Poker is a card game played by two or more players. The cards form a hand, and the highest-ranking hands win. Players may also bet that they have the best hand, which other players must call (match) or fold. Some players win by bluffing, betting that they have a superior hand when in fact they do not.

The rules of poker vary from game to game, but most games involve a standard pack of 52 cards and four suits (spades, hearts, diamonds and clubs). A poker hand comprises five cards: two personal cards held by the player, and three community cards revealed during or after the betting round. Some poker games include jokers as wild cards, and some poker variants use more than one pack or add extra cards.

A good poker player must be able to read the other players at the table. This is a vital skill in poker and has been the subject of many books and articles. However, it is important not to over-focus on unconscious tells, which can be very misleading. Instead, learn to identify a player’s general mood, track their eye movements and note how they handle their chips and cards.

Position is vital in poker, as it gives you bluff equity and allows you to make more accurate value bets. However, in addition to good position you must be able to decide what stakes and game variations are most profitable for your bankroll.
