Against one random hand it wins 38.53% of showdowns and takes 41.43% of the pot. ## What this hand is Five-four of spades. Before any board card is dealt its odds are identical to 5c4c, 5d4d, 5h4h — suits are interchangeable pre-flop, so all 4 combinations in class 54s 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 | 38.53 | 5.80 | 41.43 | | 2 | 27.32 | 3.50 | 28.85 | | 3 | 21.38 | 2.99 | 22.69 | | 4 | 17.76 | 2.64 | 18.93 | | 5 | 15.35 | 2.43 | 16.42 | | 6 | 13.72 | 2.30 | 14.74 | | 7 | 12.50 | 2.28 | 13.51 | 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 | 21.09 | 20.87 | 0.45 | 6 | | KK | 22.52 | 22.29 | 0.46 | 6 | | QQ | 22.51 | 22.29 | 0.45 | 6 | | JJ | 22.52 | 22.29 | 0.46 | 6 | | TT | 22.14 | 21.88 | 0.53 | 6 | | 77 | 20.15 | 19.48 | 1.35 | 6 | | 22 | 51.35 | 49.60 | 3.49 | 6 | | AKs | 38.66 | 38.38 | 0.56 | 4 | | AKo | 41.24 | 40.98 | 0.52 | 12 | | AQs | 38.58 | 38.30 | 0.55 | 4 | | JTs | 37.23 | 36.64 | 1.18 | 4 | | 76s | 37.96 | 34.50 | 6.93 | 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/5s4s $0.01 USDC (x402) ## Related - Suit-equivalents: [5c4c](5c4c.md) · [5d4d](5d4d.md) · [5h4h](5h4h.md) - All 1,326 hands: [index](index.md) - URL convention: `/hands/.md`, higher rank first, suits ordered c, d, h, s.
