AA vs AKo

When AA and AKo get all in before the flop, AA wins 93.2% of the time and AKo takes 6.8%. Broken down, AA wins outright 92.5%, chops 1.3% and loses 6.2% — a margin of 86.3 points. Pair against one overcard — roughly 70/30 in the pair's favour.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 92.7% (for example As Ah against Ad Kc); with one shared suit it is 93.4% (As Ah against Ad Ks). That is a spread of 0.76 points across the 36 distinct card combinations, and it comes almost entirely from whether the two hands are fighting over the same flush.

Add a third player holding a random hand and the split becomes AA 78.4%, AKo 6.5%, random 15.0%. AA gives up 14.7 points and AKo gives up 0.3, so the favourite loses more than the underdog does. Extra players always eat into the leader's share faster than into anyone else's.

Taken on their own, AA is worth 85.2% against a random hand (rank 1 of 169) and AKo is worth 65.4% (rank 12). The gap between them in the ranking is only 19.8 points, yet head to head the gap is 86.3 points — a reminder that a ranking table and a direct matchup are two different questions.

Framed as a run of one hundred identical all-ins, AA scoops roughly 93 pots, splits about 1, and loses the remaining 6. Against eight random opponents rather than this one specific hand, AA would be down to 34.5% and AKo to 19.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From AKo's side, 6.8% is the break-even point for calling an all-in at 13.71:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 6.8% of the pot you are playing for. AA holds the other 93.2% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 36 card combinations with five board cards still to come — there is no fold equity in it, so the value of shoving in practice is usually higher than the raw percentage suggests. Second, it assumes AKo really does hold exactly AKo; against the wider range a player would actually get all in with, AA's 93.2% moves.
