Poker is a card game in which players independently try to assemble the highest-value hand of cards-traditionally, to win cash or chips. In the past, this was a purely recreational activity for men only, but in the 21st century it has become increasingly popular among women and men of all ages and backgrounds.

While the outcome of any given hand involves a significant amount of chance, poker strategy is based on mathematics, probability, psychology, and game theory. Indeed, the foundational 1944 book on game theory by mathematician John von Neumann and economist Oskar Morgenstern used poker as an example.

As such, poker requires a high level of discipline. The player’s ego must be managed, and the tendency to overthink and arrive at bad conclusions should be avoided at all costs. It is also important to be able to read an opponent’s betting pattern in order to make the best decision possible.

The basics

Poker begins with one or more players making forced bets (the ante and blind, respectively). The dealer then shuffles the deck, cuts, and deals each player cards one at a time, starting with the player to his or her right. The cards are then either turned face up or down, depending on the variant being played.

The aim of the game is to get a high value hand such as a pair, a full house, or a straight. To do this, the player must play a strong value hand, bet aggressively, and capitalize on mistakes made by opponents.
