Win, tie and loss for KQo

Win 46.7%Lose 52.7%

When KQo and 55 get all in before the flop, KQo wins 47.0% of the time and 55 takes 53.0%. Broken down, KQo wins outright 46.7%, chops 0.6% and loses 52.7% — a margin of -6 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 46.6% (for example Ks Qh against 5d 5c); with both suits shared it is 47.5% (Ks Qh against 5s 5h). That is a spread of 0.94 points across the 72 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 KQo 39.4%, 55 37.4%, random 23.3%. KQo gives up 7.6 points and 55 gives up 15.6, 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, KQo is worth 61.5% against a random hand (rank 23 of 169) and 55 is worth 60.3% (rank 27). The gap between them in the ranking is only 1.2 points, yet head to head the gap is 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, KQo scoops roughly 47 pots, splits about one, and loses the remaining 53. Against eight random opponents rather than this one specific hand, KQo would be down to 16.7% and 55 to 13.2%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From 55's side, 53.0% is the break-even point for calling an all-in at 0.89:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 53.0% of the pot you are playing for. KQo holds the other 47.0% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 72 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 55 really does hold exactly 55; against the wider range a player would actually get all in with, KQo's 47.0% moves.
