What Does MDF Mean in Poker?
MDF, or Minimum Defense Frequency, is a poker concept used to determine the percentage of hands a player should continue with to prevent an opponent from profitably exploiting them with frequent bluffs. It ensures the player is not folding too much when facing a bet. The formula is MDF = 1 – (bet size / (pot size + bet size)).
When You Might Hear Or Use The Term MDF
Players often discuss MDF in situations where they are facing a bet and need to decide whether to call or fold based on the bet size relative to the pot. It’s a common topic in strategy discussions, especially when analyzing hand ranges and opponent tendencies.
In-Game Example
Imagine you’re facing a river bet in a cash game. The pot is $100, and your opponent bets $50. Using the MDF formula, you calculate that you should defend at least 67% of your range (MDF = 1 – (50 / (100 + 50)) = 0.67) to prevent being exploited by bluffs.
Strategy / Tips
- Best Practice: Use MDF to maintain balanced defense frequencies, ensuring you’re not too easily exploited by aggressive players.
- Common Mistake: Ignoring MDF calculations and consistently folding too often, allowing opponents to bluff profitably.
- Pro Tips: Adjust your MDF based on opponent tendencies; against tighter players, you might defend less, while against aggressive opponents, you might need to defend more.
