JJ vs AQs

When JJ and AQs get all in before the flop, JJ wins 54.2% of the time and AQs takes 45.8%. Broken down, JJ wins outright 54.0%, chops 0.4% and loses 45.6% — a margin of 8.3 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 no shared suit the number is 54.1% (for example Js Jh against Ad Qd); with one shared suit it is 54.3% (Js Jh against As Qs). That is a spread of 0.19 points across the 24 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 45.1%, AQs 39.5%, random 15.4%. JJ gives up 9.1 points and AQs gives up 6.4, 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 AQs is worth 66.2% (rank 10). The gap between them in the ranking is only 11.3 points, yet head to head the gap is 8.3 points, which is roughly what the ranking table predicts.

Framed as a run of one hundred identical all-ins, JJ scoops roughly 54 pots, splits about one, and loses the remaining 46. Against eight random opponents rather than this one specific hand, JJ would be down to 21.7% and AQs to 21.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From AQs's side, 45.8% is the break-even point for calling an all-in at 1.18:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 45.8% of the pot you are playing for. JJ holds the other 54.2% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 24 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 AQs really does hold exactly AQs; against the wider range a player would actually get all in with, JJ's 54.2% moves.
