What are Poker Odds?
Poker odds represent the mathematical probability of making your hand or winning the pot. Understanding odds is essential for making profitable decisions at the poker table. Your "outs" are cards that improve your hand, and calculating the probability of hitting those outs determines whether calling a bet is mathematically correct.
Outs to Odds Conversion Formula
Win Probability = (Outs / Cards Remaining) x 100
Where:
- Outs = Number of cards that improve your hand
- Cards Remaining = 47 after flop, 46 after turn
- Odds Against = (Cards Remaining - Outs) : Outs
Example: With 9 outs on the turn, Win Probability = (9 / 46) x 100 = 19.6% or roughly 4:1 odds against you
Common Poker Draws and Outs
Flush Draw
Outs: 9 cards
Flop to River: ~35% chance
Turn to River: ~19.6% chance
4 cards to a flush - need one more of your suit to complete
Open-Ended Straight Draw
Outs: 8 cards
Flop to River: ~32% chance
Turn to River: ~17.4% chance
Four cards in sequence - need card on either end to complete
Flush + Straight Combo
Outs: 15 cards
Flop to River: ~54% chance
Turn to River: ~32.6% chance
The monster draw - flush draw + open-ended straight draw combined
Understanding Poker Variance
Short-Term Variance
Even with 80% equity, you'll lose 20% of the time. Variance means correct decisions can lose in the short run. Focus on making +EV decisions, not results of individual hands.
Overestimating Outs
Not all outs are "clean." If your flush completes but makes a full house possible, your out count may be misleading. Consider opponent ranges and board texture.
Ignoring Implied Odds
Pot odds only consider current money in the pot. Implied odds factor in potential future bets if you hit. Drawing hands gain value in deep-stack situations.
Reverse Implied Odds
Sometimes hitting your draw costs you more money. Drawing to weak flushes or bottom straights can lead to second-best hands that lose big pots.
Real-World Poker Odds Calculations
Example 1: Flush Draw on Turn
Situation: You have A♥ K♥, board is Q♥ J♥ 7♠ 2♣
Outs: 9 remaining hearts
Calculation: 9/46 = 19.6%
Odds: 3.1:1 against (call if pot odds better than 3.1:1)
Example 2: Open-Ended Straight After Flop
Situation: You have 9-8, flop is 7-6-2 rainbow
Outs: 8 cards (four 5s, four 10s)
Calculation: (1 - (39/47 x 38/46)) = 31.5%
Odds: 2.2:1 against making straight by river
Example 3: Gutshot with Overcards
Situation: You have A-K, flop is Q-J-4 rainbow
Outs: 4 tens (gutshot) + 6 aces/kings = 10 outs
Calculation: (1 - (37/47 x 36/46)) = 38.4%
Decision: Strong draw, profitable against most bet sizes
Professional Poker Odds Tips
Master the Rule of 2 and 4
Multiply outs by 4 after the flop (two cards coming) or by 2 after the turn (one card coming). This gives you a quick approximation percentage for decision-making at the table.
Discount Your Outs
Not all outs are clean. If your flush card also completes a straight or pairs the board, reduce your out count by 1-2 cards to account for situations where you improve but still lose.
Consider Position
Drawing hands play better in position. You get to see if your opponent bets again before deciding to call, and you can realize equity more effectively when you act last.
Use Pot Odds, Not Hope
Always compare your winning percentage to the pot odds being offered. If you need 25% equity to call and have 30%, it's a profitable call regardless of the result.
Factor Stack Sizes
With deep stacks, implied odds make drawing more profitable. You can win multiple bets if you hit. With short stacks, pot odds matter more since there's no money behind to win.
Track Your Results
Review hands where you made drawing decisions based on odds. Over thousands of hands, your results should align with the mathematics if you're calculating correctly.
Frequently Asked Questions
What are poker outs and how do I count them?
Outs are cards that will improve your hand to likely win the pot. For a flush draw, you have 9 outs (remaining cards of your suit). For an open-ended straight draw, you have 8 outs. Count each card that completes your draw, but avoid counting the same card twice if it helps in multiple ways.
What is the Rule of 2 and 4 in poker?
The Rule of 2 and 4 is a quick mental shortcut for calculating poker odds. After the flop, multiply your outs by 4 to estimate your percentage chance to hit by the river. After the turn, multiply your outs by 2 to estimate your chance to hit on the river. This gives you a close approximation for quick decisions.
How do I calculate pot odds?
Pot odds are calculated by dividing the amount you need to call by the total pot size after your call. For example, if the pot is $100 and your opponent bets $20, you need to call $20 to win $120, giving you pot odds of 20:120 or roughly 1:6 (16.7%). Compare this to your chance of winning to determine if calling is profitable.
Should I call if my pot odds are better than my hand odds?
Yes, you should call when your pot odds are better than your hand odds. If you need to call $20 to win $120 (16.7% pot odds) and you have a 20% chance to win, this is a profitable call in the long run. The difference between your win probability and required pot odds is your edge.
What is a flush draw in poker?
A flush draw is when you have four cards of the same suit and need one more to complete a flush. With 13 cards of each suit in the deck and 4 already visible, you have 9 outs (remaining cards of your suit). A flush draw has approximately 35% chance to complete from flop to river.
What are implied odds in poker?
Implied odds consider potential future bets you might win if you hit your draw, not just the current pot size. If you expect your opponent to call a large bet when you complete your flush, your actual odds are better than the current pot odds suggest. This makes drawing hands more valuable in deep-stack situations.
