ATs flop and turn questions

[Guido]

Hi all,

I'm at my work so I don't know the exact stats of my opponent and this hand was from about a week ago. I did have a history against this oppenent where he stacked me with 67o against my aces on a A548 board on the turn where he c/r me all in and I called. I think he has a VP$IP of about 30% and a PFR of about 12%. Here's the hand and I wonder how I should have played it on both the flop and turn.

I called.
