Poker is a card game where players compete with one another to have the highest hand. The game usually involves a minimum amount of money, called an ante (amount varies by game; our games typically use a nickel). Once the antes are placed, players are dealt 2 cards and then place bets into a pot in the middle. At the end of each betting phase, the player with the best hand wins the entire pot.

The highest poker hand is a royal flush, which consists of four matching cards of the same rank and five consecutive cards of the same suit. The second highest hand is a straight, which consists of 5 consecutive cards of the same rank in a single suit. The third highest hand is a three of a kind, which consists of 3 cards of the same rank and two matching cards of another rank. The fourth highest hand is a pair, which consists of 2 matching cards of any rank.

To make smart decisions in poker and life, it is necessary to consider all the possible scenarios and estimate their probabilities. While the outcome of a particular poker hand largely depends on luck, players can improve their long-run expectations by acting on the basis of probability theory, psychology, and game theory. To do this, they must take risks if they want to achieve their goals. Pursuing safety, however, often results in missing out on great opportunities where a moderate amount of risk could yield a large reward.
