In poker, a gutshot refers to a specific type of straight draw where a player needs just one exact card rank to complete their straight. It is also commonly known as an "inside straight draw."
A gutshot occurs when your hand, combined with the community cards, creates a sequence with a gap in the middle, and hitting the specific card to fill that gap will complete your straight. For example, if you hold 8x7x and the flop comes Kx5x4x, you have a gutshot draw, as a 6x is the only card that will complete your straight (4x-5x-6x-7x-8x).
Understanding the Gutshot Draw
A gutshot draw is a less powerful straight draw compared to an open-ended straight draw (OESD) because it offers fewer "outs." An "out" is a card that will improve your hand to a winning one.
Key Characteristics
- Single Out: A gutshot typically has four outs to complete the straight. This is because there are four cards of the specific rank needed in a standard 52-card deck.
- Specific Card Needed: Unlike an open-ended straight draw where two different ranks can complete the straight, a gutshot requires one specific rank.
- Lower Odds: Due to having fewer outs, the probability of hitting a gutshot is lower than that of an open-ended straight draw.
Gutshot Examples in Texas Hold'em
Let's look at a few scenarios in Texas Hold'em to illustrate a gutshot:
-
Hand: A♠ Q♠
-
Flop: K♣ J♦ 7♥
- Gutshot: You need a T (Ten) to complete your A-K-Q-J-T straight. Any of the four Tens in the deck will work.
-
Hand: 8♥ 7♥
-
Flop: A♣ 5♠ 4♦
- Gutshot: You need a 6 (Six) to complete your 4-5-6-7-8 straight.
-
Hand: 9♦ 6♠
-
Flop: J♣ T♥ 7♣
- Gutshot: You need an 8 (Eight) to complete your 7-8-9-T-J straight.
Gutshot vs. Open-Ended Straight Draw (OESD)
It's crucial to distinguish a gutshot from an open-ended straight draw, as their probabilities of completion differ significantly.
| Feature | Gutshot (Inside Straight Draw) | Open-Ended Straight Draw (OESD) |
|---|---|---|
| Required Cards | One specific rank needed to fill a gap in the middle. | Two different ranks needed to complete the straight on either end. |
| Number of Outs | 4 outs (e.g., any of the four 6s for a 4-5-?-7-8 straight). | 8 outs (e.g., any of the four 9s or four K's for a T-J-Q-? or ?-T-J-Q). |
| Probability (Flop to River) | Approximately 16.5% (4 outs out of 47 unknown cards for turn/river) | Approximately 31.5% (8 outs out of 47 unknown cards for turn/river) |
Strategic Considerations When Chasing a Gutshot
While gutshots offer lower odds than OESDs, they can still be profitable to chase under the right circumstances.
- Pot Odds: Always compare the pot odds you are getting to the odds of hitting your gutshot. If the pot offers enough value to justify the risk, chasing might be warranted.
- Implied Odds: Consider the "implied odds," which are the potential chips you expect to win if you hit your straight. If you believe your opponent will pay you off heavily when you complete your straight, you might be able to chase a gutshot profitably even with poor immediate pot odds.
- Position: Playing in position allows you to see your opponent's action before making your decision, giving you more information.
- Opponent Tendencies: Against aggressive opponents who bet frequently, a gutshot might be harder to chase. Against passive opponents, it might be easier to control the pot size and get to a cheaper showdown.
- Fold Equity: If your bet or raise might make your opponent fold, you don't necessarily need to hit your gutshot to win the pot. This is often an advanced consideration.
- Nut Straight Potential: A gutshot to the "nut straight" (the highest possible straight) is generally more valuable as it's less likely to be beaten.
Chasing a gutshot should be a calculated decision, taking into account all these factors. Blindly chasing any gutshot can lead to significant losses in the long run.
