Win, tie and loss for KK
When KK and AJo get all in before the flop, KK wins 71.3% of the time and AJo takes 28.7%. Broken down, KK wins outright 71.1%, chops 0.4% and loses 28.5% — a margin of 42.7 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 71.2% (for example Ks Kh against Ad Jc); with both suits shared it is 71.4% (Ks Kh against As Jh). That is a spread of 0.23 points across the 72 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 60.8%, AJo 25.0%, random 14.2%. KK gives up 10.5 points and AJo gives up 3.7, 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 AJo is worth 63.6% (rank 15). The gap between them in the ranking is only 18.9 points, yet head to head the gap is 42.7 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 71 pots, splits about one, and loses the remaining 28. Against eight random opponents rather than this one specific hand, KK would be down to 29.6% and AJo to 16.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From AJo's side, 28.7% is the break-even point for calling an all-in at 2.48:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 28.7% of the pot you are playing for. KK holds the other 71.3% of that same pot.
Two caveats keep this figure honest. First, it is showdown equity across all 72 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 AJo really does hold exactly AJo; against the wider range a player would actually get all in with, KK's 71.3% moves.
