sry, my bad, thought we were talking about smth else
it's even more straight forward when you face a 3b on the btn
you can straight up fold AJo/AQo if you happen to know the blind is nitty with 3b in these re-steal spots
otherwise you really should be calling these hands
the hands you want to 4b should be really polarized, i.e. whatever you want to 4b/gii for fat value and hands with blockers, that are not good enough to call, but that punish your opp for 3b too much oop.
I 4b ATo as a standard in these spots for instance because I'm never calling it and it blocks AK/AA/TT. vs very aggressive 3bettors I include A5o and A4o, not the suited versions, since those are good enough to call ip
Don't get too crazy with defending offsuit broadways tho, AJo and KQo are bottom of the range and even these can be folded vs a nit.
