Win, tie and loss for JJ

Win 81.3%Lose 16.7%

When JJ and JTs get all in before the flop, JJ wins 82.3% of the time and JTs takes 17.7%. Broken down, JJ wins outright 81.3%, chops 2.0% and loses 16.7% — a margin of 64.6 points. Pair against one overcard — roughly 70/30 in the pair's favour.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 82.3% (for example Js Jh against Jd Td); with no shared suit it is 82.3% (Js Jh against Jd Td). That is a spread of 0 points across the 12 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 62.6%, JTs 17.0%, random 20.4%. JJ gives up 19.7 points and JTs gives up 0.7, 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, JJ is worth 77.5% against a random hand (rank 4 of 169) and JTs is worth 57.5% (rank 46). The gap between them in the ranking is only 20 points, yet head to head the gap is 64.6 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 81 pots, splits about 2, and loses the remaining 17. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% and JTs to 18.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From JTs's side, 17.7% is the break-even point for calling an all-in at 4.65:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 17.7% of the pot you are playing for. JJ holds the other 82.3% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 12 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 JTs really does hold exactly JTs; against the wider range a player would actually get all in with, JJ's 82.3% moves.
