SB River C-Bet

Definition and Background

SB [River C-Bet] refers to a continuation [Bet] made on the river by a player who entered the flop from the [Small Blind] position.

Characteristics and Strategy

• Positional Disadvantage: The small blind has the worst postflop position (except the big blind), acting last only preflop. On the river, all actions occur after the opponent. Therefore, an SB [River C-Bet] requires stronger hand strength, as the opponent has the final say.
• Range Representation: The small blind typically enters the pot with a raise or call preflop, resulting in a tighter range. After a flop continuation bet, a turn continuation bet usually represents a strong hand, and a river bet further polarizes the range, typically representing either value or pure bluffs.
• Sizing and Frequency: Due to positional disadvantage, SB c-bets on the river with lower frequency than in position. [Bet sizing] is relative to pot size, commonly 50%-75% pot.
• Opponent Adjustments: Experienced opponents may raise on the river against the SB's [C-Bet], forcing tough decisions. Thus, the SB must carefully select bluffing opportunities, often using blockers (e.g., holding cards that block the opponent's flush or straight) to reduce the risk of being caught.

Example Scenario

Preflop: Small blind raises, big blind calls. Flop: K♥7♦2♠, small blind bets ([C-Bet]), big blind calls. Turn: J♣, small blind checks, big blind checks. River: 4♠, small blind bets (River [continuation bet]). This bet represents the small blind possibly holding Kx or a [bluff], and the big blind may fold middle pairs.

Notes

• Avoid excessive bluffing on the river, especially after the opponent has called both flop and turn.
• Consider the opponent's range and pot odds to ensure value bets get called by worse hands often enough, and bluff bets have sufficient fold equity.
• Use blockers to select bluff hands; for example, holding A♠ blocks the flush, increasing success rate.
