Flop C-bet Basics: When to Bet, When to Check

What is a Continuation Bet?

A Continuation Bet (Continuation Bet, abbreviated as C-bet) refers to a bet made on the flop by the preflop aggressor (usually the preflop raiser). It is called "continuation" because it continues the aggressive action from preflop.

The core objectives of a C-bet are:

• Force opponents to fold and win the pot immediately.
• Even if called, gain information and establish your range image.
• Balance your value bets and bluffs to make it difficult for opponents to read you.

Baseline Frequency for Continuation Bets

Generally, a C-bet frequency of around 60%-70% on the flop is reasonable, but it depends on board texture, opponent type, and your range.

• On dry boards (e.g., K-7-2 rainbow), your range contains more overpairs and top pairs, and opponents are unlikely to hit. The C-bet frequency can be higher (70%-80%).
• On wet boards (e.g., 9-8-6 two-tone), your range has more weak hands and opponents are more likely to connect. The C-bet frequency should be lower (40%-50%).

Key Factors in Deciding Whether to C-bet

1. Board Texture

• Dry boards: No straight or flush draw possibilities, e.g., A-4-2 rainbow. Your C-bet has high bluff value because opponents almost never have strong hands.
• Wet boards: Many draws present, e.g., 9-8-7 two-tone. When you C-bet, opponents' calling ranges are wider, and your marginal hands can easily be outdrawn. It is recommended to bet more with strong hands and check with weak ones.

2. Your Position

• In Position (BTN/CO): You can C-bet more frequently because you have the last action postflop and can adjust based on opponent reactions.
• Out of Position (BB/SB): C-bet frequency should be lower because you need a stronger range to counter opponents' raises or calls.

3. Opponent Type

• Loose-Passive Players: They call a lot but have high fold rates postflop (especially when missing the flop). Against such opponents, C-betting is almost always profitable.
• Tight-Aggressive Players: They have narrow preflop ranges and strong postflop defense. C-betting against them requires more caution, especially on unfavorable boards.
• Calling Stations: They rarely fold. Use C-bets with value hands and very few bluffs.

4. Your Hand Strength

• Value Bet: Strong hands like top pair or better almost always warrant a C-bet, unless the board is very wet and you want to control the pot.
• Draws: Such as straight draws or flush draws. C-betting can gain fold equity and build the pot for when you hit, but be aware of the risk of being re-raised.
• Air: Can C-bet as a bluff on dry boards, but be cautious on wet boards or against calling stations.

Sizing of Continuation Bets

• Small bet: On dry boards, bet about 1/2 pot because opponents fold frequently.
• Large bet: On wet boards, bet 2/3 pot or more to punish draws and protect your value hands.

Common Mistakes

• C-betting on every board, making it easy for opponents to exploit you.
• Over-C-betting in multiway pots, as hit rates decrease and you need a stronger range.
• Ignoring board dynamics by betting weak hands on wet boards, leading to being re-raised and put in tough spots.

Practical Examples

Example 1: You raise on the BTN with K♦Q♦, BB calls. Flop: K♠-7♥-2♣.

• Analysis: Dry board, you have top pair. C-bet 1/2 pot. BB will usually fold all unimproved hands. If they call or raise, reassess.

Example 2: You raise in the CO with A♠5♠, BTN calls. Flop: J♠-T♠-3♣.

• Analysis: Wet board, you have a flush draw but weak A-high. C-bet about 2/3 pot to force folds, and if called, you still have drawing potential.

Summary

The continuation bet is the most important attacking weapon on the flop, but it requires flexible adjustments based on board, position, opponent, and hand strength. Core principle: C-bet more on dry boards, be cautious on wet boards; in position C-bet more, out of position less; bet more against opponents with high fold rates, bluff less against stubborn ones. Mastering these basics will significantly improve your postflop win rate.
