Flop Range Betting Frequency Table: Construction and Adjustment Guide

Position Scenario Description

Flop betting frequency depends on multiple factors: position (in position / out of position), flop structure, opponent range, and table dynamics. This article discusses the frequency range of flop continuation bets (C-bet) using the most common scenario of "preflop raiser vs caller".

Assume preflop: CO opens, BB calls. On the flop, CO as the preflop raiser has range advantage and nut advantage. BB's calling range is wider but lacks top-tier strong hands.

Recommended Ranges

Under different flop structures, CO's C-bet frequency should vary significantly:

• Dry low-card flops (e.g., 7-2-2 rainbow): CO can bet at a frequency as high as 80%-90%. Because BB rarely hits, and CO can represent all overcards and overpairs. The betting range includes: all overpairs, top pair or better, overcards with backdoor draws (e.g., AK, AQ), and a small amount of air (e.g., KQo).
• Moderately connected flops (e.g., 9-8-3 two-tone): betting frequency around 60%-70%. Value hands need protection, balanced with some draws and air. Range includes: top pair or better value, all straight draws and flush draws, overcards with backdoor draws, and a few bottom pairs or weak draws (e.g., A5s with backdoor straight and flush).
• Wet high-card flops (e.g., K-Q-J two-tone): betting frequency drops to 40%-50%. Because BB can hit straights or two pair, CO must be cautious. Range includes: top pair top kicker or better, two pair or better, all strong draws (combo draws), some middle pair (e.g., AT) as a check-raise range, and some weak draws and air (e.g., A5s) bet at lower frequency.

Range Construction Logic

The core principle of the flop range betting frequency table is: polarized vs linear.

• Linear range: Bet all hands better than opponent's range, check weaker hands. Suitable for dry, low flops where CO has a huge range advantage.
• Polarized range: Betting range consists of strong value hands and air, with medium-strength hands checking. Suitable for wet, high flops where medium strength is vulnerable to being reversed.

Specific construction steps:

1. Determine the preflop raiser's nut advantage: CO has more nuts on K-Q-J flops (e.g., AK, QQ, JJ), but BB also has straights (T9, AT, etc.).
2. Calculate range advantage: Use range calculators or simplify: CO has clear range advantage on low flops, advantage shrinks on high flops.
3. Choose bet sizing: Typically small bets (33% pot) for linear ranges, large bets (75% pot) for polarized ranges. Betting frequency must match sizing: high frequency (70%+) with small bets, low frequency (below 40%) with large bets.

Adjustment Factors

• Opponent tendencies: Against frequent folders, increase betting frequency; against calling stations, reduce air bets.
• Stack depth: Deep stacks (>100BB) favor polarization; shallow stacks (<40BB) favor linearity.
• Preflop range: If CO's preflop raising range is tight (e.g., only premium hands), flop betting frequency can be higher; if wide, frequency should decrease.
• Flop structure: Rainbow, double-suited, paired boards, etc., all have effects. For example, paired flops (e.g., 8-8-3) reduce opponent hitting probability, allowing higher betting frequency.

GTO Reference

In GTO (Game Theory Optimal) strategy, flop betting frequency should make opponent's check-raise and defense indifferent. Typical GTO example (CO vs BB, flop T-7-2 rainbow):

• CO bets about 70% of the time, with value hands (top pair or better) 50%, draws (e.g., backdoor flush draws) 20%, and air 30%.
• Checking range mainly consists of medium strength (e.g., 88, A7), weak top pair (e.g., KT), and some unpaired overcards (e.g., AQ).

Note: GTO frequencies are theoretically optimal, but in practice, adjust based on opponent deviations.

Practical Application

1. Build benchmark frequency tables: Simulate common flops in poker software, record your betting frequency, and compare with recommended values. For example, on a 7-2-2 flop, if you only bet 60%, you may be missing value.
2. Targeted adjustments: Against tight-passive players, increase betting frequency on wet flops (they fold too much); against loose-aggressive players, decrease frequency and increase check-raises.
3. Practice balance: Bet air on dry flops (e.g., KQo on 7-2-2); bet strong draws on wet flops (e.g., flush draw on K-Q-J).
4. Review and analyze: After each session, check hand histories to evaluate whether your betting frequency on different flops aligns with strategy.

Remember: frequency tables are guiding frameworks, not absolute rules. The core is to control the decision tree through frequency, making opponents difficult to counter.
