Win, tie and loss for JJ
When JJ and 72o get all in before the flop, JJ wins 88.2% of the time and 72o takes 11.8%. Broken down, JJ wins outright 87.9%, chops 0.4% and loses 11.6% — a margin of 76.3 points. Overpair against two undercards — about 80/20 for the pair.
The same matchup shifts depending on how the suits overlap. With no shared suit the number is 87.4% (for example Js Jh against 7d 2c); with both suits shared it is 89.0% (Js Jh against 7s 2h). That is a spread of 1.58 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 68.7%, 72o 10.2%, random 21.0%. JJ gives up 19.4 points and 72o gives up 1.6, 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 72o is worth 34.4% (rank 165). The gap between them in the ranking is only 43.1 points, yet head to head the gap is 76.3 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, JJ scoops roughly 88 pots, splits about one, and loses the remaining 12. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% and 72o to 5.5%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From 72o's side, 11.8% is the break-even point for calling an all-in at 7.47:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 11.8% of the pot you are playing for. JJ holds the other 88.2% 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 72o really does hold exactly 72o; against the wider range a player would actually get all in with, JJ's 88.2% moves. Use the individual pages for JJ and 72o to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.
