AKo vs JTs

When AKo and JTs get all in before the flop, AKo wins 59.5% of the time and JTs takes 40.5%. Broken down, AKo wins outright 59.2%, chops 0.5% and loses 40.3% — a margin of 18.9 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 59.0% (for example As Kh against Jd Td); with one shared suit it is 60.0% (As Kh against Js Ts). That is a spread of 1.03 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 44.2%, JTs 34.5%, random 21.3%. AKo gives up 15.3 points and JTs gives up 6, 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 JTs is worth 57.5% (rank 46). The gap between them in the ranking is only 7.9 points, yet head to head the gap is 18.9 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, AKo scoops roughly 59 pots, splits about one, and loses the remaining 40. Against eight random opponents rather than this one specific hand, AKo would be down to 19.1% and JTs to 18.1%, so the shape of this particular confrontation matters far more than either hand's standing in the overall ranking.

From JTs's side, 40.5% is the break-even point for calling an all-in at 1.47:1 pot odds. Put another way, the call is profitable as long as the amount you have to put in is less than 40.5% of the pot you are playing for. AKo holds the other 59.5% 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 JTs really does hold exactly JTs; against the wider range a player would actually get all in with, AKo's 59.5% moves. Use the individual pages for AKo and JTs to see how each of them fares against all 168 other holdings before treating this single pairing as the whole picture.

When the three flop cards are out, AKo is ahead 72.6% of the time and JTs 27.4%, and the two hands are never level on the flop. "Ahead" means the better best-five-card hand from the cards showing plus the two hole cards; draws are not counted.

When AKo leads on the flop, JTs comes back on the turn and river 26.4% of the time. When JTs leads on the flop, AKo turns it around 22.8% of the time. The hand in front holds on to win 74.1% of the time from the flop and 84.5% from the turn (level spots left out).

With the turn out, AKo leads 65.8% and JTs 34.2%. Counted exhaustively, AKo finishes with 59.49% equity (the 59.5% at the top of the page is a 200,000-hand simulation).
