What Is a Flush in Poker? Hand Ranking Explained
A flush is a strong poker hand ranking, consisting of five cards all of the same suit, such as K♠ J♠ 8♠ 5♠ 2♠. The cards do not need to be in sequential order, which differentiates a flush from a straight flush. It beats a straight but loses to a full house, making it a powerful holding in most poker variants.
Understanding how a flush is made and how it compares to other hands is essential for any player. This guide breaks down the odds of being dealt a flush, how to play it effectively, and what happens when two players both have a flush at showdown.
How a Flush Ranks and Is Compared
In the standard poker hand rankings, a flush sits above a straight and below a full house. When comparing two flushes, the winner is determined by the highest card in the hand. If the highest cards are tied, you compare the second-highest, then the third, and so on until a winner is found.
For example, a flush with an Ace-high (A♥ 10♥ 7♥ 5♥ 3♥) beats a King-high flush (K♣ Q♣ J♣ 9♣ 2♣). If all five ranks are identical, which is rare in community card games, the pot is split. The suit itself (hearts, spades, etc.) has no value in determining a winner.
Odds of Making a Flush
The probability of being dealt a flush from a random five-card hand in Texas Hold'em is relatively low, which contributes to its strength. The odds of flopping a flush when you start with two suited cards are approximately 0.8%, or about 118 to 1 against. The odds improve as you see more community cards, but it remains a relatively rare hand.
Knowing these odds helps you assess the likelihood of an opponent having a flush when several cards of one suit are on the board. It is a key part of reading the board texture and making informed betting decisions.
- Flopping a flush with two suited cards: ~0.8%
- Making a flush by the river from a flush draw: ~35%
- Being dealt any flush in five cards: ~0.20%
Playing Flush Draws Strategically
A flush draw occurs when you have four cards of the same suit and need one more to complete the hand. This is a common and powerful drawing situation. The decision to bet, call, or raise with a flush draw depends on factors like pot odds, your position, and your opponents' actions.
Aggressive play with a strong flush draw can be profitable, as you can win the pot immediately if your opponents fold, or hit your flush later. However, it is important to avoid overvaluing a weak flush if the board shows potential for a higher flush or a full house.
- A flush draw has 9 'outs' (the remaining cards of that suit)
- Consider implied odds (future bets you might win)
- Be cautious if the board is paired (full house risk)
- Semi-bluffing with a flush draw can be effective
Frequently Asked Questions
Does a straight beat a flush?

What is the difference between a flush and a straight flush?
A straight flush requires five consecutive cards of the same suit (e.g., 5♦ 6♦ 7♦ 8♦ 9♦). A flush only requires five cards of the same suit in any order. A straight flush is a much rarer and stronger hand.
What happens if two players have a flush?
The player with the highest card in their flush wins. If the highest cards are the same, you compare the second-highest, then the third, and so on. If all five cards are of the same rank (only possible with community cards), the pot is split.
