Win, tie and loss for JJ
When JJ and AKo get all in before the flop, JJ wins 56.8% of the time and AKo takes 43.2%. Broken down, JJ wins outright 56.6%, chops 0.4% and loses 43.0% — a margin of 13.6 points. Pair against two overcards — the classic coinflip, with the pair a shade ahead.
The same matchup shifts depending on how the suits overlap. With both suits shared the number is 56.4% (for example Js Jh against As Kh); with no shared suit it is 57.1% (Js Jh against Ad Kc). That is a spread of 0.75 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 JJ 47.4%, AKo 37.2%, random 15.4%. JJ gives up 9.4 points and AKo gives up 6, 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, JJ is worth 77.5% against a random hand (rank 4 of 169) and AKo is worth 65.4% (rank 12). The gap between them in the ranking is only 12.1 points, yet head to head the gap is 13.6 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, JJ scoops roughly 57 pots, splits about one, and loses the remaining 43. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% 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, 43.2% is the break-even point for calling an all-in at 1.31:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 43.2% of the pot you are playing for. JJ holds the other 56.8% 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 AKo really does hold exactly AKo; against the wider range a player would actually get all in with, JJ's 56.8% moves. Use the individual pages for JJ and AKo to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.
