Poker is a card game that requires skill to minimize losses with bad hands and maximize winnings with good ones. It also requires weighing risk against reward. In life, we must make similar decisions without knowing the outcome in advance. In poker, this is called being “aggressive.” It is important to know how to read other players’ betting patterns, including their level of aggressiveness. This can help you decide how to act in a hand, for example, whether to bet or not to bet and how much to bet.

Before the cards are dealt, the game’s rules may require an initial contribution to the pot, called the ante. This contribution can be in addition to or instead of the blind bet. Once all the players have contributed to the pot, the betting phase of the round begins. Players take turns clockwise around the table revealing their cards. The player with the best 5-card hand wins the pot.

In some variants, players are allowed to make additional bets on their own turn, which are known as raises. If you raise the amount of money being bet on your hand, other players can choose to call your new bet or fold their cards and forfeit their chances to win the pot.
