C-Bet from BB

Definition and Context

A C-Bet from BB refers to a continuation bet (c-bet) made by the player in the Big Blind (BB) position, but only when that player was the preflop raiser. In standard poker terminology, a c-bet is a bet made on the flop by the player who took the aggressive action on the previous street (usually the preflop raiser). Therefore, a bet from the BB on the flop qualifies as a c-bet only if the BB raised preflop—for example, by defending against a late-position steal or isolating a limper. If the BB simply called a raise preflop and then leads out on the flop, that bet is called a donk bet, not a c-bet.

Strategic Considerations

When the BB raises preflop and the opponent calls, the BB has the initiative and often a range advantage on many flops. The BB can use this to c-bet frequently, especially on boards that favor their perceived range (e.g., low or connected flops). Key factors affecting c-bet frequency from the BB include:

• Range Advantage: The BB’s raising range is typically stronger than a calling range from the opponent, who may have called with a wider, weaker set of hands. This allows the BB to c-bet more aggressively.
• Board Texture: On dry boards (e.g., K-7-2 rainbow), a small c-bet can take down the pot often. On wet boards (e.g., 9-8-6 with draws), the BB should be more cautious or use larger sizes.
• Opponent Tendencies: Against tight opponents, c-betting frequently is profitable. Against calling stations, the BB may need to value-bet more and bluff less.
• Stack Sizes: In tournaments with ICM pressure, c-betting decisions become more nuanced; the BB may avoid marginal bluff c-bets.

Common Misconceptions

A frequent mistake is labeling any flop bet from the BB as a "c-bet." As noted, this is only correct when the BB was the preflop raiser. Calling a raise and then betting is a donk bet, which has different strategic implications (often polarizing or representing specific draws). Understanding this distinction is crucial for proper hand reading and strategy adjustment.

Example Scenario

Consider a $1/$2 cash game. The BU (button) opens to $6. The SB folds, and the BB raises to $20 with A♠K♠. The BU calls. The flop comes K♥7♦2♣. The BB now c-bets $30 into a $41 pot. This is a classic c-bet from the BB—the BB was the preflop aggressor and continues with a value bet on a favorable flop.

In contrast, if the BB had called the $6 raise and then bet on the same flop, that would be a donk bet, not a c-bet, because the preflop aggressor (the BU) has not yet acted.

Conclusion

The "C-Bet from BB" is a specific application of the standard c-bet, only valid when the BB raised preflop. Properly identifying this situation helps players apply appropriate frequencies and sizes based on range, board, and opponent dynamics.
