Poker is a card game played by two or more players and involves betting in which the object is to win the pot, the sum of all bets placed. The game can be played with any number of cards but is most commonly played with six. It can be played in many variants, but most involve two mandatory bets called blind bets made by the player to the left of the dealer and a series of community cards dealt face up in three stages – a flop, turn, and river.

While the outcome of any given hand involves some element of chance, long-run expectations are largely determined by actions chosen by players on the basis of probability, psychology and game theory. Winning hands are more valuable than losing ones and the objective is to maximise these profits by minimizing losses on losing hands.

A big part of the appeal of poker is in its bluffing aspect. There are many different strategies to bluff, including body language and facial expressions. This by-play is a major component of what makes the game interesting and what sets it apart from other card games. Every good poker player has tells – unconscious habits or tics that reveal information about their hand. These can be as simple as a flinch or a smile. This is known as “reading the table.” This is the essence of reading a poker game and is what makes it compelling for millions of people worldwide.
