umm... what IS he likely to do this with? Nothing. In my experience, overbet pushes are usually AK or a small pocket pair that is too scared to play postflop. That's not to say his range isn't pretty wide, but I think you have to weight those hands more than others. I also don't think you can discount JJ+, as I have seen people overbet with everyone one of those hands as well. I don't think this is anywhere near close.
