A flush is a poker hand such as Q♣ 10♣ 7♣ 6♣ 4♣, where all five cards are of the same suit, but not in sequence. Two flushes are compared as if they were high card hands; the highest-ranking card of each is compared to determine the winner. If both hands have the same highest card, then the second highest-ranking card is compared, and so on until a difference is found. If the two flushes contain the same five ranks of cards, they are tied and split the pot, that is, suits are not used to rank them.
Flushes are described by their highest card, as in "queen-high flush" to describe Q♦ 9♦ 7♦ 4♦ 3♦. If the rank of the second card is important, it can also be included: K♠ 10♠ 5♠ 3♠ 2♠ is a "king-ten-high flush" or just a "king-ten flush", while K♥ Q♥ 9♥ 5♥ 4♥ is a "king-queen-high flush". In community card games the highest card in the flush may be a community card which is used by multiple players, in which case the flush may be described by the highest non-communal card; in a game with community cards A♣ 10♣ 6♣ 2♣, a player holding Q♣ J♦ would have a "queen-high flush" while a player with K♣ 10♠ holds a "king-high flush"; both players making use of the high ace.
In five-card poker, there are 5,148 possible flushes, of which 40 are also straight flushes; the probability of being dealt a flush that is not also a straight flush is approx 0.196\% .
In seven-card poker, the frequency of flush is 4,047,644, the probability of being dealt one is approximately 3.03%.
