QQ in 4 bet pot 100nl deep

[emKay]

At first you cannot call the 4bet pf when you're not willing to get it in on that flop. It should only be a matter of how to get it in. Simply checkraising all in isn't bad I think, however given your image I like to give villain the opportunity to rebluff you with his AK, either by donking or by mincheckraising. You should have a read that he is getting annoyed by you in order to do that. And if you suspect he may call with AK, of course just crai.
