Win, tie and loss for 99
When 99 and AKs get all in before the flop, 99 wins 52.6% of the time and AKs takes 47.4%. Broken down, 99 wins outright 52.4%, chops 0.4% and loses 47.1% — a margin of 5.3 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 52.5% (for example 9s 9h against Ad Kd); with one shared suit it is 52.7% (9s 9h against As Ks). That is a spread of 0.16 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 99 41.8%, AKs 41.5%, random 16.7%. 99 gives up 10.9 points and AKs gives up 5.8, 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, 99 is worth 72.2% against a random hand (rank 6 of 169) and AKs is worth 67.2% (rank 8). The gap between them in the ranking is only 5 points, yet head to head the gap is 5.3 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, 99 scoops roughly 52 pots, splits about one, and loses the remaining 47. Against eight random opponents rather than this one specific hand, 99 would be down to 17.2% and AKs to 22.4%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From AKs's side, 47.4% is the break-even point for calling an all-in at 1.11:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 47.4% of the pot you are playing for. 99 holds the other 52.6% 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 AKs really does hold exactly AKs; against the wider range a player would actually get all in with, 99's 52.6% moves.
