Win, tie and loss for 99
When 99 and AJo get all in before the flop, 99 wins 55.4% of the time and AJo takes 44.6%. Broken down, 99 wins outright 55.3%, chops 0.4% and loses 44.4% — a margin of 10.9 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 both suits shared the number is 55.0% (for example 9s 9h against As Jh); with no shared suit it is 55.8% (9s 9h against Ad Jc). That is a spread of 0.73 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 99 44.2%, AJo 37.2%, random 18.6%. 99 gives up 11.2 points and AJo gives up 7.4, 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 AJo is worth 63.6% (rank 15). The gap between them in the ranking is only 8.6 points, yet head to head the gap is 10.9 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 55 pots, splits about one, and loses the remaining 44. Against eight random opponents rather than this one specific hand, 99 would be down to 17.2% and AJo to 16.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From AJo's side, 44.6% is the break-even point for calling an all-in at 1.24:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 44.6% of the pot you are playing for. 99 holds the other 55.4% 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 AJo really does hold exactly AJo; against the wider range a player would actually get all in with, 99's 55.4% moves.
