Poker Draws: Flush Draws, Open-Enders, and Gutshots
Short version: a draw means you are one or two specific cards away from a stronger made hand. Beginners meet flush draws, open-ended straight draws (OESD), gutshots, and their combos first; later you separate front-door vs backdoor and clean vs dirty outs. This page focuses on naming the draw and counting outs. Turning outs into equity and comparing to pot price lives on the odds & pot odds guide. Percentages match that page's combinatorics style. Examples are hypothetical / for illustration.
What a draw is: not made yet, but “on the way”
After the flop (three community cards), you are often in one of three states:
- Made hand: you already have a pair, two pair, trips, and so on.
- Draw: specific cards would upgrade you into a flush, straight, or better.
- Air: neither a useful made hand nor a clear draw.
A draw is a situation label, not a hand-ranking category. Say whether you are drawing to a flush or a straight. Rankings: hand rankings.
Flush draw
Definition: you already see four cards of one suit; any fifth of that suit completes a flush.
Hypothetical: hole cards A♥ 5♥, flop K♥ 9♥ 2♣ — four hearts, needing one more heart.
- Outs: usually 9 (13 of the suit − 4 already visible).
- Turn → river: 9/46 ≈ 19.6%.
- Flop → river: about 35.0% (exact form: 1 − C(38,2)/C(47,2)).
With two suited hole cards, flopping exactly a flush draw (two matching board suits) is far more common than flopping a made flush. That is why you learn to price draws instead of calling every time you see four to a flush. More math: odds guide; leak list: beginner mistakes.
Open-ended straight draw (OESD)
Definition: four connected ranks; either end completes a straight.
Hypothetical: 9♠ 8♦ on a 7♣ 6♥ 2♠ flop — a 5 or a 10 makes the straight.
- Outs: usually 8 (four fives + four tens).
- Turn → river: 8/46 ≈ 17.4%.
- Flop → river: about 31.5%.
An OESD is the healthier straight draw versus a gutshot. If one end also completes someone else's flush, mark that out as dirty (below).
Gutshot (inside straight draw)
Definition: the straight is missing one interior rank; only that rank completes it.
Hypothetical: 9♠ 8♦ on J♣ 7♥ 2♠ — only a 10 makes 7-8-9-10-J.
- Outs: usually 4.
- Turn → river: 4/46 ≈ 8.7%.
- Flop → river: about 16.5%.
Gutshots need a better price (or extra equity from a pair / backdoor flush) before they are automatic calls. Do not treat every “almost a straight” as eight outs.
Combo draws: flush + straight
When you draw to both a flush and a straight, add outs then subtract overlaps (a card that completes both counts once).
| Combo | Typical outs | Flop → river ≈ |
|---|---|---|
| Flush draw + OESD | 15 (9+8−2) | ~54.1% |
| Flush draw + gutshot | 12 (9+4−1) | ~45.0% |
Hypothetical: 9♥ 8♥ on 7♥ 6♣ 2♥ — flush draw + OESD. That structure is a classic semi-bluff candidate: real equity if called, plus fold equity when you bet. See bluffing basics.
Backdoor draws
Front-door: already four to the flush (or a clear four-card straight draw) on the flop.
Backdoor: only three to a flush, or a scattered straight shape that needs both remaining streets.
Backdoor flush equity is much lower than a nine-out front-door flush draw. Treat it as a small bonus, not a reason to call large bets by itself. Master 4 / 8 / 9-out front-door counts first.
Dirty outs: completing may still lose
- Your straight-completing card also completes a board flush that opponents may already have.
- You complete a low flush and still lose to a higher flush.
- The board pairs and your flush loses to a full house.
Discount or remove those outs when counting. After you hit, ask who has the nuts: nuts guide.

| Flush + gutshot | 12 | 26.1% | 45.0% | 24% / 48% (×4 a bit high) |
| Flush + OESD | 15 | 32.6% | 54.1% | 30% / 60% (×4 needs correction) |
Rule-of-thumb error and pot-odds comparisons belong on the odds page. Use this table only to label the draw quickly.
Do not confuse “already paired” with “only a draw”
- Made + draw: top pair plus a flush draw — showdown value now and upgrade paths.
- Draw only: no pair yet; you need the next card to complete.
Betting reasons differ. The first can lean value or protection; the second is more often a semi-bluff or a priced call/fold. Clear labels make reviews honest.
Hypothetical: A♠ T♠ on A♥ 9♠ 2♦ — main label is top pair; backdoor flush is only a small add-on, not a nine-out front-door flush draw.
Read the board: others may be drawing too
- Three-flush boards: many hands already have a flush or a flush draw.
- Connected boards (9-8-7): OESDs and gutshots everywhere.
- Paired boards: flush drawers must fear full houses.
The same nine outs feel safer on a dry board than on a wet multiway board. Name your draw, then ask whether completing is still the nuts. Suited connectors and suited broadway flop more combo draws than random offsuit trash — starting-hand context: starting hands.
After you spot a draw: three steps
- Name it: flush, OESD, gutshot, or combo?
- Count outs: whole numbers; subtract overlaps and dirty outs.
- Compare price: estimate completion %, compare to equity needed to call; if short, fold or switch to a semi-bluff plan instead of calling down passively.

FAQ
What does “draw” mean in poker?
A draw means your hand is not the target category yet, but one (or two) specific cards would complete it. Four cards to a flush is a flush draw; four cards to a straight is a straight draw.
How many outs does a flush draw have?
A standard flush draw (four of a suit already visible) usually has 9 outs (13 of that suit minus the 4 you see). Turn to river is about 9/46 ≈ 19.6%; flop to river is about 35%.
What is the difference between an open-ender and a gutshot?
An open-ended straight draw (OESD) can complete on either end — usually 8 outs. A gutshot (inside straight draw) needs one specific rank — usually 4 outs. An OESD has roughly twice the completing cards of a gutshot.
What is a backdoor draw?
On the flop you only have three to a flush, or a loose straight shape that needs both turn and river to help. That is a backdoor draw. Equity is far lower than a front-door (already four to) draw — treat it as a small bonus.
Must I always call with a draw?
No. Compare your chance of completing with the equity you need to call. Example: a turn flush draw facing a half-pot bet needs about 25% equity to break even in chip terms, while 9/46 ≈ 19.6% is often short for that street alone. See the odds page for the method.
How many outs does a flush draw plus an open-ender have?
Add then subtract overlaps: flush 9 + OESD 8, minus the cards that complete both (often 2) → usually 15 outs. Flop-to-river completion is about 54%.
If my draw hits, am I always best?
Not always. A small flush can lose to a bigger flush; a straight can lose to a flush or a higher straight. After you hit, re-check who has the nuts — see the nuts page.
What should I read next after learning draws?
First get types and outs clear, then open the outs / rule-of-2-and-4 / pot-odds guide so “I have a draw” becomes “is this call priced correctly?”
