JJ vs AJo

When JJ and AJo get all in before the flop, JJ wins 69.4% of the time and AJo takes 30.6%. Broken down, JJ wins outright 68.5%, chops 1.7% and loses 29.8% — a margin of 38.8 points. Pair against one overcard — roughly 70/30 in the pair's favour.

The same matchup shifts depending on how the suits overlap. With one shared suit the number is 69.2% (for example Js Jh against As Jd); with no shared suit it is 69.7% (Js Jh against Ad Jc). That is a spread of 0.44 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 54.4%, AJo 26.3%, random 19.4%. JJ gives up 15 points and AJo gives up 4.4, 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 AJo is worth 63.6% (rank 15). The gap between them in the ranking is only 13.9 points, yet head to head the gap is 38.8 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 69 pots, splits about 2, and loses the remaining 30. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% 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, 30.6% is the break-even point for calling an all-in at 2.27:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 30.6% of the pot you are playing for. JJ holds the other 69.4% 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 AJo really does hold exactly AJo; against the wider range a player would actually get all in with, JJ's 69.4% moves.
