Poker is a card game in which players place bets on the strength of their hands. Each hand consists of five cards. The value of a poker hand depends in inverse proportion to its mathematical frequency; the more rare a hand, the higher its rank. A player may choose to bet that he has a good hand, or he may bluff. In either case, the players who call his bet must put in chips to match his bet or to raise it. If a player cannot call the bet, he must “drop” his cards and leave the table.

Players can also check, which means they do not want to bet. This is allowed, unless the game rules say otherwise. If the player checks during a betting interval, all of the players who have not checked remain in the pot.

The most important thing to remember about Poker is that it is a game of skill. The divide between break-even beginner players and big-time winners has very little to do with luck and a lot to do with learning to view the game in a cold, detached, and mathematical way. It is crucial to study your opponents, classify them into one of four basic player types (LAG’s, TAG’s, LP Fish and Super tight Nits) and exploit their weaknesses. After all, a single mistake made by an emotionally driven opponent can cost you a pot or two. The more you play and watch experienced players, the quicker you will develop good instincts.
