Against one random hand it wins 52.26% of showdowns and takes 53.97% of the pot. ## What this hand is Jack-eight of diamonds. Before any board card is dealt its odds are identical to Jc8c, Jh8h, Js8s — suits are interchangeable pre-flop, so all 4 combinations in class J8s 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 | 52.26 | 3.42 | 53.97 | | 2 | 35.90 | 3.23 | 37.38 | | 3 | 27.75 | 2.99 | 29.10 | | 4 | 22.68 | 2.86 | 23.96 | | 5 | 19.28 | 2.78 | 20.53 | | 6 | 16.78 | 2.73 | 18.01 | | 7 | 14.88 | 2.63 | 16.06 | 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 | 19.37 | 19.19 | 0.36 | 6 | | KK | 19.06 | 18.86 | 0.39 | 6 | | QQ | 17.93 | 17.74 | 0.39 | 6 | | JJ | 14.75 | 13.62 | 2.25 | 3 | | TT | 32.09 | 31.88 | 0.42 | 6 | | 77 | 47.94 | 47.66 | 0.57 | 6 | | 22 | 51.88 | 51.15 | 1.46 | 6 | | AKs | 35.93 | 35.69 | 0.49 | 4 | | AKo | 38.42 | 38.19 | 0.45 | 12 | | AQs | 35.77 | 35.52 | 0.49 | 4 | | JTs | 30.91 | 26.04 | 9.73 | 3 | | 76s | 62.72 | 62.09 | 1.27 | 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/Jd8d $0.01 USDC (x402) ## Related - Suit-equivalents: [Jc8c](Jc8c.md) · [Jh8h](Jh8h.md) · [Js8s](Js8s.md) - All 1,326 hands: [index](index.md) - URL convention: `/hands/.md`, higher rank first, suits ordered c, d, h, s.
