Flop C-bet Basics: When to Bet and How to Build Ranges

What is a Continuation Bet?

A continuation bet (C-bet) is when the preflop aggressor (usually the preflop raiser) continues to bet on the flop. The core logic: you showed strength preflop, and you continue to represent strength postflop, forcing opponents to fold or setting up a value bet.

Why Make a Continuation Bet?

• Take down the pot immediately: Opponents often have a high fold rate on the flop, especially when the flop doesn’t connect with their range.
• Balance your range: If you only bet when you have a strong hand, opponents can easily exploit you. C-betting makes it harder for them to read your hand strength.
• Establish an aggressive image: Frequent C-bets make opponents more passive on later streets.

Flop Structure Determines Bet Frequency

Flop structure is the most critical factor in deciding whether to C-bet. It’s generally divided into three types:

1. Dry Flops (e.g., K♠7♦2♣)

• Characteristics: No straight draws, no flush draws; only a few top pairs or middle pairs.
• Strategy: High frequency (about 70-80%). Opponents rarely hit, and your range advantage is clear.
• Example: You call from the big blind and the flop comes K♠7♦2♣. Your range contains many Kx hands, while your opponent’s range has fewer Kx, so you can C-bet frequently.

2. Connected Flops (e.g., 9♠8♠7♣)

• Characteristics: Many straight draws and flush draws; high probability of hitting top pair or a draw.
• Strategy: Lower frequency (about 40-50%). Opponents hit often, so your bluffs are more likely to be called.
• Example: Flop is 9♠8♠7♣. Your range doesn’t have many hands above top pair, while opponents have many pairs and draws; bet cautiously.

3. Medium Flops (e.g., J♠8♦4♣)

• Characteristics: Some connectivity but not as wet as a connected flop.
• Strategy: Medium frequency (about 55-65%). Adjust based on opponent type.

Position and Range Advantage

• In position: You can C-bet more frequently because you have information advantage and can control the pot size.
• Preflop raiser vs caller: The raiser’s range is usually stronger, so the C-bet frequency can be higher. But note: if the preflop raiser’s range is very wide (e.g., BTN vs BB), the flop range advantage may diminish.

Adjusting to Opponent Types

• Tight-passive: High C-bet frequency; they fold often.
• Loose-aggressive: Lower C-bet frequency; use more value bets because they call or raise frequently.
• Calling stations: Only C-bet with strong hands; they rarely fold.

Bet Sizing

• Dry flops: Bet about 1/3 pot – enough to make draws fold while lowering the cost of your bluffs.
• Wet flops: Bet about 2/3 pot or larger – to deny correct odds for draws.
• Standard situations: 1/2 pot is a common choice.

Common Mistakes

• Over-C-betting: Betting too often on wet flops, allowing opponents to easily call or raise.
• Not adjusting range: In multiway pots, drastically reduce C-bet frequency because more opponents hit the flop.
• Ignoring preflop ranges: For example, UTG vs BTN: UTG has a stronger range, but BTN’s calling range is more concentrated and may overtake postflop.

Summary

The continuation bet is a core weapon on the flop, but you must adjust flexibly based on flop structure, position, and opponent type. Remember: bet more on dry flops, less on wet flops; bet more in position, less in multiway pots. Through practice and review, you’ll gradually master the rhythm of C-betting.
