Outs

What Is an Out?

An out is any card left in the deck that completes your draw or improves your hand to a likely winner. Counting outs is the first step in calculating your pot odds and determining whether to continue in a hand. Before you can assess whether a call is profitable, you need to know how many cards help you.

The concept is intuitive. If you hold four hearts after the flop and need one more for a flush, there are 9 remaining hearts in the deck. Those 9 hearts are your outs. The more outs you have, the better your chances of improving, and the more liberally you can call or raise.

Accurate out counting also requires honest assessment. Not every card that completes your draw necessarily wins you the hand. If you are drawing to a flush but the board pairs, someone might hold a full house. These considerations lead to the concept of “clean outs” versus “dirty outs” and “discounted outs,” refinements that separate beginners from experienced players.

How It Works

Counting Outs:

After the flop, there are 47 unseen cards (52 minus your 2 hole cards and 3 board cards). After the turn, there are 46 unseen cards. Your outs are the subset of those cards that make your hand a likely winner.

Common Draw Scenarios:

| Draw | Outs | Example |

|—|—|—|

| Flush draw | 9 | You hold two hearts, two on board |

| Open-ended straight draw (OESD) | 8 | You hold 7-8 on a 5-6-K board |

| Gutshot straight draw | 4 | You hold 7-8 on a 5-9-K board (need a 6) |

| Two overcards | 6 | You hold A-K on a 7-8-2 board |

| Flush draw + gutshot | 12 | Combination draw |

| Flush draw + OESD | 15 | Monster draw |

| Set to full house/quads | 7 | You hold a set on a two-tone board |

| One pair to two pair/trips | 5 | You hold top pair, need to improve |

| Two pair to full house | 4 | You hold two pair on a dangerous board |

The Rule of 2 and 4:

The rule of 2 and 4 estimates the chance of hitting counted outs. It does not by itself calculate equity against a range: a hit can still lose, and an unimproved hand can sometimes win.

After the flop (two cards to come): Multiply outs by 4.

After the turn (one card to come): Multiply outs by 2.

Examples:

• 9 outs on the flop: 9 x 4 = 36% (exact: 35%)
• 9 outs on the turn: 9 x 2 = 18% (exact: 19.6%)
• 15 outs on the flop: 15 x 4 = 60% (exact: 54.1%)

For draws with more than 8 outs, the Rule of 4 slightly overestimates. You can subtract 1% for every out above 8 for more accuracy. So 15 outs: 15 x 4 – 7 = 53%, closer to the exact 54.1%.

Discounting Outs:

Not all outs are created equal. Sometimes a card that completes your draw also completes a better hand for your opponent.

Consider 8s 9s on the flop 7s Ts Ad, before either remaining board card is dealt. The Sixes and Jacks give eight immediate straight-completing cards. In particular, 6s makes 6s-7s-8s-9s-Ts, and Js makes 7s-8s-9s-Ts-Js: both are straight flushes. Keep those two outs. Do not discount them merely because someone could make an ordinary flush. Other completions may still need a separate redraw assessment.

Example

You are playing $1/$2 and hold Qh Jh. The flop comes Th 4h 9c. You have a flush draw (9 outs) and an open-ended straight draw needing a K or 8 (6 additional outs since Kh and 8h are already counted in the flush draw).

There are 15 distinct cards that complete a flush or straight on the next card under that count. The shortcut 15 x 4 = 60% overstates the probability of hitting one of those cards over two draws: 1 – (32/47 x 31/46) = 54.12%. Neither number establishes your equity against a specified opponent.

If an opponent may hold Ah Xh, do not subtract an arbitrary two or three outs. Some heart completions can lose to a higher flush, and known opposing cards change the unseen-card count. Specify the hand or range and check each outcome. Compare that equity with the call price, C / (P + C), using P including the opponent’s bet; without a price, no percentage is enough to justify a call.

Common Mistakes

• Counting outs that do not actually win the hand, such as drawing to a non-nut flush when the nut flush draw is likely out there
• Forgetting that the same card can count for multiple draws and double-counting outs already included
• Using the Rule of 4 when facing a bet where you will only see one more card (should use Rule of 2 unless you are guaranteed to see both turn and river)
• Not discounting outs against opponents who likely hold hands that reduce your clean outs

FAQ

What is the difference between outs and equity?

Outs count candidate improving cards; equity is your expected share of the pot against a hand or range, including ties. With nine winning outs and 46 unseen cards, the next-card hit probability is 9/46 = 19.57%. It equals win probability only under the stated winning-out assumptions.

Should I always count outs the same way in multi-way pots?

In multi-way pots, discount your outs more aggressively. With multiple opponents, the chance that one of them holds a hand that blocks or beats your draw increases. A flush draw against one opponent might be 9 clean outs, but against three opponents, some of those flush outs may already be in their hands, and your completed flush might lose to a higher flush.
