Poker is a game of betting that can be played between two or more players. Each player starts with five cards and can either check, call, raise, or fold. The strongest hand wins the pot of money. The game has many mechanisms that allow players to misinform other players about the strength of their hands, such as bluffing and raising bets. Players may also signal other players to fold before the “showdown,” where all remaining players reveal their hands.
In the early years of poker’s rise, tens of thousands of amateur players invested small chunks of their income to play it. These amateurs created a pyramid that filtered upward to a smaller group of professionals who took the game much more seriously. This structure made poker a lucrative business that attracted professional investors and generated tremendous profits for those at the top.
