Win, tie and loss for JJ
When JJ and 88 get all in before the flop, JJ wins 81.2% of the time and 88 takes 18.8%. Broken down, JJ wins outright 81.0%, chops 0.4% and loses 18.6% — a margin of 62.3 points. Pair over pair — the higher pair is roughly an 80/20 favourite.
The same matchup shifts depending on how the suits overlap. With no shared suit the number is 80.3% (for example Js Jh against 8d 8c); with both suits shared it is 81.8% (Js Jh against 8s 8h). That is a spread of 1.44 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 JJ 63.5%, 88 17.2%, random 19.3%. JJ gives up 17.7 points and 88 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 88 is worth 69.2% (rank 7). The gap between them in the ranking is only 8.3 points, yet head to head the gap is 62.3 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 81 pots, splits about one, and loses the remaining 19. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% and 88 to 15.9%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From 88's side, 18.8% is the break-even point for calling an all-in at 4.32:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 18.8% of the pot you are playing for. JJ holds the other 81.2% 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 88 really does hold exactly 88; against the wider range a player would actually get all in with, JJ's 81.2% moves.
