Poker is a card game where players form hands using cards that are dealt to them. Each hand is made up of five cards, which must be of the same suit. The highest card gives the value of the hand.

A straight is a set of five consecutive cards from the same suit. It is even rarer than a four of a kind. A pair is two cards of the same rank, which may include an ace. Another type of straight is a flush, which is a set of five cards in which one or more cards have the same suit.

In poker, the goal is to have the best hand. To do this, players use their cards and the community cards to form their hands. When a player’s hand is revealed, the other players are forced to call or fold. If no one calls, the winner takes the pot.

Players choose actions based on their probability of winning, their strategy and how the other players play. For example, optimal strategy suggests that a player should always play hands that are higher than six or fold all other hands that are worse than four.

Three rounds of dealing are used to distribute the cards. During each round, the dealer moves one spot clockwise. After each round, the player to the left of the dealer button is the first to receive the cards. Cards are dealt to the rest of the players in order of betting.

The player to the left of the dealer button posts the small blind and the other player posts the big blind. In each round of betting, all but one player is allowed to fold. However, if someone raises, the play proceeds to the next round. This action is also known as “checking”.

The next round of betting begins with the player to the immediate left of the dealer button. This player is given the first two cards. Normally, the second blind is equal to the double first blind. Before the deal, the player to the left of the button will put down a number of chips that is equal to the total amount of the previous bettor’s contribution to the pot.

During the final round of betting, a showdown is played. The player with the best hand takes the pot. If no one has a better hand, then the pot is shared between the remaining players. Depending on the rules of the game, there may be multiple side pots.
