AKs vs AJs

When AKs and AJs get all in before the flop, AKs wins 71.0% of the time and AJs takes 29.0%. Broken down, AKs wins outright 68.9%, chops 4.2% and loses 26.9% — a margin of 42.1 points. Domination — a shared rank turns this into a kicker fight, and kicker fights are lopsided.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 71.0% (for example As Ks against Ah Jh); with no shared suit it is 71.0% (As Ks against Ah Jh). 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 AKs 49.0%, AJs 25.1%, random 26.0%. AKs gives up 22.1 points and AJs gives up 3.9, 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, AKs is worth 67.2% against a random hand (rank 8 of 169) and AJs is worth 65.4% (rank 11). The gap between them in the ranking is only 1.8 points, yet head to head the gap is 42.1 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, AKs scoops roughly 69 pots, splits about 4, and loses the remaining 27. Against eight random opponents rather than this one specific hand, AKs would be down to 22.4% and AJs to 20.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From AJs's side, 29.0% is the break-even point for calling an all-in at 2.45:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 29.0% of the pot you are playing for. AKs holds the other 71.0% 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 AJs really does hold exactly AJs; against the wider range a player would actually get all in with, AKs's 71.0% moves.
