Poker is a card game played by two or more players and contested over a pot of chips. It became popular early in the 21st century, largely because it was made easier to play online and because television broadcasts of major tournaments brought in large audiences. There are many variants of the game, but they all revolve around betting concepts and the challenge of determining what an opponent has in his or her hand. There is always a risk vs reward calculation when making a bet, and a good poker player is careful to maximize the value of his or her chip investment. He or she also knows when to bluff, but that is an advanced technique best used sparingly.
Poker articles must be well written to appeal to the millions of fans of this popular game. They should include anecdotes and tells (the unconscious habits of a player that reveal information about their hands), as well as plenty of theory.
