Poker is a card game that can be played by two or more players. It can be a competitive, strategic game of chance, but it is also an artful mixture of psychology, mathematical analysis and games theory. Its lore is full of stories about legendary bluffs and misdirection, but in the end it is a game of cards.

The game is typically played from a standard deck of 52 cards, although some variants may add a few jokers as wild cards. There are four suits (spades, hearts, diamonds and clubs) and no suit is considered higher than another. The highest hand wins the pot, which consists of all bets placed by players during one betting round. Depending on the rules of the game, players may discard and draw replacement cards before placing their bets again.

A good poker player should always look for opportunities to bluff when holding a weak hand, as this will often force players into making strong calls. In addition, it is important to read other players’ behavior. A large part of this skill involves subtle physical “tells” that can be picked up by other players, but it can also be learned from patterns in a player’s betting behavior.

The person to the left of the dealer is known as the button, and he or she will place the first bet during any betting interval. After the first bet is placed, players have a choice to either raise or check. If raising, the player must match or raise the amount of the previous bet and must do so in turn.
