AK early 4-bet, 5 bet shove by Big blind

[KinkyKid]

He raises to $14.50 on the 3bet and you only pop it to $36? Your playing a difficult hand OOP. I agree with a lot of people that say to just call his 3bet. If you do 4bet, I'd raise it up to $45. Of course, this makes your call much easier. We also don't know your image right now...Any history with you two? You are sitting two seats to his left.
