This is an enormous mistake. Since you are out of position you need to act aggressively pre-flop BECAUSE you will be out of position after the flop. If you had said "I was slow playing this because I had position" then maybe I can understand you trying to let your positional advantage work for you. I will sometimes (5-10% of time) do this when I have position because I need to vary my play, but generally not raising AK is a major mistake. Online I do not even bother trying to vary as much because you just don't meet people enough to have them get a solid read on how I play AK. And also, it is not that strong of a hand.......AK is simply a drawing hand...yes its the best drawing hand, but never forget that you will mostly need to improve in order to win a pot.

Key factor: When you have postion you can afford to let a hand play out slower.

When you will be out of position you want to end it early to nullify the positional disadvantage you will have

The same logic can apply when deciding on an all-in pre-flop (when faced with those decisions). I am much more inclined to make a push if I know I will be at a positional disadvantage than if I will have position on my opponent on the later streets.
