Why Poker Odds Matter
Understanding poker odds and probabilities is crucial for making mathematically correct decisions. While poker involves luck, the best players use odds to minimize losses and maximize winnings over time.
🎯 Expected Value (EV)
The average amount you can expect to win or lose on a decision over many repetitions.
💰 Pot Odds
The ratio of money in the pot compared to the amount you need to call.
🎪 Implied Odds
Future bets you expect to win if you hit your hand.
Basic Poker Probabilities
How to Calculate Pot Odds
Pot odds help you determine if a call is mathematically correct.
Example 1: Simple Pot Odds
Pot: $100
You need to call: $20
Pot Odds = $100:$20 = 5:1
If your equity is better than 16.7% (1/6), the call is profitable.
Example 2: With Multiple Callers
Pot: $150
You need to call: $30
Pot Odds = $150:$30 = 5:1
Same 16.7% break-even point.

Expected Value Examples
Coin Flip Situation
You have 50% equity. Pot: $200. Call: $100.
EV = (0.5 × $200) + (0.5 × -$100) = $50
Expected profit of $50 per decision.
Bluff Example
You bluff with 20% equity. Pot: $100. Bet: $50.
EV = (0.2 × $150) + (0.8 × -$50) = -$10
Expected loss of $10 - bad bluff!
Poker Odds Calculator Tips
🎯 Break-Even Percentage
Convert odds to percentage: 3:1 = 25% (you need 25% equity to break even).
💰 Implied Odds
Factor in future streets. If you'll win $200 more when you hit, your effective odds improve.
📊 Reverse Implied Odds
When hitting your hand might cost you more money later (like drawing to a flush with many suited cards on board).
🃏 Hand Reading
Use odds to narrow opponent ranges. If they always fold to aggression, you can bluff more.
