Win, tie and loss for AJo
When AJo and 66 get all in before the flop, AJo wins 45.8% of the time and 66 takes 54.2%. Broken down, AJo wins outright 45.6%, chops 0.4% and loses 54.0% — a margin of -8.4 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 45.3% (for example As Jh against 6d 6c); with both suits shared it is 46.3% (As Jh against 6s 6h). That is a spread of 0.98 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 AJo 38.1%, 66 39.6%, random 22.3%. AJo gives up 7.7 points and 66 gives up 14.6, 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, AJo is worth 63.6% against a random hand (rank 15 of 169) and 66 is worth 63.3% (rank 17). The gap between them in the ranking is only 0.3 points, yet head to head the gap is 8.4 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, AJo scoops roughly 46 pots, splits about one, and loses the remaining 54. Against eight random opponents rather than this one specific hand, AJo would be down to 16.1% and 66 to 13.7%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.
From 66's side, 54.2% is the break-even point for calling an all-in at 0.85:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 54.2% of the pot you are playing for. AJo holds the other 45.8% 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 66 really does hold exactly 66; against the wider range a player would actually get all in with, AJo's 45.8% moves.
