Straight Flush Explained

A straight flush is a poker hand that consists of five cards of sequential rank, all of the same suit. A straight flush is the second-best possible hand in most variants of poker. 

The highest-ranking straight flush, ace-high, is known as a royal flush and is particularly rare: only four such hands exist in a standard deck of 52 cards. The probability of being dealt a royal flush is approximately 1 in 650,000 hands dealt. This is the best possible hand to hold in poker, and thus a royal flush is an unbeatable hand.

The second-best possible hand is still any other straight flush, which consists of five cards of sequential rank, all of the same suit. The probability of being dealt a straight flush is approximately 1 in 72,000 hands dealt. 

Straight flushes are ranked according to the highest card in them.

If more than one player has a straight flush, the player with the highest-ranking card in their hand is the winner. As an example: if two players both have an ace-high straight flush (the strongest possible hand), the one with the higher second-highest card is the winner. For example, if Player 1 has, A♣ K♣ Q♣ J♣ 10♣ and Player 2 has K♦ Q♦ J♦ 10 ♦ 9♦, then Player 1 would win because their Ace is higher than Player 2’s King.

How to Play a Straight Flush Hand

Now you know that a straight flush is higher than four of a kind, a flush, and a straight, but lower than a royal flush. The Ace may be high or low in a straight flush, but it cannot “wrap around.” Aces are always high in poker.

If you are dealt a straight flush, you can consider betting higher, as the hand is rare, and the possibility that another player holds a higher-ranking straight flush is considerably low. After all, with odds of 1 in 72,000 (or 0.00139%), it is a very uncommon hand. 

If someone else bets before you do, you can still bet aggressively to try to win the pot. Unfortunately, a very common mistake many players make is playing too passively (known as slow-rolling) with a straight flush or other high-ranking hands. This can cause them to miss potential wins or even lose the hand altogether.

Remember: the key to being a clever player in poker is to bet when you have good cards and to fold when you don’t.
