equity

MathAliases: 胜率, 权益, equity

Equity is the expected percentage of the pot a hand or range wins against a specific opponent range. Equity is the core input to EV calculations.

Equity is the average percentage of the pot a current hand or range wins at immediate showdown against a specified opponent range.

Detailed Explanation

There are two types of equity to distinguish:

  • Raw equity: equity at immediate showdown, ignoring future actions
  • Realized equity: equity actually realized after accounting for position, betting, folds, and other dynamic factors

Example: 88 vs an opponent's wide cbet range may have 55% raw equity, but if 88 is OOP and struggles against turn barrels, its realized equity might be only 45%.

Factors that affect realized equity:

  • Position (IP usually realizes more)
  • SPR (stack-to-pot ratio)
  • Opponent's aggression frequency
  • Your bluff-catching ability

Common Use Cases

  • Drawing decisions: pot odds vs equity
  • Flop sizing: range-equity distribution determines bet frequency and size
  • Range construction: high-equity hands as value, low-equity hands with good blockers as bluffs

Common Mistakes

  • Treating raw equity as the decision criterion: in practice, almost always adjust to realized equity
  • Ignoring shifts in opponent's range: loose vs tight changes the same hand's equity by 10%+
