Poker is a family of card games, where players use their five cards to make the best hand possible. There are many variations of poker and the rules vary depending on the game. These variants are played with different cards, number of players, and deck configuration.

The most common poker variation is Texas Hold’Em. It can be played with anywhere from two to seven players. Players put a fixed amount of money into the pot and use their five cards to make the highest hand possible.

Each player is given five cards face down. They can discard or replace the cards before they play. Some players may shuffle the cards.

After the deal, the players have to decide whether to fold, call, raise, or check. If a player does not open, they are indicating that they want to stay in the game.

Before the first bet, each player is dealt one card face up. This is known as the “opener”.

In some betting structures, the minimum opening is a double-big blind bet. A double-big blind bet is a bet that is twice the size of the ante.

In other betting structures, the opening is a small bet. When the first player folds, the turn to bet passes to the next player.

The last player to act in a round is the player on the dealer’s right. He or she is the dealer. Depending on the poker variation, the dealer can choose to take an additional card.
