Flop Range C-bet Frequency Table: A Complete Guide from Range Construction to GTO Adjustments
67 views
This article provides a detailed analysis of the construction principles and applications of flop range betting frequency tables, covering position scenarios, recommended ranges, construction logic, adjustment factors, and GTO references, helping players formulate precise betting strategies based on hand types and board structure.
Position Scenario Description
The flop betting frequency table (CBet frequency table) mainly depends on the positional relationship between the two players, preflop ranges, and board structure. This article focuses on the scenario where the preflop raiser (PFR) is in position (e.g., BTN vs BB), as this is the most common and strategically rich scenario. Assume effective stack size is 100BB, preflop BTN opens to 2.5BB, BB calls.
Recommended Range
Below is a simplified flop betting range based on GTO principles (for a dry flop like K♠7♦2♣):
- Value Bet (approx. 30% of total range): Top pair with good kicker or better (e.g., AK, KQ), two pair or better, sets.
- Bluff Bet (approx. 20%): Backdoor flush draw + gutshot straight draw, bottom pair + backdoor straight draw, complete air with blocking cards (e.g., A-high blocking top pair).
- Check Range (approx. 50%): Medium-strength hands (e.g., middle pair, bottom pair), weak draws (no backdoor), and air hands with little improvement potential.
Example: Assume BTN's preflop opening range includes all pairs, all Ax, all suited connectors (54s+), and some offsuit broadways (QJo+). On a K♠7♦2♣ flop, value bet hands are {KK+, AK, KQ, 77, 22, KJs}; bluff bet hands are {AJs (backdoor flush + gutshot), A5s (backdoor flush + gutshot), 65s (backdoor flush + gutshot), ATo (blocks K)}; check hands are {QQ-JJ, 99-88, 76s, other weak Ax, etc.}.
Range Construction Logic
Range construction follows a polarized strategy: the ratio of value hands to bluffs determines the betting frequency. The key is to balance hand strength distribution so that the opponent's calling range is unprofitable.
Value hands need at least 50% equity against the opponent's calling range. Bluff hands require improvement potential (e.g., draws) or the ability to block the opponent's strong hands. The betting frequency in the table is typically 50%-70% of the total range, depending on the flop structure:
- Dry Flop (e.g., K72 rainbow): High bet frequency (approx. 65%) because the opponent is unlikely to hit, and bluffs are efficient.
- Wet Flop (e.g., J♠T♦9♣): Low bet frequency (approx. 45%) because the opponent's range connects well, requiring more solid value.
Adjustment Factors
In practice, the frequency table must be dynamically adjusted based on the following factors:
- Opponent Style: Increase bluff frequency against opponents with high fold rates; decrease bluffs against calling stations.
- Stack Depth: Use smaller bet sizes (approx. 1/3 pot) when shallow-stacked; use 2/3 pot when deep-stacked.
- Preflop Range Width: If the preflop range is wider (e.g., BTN vs BB), bet frequency should be higher to deny the opponent's equity.
- Community Cards Dynamics: A-high flops generally increase bet frequency because hitting an A is a strong hand.
GTO Reference
According to modern GTO solvers (e.g., PioSolver, MonkerSolver), in a BTN vs BB 100BB flop scenario:
- Dry Flop: Recommended CBet frequency ~65%, with a value-to-bluff ratio of 1:1 to 1.2:1 (slightly more value than bluffs).
- Moderately Connected Flop (e.g., 9♠7♦5♣): Frequency ~55%, with a reduced bluff ratio (approx. 1:1.5).
- Very Wet Flop (e.g., 8♠7♠6♥): Frequency drops to 40%, and bet size should be small (approx. 1/3 pot) to avoid being raised.
Note: GTO frequencies are just a baseline; exploitative adjustments are often more profitable in practice.
Practical Application
- Previsualize the Scenario: Without looking at your cards, first determine whether the flop structure is dry, connected, or wet, and set a baseline frequency.
- Categorize Your Hand: Sort your hand into one of three categories: value, bluff, or check, and strictly follow the plan.
- Bet Sizing: Use 2/3 pot (polarized sizing) on dry flops; use 1/3 pot (linear range) on wet flops.
- Adjustment Examples:
- If the opponent's flop fold rate is as high as 80%, increase bluff proportion to 40% on all flops.
- If the opponent frequently check-raises, reduce bluffs and expand your check-call range.
Remember: The frequency table is a tool, not a dogma. Continuously observe opponents' weaknesses and adjust to exploitative strategies to maximize profits.
