formula help

I am trying to learn how to calculate EV. Does anyone know the formula for calculating this. Also is there a ebook with the different poker math out there that I could get. Thanks for the help

EV or equity?

I would take the answer to both but I was actually looking at ev

Well equity is easy, you take the number of cards that will complete your hand and divide it by the number of cards in the deck. With two cards to come you can generally double this number.

EV is much harder, when trying to calculate EV you have to factor in your opponents hand, the amount of their/your bet, the size of the pot, and your hand. Basically with EV you are trying to determine if the play you make (calling, folding, raising, etc...) shows a positive expectation when made. EV can mean many things, sometimes it means determining if a bluff will win you the pot enough times to be correct, or if your opponent will call a valuebet with worse hands enough to be for "value" or if you have a flush draw and your opponent bets a certain amount will calling be +EV.

I'll need some more concrete examples to show you how to calculate your EV in spots.

I already know how to calculate pot odds and I understand how to calculate outs. After reading your post how important is it to be able to calculate EV in your head at the table. I use pot odds and implied odds to make my decisions. If I am getting 5 to 1 on my money and i put the other person on a big hand. providing i am not shortstacked. this is what i use to make my calls. SO my question is if you can do this in your hand and you understand pot odds and implied odds and stack to port ratio how important is it to be able to calculate ev in your head. I guesse like you said in the last post I just need some good examples. Thanks for any clarity any one can give me on this.

Thanks

Take a quick look at Erpels homework assignment thread, I asked the same question and got a great answer from overflow, it writes out the formula in great clarity.

I think it's more important after you are done with your session and reviewing your HH's to understand if your play in a certain spot was +EV or not and why.
