Flop Range Betting Frequency Table: CO vs BB Dry Board

Position Scenario Description

Assume the preflop situation: The CO (Cutoff) raises to 3BB, and the Big Blind calls. The flop comes Q♠ 7♦ 2♣, a classic dry board with no flush draw possible and only a few straight draws (e.g., TJ, T9). The CO has position (IP) postflop, while the BB is out of position (OOP). In this scenario, the CO's betting frequency is typically high due to range advantage (CO's raising range is stronger than BB's defending range) and nut advantage (CO can hold AA, KK, AQ, etc., while BB rarely has QQ+ and few top pairs).

Recommended Range

On a Q72 rainbow board, the CO's recommended betting frequency is about 70%-80%, meaning most hands are worth a continuation bet (C-bet). The specific hand categories are as follows:

• Value bets (~25%-30%): All top pair or better, including KK+ (though KK+ would usually 4-bet preflop, this assumes no 4-bet occurred), AQ, KQ, QJ, QT, Q9s (suited), 77, 22. Note that QQ might 3-bet preflop to control the pot, but if it called, it is still considered a very strong hand here.
• Drawing bets (~5%-10%): JTs, T9s, 89s (gutshot or double gutshot straight draws), and backdoor flush draws (e.g., A♠X♠).
• Bluff bets (~35%-40%): Among all unpaired high cards (e.g., AK, AT) and low pairs (e.g., 44, 55), select hands that block the opponent's continuing range or have strong improvement potential. For example, AK blocks AA, KK, AQ, KQ and has an overcard draw; AT has similar blocking effects. Low pairs like 22-66 (excluding 77) are mostly recommended to check because they are weak with no improvement potential.
• Check range (~20%-30%): Includes weak pairs (e.g., 66-33, dominated by top pair), junk hands without draws (e.g., K2s, T2s – these should not have called preflop but if they are in the range, fold them), and some medium-strength bottom pairs (e.g., A7, K7) to balance the checking range and protect the later streets.

Range Construction Logic

The core basis for constructing the betting range is range advantage and nut advantage. The CO's preflop raising range is about 25%-30% of hands, while the BB's defending range is about 40%-50% but weaker. On a dry board like Q72 rainbow, the CO's range has a higher probability of hitting pairs and the top end is far stronger than the opponent's. Therefore, the CO can use a high-frequency small bet strategy (about 1/3 pot) to apply pressure and force the opponent to fold many unpaired hands. For balance, some draws and blockers are used as bluffs to avoid being easily exploited.

Additionally, blocker effects are crucial: For example, AK blocks AA, KK, AQ, KQ, weakening the opponent's calling range; AT blocks AQ, ATo, etc. Hence these hands are suitable for bluffing. Conversely, KJo also blocks KQ but has a weaker kicker and no overcard draw, so checking is recommended.

Adjustment Factors

Actual betting frequency should be adjusted based on these factors:

• Opponent type: Against tight-passive players (high fold rate), increase betting frequency; against loose-aggressive players (wide calling range), reduce bluffs and focus more on value.
• Bet sizing: On dry boards, small bets (1/3 pot) are usually sufficient to achieve fold equity; if using large bets (2/3+ pot), the overall betting frequency should decrease, and only the strongest hands and best bluffs should remain.
• Flop texture: If the flop has a flush draw or is Ace-high, the betting frequency needs reassessment. For example, on A72 rainbow, the CO's range has many Aces, so frequency should be higher.
• Stack depth: With shallow stacks (<40 BB), betting frequency should decrease because opponents are more prone to shoving; with deep stacks (>100 BB), high frequency can be maintained.

GTO Reference

According to GTO solver calculations for similar scenarios, the CO's recommended betting frequency on this flop is about 70%-80%, depending on bet sizing. With a 1/3 pot bet, the GTO frequency is about 75%; with a 2/3 pot bet, it drops to about 55%. Additionally, GTO mixes in some check strategies to protect medium-strength hands in the checking range (e.g., A7, K7). Players can use this as a baseline, but in practice, they should focus on exploiting opponent tendencies.

Practical Application

• Exploiting tight-passive players: If you observe that the opponent folds too often to large bets, increase your betting frequency to over 90%, even bluffing with very weak hands.
• Exploiting loose-aggressive players: When opponents frequently call with wide ranges, reduce pure bluffs, increase value bets, and occasionally check medium-strength hands to induce bluffs.
• Note your own image: If your C-bet frequency is perceived as aggressive, opponents may call more often, so you should mix in more checks.
• Use range tables: Practice memorizing betting frequency tables for different flops to develop intuition. In actual games, start by following the frequency, then adjust based on dynamics.

In summary, the flop range betting frequency table is a fundamental tool in poker strategy. On dry boards, high-frequency betting is often the most profitable approach. Mastering its logic and adapting flexibly can significantly improve your postflop performance.
