Re: Trying to become more mathy. Is this the right way to calc EV?
Here are two examples.
You have AA preflop. You bet, opponent goes all in for $50, you call. Opponent shows JJ. There is now $100 in the pot, you will win 80% of the time, so your EV is $80.
You have AA. You bet $10, opponent calls. The flop is A85 with two spades. You bet $20, opponent goes all in for $20 more. You are certain that he has a flush draw.
If you call, the pot will be $100 and you'll be 65% to win, so your EV is $65. If you play this hand a million times, your average winnings will be $65.
Ignoring the money that you already put in provides numbers that are useless. In the flush draw situation, your original formula would be (65% x $50) = $37.50. The number 37.5 has nothing to do with anything in this hand.
