ok gonna start small and to keep things simple i'm gonna assume that our bet will be a shove.
pot =2
bet=2
P+B=4
eq=27
vill fold=40%
pf=.8

been reading that thread so i will try to solve for how much we win if he calls and we win but i'm not even sure if i remember the order of operation.

e(1-f)
e(.5)
.27(.5)=.14
Is that correct?
villain calls and he wins.

(1-.5)(1-.27)
(.5)(.73) =.37
is that correct?
trying to put it all together
EV = PF + E(1-F)(P+B) + (1-F)(1-E)(-B)
EV = .8 + .27(.5)(4) + (.5)(.73)(-2)
2.14+-.74
=
Is this correct-1.4
