UTG bets $7200

hmmmmm

What would you do? What hands can I really put him on? AA or KK goes all in preflop right? I think JJ goes all-in post flop. Seems like QQ or AK to me.

I really really appreciate any advice here. I have a strong feeling I made a couple of mistakes. I've been kicking myself over this hand for days. My thinking with the preflop raise was that UTG was just playing some big stack poker. I wanted to show him I had a hand so he could just get out of the way. Really I was targeting some of the other low stacks at the table. Dumb I know. I was a little shell-shocked when he called.
