KJs vs KQo

When KJs and KQo get all in before the flop, KJs wins 30.4% of the time and KQo takes 69.6%. Broken down, KJs wins outright 27.8%, chops 5.3% and loses 66.9% — a margin of -39.2 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 one shared suit the number is 29.6% (for example Ks Js against Kh Qs); with no shared suit it is 30.8% (Ks Js against Kh Qd). That is a spread of 1.24 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 KJs 26.0%, KQo 42.6%, random 31.4%. KJs gives up 4.5 points and KQo gives up 27, so the underdog loses more than the favourite does. Extra players always eat into the leader's share faster than into anyone else's.

Taken on their own, KJs is worth 62.5% against a random hand (rank 20 of 169) and KQo is worth 61.5% (rank 23). The gap between them in the ranking is only 1 points, yet head to head the gap is 39.2 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, KJs scoops roughly 28 pots, splits about 5, and loses the remaining 67. Against eight random opponents rather than this one specific hand, KJs would be down to 19.0% and KQo to 16.7%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From KQo's side, 69.6% is the break-even point for calling an all-in at 0.44:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 69.6% of the pot you are playing for. KJs holds the other 30.4% 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 KQo really does hold exactly KQo; against the wider range a player would actually get all in with, KJs's 30.4% moves. Use the individual pages for KJs and KQo to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.

When the three flop cards are out, KJs is ahead 16.6% of the time and KQo 83.4%, and the two hands are never level on the flop. "Ahead" means the better best-five-card hand from the cards showing plus the two hole cards; draws are not counted.

When KJs leads on the flop, KQo comes back on the turn and river 21.5% of the time. When KQo leads on the flop, KJs turns it around 17.7% of the time. The hand in front holds on to win 76.3% of the time from the flop and 84.8% from the turn (level spots left out).

With the turn out, KJs leads 22.0% and KQo 76.6%. Counted exhaustively, KJs finishes with 30.25% equity (the 30.4% at the top of the page is a 200,000-hand simulation).
