Outs are the cards remaining in the deck that will improve your hand to a likely winner. If you have A♥K♥ on a Q♥J♥4♣ flop, any heart (9 outs) or any ten (4 outs) gives you a strong hand, that’s 13 outs total to hit by the river.
In poker, outs represent your mathematical lifelines when you’re behind. Each out is a specific card that, if dealt on the turn or river, transforms your current holding into what you believe will be the best hand. The concept of outs forms the foundation of poker mathematics, connecting directly to pot odds calculations and profitable decision-making. Players count their outs to determine their equity (winning percentage) in a hand.
Accurate out counting separates winning players from losing ones. While beginners might hope to “get lucky,” experienced players know exactly how many cards help them and what percentage of the time they’ll hit. This knowledge transforms poker from gambling into strategic decision-making, where every call, raise, or fold has mathematical justification.
What Are Outs in Poker?
Outs are specific cards that haven’t been dealt yet and would give you the winning hand if they appeared. The deck starts with 52 cards, minus your 2 hole cards and the visible board cards leaves the remaining unseen cards. Your outs hide among these remaining cards.
Here’s a simple scenario: You hold 7♠6♠ and the flop comes 8♦5♣K♥. You have an open-ended straight draw. Any 4 or any 9 completes your straight, that’s 8 outs (four 4s and four 9s in the deck).
The strength of your outs matters too. “Clean outs” give you the definitive best hand, while “dirty outs” might improve your hand but still lose to a better one. If you’re drawing to a flush on a paired board, your flush outs might be “dirty” because they could complete your opponent’s full house.
Common Out Counts
| Draw Type | Outs | Example |
|---|---|---|
| Gutshot Straight | 4 | A♣K♣ on Q♥T♠4♦ (need J) |
| Open-Ended Straight | 8 | 7♠6♠ on 8♦5♣K♥ (need 4 or 9) |
| Flush Draw | 9 | A♥K♥ on Q♥8♥4♦ (need any heart) |
| Flush + Gutshot | 12 | A♥T♥ on K♥Q♥4♦ (hearts + jacks) |
| Flush + OESD | 15 | 7♥6♥ on 8♥5♠4♥ (hearts + 9s + 3s*) |
| Set to Full House | 10 | 7♣7♦ on 7♥A♠K♣ (any A, K, or 7) |
*Note: 3♥ counted only once despite making both flush and straight
How to Count Outs Accurately
Counting starts with identifying exactly what hands beat you and what cards give you a winner. Write it out mentally: “I need X to make Y hand, which beats Z.”
Avoid these common counting errors:
- Double-counting: If you need a heart for a flush and specifically the 9♥ also makes a straight, it’s still just one out, not two
- Counting opponent’s outs: The A♠ might give you top pair, but if it completes your opponent’s flush draw, it’s not truly an out
- Overvaluing weak improvements: Making bottom pair when your opponent likely has top pair isn’t a real out
For flush draws, count the suited cards: 13 total of each suit, minus the ones you see. If you have two hearts and see two more on the flop, that’s 13, 4 = 9 outs.
For straight draws, list the ranks that complete your straight, then count those specific cards. Be careful with draws that need only one specific rank (gutshots = 4 outs) versus those that can use either of two ranks (open-enders = 8 outs).
Outs to Equity Conversion
The “Rule of 2 and 4” quickly converts outs to winning percentage:
- With two cards to come (on the flop): Outs × 4 = Approximate equity %
- With one card to come (on the turn): Outs × 2 = Approximate equity %
This mental shortcut stays accurate within 1-2% for most common draws:
| Outs | Flop Equity (×4) | Actual | Turn Equity (×2) | Actual |
|---|---|---|---|---|
| 4 | 16% | 16.5% | 8% | 8.7% |
| 8 | 32% | 31.5% | 16% | 17.4% |
| 9 | 36% | 35% | 18% | 19.6% |
| 12 | 48% | 45% | 24% | 26.1% |
| 15 | 60% | 54.1% | 30% | 32.6% |
Clean Outs vs Dirty Outs
Not all outs guarantee victory. Clean outs give you the clear best hand, while dirty outs improve your hand but might still lose:
Clean out example: You have A♠K♠ on J♠T♠4♦. Any spade (9 outs) gives you the nut flush, no hand beats you.
Dirty out example: You have A♥K♣ on Q♥J♥4♦. A ten gives you a straight, but if your opponent has K♥T♥, that same ten gives them a flush.
When counting outs for pot odds calculations, discount your dirty outs. If you think 3 of your 9 flush outs might give your opponent a full house, count yourself as having 6-7 clean outs instead of 9.
Hear It at the Table
“I’ve got 15 outs but half of them are dirty, any diamond makes my flush but pairs the board.” This shows advanced thinking about out quality.
Key Takeaway
Outs are your roadmap to winning when behind, count them accurately and you’ll know exactly how often you’ll catch up. Every out represents roughly 2% equity with one card to come or 4% with two cards to come. Master this fundamental concept and you’ll transform hope into mathematical certainty, making profitable decisions based on facts rather than feelings.
