The Rules of Poker

Poker is a card game in which players make bets with chips that are collected into a pot before the cards are revealed at “showdown.” Each player has two private cards. The object of the game is to make a better five-card hand than any other player before showdown. While the game is based on chance, skill can reduce the variance of luck over time.

The rules of poker include an implicit assumption that all players are honest. This assumption can be weakened, however, by the prevalence of GTO strategies that encourage professional players to organize their approach into a series of rigid and formal moves. The resulting poker culture is hierarchical and fearful, with the top players maintaining a dominant position that discourages other professional players from challenging them.

When a player makes a bet, the players to his left must either call (put into the pot at least the same number of chips as the bet) or raise the amount of the bet. A player may also check, meaning he does not want to participate in the current betting interval, or drop, indicating that he is folding his hand.

Expert poker players know how to hide tells, the unconscious, physical clues that reveal the strength of their hands. These can include facial or body tics, nervous habits such as biting finger nails, or staring at the cards for too long. The players use these cues to strategically misinform their opponents about the value of their hands.
