Had played only a few hands with villain. Hadn't seen anything overly fishy.

My main question is regarding PF action. Villain 3bets OOP. I put their range at TT+, AQs, AK. Since I'm on the BTN, I'm thinking I don't mind seeing a flop.

On flop, villian bets out. Now I have their range at QQ-AA with the slight possibility of TT. It looks to me like villain is attached to their hand, so I 3bet. Sure enough, the money got AI.

How does it look? My main struggle is with the PF. My instinct is to get it AI PF. I'm not sure that's always the case if one is in position.
