There are various different versions of the official poker rules. The rules that govern a game of poker are usually based on the governing bodies of cardrooms, and are derived from these. The purpose of an official rulebook is to set the standards for poker. It is not intended to be a substitute for the rules of the game.

Although the official poker rules may not directly dictate how you play, they are intended to create a positive atmosphere around the poker table. Understanding the unwritten rules of poker play can increase your chances of winning. For example, slow rolling and angle shooting are considered unethical and should not be practiced. If you break these rules, it could cause your opponents to walk away or leave the table.

The professional Tournament Directors Association is responsible for maintaining the rules for the game. Founded in 2001 by poker players Linda Johnson, Jan Fisher, and David Lamb, the TDA has over 2,500 members in 63 countries. Its members include managers of major live poker rooms, circuits, and independent tournaments. Its president, Jack Effel, is the director of the WSOP.

Dead cards and hands are not legally playable. An opener is a card that qualifies a player to open the pot. A pair of kings is a common opener. The player with the blind has the option to raise or call the bet. Another type of blind is the oversize blind, which is bigger than the regular big blind. These blinds usually increase the stakes proportionally.
