Methodology
  • Ranges: the 6-max 100bb preflop solve. Each side's range is its solver strategy weighted by its own reach: the product of its prior action frequencies (a hand the opener never opens can't appear in its 3-bet-pot calling range). RFI pot = opener's raise vs the later seat's call; 3-bet pot = the later seat's 3-bet vs the opener's call; 4-bet pot = the opener's 4-bet vs the later seat's call (only where the big blind flats - elsewhere the line is 5-bet or fold).
  • Equity: Monte-Carlo over 50,000 frequency-weighted combo pairs per flop, each resolved on one random turn-river runout with the same Omaha hand rankings as the equity calculator. The twelve curated textures are precomputed for every matchup; custom flops run the same computation live in your browser.
  • Flopped nuts = the share of a range that flops the board's nut class, which depends only on flop texture:
    • Monotone (three of one suit): the nut flush. Where the ranks also allow a straight flush, straight flushes count in the same bucket.
    • Paired: a full house or quads - every boat counts, not just the top one.
    • Unpaired, straight possible (three ranks inside a five-rank run): the nut straight.
    • Unpaired, no straight, no flush: top set.
    One class per board, so the share is small on most textures. Each combo is classified exactly by Omaha two-plus-three rules and weighted by its range frequency, no sampling. Expanding a flop tags the nut class in the breakdown and splits every made class into its nut and non-nut versions, so you can read how much of a range's flushes, straights, or sets are the nut version rather than a dominated one.
