Its something Ian and I argued about a few times. I just dont feel like we need to slowplay PF at 50nl. I'm all for shipping AA and KK preflop. AK I'll try to ship if I'm OOP, but IP I use my judgement.
As for the AK hand in question. Tough spot. I had a similar one last night where I isolated a shortstack laggy fish for 22bbs with AKs and the nit SB shipped it in. I nearly folded that but chose to call and flipped well v's QQ. Its kinda borderline though. Your image probably comes into the decision.
