Flop (poker)

In poker, the flop refers to the dealing of the first three face-up cards to the board, or to those three cards themselves, in community card poker variants, particularly Texas hold 'em and Omaha hold 'em.The three cards are dealt simultaneously following the completion of the opening round of betting. After the flop, there is a second round of betting, which is followed by the dealing of a fourth, or turn, card; and a fifth, or river, card. The three cards are often dealt face-down in a stack, then the stack is turned face-up and quickly slid to one side to expose all three cards, such that a player cannot be seen to be reacting to one particular card.
