Poker is a game of decision-making, and making the right decisions is essential to winning. One of the most important decisions is deciding whether or not to play a hand. In doing so, you have to determine if your action has a positive expectation, and whether or not you will make money in the long term. Making a wrong decision can cause you to lose money, and making the right one can result in a win.

The first round of the game begins with a deal. In this game, the player to the left of the big blind receives a pack of cards and is responsible for shuffling it. After this round, the other players begin betting. The dealer may be a player or a non-player. Each player has a chance to be the dealer, and he or she may take turns being the dealer. During the betting interval, he or she may shuffle the cards. In the following betting intervals, the dealer is required to offer a shuffled pack to the player to their right. In the following rounds, the player to the right may check or raise the amount of his or her bet.

After the first round of betting, the player with the best five-card hand wins. The remaining players then share the pot. Eventually, a player will run out of money.
