What is a ‘Three Flush’?
A ‘three flush’ is any set of cards which have the same suit in common – that is, three cards of either hearts, spades, diamonds or clubs. The three flush is the start of a potentially winning hand, as a five card flush is eligible for the showdown, though on its own it has no value except in rare variants of the game such as Three Card Poker.
‘Three Flush’ Explained
If a poker player refers to a ‘three flush’, they mean that they held three cards of the same value or that the board contained three cards with a matching suit. In a standard pack of playing cards, there are four groups or suits – these are the hearts, clubs, spades and diamonds. One of the winning hands which can be played for the pot is a five card flush – five cards of different values which all share the same suit. A ‘three card flush’ is not yet completed, but it is the start of a winning five card flush.
The best hand in the game is a form of flush – the royal flush. This is a straight, made of the highest valued cards, which is also made in a matching suit. The odds of finding this hand are extremely long, and it is almost always unbeatable in any form of poker. If a player holds the A-K-Q of one suit, this three card flush is the start of the royal flush and the player will hope to complete it in the flop or the draw.
There are some versions of poker where three cards can count for the win – many forms of Pai Gow Poker include a three card flush in the widened range of winning hands, and Three Card Poker specifically seeks the best three cards for the win.
