Poker is a card game with hundreds (maybe thousands) of variations, but most follow the same basic rules. The objective is to form the best five-card hand by betting during each round. The winning player collects the pot of money. In some games, players who have not folded may reveal their hands in a showdown to decide the winner.

Poker offers many mechanisms by which players can strategically misinform each other about the value of their cards, including small bets to keep the pot growing or large bets to intimidate weaker players into folding before showdown. It also allows players to bluff, although the success of any given bluff depends on both the player and his or her perceptions about the strength of an opponent’s hand.

Losing at poker is hard, and not just because of the lost money. Poker is steeped in machismo, and to admit that your opponent is stronger, smarter, or just plain better than you is an enormous blow to ego. This machismo can lead to passive poker players who avoid conflict, dressing moderately, stacking chips neatly, and talking seldom.

A strong poker game requires aggressiveness, but this doesn’t mean “calling every bet,” as some novices mistakenly think. In reality, a well-timed aggression is key to increasing your win rate against weaker opponents and competing with stronger ones. Moreover, self-honesty is a critical part of poker; it does little good to learn the proper strategy if you are not prepared to use it in a given situation.
