Equity

[springb0ks]

Guys, what would a good equity value be, in order to make a call to someone who has moved all in or something? How does one deduce that the call is correct based on the equity?

Thanks

An easy way to calculate your equity in a situation is the following:

(% equity)*(pot size)

For instance, Johnny holds a hand on the flop that gives him 75% equity. In other words, the pot is 75% his, he wins it 75% of the time (longrun styles). The pot is 200 dollars.

(.75)*($200)=$150

Johnny's pot equity is $150.

On the turn, Johnny's equity remains the same, and his opponent makes a $100 dollar bet. Since Johnny's equity is greater than the bet, he is getting good value for his money. He will call.

If the opponent made a $200 bet, Johnny would fold, as the play would no longer be profitable.


Hope this helped.

And phzon, feel free to correct me if I'm wrong.

Sorry, this is wrong. The size of the pot to use is the size after a call. That would be

$200 initial pot +
$200 bet +
$200 call
=
$600.

If you win $600 75% of the time, your share is $450, which is much greater than the $200 cost of the call. When you are the favorite heads-up, you can call any amount all-in, since your share of the new pot will always be larger than the amount of your call.

Thanks for correcting, pzhon.
