Poker is a card game played by two or more players and involves betting and raising hands. The game may be played in a casino, private home, or online. Regardless of where it is played, the rules are similar. The player with the highest hand wins. A high hand can consist of one pair, two pairs, three of a kind, a straight, or a flush.

To begin the game, each player purchases a specific number of chips. Typically, white chips are worth one unit, red chips are five units, and blue chips are ten or more units. Once a player has purchased their chips, the dealer shuffles and cuts the deck, and the first of several betting rounds begins.

During each round, each player must either match the amount of the largest raise or fold their hand. When a player makes a bet, the players to their left must call that bet by putting in an equal number of chips into the pot. The dealer then deals the cards.

When a player’s turn comes, they must pay attention to their opponents and read their body language. For example, if a player blinks rapidly, swallows excessively, or puts their hand over their mouth they are probably trying to hide a smile and are possibly bluffing. Similarly, if a player stares down at their chips they probably have a strong hand and are not afraid to make big bets. This information is invaluable when reading opponents and making good decisions.
