Flop, Turn, and River
The three named stages at which community cards are revealed in Hold'em and Omaha, each followed by a betting round.
Definition
In flop-based poker games, the community cards are revealed across three named 'streets.' The flop is the first three community cards dealt at once; the turn (or fourth street) is the single fourth card; and the river (or fifth street) is the single fifth card. A round of betting follows each, and betting also occurs preflop before the flop, giving Hold'em four betting rounds total. Each new card can dramatically shift who is ahead, so decisions compound: a hand that is strong on the flop may be weak by the river. The word 'street' is often used generically for any of these betting rounds.
Worked example
A player flops top pair, sees a scary flush card arrive on the turn, and checks cautiously; the river pairs the board, and they reassess whether their pair is still likely best.
Why it matters
Learners need the vocabulary and the sequence to follow a hand and know when betting happens. Professionals plan hands street by street, thinking ahead about how future cards change ranges and what they will do on later streets before acting on the current one.
