I can't see anything other than a 3 bet on this turn and am surprised there is actually debate about this. Unless he's a donk or a maniac he won't cap this turn without JT or a set.

If you raised preflop and 3 bet on a AQ2 flop and bet again on a K turn it takes a hell of a player (or a donk) to cap it when you 3 bet with less than JT or a set.

IF he caps the turn, in theory it would be shouldn't be that difficult a fold (I'd still probably call though even if all signs point not too, I'm not quite that player yet 90% of the time).

if your betting indicates AK and he knows it and still caps the turn knowing you won't fold AK or AQ (this being limit and assured of a calldown). I seriously think you can 3 bet this and if he caps it fold if you don't fill up.
