Based on your description of villain, as having a tendency to beat up on limpers etc, I'd say villain is aggro. Certainly aggro enough to be jamming Axcc here always, QJ/JTcc, and maybe even KQ (though far less likely).

I'm snap calling this (not literally, but in my mind it's a snap call, and then I wait a few seconds before actually calling. I don't think you should EVER ACTUALLY snap call in game. It gives villain too much information about how you view relative hand strength. )

I don't mind flatting pre vs an utg open.
