Poker is a card game that involves betting between two or more players. The game has a variety of strategies and tactics that can be used to increase the chances of winning a hand. While luck plays a role in the outcome of any particular hand, the long-run expectations of players are determined by their actions chosen on the basis of probability calculations and game theory.

To begin the hand, each player is dealt two cards that are known as hole cards. After the initial deal, there is a round of betting that starts with the players to the left of the dealer. Once the betting is done, there is a sequence of three cards that are dealt face up on the table and are known as the flop, followed by an additional single card that is known as the turn and then another final card that is called the river.

After the players have analyzed their own hand and the community cards, they can decide whether to call the remaining bets and hope for luck or fold and let someone else take the chance. Saying “call” means that you want to match the previous bet and put your own chips or cash into the pot. Saying “raise” means that you want to increase the amount of money that you are putting into the pot.

There are many different ways to play Poker and the rules vary by game variant, but most involve a small number of players around a table who each have their own stack of chips. Players bet on their hands, which are known as the pot, until one player has all of the chips or everyone has folded.
