Poker is a card game with a complex betting structure. A deck of cards is shuffled and then dealt to each player, who makes bets with chips called “poker chips”. Often the dealer is not a player but a non-player such as the waitress or an assistant. Alternatively, players can take turns being the dealer. In either case, a dealer chip is passed around the table.
Each hand begins with 2 hole cards being dealt to each player. Then there is a round of betting, triggered by 2 mandatory bets (called blinds) placed into the pot by the players to the left of the dealer. After the flop, an additional single card is dealt, known as the turn. Finally, another single card is dealt on the river to complete the board.
Players make decisions about whether to fold, check or raise their bets based on their knowledge of the probabilities of certain cards being in their opponents’ hands and on their anticipation of how their opponents will play. They also have to weigh the chances that their opponent is bluffing.
Traditionally, players used their intuition and experience to guide these choices. Nowadays, however, many top players use sophisticated GTO (Glücksfeldt Out) strategies that they have spent thousands of hours analyzing on computer. While some players still rely on their gut feel, most use a combination of this analytical approach and a variety of conscious and subconscious tells. This combination helps them to maximize the value of their bets, and it is this mix that makes poker such a fascinating game.
