CO Continuation Bet Leak (CO Continuation Bet Leak)

Overview

The CO (Big Blind) is the last to act preflop but is in the worst position postflop. A continuation bet (c-bet) is the preflop raiser's active bet on the flop. The CO continuation bet leak specifically refers to strategic weaknesses exposed when the big blind player, after defending their blind, makes a donk bet or check-raises and then continues betting on the flop.

Common Manifestations

• Overly wide range: The big blind player continuation bets with too many medium-strength hands (e.g., bottom pair, middle pair, draws), leaving them vulnerable to frequent bluff-raises from opponents with high fold equity.
• Improper bet sizing: The continuation bet size is disconnected from hand strength (e.g., small bets with strong hands, large bets with weak hands), easily spotted by observant opponents.
• Frequency imbalance: Continuation betting too frequently on specific flop textures (e.g., ace-high, connected boards), allowing opponents to execute precise counter-bluffs.

How It Can Be Exploited

Opponents can attack this leak by:

• Raising the big blind's continuation bet on dry boards (e.g., K-7-2 rainbow), forcing them to fold weak made hands.
• Calling lightly on wet boards (e.g., J-10-9 two-tone), using position to attack the upper end of the big blind's range on the turn or river.
• Tracking the big blind's continuation bet frequency across different flops and adjusting their calling range accordingly.

Improvement Suggestions

• Balance your continuation bet range: Maintain a reasonable ratio of value bets to bluffs (typically around 2:1 or 3:1).
• Adjust based on flop texture: Reduce continuation bet frequency on connected flops; increase it on dry boards.
• Leverage positional differences: Since the big blind is out of position postflop, prefer strategies like check-raising or slow-playing rather than continuation betting.
