AK when to fold?

[stretch22]

Dont know too much about villian. During this hand I couldn't stop looking at his name: uberfoo

I know I should have folded...but when?
bad bet after the flop?
check on the turn?
I'm wasnt really thinking but I guess I was trying to scare him away because i was so aggressive pre-flop and he was being passive up until the turn I thought he would fold. I have a bad habit of trying to get people to fold too much; after I start getting sick of playing I always try to push people around too much.

I can't tell if tonight I'm getting raped by the cards or if i am playing differently than usual...
