River Bluff-Catching Framework: Which Hands Should Call
Short Answer
Good river bluff catchers block opponent value hands while not blocking missed natural bluffs. The larger the bet, the more bluff frequency you need. Against chronic under-bluffers, you should defend below theory.
Start With Bet Size
On the river, there is no future equity to realize. Calling depends on current price and the opponent's range. Large bets require more bluffs. Small bets require wider defense.
Choosing Bluff Catchers
The best bluff catcher is not always the hand with the highest absolute strength. It is the hand with the best combo effect: blocking strong value while keeping missed flush, straight, or air bluffs available.
Opponent Type
Some hands are theory calls, but folding is better if the pool under-bluffs river. Against over-polarized and over-bluffing opponents, defense can expand.
Decision Steps
- Estimate required win rate from bet size.
- List opponent value and natural bluffs.
- Check whether your hand blocks value or bluffs.
- Adjust to real opponent bluff frequency.
