Expected Value (EV) in Poker

Expected Value (EV) is the foundation of winning poker. Every profitable decision in Texas Hold’em is based on EV.

If a play makes money in the long run, it is +EV. If it loses money long term, it is −EV.

What Is Expected Value?

Expected Value is the average amount you expect to win or lose if a situation were repeated many times.

EV = (Probability of Winning × Amount Won) − (Probability of Losing × Amount Lost)

Simple EV Example

Suppose:

• You call $50
• You win $150 total pot
• You win 40% of the time
• You lose 60% of the time

EV = (0.40 × 150) − (0.60 × 50)

EV = 60 − 30 = +$30

That means this call earns $30 on average every time you face this spot.

+EV vs −EV

• +EV = Profitable long term
• 0 EV = Break-even
• −EV = Losing long term

Winning players consistently choose +EV decisions.

EV and Equity

Equity tells you your chance of winning. EV tells you whether acting on that equity is profitable.

EV and Pot Odds

Pot odds determine the minimum equity required to make a call +EV.

EV with Fold Equity

When betting or shoving, EV becomes:

EV = (Fold % × Pot) + (Call % × (Equity × Total Pot − Risk))

This is why aggressive plays can be profitable even with weaker hands.

All-In EV Example

You shove $100 into a $100 pot. Opponent folds 30% of the time. You have 45% equity when called.

Your EV includes:

• Immediate win from folds
• Showdown equity when called

Many tournament decisions depend on correctly calculating all-in EV.

Why EV Is the Backbone of Poker

• Removes emotion from decisions
• Defines correct strategy mathematically
• Explains variance
• Separates professionals from recreational players
