50NL: 2 3 bet or not 2 3 bet

[Specialwon]

I've taken to 3 betting a good deal more and I'm seeing some very good results from it. Is this hand a step too far, or an ideal squeeze for my hand?

Hero 3bets to (say) $12?

UTG is a tight regular, 12 / 6, positionally aware. He has around 1500+ hands on me and knows that I have been stepping up my 3 bets a lot recently. He would maybe expect my 3bet range to be TT+ AQs+, something like that. His calling / raising range is probably JJ+, AK+. The others are unknowns.

My reasons for maybe NOT 3 betting are:

1. This REALLY looks like a squeeze, so UTG may call even lighter than that.

3. I am OOP for the rest of the hand.

Thoughts?
