How to use

Pick preflop, flop or turn above and tap any situation to see each hand's equity, its win and split shares, and the key takeaway. The URL of the detail panel can be shared as is. “Open in equity calculator” loads the hands and board into the equity calculator and runs it, so you can swap cards, add players or switch to ranges.

Assumptions & limits

Every equity comes from our own equity engine enumerating every possible runout: no simulation and no hand-typed numbers. Preflop that is 1,712,304 boards (1,370,754 three-way), 990 on the flop and 44 on the turn. Equity = outright wins + the split share ÷ the number of players sharing (a split pot counts for half); the split share is the share of runouts where two or more hands tie. The situations assume both players are all in, with no dead cards from other players and no later betting. They are fixed hands, not range versus range.
