Thanks for the comments guys. I shoved on him. He called with JJ and my hand held. At the time, I was also including pretty much any pocket pair within his 3bet range due to the very small sample size so I was worried slightly about him having hit a set.
In the end, I decided that him hitting a set was a very small part of his range and (as MikeMaloney said) I was only behind two other hands, AA and KK.
