🃏 What Are Outs — Counting the Cards That Win You the Pot

A draw hand hasn't made a completed hand yet, but if one specific card comes, it can pull ahead. Those cards that complete your hand are called outs.

Let's walk through a concrete example.

Let's break down the situation:

• Your opponent has top pair (Kings). You only have high card — you're losing
• But you have four spades (J♠ T♠ K♠ 6♠). One more spade completes a flush and takes the lead!
• There are 13 spades total in the deck. Four are already visible
• Remaining spades: 13 − 4 = 9

Those 9 remaining spades are your outs. If any one of them comes, you complete a flush and beat top pair.

📊 Outs by Draw Type

Here's a summary of how many outs each common draw has.

Draw Type	Outs	How to Count
Quads draw (trips → quads)	1	1 remaining card of the same rank
Set draw (pocket pair → set)	2	2 remaining cards of the same rank
One overcard	3	1 rank higher than the board × 3 remaining cards
Gutshot	4	1 missing rank × 4 cards
Two overcards	6	2 ranks higher than the board × 3 cards each
OESD (open-ended straight draw)	8	2 ranks on each end × 4 cards each
Flush draw	9	13 of the suit − 4 already visible
OESD + flush draw	15	8 + 9 − 2 overlapping cards

We already confirmed the flush draw (9 outs) in the J♠T♠ example above. Let's also see how to count OESD and gutshot outs.

OESD — 8 Outs

Gutshot — 4 Outs

⚡ The Rule of 2 and 4 — Turning Outs into Equity

Bottom line: once you know your outs, one multiplication gives you a quick equity estimate.

Situation	Cards to Come	Formula
Turn → River	1 card	Outs × 2%
Flop → River	2 cards	Outs × 4%

The memory trick is simple: one street left = × 2%, two streets left = × 4% (which is 2% × 2).

Let's apply this to our outs chart.

Draw	Outs	Turn+River ×4%	Actual	River Only ×2%	Actual
Quads draw	1	4%	4.3%	2%	2.1%
Set draw	2	8%	8.4%	4%	4.3%
One overcard	3	12%	12.5%	6%	6.4%
Gutshot	4	16%	16.5%	8%	8.5%
Two overcards	6	24%	24.1%	12%	12.8%
OESD	8	32%	31.5%	16%	17.0%
Flush draw	9	36%	35.0%	18%	19.1%
OESD + flush draw	15	60%	54.1%	30%	31.9%

The completion odds we introduced in Evaluating Your Hand on the Flop — flush draw ≈ 35%, OESD ≈ 32%, gutshot ≈ 17% — match almost perfectly. Those numbers came from this simple multiplication all along.

🔗 Combining with Pot Odds — The Complete Call Decision

Now that you can derive equity from outs, let's combine it with pot odds. The decision process is just four steps.

Step	What to Do
1	Count your outs
2	Convert outs to equity (flop → × 4%, turn → × 2%)
3	Calculate the required equity from pot odds (call amount ÷ pot after calling)
4	Compare your equity to the required equity → if your equity ≥ required equity, call ✅

Let's work through an example. You're on the turn with an OESD.

The pot is 200 chips and your opponent bets 100 chips (a 50% pot bet).

• Required equity: 100 ÷ 400 = 25%
• Your equity: 16%
• 16% < 25% → Fold ✋

You can look up the required equity instantly using the bet-size reference table. And you can get your equity from outs with mental math. Just compare the two numbers and your call decision is done.

🎓 Practice Scenarios: Outs → Equity → Call Decision

Scenario 1

The turn has been dealt.

Hand: K♠ 9♠ Board: A♠ 6♠ 4♣ T♥

The pot is 200 chips. Your opponent bets 100 chips (50% pot). Should you call?

Q1: How many outs? What is your equity? Call or fold?

See the answer

Outs: 9 — Four spades are visible (K♠ 9♠ A♠ 6♠). Remaining spades = 13 − 4 = 9.

Equity: 9 × 2% = 18% — It's the turn, so only one card to come. Use × 2%.

Required equity: 100 ÷ 400 = 25% — Call amount 100 ÷ (200 + 100 + 100) = 25%.

Fold ✋ — 18% < 25%. A flush draw is powerful, but the equity doesn't meet the threshold against a 50% pot bet.

Scenario 2

The flop has been dealt.

Hand: 8♥ 7♦ Board: 9♠ 6♣ 2♦

The pot is 100 chips. Your opponent bets 33 chips (33% pot). Should you call?

Q1: How many outs? What is your equity? Call or fold?

See the answer

Outs: 8 — You have four in a row: 6-7-8-9. A 5 (4 cards) or a T (4 cards) completes the straight = 8 outs.

Equity: 8 × 4% = 32% — It's the flop, so two cards to come. Use × 4%.

Required equity: 33 ÷ 166 ≈ 20% — Call amount 33 ÷ (100 + 33 + 33) ≈ 20%.

Call ✅ — 32% > 20%. Your equity far exceeds the required equity. Calling with an OESD against a small bet is the right play.

⚠️ Common Mistakes

1. Using the wrong multiplier for the street

A frequent error is using "outs × 4%" on the turn. The × 4% formula is the probability of completing your draw with two cards to come (flop to river). On the turn, there's only one card left, so you must use × 2%.

Let's see the difference with a flush draw (9 outs).

When You Calculate	Correct Formula	Result
Flop (2 cards to come)	9 × 4%	36%
Turn (1 card to come)	9 × 2%	18%

If you mistakenly use × 4% on the turn, you'll get 36% instead of the real 18%. Calling based on an equity estimate that's double the actual value leads to significant losses.

2. Only count outs that actually win

Even if your draw completes, your opponent might hold an even stronger hand. For example, you might complete a spade flush, but if your opponent holds A♠, they have a higher flush and you lose. Strictly speaking, you should exclude such "tainted outs" from your count. That said, as a beginner, using the theoretical out count for a quick estimate is perfectly fine. Think of it as a practical tool that keeps you from making large errors when comparing against pot odds.

🎯 Summary

You can now use outs and pot odds to decide "call when your equity exceeds the required equity." But what about when your equity falls short — should you always fold? Actually, there are spots where calling is correct because "even though it's -EV right now, completing the draw will win a huge pot from your opponent's stack." Next up, we'll learn about implied odds, which factor in the chips you stand to win on future streets.
