stax's evaluation.

I would open AQo UTG because I'm generally ahead of the flat calling range my opp will have. Generally at these stakes, they 3b w/ AK, KK+ leaving me tied/ahead on Axx or Qxx boards when opp flats. I'm way behind most any 3b range, so I can comfortably open-fold-to-3b.

I also suggest cbetting very carefully with AQ when catching air. I play this fit-or-fold primarily, though some dry boards with lots of gaps between cards I will cbet on. Examples might include K73 2-suited, T42 rainbow or 942 rainbow. Any time I cbet air, I have to realize about the ONLY thing opp can continue with is an overpair to the board or a set, so I'm extremely unlikely to 2 barrel without a seriously good read.

As stax mentioned, I'm looking to pick up my 0 - 1 postflop bets when I'm likely to be ahead, and I'm ditching to any serious pressure.
