Applying Minimum Defense Frequency

#1 September 26th, 2019, 6:17 PM

So I'm practicing playing against a poker AI called Alfie that plays a near optimal strategy and realized I have a major leak with overfolding to bets higher than 75% pot. And I realized it might be best to call sometimes...

This led me to coming up with the idea of weighing my decision to call with the pot odds somehow, and I discovered that this is an existing concept called minimum defence frequency.

My question is how do I correctly apply this?

At the moment my solution is to count not only my outs, but to start counting outs that I know will make a strong bluff as well. Ie: I basically count outs for my range rather than my hand and this drastically improves my pot odds.

However I don't know if this is the right approach nor what the proper way to use MDF is. I keep reading this concept is a high hanging fruit that won't provide much benefit, but it seems to be a major leak when facing chronic flop overbettors. How much of an improvement to winrate does implementing MDF really provide?

You often only use the concept in theory to get a better understanding of what type of ranges you should use to defend with.

Most human players are so unbalanced themselves that you should use different methods/strategies to not get exploited. By reading them better than they read you.

Thanks, this is great. Going over Doug's reasons not to use MDF I can't help but wonder if I should still be using them against a constantly bluffing overbettor, or somone who uses large cbet sizes. Imagine a player who just bets 90% pot on every single wet flop that comes up. Should I not float and/or use MDF occasionally? If I just use pot odds everytime I will have to fold everytime somone bets and will only call with made hands.

Or is that basically what I should be doing?
