Robust vs Non-Robust Equity: Why Some Hands Can Raise

Short Answer
Robust equity remains valuable even after the opponent's continuing range gets stronger. Strong draws, nut draws, and strong made hands are more robust. Weak pairs and fragile bluff catchers are often non-robust.
Why It Matters
Betting and raising fold out weak hands. That makes the opponent's continuing range stronger. If your hand still performs well against that stronger range, aggression can make sense. If your value mostly comes from beating weak folds, aggression may reduce EV.
Common Examples
Flush draws and open-ended straight draws can keep equity when called. Medium pairs on wet boards often lose value once villain continues with stronger pairs and draws.
Decision Steps
- List the hands villain folds when you bet.
- Study how your hand performs against the continuing range.
- Use more pressure with robust equity.
- Use checks, small bets, or position with non-robust equity.
