Poker is a game of decision making, and one of the most important ones is deciding whether to play a hand or not. In making this decision, players must decide whether their action will result in a positive expectation, and whether or not it will help them win money in the long term. There are many variables involved in poker, but two underlying dimensions are largely unaffected by luck: the number of hands dealt and the skill of the players.

Players make voluntary money bets, except for the initial forced bet. These bets must have a positive expected value, and may be placed for many different strategic reasons. Although there is some element of chance in the outcome of each poker hand, game theory, probability, and psychology play a major role in determining long-term player expectations.

Ethics are another important factor in Poker. Though there are no explicit laws governing the game, players are expected to behave in an ethical manner. Local gaming establishments may adopt their own rules and regulations, depending on their local preferences. It is common for clubs to adopt their own house rules, which should be clearly written down. In case of disputes, it is better to refer to the written code of Poker laws.

Knowing the game rules can be extremely helpful. This will help you play the game better, even if you are playing multiple tables. It is also important to fold strong hands frequently, as doing so can help you break attachments with good pairs.
