What Beats a Flush in Poker

Quick Answer: What Beats a Flush?

A flush is a strong hand, often enough to win a pot on its own, but it is not invincible. In standard poker hand rankings, a flush sits in the middle of the pack. It is the fifth-best hand out of ten — only royal flush, straight flush, four of a kind and full house beat it. This means there are exactly four hand classes that will beat your flush if they appear on the board or in your opponents' hands.

The four hands that beat a flush are:

• Full House (three of a kind plus a pair)
• Four of a Kind (four cards of the same rank)
• Straight Flush (five cards of the same suit in sequence)
• Royal Flush (the highest possible straight flush: A-K-Q-J-10 of the same suit)

If you hold a flush, you need to be wary of these four combinations. However, if your opponent holds anything lower — such as a straight, three of a kind, two pair, a pair, or high card — your flush wins. Understanding this hierarchy is essential for making correct betting decisions, especially when you are considering whether to call a large bet or go all-in on the river.

The Four Hands That Beat a Flush

To play your flush confidently, you must understand the specific hands that dominate it. Let’s look at each of the four superior hands in detail.

Full House

A full house consists of three cards of one rank and two cards of another rank (e.g., 8♥ 8♣ 8♠ 2♦ 2♣). It is the most common hand to beat a flush in Texas Hold’em because the board often pairs or trips. For example, if you have K♥ 9♥ and the board comes 7♥ 5♥ 2♥ 2♠ 2♦, you have a king-high flush. However, your opponent with 2♣ 8♣ has a full house (twos full of eights). The full house wins because it combines both a three-of-a-kind and a pair, making it statistically more robust than five cards of the same suit that are not in sequence.

Four of a Kind

Four of a kind, also known as "quads," consists of four cards of the same rank (e.g., 10♠ 10♥ 10♣ 10♦) plus a kicker. This hand is less common than a full house but beats it. If the board shows 10♠ 10♥ 10♣ 5♦ 2♥ and you hold K♥ 9♥ for a king-high flush, an opponent holding 10♦ 8♣ has four tens. The four of a kind wins because having four cards of the same rank is rarer and therefore stronger than five cards of the same suit.

Straight Flush

A straight flush is five cards of the same suit in consecutive order (e.g., 5♠ 6♠ 7♠ 8♠ 9♠). This hand beats a regular flush because it satisfies two criteria simultaneously: suit and sequence. If you hold J♥ 10♥ and the board is 9♥ 8♥ 7♥ 3♦ 2♠, you have a jack-high flush. But if your opponent has 6♥ 5♥, they have a nine-high straight flush. The straight flush wins because the sequence adds an extra layer of difficulty to achieve, making it rarer than a standard flush.

Royal Flush

The royal flush is the highest possible straight flush: A-K-Q-J-10 of the same suit. It is the ultimate poker hand. It beats every other hand, including other royal flushes (which result in a split pot if two players have them in a single hand, though this is extremely rare). If you hold A♥ K♥ and the board is Q♥ J♥ 10♥ 5♦ 2♣, you have a royal flush. No other hand can beat it. It is the pinnacle of the poker hand hierarchy.

Tie-Breaking Between Two Flushes

When two players both have a flush, the hand with the highest card wins. This is known as the "ace-high flush" being the strongest, followed by king-high, queen-high, and so on. If the highest cards are the same, you compare the second-highest cards, then the third, and so on, until a winner is found.

For example, if Player A has A♥ 8♥ and the board is K♥ J♥ 5♥ 3♦ 2♠, Player A has an ace-high flush (A-K-J-8-5). If Player B has Q♥ 9♥, they have a queen-high flush (Q-J-9-5-3). Player A wins because the ace is higher than the queen. The suit does not matter; hearts, diamonds, clubs, and spades are equal in value unless specified by a variant like "War" or "High-Low."

If both players have the same highest card, you move to the next card. Suppose Player A has K♥ 10♥ and Player B has K♥ 9♥, and the board is Q♥ J♥ 5♥ 3♦ 2♠. Both players have a king-high flush. Player A’s flush is K-Q-J-10-5, while Player B’s is K-Q-J-9-5. Player A wins because the 10 is higher than the 9. If all five cards are the same (which can happen if both players use the same five board cards), the pot is split.

Note that only the best five cards count. If you have A♥ K♥ and the board is Q♥ J♥ 10♥ 9♥ 8♥, you have a royal flush. If your opponent has 7♥ 6♥, they have a nine-high straight flush. You win because your straight flush is higher. The suit is irrelevant; only the ranks matter.

Common Confusions (Straight, Three of a Kind, Two Pair)

Many beginners and intermediate players get confused about where a flush sits relative to other hands. Let’s clarify the most common misconceptions.

Does a Straight Beat a Flush?

No. A flush beats a straight. A straight is five cards in sequence, but they do not need to be the same suit (e.g., 5♠ 6♥ 7♦ 8♣ 9♠). A flush is five cards of the same suit, but they do not need to be in sequence (e.g., A♥ 8♥ 5♥ 3♥ 2♥). Because a flush is rarer than a straight, it ranks higher. This is a common mistake, so remember: Flush > Straight.

Does Three of a Kind Beat a Flush?

No. A flush beats three of a kind. In the standard hand-ranking ladder — Royal Flush, Straight Flush, Four of a Kind, Full House, Flush, Straight, Three of a Kind, Two Pair, One Pair, High Card — a flush sits two rungs above three of a kind. Example: a flush of 9♣ 7♣ 5♣ 4♣ 2♣ beats trip Aces (A♥ A♦ A♠ K♣ 6♣).

Does Two Pair Beat a Flush?

No. Two pair (e.g., K♥ K♣ 8♦ 8♠ 5♣) is the eighth-highest hand. A flush is fifth-highest. So, Flush > Two Pair. This is a common spot where players overvalue their two pair and lose to a flush. For example, if you have K♥ K♣ and the board is 8♦ 8♠ 5♣ 2♥ 3♥, you have two pair (kings and eights). If your opponent has 10♥ 9♥, they have a flush. Your two pair loses to their flush.

How Often Does a Flush Beat or Lose?

Understanding the frequency of flushes helps you gauge their strength. In Texas Hold’em, the probability of flopping a flush draw (four cards of the same suit) with a suited hand is about 10.9%. The probability of completing that flush by the river is about 35% (9 outs × 4 = 36%, or exactly 35.0%).

When you make a flush, it is often a strong hand but never a guarantee. Against a single opponent with a random hand, a made flush is usually a comfortable favourite, but the margin shrinks fast when the board is paired (full-house possible) or four-flushed (a higher flush possible). However, against multiple opponents, the chances of someone holding a higher flush or a full house increase. For example, if three players see the river, the odds that at least one of them has a full house or a higher flush are significant.

It is also important to consider the board texture. If the board is "dry" (e.g., A♠ K♦ 8♣ 5♠ 2♥), a flush is less likely to be beaten by a full house because there are fewer pairs on the board. If the board is "wet" (e.g., 8♥ 8♦ 5♥ 3♥ 2♥), a flush is more likely to be beaten by a full house or a higher flush. Always assess the board when evaluating your flush’s strength.

Examples at the Table

Let’s look at some realistic scenarios to illustrate how these hands play out.

Example 1: Flush vs. Full House

You hold J♥ 10♥. The flop comes 9♥ 8♥ 2♦. You have a flush draw. The turn is 5♥. You make a jack-high flush. The river is 2♣. Your opponent calls your bet and turns over 2♠ 2♥. They have a full house (twos full of jacks). Your flush loses. This is a classic "set over flush" scenario where the board pairs, giving your opponent a full house.

Example 2: Flush vs. Straight

You hold A♥ K♥. The board is Q♥ J♥ 10♦ 5♠ 2♣. You have an ace-high flush. Your opponent has 9♠ 8♠. They have a queen-high straight (Q-J-10-9-8). Your flush wins because a flush beats a straight. This is a common spot where players with a straight might overvalue their hand and call a large bet, only to lose to a flush.

Example 3: Flush vs. Higher Flush

You hold K♥ 9♥. The board is A♥ Q♥ J♥ 5♦ 2♠. You have a king-high flush. Your opponent has A♥ 8♥. They have an ace-high flush. Your opponent wins because the ace is higher than the king. This is a common mistake where players with a king-high flush assume they have the best hand, only to lose to an ace-high flush.
