AK is the kind of hand where if you flop top pair, its just like aces. Early position i make a 3x raise, if there are many callers then i just hope to get a lucky flop, if i miss(meaning no draw at all) and someone makes a good bet, i lay it down easily. If it hits and I'm first to act, i change it up sometimes. Sometimes i'll bet it, sometimes i'll check to act weak hoping someone else paired something big then i raise them.
Mid-late position I make a 4x-5x raise depending on how loose the players are, I try to narrow it down to 2 players because I find it very easily to know if my ace high is good when i miss the flop. If you know how to outplay other ppl on the flop then thats a perfect strategy for you, If you dont just stick on the 3x-4x raise.
When their's an all in bet and no one else called it and I have AK, of course i'll call, It'll either be a coin flip (with me being 43% to win) or I'll have the other person dominated
AK is actually a very easy hand to play in my opinion.
