I folded AK preflop

Villain was a 60/3 or something very similar to that. Didn't see a preflop raise from him in forever. Was this fold justified?

Standard against 3% PFR. About 1 out of 4 of his possible holdings have you dominated, the others are coin flips. Not really the time to rrai. Flatting is an option.

Considering that you'll only have a pot sized bet left if you go to the flop, I would push it all-in.
If you hit your hand on the flop you will get value from hands that would have called your AI pre-flop anyway, and you might get pushed out on the flop if you miss. With an AI you buy 2 more streets to hit it.

Considering that the only read I have on the player is that he plays 2NL
