The pot is too big to fold on the flop anyway considering you stack size. I mean you have 20% in PF. The BB pretty mych has to have a PP considering he cold called your RR PF. He may have a set but you cant fold with 50% of your stack in after your CB,

This is fine. If you're going to 3 bet with AK OOP then this is a flop you want to get it in on.

Also, bet more on the flop. Bet at least $4.
