Definition & Meaning of "straight flush"

What is a "straight flush"?

A straight flush is a poker hand that consists of five consecutive cards of the same suit. For example, five cards in a row like 4 of clubs, 5 of clubs, 6 of clubs, 7 of clubs, and 8 of clubs make a straight flush. It is a very strong hand, ranked above a flush and below a royal flush in poker hand rankings. If two players have a straight flush, the one with the highest top card wins. A straight flush is rare, and if it includes the ten, jack, queen, king, and ace of the same suit, it becomes a royal flush, the highest hand in poker.
