What is a ‘Straight Flush’?
A straight flush is the second best hand which can be drawn in most types of poker, including Texas Hold ‘Em. This exceptionally strong hand sees the player holding five consecutive cards which all belong to the same suit. Any combination of consecutive cards can be used to make this hand, with the only exception being if a player holds a 10, Jack, Queen, King and Ace of the same suit. This is known as a royal flush and is the best hand possible in poker.
‘Straight Flush’ Explained
A straight flush is an excellent hand for a poker player to receive; however, they don’t come along very often. The mathematical probability of receiving this hand is 37,260-1. The odds of a player drawing a royal flush – a type of straight flush and the only hand which can beat a straight flush – are calculated as 649,739-1.
Since at least three community cards must share the same suit in order to enable a straight flush, it is only possible for a maximum of two players to have this hand once all players have been drawn. In this instance, the winner is determined by the player whose straight flush ends with the highest card.
A straight flush is always referred to in relation to the highest card of the straight. For example, if a player were to hold a hand containing a 4, 5, 6, 7 and 8 of hearts, this would be called an 8 high straight flush.
In a standard deck of 52 cards, there are 40 possible straight flushes available, including royal flushes. Aces can be used as both a low and high card to create a suited hand of A, 2, 3, 4, 5 or a royal flush as per the above example.
