does he appear to be positionally aware?
do you look like a nit to him?
would you ever 4b here?
this is probably a turn decision, you're basically asking how much he values AQ here, his line looks like QQ/KK/AA only. I mean, if you check-shoved the flop he might fold overpairs and call AQ cos blockers to top set (that's genuinely how some players think here). But I doubt it.
