Villain is 27/20 and fairly passive postflop, including with cbets. He has been stealing almost 50%. He doesn't seem crazy.

When he checks back such a coordinated turn I feel like he almost never has a set/AA/KK/QQ. I don't think he would call preflop with KQ and certainly not flop. He probably doesn't call flop with AQ very often.

I feel like he has TT/JJ very often after the flop call/turn check. Can I rep AQ/KQ here and get a fold?
