MDF (Minimum Defense Frequency)
MDF（最低防守频率）
Minimum Defense Frequency (MDF) is a GTO concept that calculates how much of your range you need to continue with (call or raise) to make your opponent's bluffs indifferent. MDF = pot / (pot + bet size). If opponent bets pot on the river, MDF = 50%, meaning you must defend at least 50% of your range.
Example
Pot is 100 and opponent bets 50. MDF = 100/(100+50) = 66.7%. You must defend at least 2/3 of your range.
