Flop C-Bet Basics

What is a Continuation Bet?

A continuation bet (abbreviated as C-bet) refers to the act of continuing to bet on the flop as the preflop raiser. The core logic is that preflop you have a range advantage (because you raised voluntarily), and by betting on the flop you can force opponents to fold weak hands while gaining information and building the pot.

When to Make a Continuation Bet

1. The Flop Favors Your Range

• High-card flops: When the flop contains A, K, or Q, as the preflop raiser you are more likely to hold these cards, while your opponent's range lacks top-end strength, making a C-bet highly successful.
• Dry flops: Such as rainbow boards with no straight draws (e.g., K-7-2 offsuit). Opponents find it difficult to hit strong hands, leading to high fold rates.
• You have many draws: Even on a wet board, if your range includes many flush/straight draws, betting can balance value and bluffs.

2. Opponent Range Characteristics

• Opponent's calling range is weak: For example, defenders from the blinds or cold callers preflop often hold medium-strength hands and are prone to folding against a continuation bet.
• Opponent is a tight-passive player: Such players tend to fold to bets unless they hit a strong hand.
• Opponent has a high fold-to-cbet percentage: You can use HUD data or historical hands to determine this.

3. Positional Advantage

• In position (e.g., on the button): You can see the opponent's action before deciding, making a continuation bet safer.
• Out of position (e.g., in the small blind): A C-bet requires more caution, as opponents may exploit your range weakness by raising.

Bet Sizing Choices

• Dry flops: Recommended 1/3 to 1/2 pot. For example, with a pot of 100, bet 33-50. A smaller bet forces weak hands to fold while minimizing losses.
• Wet flops: Recommended 2/3 to 3/4 pot or even pot-sized. For example, with a pot of 100, bet 70-100. On wet boards, opponents have more draws; a larger bet denies them equity realization and builds value.
• When you know the opponent has a high fold rate: Use a smaller bet (1/3 pot) to reduce the cost of bluffing.

Common Pitfalls and Adjustments

1. Over-Continuation Betting

A C-bet frequency that is too high on the flop (e.g., over 70%) can be exploited by sharp opponents, who will punish you with raises or check-raises. It is advisable to C-bet frequently on dry boards against weak players, but reduce frequency against good players.

2. Not Planning for Future Streets

If your C-bet is called on the flop, you need to plan your turn action in advance. For example, after betting on a draw-heavy board, what will you do on the turn if the draw misses? If you have no plan, it is often better to check.

3. Ignoring Preflop Range Disparity

As the preflop raiser, your range typically includes more high cards, but the flop may not cooperate. For instance, if you open from UTG and the flop comes 9-8-7, your unpaired hands like A-K, A-Q miss, while the opponent's range may contain more connected hands. In such cases, a C-bet has low value, and checking is better.

4. Improper Response to Check-Raise

When an opponent check-raises on the flop, evaluate: Does your C-bet range contain many bluffs? Do you have enough draws or strong hands to continue? If you C-bet too frequently, you may be forced to fold too many hands against a raise, leading to losses. General advice: against a small raise, continue with draws and top pair or better; against a large raise, fold weak top pair and below.

Practical Examples

Example 1: You hold A♠K♣ and raise to 3BB from the CO. The button calls. The flop comes K♥7♠2♦ (rainbow board). You have top pair top kicker, pot is 7.5BB. This is an excellent spot for a continuation bet: the board is dry, your range has many K's and overpairs, and the opponent's fold rate is high. Recommended bet: about 2.5-3BB (1/3 pot).

Example 2: You hold J♦T♦ and raise to 3BB on the button. The big blind calls. The flop comes 8♥9♣5♠. You have a gutshot straight draw (needing a 7 or Q), but the board is wet, and the opponent's range may include straight draws or top pair. A continuation bet is reasonable here, but the sizing should be larger (e.g., 2/3 pot) to deny the opponent's equity realization. If called and the turn doesn't complete your draw, consider checking or bluffing depending on the opponent.

Summary

The continuation bet is a fundamental yet crucial strategy in Texas Hold'em. The key is to adjust your frequency and sizing based on the flop structure, opponent type, and your hand strength. Beginners should start by using at least a 50% frequency on dry boards against weak players, gradually learning to adapt flexibly. Remember: a continuation bet is not mandatory; sometimes checking is the superior play.
