KK vs AKo

When KK and AKo get all in before the flop, KK wins 69.8% of the time and AKo takes 30.2%. Broken down, KK wins outright 69.4%, chops 0.8% and loses 29.8% — a margin of 39.6 points. Pair against one overcard — roughly 70/30 in the pair's favour.

The same matchup shifts depending on how the suits overlap. With one shared suit the number is 69.7% (for example Ks Kh against As Kd); with no shared suit it is 70.0% (Ks Kh against Ad Kc). That is a spread of 0.24 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 KK 58.3%, AKo 26.1%, random 15.5%. KK gives up 11.5 points and AKo gives up 4.1, 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, KK is worth 82.5% against a random hand (rank 2 of 169) and AKo is worth 65.4% (rank 12). The gap between them in the ranking is only 17.1 points, yet head to head the gap is 39.6 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, KK scoops roughly 69 pots, splits about one, and loses the remaining 30. Against eight random opponents rather than this one specific hand, KK would be down to 29.6% 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, 30.2% is the break-even point for calling an all-in at 2.31:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 30.2% of the pot you are playing for. KK holds the other 69.8% 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, KK's 69.8% moves.
