Full explanation — Flush
A flush is a five-card poker hand where all five cards are of the same suit, such as five hearts or five spades. Unlike a straight, the cards do not need to be in sequential order. A flush ranks higher than a straight but lower than a full house in the standard poker hand hierarchy. When multiple players hold a flush, the player with the highest-ranked card in their flush wins. Recognizing potential flush draws and understanding their equity against other hands is a fundamental aspect of successful poker strategy, particularly on suited boards.
