Improve your poker game with this in-depth minimum defense frequency guide. Proven tactics and analysis from professional grinders.
## Minimum Defense Frequency Explained
Minimum Defense Frequency (MDF) is the minimum percentage of your range you must continue with (call or raise) to prevent an opponent from profitably bluffing with any two cards. MDF = 1 - [bet / (pot + bet)].
Against a half-pot bet: MDF = 1 - (50/150) = 67%. You should defend at least 67% of your range. Against a pot-sized bet: MDF = 1 - (100/200) = 50%. Against an overbet of 2x pot: MDF = 1 - (200/300) = 33%.
MDF is a theoretical guideline, not a strict rule. Adjust based on opponent tendencies: defend more than MDF against excessive bluffers, less than MDF against opponents who rarely bluff.
## Applying This at the Tables
Understanding minimum defense frequency explained is one thing — executing it under pressure is another. Practice by focusing on this specific concept for an entire session, then review relevant hands afterward to evaluate your execution.
