In poker, a betting round is a phase during a hand where players can place bets, check, call, raise, or fold. Each round allows players to assess their hands and make strategic decisions based on their cards and the actions of others. The number of betting rounds varies depending on the specific game being played, such as Texas Hold'em or Omaha. Typically, a betting round occurs after the initial deal and after community cards are revealed. Players take turns in a clockwise direction, and the round continues until all players have either called the highest bet or folded. This process is crucial for determining the pot size and the overall outcome of the game.
