Win, tie and loss for KK
When KK and 44 get all in before the flop, KK wins 80.9% of the time and 44 takes 19.1%. Broken down, KK wins outright 80.7%, chops 0.5% and loses 18.9% — a margin of 61.8 points. Pair over pair — the higher pair is roughly an 80/20 favourite.
The same matchup shifts depending on how the suits overlap. With no shared suit the number is 80.2% (for example Ks Kh against 4d 4c); with both suits shared it is 81.7% (Ks Kh against 4s 4h). That is a spread of 1.51 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 KK 67.8%, 44 17.2%, random 15.0%. KK gives up 13.1 points and 44 gives up 2, 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, KK is worth 82.5% against a random hand (rank 2 of 169) and 44 is worth 57.0% (rank 48). The gap between them in the ranking is only 25.5 points, yet head to head the gap is 61.8 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, KK scoops roughly 81 pots, splits about one, and loses the remaining 19. Against eight random opponents rather than this one specific hand, KK would be down to 29.6% and 44 to 13.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From 44's side, 19.1% is the break-even point for calling an all-in at 4.24:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 19.1% of the pot you are playing for. KK holds the other 80.9% 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 44 really does hold exactly 44; against the wider range a player would actually get all in with, KK's 80.9% moves.
