Poker is a card game in which players make decisions based on the cards they have in hand. For example, a player may decide to call a raise, while another player may choose to fold. The size of the pot also plays a role in determining which players call and raise. If more than one player is involved in a hand, a player can raise several times without risking losing all of his or her money.

Depending on the rules of the game, the players may be required to contribute a sum of chips before the game begins. This is known as the blind or the ante. The dealer then shuffles and cuts the cards. Players then bet according to the rank of their hand. In some forms, players may also raise their bets or check their cards. When a player calls or raises, he or she must match the previous bet. Alternatively, a player may check, which means they did not make a bet at all.

After you have a basic understanding of the game, you should try out various poker variations to improve your skills. A good tip is to shuffle the cards several times before playing. This will help you develop your instincts and determine which cards you should hold.
