Methodology
  • Ranges: the 6-max 100bb v3 solve's complete reach ranges at clean, heads-up flop-entry nodes. Each range includes the frequency of that player's prior preflop actions. 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. The source's exact 45 node paths and range hashes are recorded with this study's data.
  • 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 each board-compatible range whose four-card hand cannot be beaten by any legal opponent holding on this flop. We compare the hand's best two-card hole pair with every opponent pair disjoint from all four hole cards and the board; ties count as nuts. This uses no opponent range. The other class rows are broader; for example, “Full house or quads” includes boats beaten by higher boats and quads. Class shares are exact and independently normalized after board removal. Equity samples legal, card-compatible pairs from both ranges, so its population is different.
