Poker is a card game where players place bets without seeing their opponents’ cards. Each player may choose to check (not put any money into the pot), call a bet made by another player, or raise it. A raise is a bet higher than the last one made by any active player. This method encourages competition and makes the game more fun.

Each player has a set of five cards to create a hand. The highest hand is the royal flush, which contains a ten, jack, queen, king and ace of the same suit, in order. Other high hands include the straight flush and three of a kind. Two pair is two distinct pairs of cards and a fifth card, while high card breaks ties when nobody has any of the other hands.

Poker is a game of deception, in which players try to give away bits of information about their hands and force their opponents to change their strategy. A good poker player uses deception in both bluffing and semi-bluffing, where they bet on a weak hand in the hope of making their opponent(s) fold superior hands. Each action a player takes, including whether to check, bet or raise, tells a story about their hand and gives clues about their strength or weakness to their opponents. Learning poker is both a science and an art: the science is being disciplined to follow best practices, while the art is knowing when to break those rules and adjust your style on the fly.
