No Limit Texas Hold’em is the most popular poker game of the 21st century. Many factors contribute to its meteoric rise in the early 2000’s: its simplicity (you can learn the game in five minutes), the rise of online poker, the broadcasting of big poker tournaments on television (including the World Poker Tour), and the memorable victory of an amateur player called Chris Moneymaker (you couldn’t make it up!) at the World Series of Poker 2003.
In Texas Hold’em, every player receives two private cards, and must make the best hand possible using their two private cards and the five community cards which are available to every player. To make this five card hand, every player can, according to the situation, use two, one, or none of their hole cards and combine them with three, four, or even five of the community cards. (資料來源)
