Hello guys, i know maybe this is the 1000th time you hear such a question but i m a beginner , could anyone explain me in a simple way what +/-Ev refers to? and how it can affect my game?
I'm a beginner too - only a few hundred thousands of hands under my belt. EV stands for expected value. +EV is when your hand has more chance to win than it does to lose. When you're making -EV plays, you need to suck out in order to win. Give these articles a read through they explain a lot about odds and equity, and they explain it all very simply.
Expected value; how much profit/loss you can expect as a result of your action. When thinking of expected value think long-term as if variance doesn't exist.
Easy example.
You fold preflop before putting any money in the pot. Expected value is zero. Your action of a fold will result in no profit or loss.
0% chance of winning any money
* Amount of money you can win
= ZERO EV!
expected value... (in the long term) its hard for new players to understand this because you have to thinkin the long term not in the short term... u take a play you made...lets say a call for a draw... theres 50$ in the pot you call 20$ all in bet on the turn to hit a flush on the river and win... most players look at the short term they won and its a good call right.... ev would be looking at the long term...if you made that same exact move 10 times what would be your profit after ten times..... lets see you 8 times you would miss your flush and lose (20 x 8 = -160) two times you would hit your flush and win the pot ( 50+20) x 2= 140 so your expected value (how much you expect to win after 10 times of playing that way) is -160+140= -20.... so that decision will lose you 20$ every ten times you make that call..... what makes this hard to understand is when you make that call and win a 70$ pot and someone tells you that YOU JUST LOST MONEY...hard for new players to understand how they can win a pot and LOSE money... basically +EV means your decision will make you money in the LONG run... -EV means that decision will lose you money in the LONG run....
