AK - where to fold with TPTK?

[1fineday]

Villain is 17/14/5.48 TAG
It's obvious Hero made a mistake calling down to the SD, but what would you change in this hand?
I think folding to flop min raise and calling flop minraise and folding to turn bet are both good ways to play this one. But what play is better?
