Equity explained: wins, ties, and ranges

Equity is your expected share of the pot if the remaining cards are dealt many times under a defined model. Against one opponent, a win contributes the full pot, a two-way tie contributes half, and a loss contributes nothing. This makes equity different from win probability whenever ties are possible.

A worked example

Imagine a simulation reports 44% wins, 4% two-way ties, and 52% losses. Win probability is 44%, but pot equity is 46% because half of the tied outcomes belong to each player: 44 + (4 ÷ 2). The percentages should sum to 100%, allowing for small rounding differences.

Equity is always “against something”

A hand has no single universal equity value. It has equity against a particular hand or distribution of hands. Pocket queens performs differently against a uniformly random holding than against a narrow range containing mostly aces, kings, and ace-king. When PokerOddz does not know opponent cards, it samples possible unknown cards; that is a neutral study baseline, not a claim about a real person’s likely range.

Multiway pots

Additional opponents create more ways for at least one hand to improve. Equity usually falls as opponents are added, but it does not necessarily divide evenly because different hand types interact with the board in different ways. In a tie involving three players, each receives one-third of that tied outcome rather than one-half.

Equity changes with information

Pre-flop estimates average across five future board cards. A flop estimate conditions on three known community cards, and a turn estimate conditions on four. A dramatic change is not a contradiction: it reflects a smaller, more specific set of possible outcomes. Results should always be saved with the exact cards, number of players, and assumptions that produced them.
