Do you 4-bet AA or KK?

I think a lot of it would depend on table image and if he's 3-bet you before.

I'd be more inclined to 4-bet KK than AA.

My usual line is to smooth call the 3-bet with AA however

The best time to do it is when it looks like it is out of frustration from being 3 bet. 4 bet shoving makes you look more tilted and your range look wider...although sometimes my range is wider on a 4 bet shove, which is why I throw AA and KK into that mix as well sometimes.
