River C-Bet from BB

Background

In No-Limit Texas Hold'em, the Big Blind (BB) is the last to act preflop and often needs to defend their blind. When BB calls a raise from a position (such as the Button or Small Blind) preflop, on the flop they may choose to lead bet or check-raise, but if they become the preflop aggressor (e.g., they 3-bet and the opponent calls), then on the flop as the preflop raiser they will usually make a continuation bet (C-Bet).

Meaning

“River C-Bet from BB” specifically refers to a continuation bet made by the Big Blind player on the river. At this point, BB may have bet or checked on the flop and turn, but on the river they bet again, attempting to get the opponent to fold or to extract value.

Strategy Considerations

• Range Advantage: As the defensive player preflop, BB’s range is typically wider, but if they continue betting on the river, it often indicates a strong made hand or a bluffing intent.
• Board Texture: The board texture on the river is crucial. For example, if the river completes a obvious straight or flush, BB’s C-Bet likely represents a value bet; conversely, if the board is dry, the likelihood of a bluff increases.
• Opponent Tendencies: Consider the opponent’s fold rate on the river, as well as the balance of value hands and bluffs in BB’s own range.
• Bet Sizing: Usually the bet size on the river is larger (e.g., 2/3 pot or full pot), because the pot is larger and the opponent’s decision is more critical.

Notes

• Not all bets from the Big Blind on the river are called C-Bet; the prerequisite is that BB must be the last aggressive player preflop (i.e., the preflop raiser or the 3-bettor).
• If BB check-raises on the flop and then bets on the river, it is usually referred to as a “second bet” or “third barrel,” but still an extension of the continuation bet.
