Poker is a card game played between two or more players and involves betting on the outcome of a hand. There are several variations of the game, but most involve six or more cards and chips. The game is often fast-paced and the players place bets continuously until one player has all of the chips or everyone folds. Players may call a bet, raise it or check (pass on a turn to act).
The goal of poker is to win the pot, the total amount of all bets placed during one deal. This is achieved by having a high-ranking hand or by making a bet that no other player calls. The game is played in homes, casinos, poker clubs and over the Internet. It has become a national card game in the United States and its rules, jargon and culture are well-known.
Jenny Just, a self-made billionaire co-founder of PEAK6 Investments, says that learning poker has taught her lessons about strategic thinking and risk management. It was an eye-opening experience when she first sat down to play with her teen daughter and realized how similar the game is to business.
