If you are staring at the board and wondering, does a flush beat a straight, you are not alone. The short answer is yes! A flush always beats a straight in standard poker games like Texas Hold’em or Pot-Limit Omaha (PLO).
But why is that the case, and does this rule ever change depending on where you play? Let’s break down the official hand rankings, the mathematical probabilities, and some surprising twists from other poker variations.
Flush vs. Straight in Standard Poker Hand Rankings
| Hand Type | Example | Probability | Rank |
|---|---|---|---|
| Flush | A♠ 10♠ 7♠ 4♠ 2♠ | 3.03% | 5th strongest |
| Straight | 9♥ 8♠ 7♦ 6♠ 5♣ | 4.62% | 6th strongest |
According to official poker hand rankings, flush outranks straight every single time, unless you are playing a special type of poker that we will discuss later.
Here is the list of hands from the strongest to the weakest holdings:
- Royal Flush
- Straight Flush
- Four of a Kind
- Full House
- Flush
- Straight
- Three of a Kind
- Two Pairs
- One Pair
- High Card
As you can see, Flush ranks in the #5 spot in overall rankings and is above the Straight, which is ranked #6.
Why Does a Flush Beat a Straight?
The reason why a flush is a better hand than a straight breaks down to simple math. In poker, the strength of a hand is determined by its scarcity: the harder a hand is to make, the higher it ranks.
If you consider all 7 cards in a standard game of Texas Hold'em, you will simply hit a flush less often than a straight. Here are the exact probabilities:
- Odds of flopping a flush: ~0.20%
- Odds of flopping a straight: ~0.39%
- Odds of making a flush by the river: 3.03%
- Odds of making a straight by the river: 4.62%
Because there are fewer combinations of flushes available in a 52-card deck, the math dictates that the flush takes the pot.
Tiebreakers: When Both Players Hit the Board
In highly coordinated runouts, both players might end up having a flush or a straight. Here is how you determine the absolute winner in those tricky spots:
- Straight vs Straight: The player with the highest top card wins. (E.g., Q-J-10-9-8 beats 10-9-8-7-6.)
- Flush vs Flush: The highest card in the flush wins. If the top cards are tied, you compare the next highest, and so on until the tie is broken. (E.g., A♠-J♠-9♠-7♠-5♠ beats K♠-Q♠-10♠-7♠-6♠.) Note on suits: Suits do not have rankings in standard poker. Spades do not beat Hearts. If two players have the same card values in different suits, the pot is split.
The Exception: When a Straight Beats a Flush
While a flush is stronger in standard games, the logic can actually be flipped in a couple of specific variations that alter the deck size. Rankings are not a law of nature; they are a design choice based on deck structure.
- Short-Deck Poker (36 cards): By removing the 2s through 5s, the probabilities shift dramatically. In some specific short-deck or stripped-deck formats, straights become mathematically rarer than flushes. To reflect this, the rules are adjusted so that straights actually outrank flushes.
- Stripped-Deck Games (like a 32-card Piquet deck): With fewer suits or ranks in play, hand distributions change entirely, sometimes making flushes too common compared to other hands. House rules often push straights above flushes in these regional games.
Key Takeaways
- Standard Rule: If anyone asks, does a flush beat a straight, the answer is always yes in Texas Hold’em, Omaha, and most standard 52-card games.
- The Math: A flush (3.03%) is mathematically harder to hit than a straight (4.62%).
- Exceptions: In certain short-deck or stripped-deck variations, the math changes, and a straight can rank above a flush.
