Sorry to have left you hanging, acg. I was spending all my time in the "Werewolf Village" forum here on FTR.
My team lost 'cause I made a couple of really bad choices.

***
Renton has lead you well, and the only critique I have for him is semantic.
He used "EV" when he should have use "value" a couple of times.
Here's what he wrote:
EV(3-bet) = P(fold)*EV(fold) + P(4-bet)*EV(4-bet) + P(call)*EV(call)

It should be:
EV(3-bet) = P(fold)*V(fold) + P(4-bet)*V(4-bet) + P(call)*V(call)

I just took the E's out of the RHS (right-hand side) of the equation. This is because we know the value of that play, and it's not a random variable.

I.e. If we bet, and Villain folds, we will win a non-random amount. That is a value.
When we multiply that value by a rate at which Villain folds, that's an expected value.
