the act of bluffing in poker; deception by a false show of confidence in the strength of your cards

A hand with four cards of a suit. Not enough for a flush.

A hand in which four of the cards are the same suit. A four flush is not ranked as a winning hand, but may become a strong hand if there are more cards to draw.

A Hand with four Cards of the same Suit.

When four cards to a flush appear on the board, giving every player with just 1 card of the particular suit to make the flush. Particularly annoying when you flop a flush but are holding generally "weak" kickers. The board then "four flushes" on the turn and gives others holding a higher card of that suit a chance to beat you.

n. Four cards to a flush.

Four cards of the same suit, such as four hearts, together with an odd card.
