Theory preview
- Equity Realization (EqR)
- Equity realization is how much of your theoretical equity you actually capture in practice. A hand with 40% equity doesn't always win 40% of the pot — it might fold to pressure and realize less, or it might be in position and realize more by seeing free cards.
