Win, tie and loss for 88

Win 52.6%Lose 47.0%

When 88 and AJs get all in before the flop, 88 wins 52.8% of the time and AJs takes 47.2%. Broken down, 88 wins outright 52.6%, chops 0.4% and loses 47.0% — a margin of 5.6 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 52.7% (for example 8s 8h against Ad Jd); with one shared suit it is 53.0% (8s 8h against As Js). That is a spread of 0.29 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 88 41.0%, AJs 40.0%, random 19.0%. 88 gives up 11.8 points and AJs gives up 7.2, 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, 88 is worth 69.2% against a random hand (rank 7 of 169) and AJs is worth 65.4% (rank 11). The gap between them in the ranking is only 3.8 points, yet head to head the gap is 5.6 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, 88 scoops roughly 53 pots, splits about one, and loses the remaining 47. Against eight random opponents rather than this one specific hand, 88 would be down to 15.9% and AJs to 20.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From AJs's side, 47.2% is the break-even point for calling an all-in at 1.12:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 47.2% of the pot you are playing for. 88 holds the other 52.8% 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 AJs really does hold exactly AJs; against the wider range a player would actually get all in with, 88's 52.8% moves.
