I don't know, I've had some interesting experiences with experimenting between 4 betting/3 betting AA

- on the 4th raise most people assume AA or KK and fold, or just setmine you. Against a looser opponent willing to part with chips or shorty, I happily 4 bet. Against a nit, I consider calling a 3bet.

- By calling the 3 bet, they don't know your hand

Three times recently, someone did this to me with AA or KK when I had AJs-AKs and got fantastic value they'd never have gotten from me if they had 4 bet -- I dumped like 1/3 stack on each when I would have mucked to a 4 bet.

so I dunno, I see good points in doing it either way, really I think each strategy is good depending on opponent.

with someone aggro I like to let them think they're in control and just call their 3rd bet.
