IMO AK , bet stong oop , raise the min 2.5x in position , if you miss the flop cbet in position one maybe two or even 3 turns dependingly on the board and if there are draws or not ,if you see a lot of action before you (raises,reraises )-fold , oop be more carefull cbet with one opponent (how many times depends on the texture of the board ,if it helps you with draws, like HU etc), be carefull with more opponents see the board and the villlains and decide accordingly ,and especially early levels , when you're low stacked and have AK under 20BB it's good to double up with all in preflop . There are a lot of stategies of how to play AK according to how many players on table, position, blinds leves , bets , board texture , the villains etc
