Poker is a popular card game that combines skill, strategy, and luck. Played with a standard deck of 52 cards, the objective is to win chips or money by forming the best hand or convincing opponents to fold. The game includes multiple variations, such as Texas Hold'em, Omaha, and Seven-Card Stud, each with distinct rules. Players bet based on their hand strength, using tactics like bluffing to deceive opponents. The ranking of hands, from high card to royal flush, determines the winner at showdown. Poker requires a mix of probability calculation, psychological insight, and disciplined decision-making. Both casual and professional players enjoy the game in casinos, home games, and online platforms. Mastering poker involves understanding odds, reading opponents, and managing bankrolls effectively.
