Poker is a card game of skill and strategy that can be played by two or more players. It is usually played with a conventional 52-card deck, although there are many variants that use alternative deck sizes. The objective of the game is to win wagers by having the highest ranked hand when the cards are revealed. There are several ways to achieve this goal, including bluffing, calling bets and raising ones own.

The game is often fast-paced, with players betting chips continuously until one player has all of them or everyone folds. A key element of good poker is reading the opponents. Observe experienced players to learn how they react and try to mimic their behavior, as this will help you develop quick instincts.

During a betting interval, a player may choose to bet any amount in proportion to the contributions made by players before him. A player who makes a bet that exactly matches the previous player’s bet is said to call, and a player who increases the size of his bet is said to raise.

The player with the best ranked hand wins the pot, which is all of the money that has been bet during a particular deal. However, players may also place bets in side pots based on different criteria. In these side pots, the winner is not always the player with the best hand but the player who contributed the most to the side pot.
