dunno

.27*.5*4 = .54
.5*.73*-2 = -.73

.8 + .54 -.73 = .61

Using fold% as .5, your equation for the expectation of a shove is right. Looks like you just made a silly mistake at the end there.

Ok, now we have the ev of a shove. But you didnt want that. We want to know our equity given that villain folds F% of the time. So, this is a little trickier.

EV = PF + .... blah blah blah. Make ev 0, and keep E as E. Now rearrange the equation so we get E = ...., which will give you what you wanted to know.

Even better, keep F as F, and still solve for E, then you can get E as a function of F, meaning we can plug in different Fs and get what E we need.

Even better, rearrange that last equation so that F is a function of E instead, as we'll generally know E more often than F.
