An inside straight is a straight draw that needs one specific missing rank in the middle to complete the straight. In video poker, the term matters because inside straight draws are often weaker than players think, especially when compared with high pairs, stronger draws, or made hands.
Plain Talk
An inside straight is also called a gutshot. You have four cards that could become a straight, but only one rank fills the hole.
Example: 5-6-8-9 needs a 7. That is an inside straight draw. The missing card sits inside the sequence.
The problem is not that the draw can never hit. It can. The problem is that it has fewer ways to hit than an outside straight draw.
| Term | Plain-English meaning | Where it appears | Why it matters |
|---|---|---|---|
| Inside straight | Needs one middle rank | Poker/video poker | Fewer completion cards |
| Gutshot | Common slang for inside straight | Poker rooms and strategy talk | Same basic idea |
| Outside straight | Can complete at either end | Poker/video poker | More completion cards |
| Straight | Five cards in sequence | Final hand ranking | Determines payout |
Where You See It
You see inside straight language in video poker strategy charts, poker coaching, and player talk at poker tables. In video poker, it appears when a player decides whether to keep four cards to a straight, break a pair, or chase a better draw.
Why It Matters
Inside straights matter because they look close. Four cards are already lined up. The player feels like the hand is “one card away,” which is true but incomplete.
Many casino mistakes come from confusing closeness with value. An inside straight may have fewer winning replacement cards than a player assumes. In video poker, a strategy chart may prefer a high pair, high cards, four to a flush, or another hold over a low-value inside straight.
Example
You are dealt:
| Cards kept | Missing card | Draw type |
|---|---|---|
| 5♣ 6♦ 8♠ 9♥ | 7 | Inside straight |
| 10♠ J♠ Q♦ K♣ | 9 or A | Outside/open-ended straight |
| 2♥ 3♣ 4♦ 6♠ | 5 | Inside straight |
With 5-6-8-9, only a 7 completes the straight. Any 7 works by rank, but no other rank completes it. That narrower path is the key point.
From the Casino Side:
From the casino side, inside straight mistakes are part of the difference between theoretical return and actual player return. The paytable assumes a specific strategy if the published return is based on optimal play. Real players often chase weak draws because the screen makes the hand look nearly complete.
Video poker performance depends on paytable, speed, denomination, player mix, and decision quality. The casino does not need to trick a player into chasing gutshots; the human brain often does that by itself.
Common Misunderstanding
The common misunderstanding is thinking “four to a straight” is one category. It is not. Inside straights and outside straights can have different values. Some are playable in certain games. Some are trash compared with better holds.
Hard Truth
An inside straight feels one card away, but the casino is paid by probabilities, not feelings. Close-looking hands can still be bad holds.

FAQ
Why is it called an inside straight?
Because the missing rank is inside the sequence, not at either end.
Is an inside straight the same as a gutshot?
Yes. Gutshot is the common poker slang for an inside straight draw.
Is an inside straight always a bad video poker hold?
No. It depends on the game, paytable, and other cards in the hand. But it is often weaker than players assume.
How many ranks complete an inside straight?
One rank completes it. In a fresh deck, there can be up to four cards of that rank available, but discarded and dealt cards change the real situation.
Why do strategy charts treat straight draws differently?
Because not all straight draws have the same number of outs or the same competing value from other cards in the hand.
Deeper Insight
An inside straight is a classic example of visual bias in gambling. The hand looks nearly finished, so the brain overvalues it. Video poker strategy cuts through that by ranking the expected value of each hold.
In many games, the better question is not “Can this hand become a straight?” The better question is “What does this hold return on average compared with every other hold?”
Formula / Calculation
| Metric | Formula | Plain-English meaning |
|---|---|---|
| Draw EV | EV = Σ(Probability of Final Hand × Payout) | Average value of the draw |
| Straight-draw hit frequency | Hit Frequency = Winning Outcomes / Total Draw Outcomes | How often the draw completes |
| Expected loss | Expected Loss = Total Amount Wagered × House Edge | Cost over repeated play |
Formula Explanation in Plain English
The inside straight is judged by how often the missing rank appears and what the completed hand pays. If the draw misses most of the time and the payoff is modest, another hold can easily be better.
