Villains 2/3 PSB= $0.21 , total pot=($0.53)

then we will be getting odds of 2:1
It's more like 2/5 PSB.

21/53 ~= 40% PSB = 2/5 PSB


2/5 PSB = 2/(2 + 2 + 5) = 2/9 ~= 22.2%

Just to show it works,

21 / ( 21 + 21 + 53) = 21/95 ~= 22.1%

Only off by 0.1% with the quick and easy way.



Note: always include the value of your call in the total pot for this calc.
