AKo is neither all in or fold. Because this hand gives you 16,29% chances to win with the potential of this particulars cards. So the probability wold be Under The Gun, the first person to speak on the poker, UTG = 5,178% positive, assuming there are 9 players on the table. Tell me how much do you pay to see that hand, knowning this simple math . In games like fixed limited bets...The hange of this hand is, if Pot Unraised = ReRaise, if Pot Raised = ReRaise, in whatever position, early, middle or late... On that in mind this argument guides to one point of view that is diferent than all win or fold, but i hope will help you overcome possible bad beats.
AK is very a good hand to play aggressive both pre and post flop. It's one of the ultimate drawing hands in the game. I am willing to get in preflop with Ace king against some of the more aggressive opponents because we have a lot more fold equity and even if called we're not in bad condition.
Ace King versus more "nittier" rock tight opponents though can be a scary hand to play with because you may be running into the top of their range more often for example potentially ranges of QQ+. Kxx FLOP versus someone that raises only AA/KK is not going to be a fun runout for you.
So to answer the question depending on how aggressive someone is it could be a slam dunk call or a snap fold.
I was playing 1/2 cash game 9 player full ring at a local casino. I'm in small blind with AKs (my stack $220ish).
MP3 (stack 800ish) raises to $15 (pretty standard for that place), BTN calls, I call...
BB reraises to $60 (stack $700ish), MP3 calls, BTN folds...
At that point i thought im against AA or other strong pair with at least another strong pair....I folded.
FLOP: A6K go figure lol
Was that the right play? I think it was. I would lose a lot of my stack if I missed, and I knew that MP3 is a good player so if he called then I'm most certainly behind preflop. the guy in BB was showing winners on those type of raises before too so he was running pretty good too.
Most old skool players will tell you to not over-rate AKo. It is a nightmare OOP in a cash game. I do tend to shove it, but the right move is probably to try and see a flop cheaper or fold when it comes to wanting an edge.
But a good tip is to play it like KQ, as opposed to playing it like AA.
