The game of Poker involves the use of chance. Every player must place some of his or her chips in the pot at certain intervals. One player has the privilege and obligation to make the first bet. In most poker variants, the first player must place enough chips to equal the total contribution made by the player before him. Hence, he or she is considered to be an active player. Therefore, players can make choices based on probability, psychology, and game theory.

During a betting round, players place an ante. This amount varies from one variant to another. Once a player has made the ante, he or she may then place a bet into the center pot. When this bet is successful, the player with the highest hand wins the pot. The betting rounds continue in a clockwise direction until all players fold or call. In cash games, players must call or raise a bet if he or she wants to continue the game.

In live poker, the right to deal a hand rotates among players. The dealer is referred to as the “buck” in the game. Typically, a white plastic disk is used as the buck. This button indicates who is the nominal dealer. Once a player has placed a bet, he or she can see his or her cards. Players may discard up to three cards from their hand, but can also take new ones from the top of the deck.
