Poker is a card game where the object is to win by forming the best possible hand with your cards. It is a game of chance, but players often try to increase their chances of winning by making strategic bets on the basis of probability and psychology. It can be a very addictive and entertaining game, but it is important to realize that poker is a game of short term luck in addition to skill.

When it is your turn to bet, you must either call or raise the bet made by the previous player. Saying “call” means that you want to bet the same amount as the last person, and this is done by placing your chips or cash in the pot. You can also fold at any time during the hand by saying “I’m folding” or similar.

Before betting begins, all the cards are placed face up in front of the players. Each player then takes turns revealing their hand. The player with the best five-card poker hand wins the pot. Players may also choose not to reveal their hands, but this usually reduces their chances of winning.

The strategy of a good poker player often involves deception and bluffing. For example, a player with a weak hand will often bet large amounts of money in order to induce opponents into folding superior hands. This strategy is called bluffing, and it can be very effective in increasing one’s chances of winning.
