Poker is a card game played by two or more players. Each player places an ante or blind bet before the cards are dealt. The goal is to win the pot, which is the sum of all bets made during a hand. There are many different forms of poker, but the game generally involves betting and a showdown in which each player reveals their cards and the highest hand wins.

Each player starts with two personal cards and the five community cards on the table. Some games allow the player to replace their cards, usually during or just after the first betting round. Depending on the rules of the game, these replacement cards may be added to the community cards or used to form a separate poker hand.

The standard pack of 52 cards contains four suits: spades, hearts, diamonds and clubs. The cards rank from high to low (ace, king, queen, jack). Some variants use additional cards, such as wild cards or one-eyed jacks.

A poker hand is formed from five cards and the highest hand wins. If a player has a pair, they are considered to have a strong hand and can make bets that will scare off others waiting for their own pairs or higher. If the hands are tied, the high card breaks the tie. This is a general rule, but specific rules for the ranking of ties are often defined by game. It is important to learn how to identify conservative and aggressive players, as they are a major part of the betting pattern of a hand.
