A game of cards and bets played between two or more people. The game has hundreds of variations, but most are fast-paced and involve betting. Players must have a good understanding of probability, as well as how to read and use tells, to be successful.

In a poker tournament, each player makes a mandatory bet (the “ante”), and then the dealer shuffles the cards. The player to the right of each player cuts, and then the dealer deals each player 2 cards face up. Each player may then either raise or call the previous bets, placing their chips in the pot as they do so. Then, the remaining cards are revealed and betting resumes.

Poker became more popular in the early 21st century when it became possible to play the game online and broadcast major events such as the World Series of Poker. It is now played around the world in casinos, card rooms, and even at home.

Self-made billionaire Jenny Just, 54, says she learned a lot about strategic thinking and risk management from playing poker. The skills she gained have helped her to become a very successful businesswoman, the co-founder of PEAK6 Investments. “Poker has taught me so much about being patient and trusting my gut,” she says. “It’s so important in both business and life.”
