Flop Range Betting Frequency Table

Position Scenario Explanation

In Texas Hold'em, flop betting ranges and frequencies are highly dependent on position. Typically, the preflop aggressor (e.g., BTN vs BB) has a range advantage on the flop, while the defender (BB) must be more cautious. This guide uses a common heads-up pot (preflop raiser vs preflop caller) as an example, providing reference betting frequencies for different positions. Scenario: effective stack 100BB, flop is a medium-connected rainbow board (e.g., J♠8♥3♦).

Recommended Ranges (Hand Type Descriptions)

Preflop Raiser (e.g., BTN vs BB)

• Continuation Bet Range (approx. 70% frequency):
  • Strong hands above top pair: AJ, KJs, QJs, JJ, 88, etc.
  • Draws: Flush draws, open-ended straight draws (e.g., T9, Q9).
  • Backdoor draws: e.g., A♠K♠ (backdoor flush + backdoor straight).
  • Air: Some hands that completely miss the flop, e.g., A♦5♦ (no pair, no draw), for balance.
• Check Range (approx. 30% frequency):
  • Medium-strength hands: e.g., A8, 99, 77 (fear of being raised).
  • Weak draws: e.g., K♠4♠ (bottom pair + backdoor).
  • Overcard gutshots: e.g., AKo (no draw), occasionally checked to control pot.

Preflop Caller (e.g., BB vs BTN)

• Bet Range (approx. 25% frequency):
  • Strong hands above top pair: two pair or better (J8, 88, 33) and sets.
  • Strong draws: Straight flush draws, combo draws (e.g., T♠9♠).
  • Bluffs: Low pair + gutshot (e.g., 76), or weakest hands with backdoor draws.
• Check-Raise Range (approx. 15% frequency):
  • Flush draws: e.g., A♠5♠.
  • Open-ended straight draws: e.g., T9o.
  • Weak pairs: e.g., 66 (as semi-bluff).
• Check-Call Range (approx. 60% frequency):
  • Middle pair, bottom pair, gutshots, overcards, etc.

Range Construction Logic

The core principle of range construction is polarization and balance. On the flop, the raiser should tend toward a linear range (value-heavy) with enough bluffs to avoid being exploited, while the defender should adopt a more polarized range (strong hands + draws) to avoid being trapped with medium-strength hands.

Taking BTN vs BB as an example:

1. Value Bet: All very strong hands (e.g., top pair+) must bet for value.
2. Bluff Bet: Select hands that cannot win at showdown, such as backdoor draws or complete air, while considering blockers (e.g., A blocks top pair).
3. Check: Medium-strength hands (e.g., middle pair) check to control pot, avoiding being raised into a tough spot; occasionally check some strong hands to protect the checking range.

Adjustment Factors

The following factors require dynamic adjustment of betting frequency:

• Flop Texture: On dry boards (e.g., A♠7♦2♣), the raiser bets more frequently (approx. 80%); on wet boards (e.g., J♥T♠9♦), it drops to 50%.
• Stack Depth: Deep stacks (200BB) increase betting frequency with draws; short stacks (30BB) reduce bluffs.
• Opponent Tendencies: Against passive opponents, increase betting frequency; against aggressive opponents, reduce bluffs and strengthen check-raise range.
• Preflop Range: If the preflop raising range is tight, flop betting frequency can be higher; if loose, it should be lower to maintain balance.

GTO Reference

In GTO (Game Theory Optimal) strategy, flop betting frequency is not a fixed value but adjusts based on ranges, pot odds, and opponent reactions. Using BTN vs BB on J♠8♥3♦ rainbow board as an example, GTO recommends:

• BTN continuation bet frequency approx. 67% (betting 33% pot), with a value-to-bluff ratio of about 1.5:1.
• BB's betting frequency approx. 12%, raising frequency approx. 10%, and checking the remaining 78%.

In practice, refer to the following simplified frequency table (based on 100BB, standard 3bb open):

Practical Application

In actual play, follow these steps to quickly construct a flop range:

1. Identify flop texture (dry/wet/neutral).
2. Determine base frequency based on position (as per table above).
3. Manually filter hands: Start with strong hands above top pair, then add draws, finally fill in air to reach target frequency.
4. Adjust: If opponent folds frequently, increase bluffs; if opponent calls too much, reduce bluffs and increase value bets.

Example: You open 3bb on BTN, BB calls, flop J♠8♥3♦. Your range contains about 200 combos. To bet at 67% frequency, select about 134 combos to bet. First select all Jx (e.g., AJ, KJ, QJ) ~42 combos, then 88, 33 ~9 combos, draws (e.g., T9, QT ~24 combos), finally fill in air like A5, A4 ~59 combos. The check range retains the remaining 66 combos, including some weak pairs (e.g., 99, TT) and completely missed A-high (e.g., AK).

With repeated practice, you can make reasonable decisions in seconds.
