The Continuation Bet on the Flop: When to Bet and Which Size
When to C-bet, sizing strategy (1/3 pot vs 2/3 pot), and when to check back.
After this lesson you will be able to
decide whether to bet or check using two fundamental questions
select optimal continuation bet sizings tailored to board texture
exercise pot control with medium-strength hands via checking behind
You raised preflop, an opponent called, and on the flop they check to you. Betting on the flop as the preflop aggressor is called a continuation bet, or C-bet.
It succeeds for a simple statistical reason: an unpaired starting hand connects with the flop only one-third of the time. Two-thirds of the time your opponent holds nothing, and a modest bet claims the pot uncontested.

The Two Fundamental Betting Questions
Before placing any bet, ask yourself:
Will worse hands call? If hands weaker than yours will call, your bet is for value.
Will better hands fold? If your bet forces superior hands to fold, your bet is a bluff.
If the answer to both questions is "no", betting burns money: better hands call, and worse hands fold. In that scenario, the optimal action is to check.
A third secondary reason is protection: denying opponents free cards that could outdraw you. That is why betting second pair on a wet board can make sense even if value is marginal.
Sizing Tailored to Texture
Bet sizing is dictated by the board texture, not your specific hand strength — otherwise perceptive opponents will read your cards instantly.
Small Bet (25-33% pot). Dry and paired boards: K♦ 8♠ 2♣, 7♠ 7♦ 4♣. Opponents missed completely; a cheap bet exerts maximum leverage across your entire range with minimal risk.
Large Bet (60-75% pot). Wet and coordinated boards: J♥ T♥ 9♣, Q♠ 9♠ 8♦. Draws must pay an unfavorable price, and your made hands must build the pot before scary turn cards fall.
Overbet (> 100% pot). Polarized sizing reserved for spots where you hold significant nut advantage and your opponent is capped.
Key takeaways
A continuation bet (C-bet) leverages preflop aggression and the fact that opponents miss the flop 67% of the time.
Always ask: will worse call (value) or better fold (bluff)? If neither, check.
Size small (25-33%) on dry boards; size large (60-75%) on wet boards to charge draws.
Medium-strength hands with showdown value should check behind for pot control.
Test yourself: questions and answers
Approximately how often does an unpaired starting hand miss the flop completely (no pair or better)?
Answer: Roughly two-thirds of the time (~67%). An unpaired hand hits a pair or better only ~32% of the time, missing the flop completely roughly two out of three times.
What are the two core questions you must answer affirmatively before placing any bet?
Answer: Will worse hands call (value), or will better hands fold (bluff)?. Every profitable bet serves either to extract value from worse hands or force folds from better hands.
Which flop texture calls for a smaller C-bet sizing (25% to 33% of the pot)?
Answer: K♦ 8♠ 2♣ (Dry, uncoordinated, rainbow). Dry rainbow boards feature few draws and static equities, allowing a small bet to accomplish the objective with minimal risk.
You hold second pair with a medium kicker (e.g. 8s 7s on K♦ 8♣ 2♠) in position. What is the standard strategic play?
Answer: Check behind for pot control and preserve your showdown value. Second pair has showdown value against unpaired cards. Checking behind keeps the pot manageable without building a pot where only better calls.
Why should you size up your C-bet (66% to 75% pot) on wet, coordinated boards like J♥ T♥ 9♣?
Answer: To charge numerous straight and flush draws an unfavorable price while extracting maximum value with your made hands. Dynamic boards contain many strong draws that will outdraw you if offered cheap prices. Larger sizing denies correct pot odds.
