AKo vs 65s

When AKo and 65s get all in before the flop, AKo wins 58.5% of the time and 65s takes 41.5%. Broken down, AKo wins outright 58.3%, chops 0.5% and loses 41.2% — a margin of 17.1 points. Two unpaired hands with no shared rank — the higher cards usually run 60–65%.

The same matchup shifts depending on how the suits overlap. With no shared suit the number is 58.0% (for example As Kh against 6d 5d); with one shared suit it is 59.1% (As Kh against 6s 5s). That is a spread of 1.09 points across the 48 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 AKo 45.2%, 65s 31.6%, random 23.3%. AKo gives up 13.4 points and 65s gives up 9.9, 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, AKo is worth 65.4% against a random hand (rank 12 of 169) and 65s is worth 43.0% (rank 128). The gap between them in the ranking is only 22.4 points, yet head to head the gap is 17.1 points, which is roughly what the ranking table predicts.

Framed as a run of one hundred identical all-ins, AKo scoops roughly 58 pots, splits about one, and loses the remaining 41. Against eight random opponents rather than this one specific hand, AKo would be down to 19.1% and 65s to 12.6%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From 65s's side, 41.5% is the break-even point for calling an all-in at 1.41:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 41.5% of the pot you are playing for. AKo holds the other 58.5% of that same pot.

Two caveats keep this figure honest. First, it is showdown equity across all 48 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 65s really does hold exactly 65s; against the wider range a player would actually get all in with, AKo's 58.5% moves. Use the individual pages for AKo and 65s to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.
