Call. If he has AA then that's unlucky. If he has KK you are a bit behind but still have the overcard. Anything else, it's a coin flip or you are well ahead.
The problem with AK is that you are very rarely "well ahead"
Even if the guy has random crap such as T8os you are only about a 65%-35% shot.
In a sitngo I fold every hand for the first 3 levels unless it's AA KK or QQMy god, and ppl give you action when you get a hand. What stakes?
p.s, what SnG affords you that luxury?
