25NL - QQ vs overbet from nitty player.

[VLV]

Villain is 9.1/9.1/2 over only 22 hands, haven't seen much from him at all. I've been pretty active and am probably running something like 30/30/3.

I have $17.55 left. Villian paused before pushing.
What I'm thinking is: I would have been 4bet with AA/KK PF, as set would not over bet so much and would try and get as much value from me as possible, this line makes sense for something like TT,JJ or A9s. I can't really put him on any draw either since there are only GS there and I doubt he's doing this with a draw.
