multiway 3-bet pot w/KK 1000NL

[jj12]

UTG is a spewy tag (22/17/3). The cold caller is (33/15/2) over a 200 hand sample. I don't know much about his game. However his stats suggest that while he may have some leaks he is not too weak of a player so I think AQ should be discounted. He instacalled my three bet. Do you play this in any other way? I just feel I am running into AA/QQ too often here.
