Flop C-Bet Basics: Timing, Sizing, and Strategy

What is a Continuation Bet (C-bet)

A continuation bet (C-bet) refers to the action of the preflop aggressor (the raiser or 3-bettor) making the first bet on the flop. Since you have shown strength preflop, continuing to bet postflop maintains your aggressive stance, forcing opponents to fold or building the pot for your strong hands.

When Should You C-bet

1. Favorable Flop Structure

• Dry Board: e.g., K♠7♦2♣. Opponents are less likely to have top pair or draws, making the C-bet more successful.
• High Card Board: When the flop contains A, K, or Q, your range often includes these cards, increasing the chance opponents fold.
• Unconnected: e.g., 9♠3♦2♣. Opponents rarely have strong draws or pairs.

2. Weak Opponent Range

• Against a calling station, C-betting for value is more effective, but note they may call with weak pairs.
• When an opponent has a wide preflop calling range and misses the flop, their fold rate is high.

3. Your Range Advantage

• As the preflop raiser, your range typically contains more high cards and strong pairs, while your opponent's range is weaker.
• In three-way or multiway pots, reduce C-bet frequency because opponents are more likely to hit the board.

Bet Sizing

• Dry Board: Bet about 33%-40% of the pot. For example, with a pot of 100, bet 33-40. A small bet can force folds while controlling risk.
• Wet Board: Bet about 66%-75% of the pot. For example, with a pot of 100, bet 66-75. A large bet penalizes draws and protects your made hands.
• Typical Case: On the flop, most C-bet sizes range from 1/3 to 2/3 of the pot.

How Flop Structure Affects C-bet Strategy

Dry Board (e.g., A♠8♦2♣)

• High C-bet frequency, about 70%-80%.
• Bet small because opponents rarely can continue.
• Even if you missed completely, you can represent an A or a high pair.

Wet Board (e.g., J♠T♠9♣)

• Low C-bet frequency, about 40%-50%.
• Bet larger to discourage draws.
• If you don’t have a strong hand or a draw, be cautious, as opponents may have many draws or made hands.

Medium Board (e.g., Q♠7♦5♣)

• Medium frequency, about 60%.
• Adjust bet sizing based on the specific board.

Common Adjustments

1. Multiway Pots

• Reduce C-bet frequency because opponents are more likely to hit the board.
• Only bet when you have a strong hand or a clear range advantage.

2. Position

• In position (e.g., the button), you can C-bet more frequently because you control the pot and can see a free card.
• Out of position (e.g., the blinds), be more cautious with C-bets, as opponents might raise and put you in a tough spot.

3. Opponent Type

• Against tight-passive players (nits): C-bet frequently, as they fold often.
• Against loose-aggressive players: C-bet less frequently, as they may raise or have a wide calling range.

Examples

Example 1: You raise with A♠K♣ on the button, and the big blind calls. The flop is K♠7♦2♣.

• This is a dry board, and you have top pair top kicker.
• Bet about 33% of the pot for value, forcing opponents to fold.

Example 2: You raise with A♠K♣ from UTG, and the button calls. The flop is J♠T♠9♣.

• This is a wet board, and you only have high cards.
• Consider checking, as opponents may have many made hands or draws, making a C-bet risky.

Summary

The continuation bet is a core flop strategy, but it’s not automatic. You need to adjust your frequency and sizing based on flop structure, opponent type, position, and the number of players in the pot. Bet more on dry boards, less on wet boards; bet more in position, less out of position. With practice, you’ll be able to more accurately determine when a C-bet is profitable.
