Against one random hand it wins 51.63% of showdowns and takes 53.25% of the pot. ## What this hand is Jack-nine offsuit. Before any board card is dealt its odds are identical to Jc9d, Jc9h, Jd9c, Jd9h, Jd9s, Jh9c, Jh9d, Jh9s, Js9c, Js9d, Js9h — suits are interchangeable pre-flop, so all 12 combinations in class J9o share the numbers below. That stops being true the moment the board has suits, which is what the paid record covers. ## Equity against random opponents | Opponents | Win % | Tie % | Pot equity % | | --------- | ----- | ----- | ------------ | | 1 | 51.63 | 3.24 | 53.25 | | 2 | 34.79 | 3.14 | 36.23 | | 3 | 26.45 | 2.96 | 27.78 | | 4 | 21.13 | 2.92 | 22.44 | | 5 | 17.52 | 2.81 | 18.79 | | 6 | 14.75 | 2.76 | 15.99 | | 7 | 12.70 | 2.76 | 13.95 | Monte Carlo, 400,000 trials per row, seed 1 — same seed, same digits. "Pot equity" counts outright wins plus a share of split pots, which is the number to compare against pot odds. ## Head-to-head, exact Against the opponent's whole hand class, not one chosen pair of cards: every combination of it you do not block, each enumerated over all 1,712,304 boards. No sampling. "Combos" is how many were averaged. | Against | Hero pot equity % | Hero win % | Split % | Combos | | ------- | ----------------- | ---------- | ------- | ------ | | AA | 16.64 | 16.46 | 0.35 | 6 | | KK | 15.44 | 15.25 | 0.38 | 6 | | QQ | 13.96 | 13.77 | 0.37 | 6 | | JJ | 11.07 | 9.95 | 2.25 | 3 | | TT | 28.91 | 28.70 | 0.41 | 6 | | 77 | 46.60 | 46.33 | 0.53 | 6 | | 22 | 50.37 | 49.64 | 1.46 | 6 | | AKs | 33.87 | 33.64 | 0.46 | 4 | | AKo | 35.55 | 35.33 | 0.44 | 12 | | AQs | 33.71 | 33.48 | 0.45 | 4 | | JTs | 27.09 | 21.88 | 10.41 | 3 | | 76s | 60.59 | 59.97 | 1.24 | 4 | Averaging matters here. Against a single representative the answer shifts with the suits — J♣T♣ takes 17.77% against Q♣Q♦ but 18.89% against Q♠Q♦, because the shared club both blocks a flush and removes cards. Averaged over the class the figure is the same whichever suits you hold, which is what makes it quotable. ## What this page cannot tell you Pre-flop equity is not a strategy. It ignores stack depth, bet sizing, and how your opponents actually play. The verdict above is a conventional opening chart, not solver output. Equity against a random hand is also not equity against a range: an opponent who raises has better than random cards, and this page does not model that. ## The full record Equity against modelled ranges (top 5/10/20/40%), position-by-position guidance, and the suit-specific analysis for this exact combination: GET https://poketpoker.com/api/hands/Jc9s $0.01 USDC (x402) ## Related - Suit-equivalents: [Jc9d](Jc9d.md) · [Jc9h](Jc9h.md) · [Jd9c](Jd9c.md) · [Jd9h](Jd9h.md) · [Jd9s](Jd9s.md) · [Jh9c](Jh9c.md) · [Jh9d](Jh9d.md) · [Jh9s](Jh9s.md) · [Js9c](Js9c.md) · [Js9d](Js9d.md) · [Js9h](Js9h.md) - All 1,326 hands: [index](index.md) - URL convention: `/hands/.md`, higher rank first, suits ordered c, d, h, s.
