Great stuff Josh

One question

On hand example 1 "picking off a river bet" you say we use additive inverse of the probability of the probablility that he doesn't have a club.

Isn't it the complement?

That's the one...[37:36]...1-chance of having any clubs

I'm no mathematician (so I'm very happy to be wrong) but I thought that additive inverse is the opposite of a number (so additive inverse of 5 is -5...when they're added together = 0).

Whereas complement quantifies something in terms of what it is not. So the chance of something not being the case = 1 - chance of it being the case.

If I'm wrong (>90%) I look like a nit-picking dickhead who is wrong...if I'm right (<10%) I still look like a nit-picking dickhead so the EV of my post is questionable!

About that bluffing turn and the river hand example, is the net when we bluff the river successfully supposed to be $130 instead of $90 (there was $50 in the pot on the turn, we bet $40 and the villain calls, so its $130) or it must be only the amount of villains $s?

btw, these are great series!

I have a question about ev calcultation (43:47 min): We bet 40$ to a 50$ pot, if villain call, we lose 40$ but if he fold we win a 90$ pot, right?
So EV=0.40*90+0.60*(-40)??

Well, if folds you've technically only won $50. You've invested $40, and gained $90 for a net of only $50. I think you're slightly confusing the situation where villain bets the river, and the situation where we bet the river. Here are 2 examples that'll hopefully make it more clear:

Our stack: $40
The pot: $50

- Let's say villain bets $40 into the $50 pot. If we lose, we have $0 (40 less than when we started). If we win, we have $130 (our original 40 + his 40 + pot of 50). We're left with $90 more than we started. So we're risking 40 to net 90.

- Now the example when we bluff $40 into the $50 pot. When we lose, we still have $0, which is -$40 from where we started. No difference here. The difference comes when villain folds and we win. Since he's folded we don't get his stack. We only get the $50 in the pot and our original $40 back. Our final stack will be $90, for a net of only $50. In this case we're risking 40 to net 50.

The basically conclusion of this is that under almost all circumstances circumstances, a bluff attempt needs to succeed a higher % of the time than an attempt to call a bluff.
