$16 - AK bubble, bigstack v bigstack

[Jago]

I think pf is a fold, but villain recently acquired his stack and i suspect have been raising quite liberally so I decided to call and bet/shove any A/K flop. On the flop I decided to bet 1k to signal ive hit the ace. Once Villain minraised i felt pretty sick but chose to push anyway.
