Poker is a card game played by two or more players. The aim of the game is to win money by having the best hand out of a standard 52-card deck. The game can be a complex one, and there is an element of skill involved in understanding probability and game theory.

The rules of poker vary depending on the variant being played. Generally, the game starts with each player placing money into an initial pot (called an ante).

Next, each player receives cards face-down and places bets accordingly. Then, the players take turns revealing their cards. The player with the best hand wins the round and the bets made in that round.

In some variants of poker, players must also place an amount called a blind bet before the cards are dealt. These bets can replace the ante, or they can be made in addition to the ante.

A player can choose to fold, check or call when they have no more money to bet. To check, the player may do any of the following:

Tapping the table with fists or knuckles is a common way to indicate checking.

To call, a player must have sufficient chips to match the amount being called by another player; otherwise, the player must fold and lose the bet. To raise, a player must have an additional amount of chips to match the amount being raised by another player; otherwise, the player must also fold and lose the bet.
