This one's probably obvious...

Grunch.

I'm not 3 betting here. It looks like a slowplayed AQ to me. He's only sLAP so he isn't raising pure trash in EP and I don't see him raising here as a bluff, I'd guess top pair or better (and probably better). I think the better question is call down or fold as opposed to 3 bet. The call down is offering us 9.75:2 (accounting for rake and assuming he bets the river). We need to be good just over 20% of the time to make it the right play. I think it's close but I'll call down without a better read.
