Poker is a card game played by a group of people around a table. Each player has a stack of chips that they can use to place bets during each hand. When the betting round is over, whoever has the highest-ranked hand wins all of the chips that were bet.

Before each hand, players must place a bet called an ante. Some poker games also have blind bets, which take the place of the ante or are in addition to it. Once all bets have been placed, each player receives two cards. They can then combine them to form a hand. The best five-card hand wins the pot, or all of the bets that were placed on the hand.

After the cards have been dealt, players take turns revealing their hands. Depending on the rules of the game, they can then choose to fold, call, raise, or check. A player who checks surrenders their hand and cannot play in the next round.

A pair is two matching cards of the same rank. A three of a kind is three cards of the same rank, and a straight is five consecutive cards in the same suit. A high card breaks ties when hands tie on pairs, three of a kinds, and straights.

Poker is a game of chance, but it also involves a lot of psychology and math. Many professional poker players spend a great deal of time learning how to read their opponents and analyzing the results of hands they have played. This practice is sometimes referred to as GTO, or “Gunslinger Theory.”
