A gutshot straight draw needs one specific card in the middle to make a straight. It has four outs, about 16.5% to hit by the river from the flop, and it’s one of the most misplayed draws in poker.
Some players chase every gutshot at any price. Others fold them in spots where a well-timed bet would win the pot. Both cost money.
This guide covers the math, which gutshots are worth playing, how dirty outs and double gutshots change things, and how to play gutshots as the preflop raiser and as the defender in Texas Hold’em.
What Is a Gutshot Straight Draw?
A gutshot, also called an inside straight draw, is a straight draw that only one rank can complete.
Holding 7-6 on K-4-3, you need a five. Holding A-7 on Q-J-10, you need a king. Either way, four cards in the deck make your straight, which ranks above three of a kind in the poker hands order.
Compare that with an open-ended straight draw, like 6-5 on K-4-3, where a seven or a deuce completes it. Two ranks means eight outs, so the open-ender hits about twice as often.
The Math Behind Gutshot Straight Draws
With four outs, these are your odds.
| Situation | Chance to make the straight |
|---|---|
| Flop, with the turn and river to come | about 16.5% |
| Flop or turn, with one card to come | about 8.5% |
The rule of 4 and 2 gets you close. Four outs times 4 is 16% on the flop, and four times 2 is 8% on the turn.
Your real equity is often a little higher. With 7-6 of hearts against pocket aces on K-4-3, you have about 18.7%, because runner-runner pairs, two pairs, and backdoor draws add a bit.
That math is why a naked gutshot rarely has the pot odds to call a big bet. Facing a half-pot bet, you need about 25% equity, and a gutshot on the turn has about 8.5%. Calling needs extra equity or strong implied odds against an opponent who will pay you off.
Good vs Bad Gutshots
A gutshot is only as good as the straight it makes and the extra equity that comes with it. These five flops show the range.
- T♠9♠ on 7♠6♥2♦. One of the best. Two overcards, a backdoor flush draw, and any eight makes the nut straight. Play it aggressively.
- A♥5♥ on K♥J♠T♠. A gutshot to the nuts with a queen, plus a backdoor flush draw and an ace that blocks strong hands. A good bluffing hand, though a queen often splits the pot with any other ace.
- 4♠3♠ on Q♠7♣6♥. A five makes a straight, but not the nuts, and the backdoor flush is weak. Usually a fold to a bet.
- 6♣5♦ on K♣9♠8♠. A seven makes only the bottom straight, with no backdoor flush and two undercards. An easy fold most of the time.
- 9♥8♥ on K♦Q♦J♠. A ten makes a straight that loses to any ace. The weakest of the five.
The difference between the best and the worst is enormous. Before you bet or call, check whether your gutshot draws to the nuts and what else your hand has going for it.
Dirty Outs
A dirty out completes your straight but can still lose. There are three kinds.
- Flush-completing outs. On a two-tone board, the out that matches the suit completes a flush for anyone on a flush draw.
- Board-pairing outs. If your card pairs the board, an opponent with a set or two pair can make a full house.
- Straight-over-straight outs. If you’re drawing to a low straight, your card can give someone a bigger one.
On a two-tone board, count one of your four outs as risky and work out your odds as if you had three.
Double Gutshots
A double gutshot needs one of two ranks, each filling a gap. It has eight outs, the same as an open-ender, but it’s easy to miss because it doesn’t look like a big draw.
Here’s an example. You hold J♣9♣ on K♦T♠7♥. An eight gives you 7-8-9-10-J, and a queen gives you 9-10-J-Q-K. Each is a gutshot on its own, but together they give you eight outs and about 31.5% to hit by the river from the flop.
Play a double gutshot like an open-ender. It’s a strong semi-bluffing hand as the preflop raiser, and often a good check-raise from the big blind.
Playing Gutshots in Multiway Pots
Multiway pots change gutshot strategy a lot. A bet with a gutshot needs folds, and with two or three opponents, someone usually has a hand they won’t let go of.
Play gutshots mostly as calling hands in multiway pots, and only when you have extra equity from overcards or backdoor draws, or when you’re drawing to the nuts. A naked gutshot to a non-nut straight is usually a fold against any real bet.
The exception is when you raised preflop and the flop checks to you. A small continuation bet with a gutshot can still take the pot, but be ready to give up against a check-raise.
Playing Gutshots With the Initiative
When you raised preflop, a gutshot with backdoor draws is one of your best bluffing hands, because it can still improve when called.
Say you raise T♥9♥ on the button in a $2/$5 game to $15 and the big blind calls. The flop comes K♦7♥6♠ and your opponent checks. You have a gutshot to any eight, a backdoor flush draw and the initiative. Your range has all the strong kings and overpairs, while the big blind’s range has a lot of second pairs, third pairs and draws.
Bet small, around $20 into $32. If you’re called and the turn is a blank like the 2♦, a second bet of about $55 into $72 puts real pressure on all those weaker pairs and draws. You still have the gutshot when called.
The common mistake is betting the flop and giving up on the turn every time. Plan both streets before you fire the first bet.
Playing Gutshots as the Defender
From the big blind, you’ll often have a gutshot out of position. Here a check-raise is often better than a call.
Say the button raises to $15 and you defend 9♠7♠. The flop is 6♥5♦Q♠, giving you a gutshot to any eight. You check, and the button bets $10 into $32. You have the price to call, but calling and checking the turn often leaves you facing another bet with nothing.
A raise to around $45 wins the pot a lot of the time, because the button has many ace-high and king-high hands that can’t continue. And your range has hands like Q-6, Q-5 and 6-5 that the button rarely holds, so the raise is believable. If you face a re-raise, fold.
Pick check-raises where the board fits your range. With the same 9-7 on K-Q-5, you have few strong hands and a raise gets called by every king.

In my experience reviewing student hands, gutshots are misplayed more often than almost any other draw. These leaks show up the most.
- Calling big bets with a naked gutshot. Four outs needs a great price.
- Treating every gutshot the same. A nut gutshot with overcards and a backdoor flush draw is a different hand from a bottom-end gutshot with two undercards.
- Counting dirty outs as clean on two-tone and paired boards.
- Missing double gutshots and folding eight-out draws.
- Bluffing gutshots into multiway pots or into players who never fold.
Conclusion
The best gutshots to play have extra equity and draw to the nuts. Bet and check-raise them heads-up, and fold the bottom-end, no-backdoor gutshots against real bets.
With four outs, the price matters on every street. Without good pot odds or a plan to win the pot with a bet, a gutshot is usually a fold.
