I figured his range is something like TT-QQ here and he'd call with the sets. AA, KK might be in the range if he wants to get tricky and he'd call those, too.
I don't see any range here were we don't have the equity for the push. I guess no matter what villain has here the hand plays itself.
Equity vs QQ/JJ only is 42.5% and he can't really fold anything that connects with the board in any way

Standard, right?
