In poker, players place chips into a central pot in a betting round after a complete hand is dealt. While much of the game involves chance, players voluntarily put money into the pot for a variety of strategic reasons based on probability, psychology and game theory. In addition, many players are known to bluff in order to maximize their chances of winning a hand.

Before a hand begins, all players must “buy in” by purchasing a certain number of poker chips. Once everyone is ready to begin, the dealer shuffles the cards and the player on his or her right cuts. The cards are then dealt to each player, one at a time. Depending on the game, the first of a series of betting rounds may then take place.

During a betting round, each player has the option to call (match the amount of the last player’s bet), raise (bet more than the previous player), or fold. Players cannot raise on every hand, and the more information you have before you act, the better decision you will be able to make.

When your turn to act comes up, it is important to remember that the earlier you are in position, the more risk you are taking. This is because players acting later have more information about your hand than those who act early, and can make a more informed decision about whether to call, raise, or fold.
