# Thread: Help required understanding a basic poker math equation

1. ## Help required understanding a basic poker math equation

Here are two sets of equations to calculate separate things:

How often a pot-size bluff has to work to be profitable
0 = 100F – (size of bet)(1-F)
0 = 100F – 100(1-F)
0 = 100F – 100 + 100F
100 = 200F 100/200 = F
.5 = F 50% of the time or more

How often a half-pot bluff has to work to be profitable
0 = 100F – (size of bet)(1-F)
0 = 100F – 50(1-F)
0 = 100F – 50 + 50F
50 = 150F 50/150 = F
.33 = F 33% of the time or more

Could someone explain to me how I need to interpret this?

"F" is "how often a half-pot bluff has to work to be profitable" and the other variable is "size of bet

The first one says that if the bet (of whatever monetary units you are using) is 100 then "half pot bet" (a bet of 50) must work 50% of the time in order to be successful.
But if the bet is only 50, then the "half pot bet" (a bet of 25) only has to work 1/3 of the time (that's actually 33.33333.... %) in order to be successful.
