Poker is a card game that involves betting between players. It is usually played with a minimum of seven cards. Each player has two personal cards and five community cards. A hand is made by combining the best possible combination of the two personal cards and the five community cards. A pair is 2 matching cards of the same rank. A full house is 3 cards of the same rank and 2 matching cards of another rank. A straight is 5 cards of consecutive rank but from different suits. A flush is 5 cards of the same suit. The highest hand wins.

The game is typically played with poker chips, with each player purchasing a fixed number of chips at the beginning of the game. Each player may “call” a bet by putting the same number of chips into the pot as the player to their left. A player may also raise a bet, in which case the players to their left must either call or fold.

Bluffing is a key element of the game, and a well-executed bluff can dramatically alter the odds of winning a pot. However, if too much is bluffed, a player will lose money in the long run. For more, read Doug Polk’s article on bluffing.

The poker community has developed a wide range of strategy tools to analyze and improve their games, and it is common for players to form study groups. Some of these groups are formal, and some informal, but all share the same goal: to become a better poker player. Meta-skills are the building blocks of a good poker player. They include: Opportunities, Strategy, and Execution.
