Minimum Defense Frequency
What Does Minimum Defense Frequency Mean in Poker?
The minimum defense frequency (MDF) is the percentage of hands a player must defend against a bet to prevent opponents from exploiting them with bluffs. It is a concept derived from game theory, ensuring that a player’s range remains balanced and difficult to exploit.
When You Might Hear Or Use The Term Minimum Defense Frequency:
This term is often discussed in strategic gameplay conversations, especially in situations where players must decide whether to call or fold against aggressive betting opponents. It’s commonly mentioned in coaching sessions, poker forums, and advanced strategy discussions.
In-Game Example:
Suppose you’re facing a pot-sized bet on the river. Using the MDF concept, you should defend with at least 50% of your range. This means if you can’t call with 50% of your hands, you’re folding too much, giving your opponent a profitable bluff opportunity.
Strategy / Tips:
- Best Practice: Use MDF to maintain a balanced range, ensuring opponents can’t easily profit from bluffs.
- Common Mistake: Over-folding, especially on the river, which allows opponents to exploit with frequent bluffs.
- Pro Tips: Adjust your MDF based on opponent tendencies. Against tight players, you may need to defend less, while against aggressive players, maintaining a higher MDF is crucial.
- Differences playing over the table vs online: In live games, physical tells can influence your defense decisions, while online, you’ll rely more on betting patterns and timing tells.
