      Hi,

      I wondering if there is a basic (as in "for idiots") guide to calculating EV in addition to some "live" examples?

      My first poker playing month has seen me make some very fishy plays (sure to continue into the future, no doubt), but now I'm getting my head around playing for value. So a basic example of EV and how it's used at the table would be great.

      Cheers,

      Hello!

      The basic information about the Expected value (EV) can be found at this page in glossary.

      Hello to you to!

      Thanks for the help, I was wondering if there were any examples of hands played where the EV is explained step-by-step? I understand the principles using the coin toss, but trying to understand it with value betting is a tad difficult...

      Thanks

      Hi Helipacter,

      So two examples:
      We are on the turn and the pot is $100. You have 1/3 equity. The player bets all-in which is half pot ($50). How much is your EV, if you call?
      EV = $150 * 33% - $50 * 67% = $16.67.

      So with every call you win $16,67.

      Same example, but the player bets all-in now with $100.
      EV = $200 * 33% - $100 * 67% = $0.

      If you have further questions do not hesitate to ask.

      Best regards,
      Hannes

      General guide for all kind of EV calculations:

      Expected value = probability of a win * how much you make when you win -
      probability of a loss * how much you "donate" when you loose.
