Flop C-Bet Basics: When to Bet and How Much

What is a Continuation Bet?

A Continuation Bet (C-bet) refers to the action of the preflop aggressor (the raiser or 3-bettor) continuing to bet on the flop. It leverages preflop range advantage and position to force opponents to fold or to bet for value.

Core Logic of the Continuation Bet

• Range Advantage: The preflop aggressor typically holds a stronger range (e.g., the raiser's range is tighter/stronger than the caller's), making it more likely they hit strong combos on the flop.
• Denying Equity: Even when you miss, betting forces opponents to fold draws or marginal made hands, preventing them from drawing out on you.
• Value Extraction: When you hit top pair or better, you bet to extract value from weaker hands.

Key Factors in Deciding Whether to C-bet

1. Flop Texture

Different flop textures affect your range advantage and opponents' willingness to call.

• Dry Board (e.g., K♠7♦2♣): Favorable for the raiser. Opponents struggle to hit strong hands, so you can bet your entire range (including air). Example: The big blind calls your preflop raise, flop comes K72 rainbow, you C-bet about 2/3 pot, opponents fold most of the time.
• Wet Board (e.g., 9♠8♠6♣): Favorable for the caller. Opponents have many draws and are less likely to fold. Here, reduce betting with air and focus on strong made hands and draws.
• High Card Boards (e.g., A♠Q♦J♣): Align well with your preflop raising range, allowing high-frequency C-betting.
• Low Card Boards (e.g., 7♥5♦3♠): The raiser's range advantage diminishes; if your preflop raising range is tight (e.g., only high cards), your hit rate on such boards is low, so proceed cautiously.

2. Opponent Type

• Tight-Passive Players: C-betting is effective; they fold often.
• Loose-Passive Players: They like to call but rarely raise. Bet for value, but be cautious with air.
• Loose-Aggressive Players: They may raise with draws or junk, putting you in tough spots. Balance your range and avoid folding too much.

3. Position and Number of Players

C-betting is most effective in heads-up pots. In multi-way pots, the success rate drops because opponents' ranges are wider. Tend to bet only with strong hands.

C-bet Sizing

• Dry Board: A small bet (about 1/3 pot) suffices, as opponents have few draws.
• Wet Board: A large bet (about 2/3 to 3/4 pot) to punish draws and make opponents fold marginal hands.
• Medium Boards: Standard sizing (about 1/2 pot) works generally.
• Draw-heavy Boards: If there are flush or straight draws on the flop, increase the sizing appropriately.

Common C-bet Mistakes

• Automatic C-betting: Believing you must bet every time you raised preflop. In reality, adjust based on board texture and opponent.
• Fixed Sizing: Using the same size on all boards makes your strategy easy to read.
• Ignoring Balance: If you only bet when you have a strong hand, opponents will catch on. Mix in some air bets on dry boards.

Example Analysis (Typical Situations)

Scenario 1: You raise A♦K♠ to 3BB from the cutoff, big blind calls. Flop: J♠T♦5♣. Analysis: This board is moderately wet. You have a backdoor straight draw but no top pair. The big blind's range includes many Jx and Tx hands, plus draws. Recommended: C-bet about 2/3 pot, representing top pair or better. If called, check-fold on the turn unless you improve.

Scenario 2: You raise 7♣7♠ from the button, big blind calls. Flop: A♠K♦Q♣. Analysis: This board is very dry (all high cards). Your 77 is a marginal hand. Your range contains A, K, Q, which is advantageous, but 77 is not at the top of your range. C-betting exposes weakness; it's better to check, hoping to hit a set on the turn or river, or to bluff later.

Summary

The continuation bet is a fundamental attacking tool on the flop, but it should not be mindlessly executed. Flexibility is key: adapt based on flop texture, opponent tendencies, position, and number of players. Through practice and observation, build your own C-betting strategy framework.
