Villain is loose.
After he re-raised me, I stalled for about 20seconds and thought about it...I thought well if i RR him back higher it gives my hand away. I also paused to make him think I am calling with a mediocre hand.

I checked the flop hoping that he would bet...only hand that beats me here is JJ so i was a little bit worried because after I raised him, he 3 bet me AI with no hesitation.

How would you guys play this hand againt a loose agg. player? Did I make mistakes? should I 3 bet PF? Lead out on the flop?
