Overbet 4-bet with AA any thoughts?

[_pairwin_]

So this is your first 4bet. I think a call PF and shove over the Cbet on the flop is pretty standard. There's only a select number of hands that are going to call/shove over especially if villian is a good player. I know its 2/4 but he could be squeezing here with a marginal hand, calling is much more +EV.

I normally do flat call behind here. But to mix it up i shoved, what ratios do you like to shove/call and do you prefer a shove or rasie to like 220
