Name:
The word Go is a short form of the Japanese word igo (囲碁; いご), which derives from earlier wigo (ゐご), in turn from Middle Chinese ɦʉi gi (圍棋, Mandarin: wéiqí, lit. 'encirclement board game' or 'board game of surrounding'). In English, the name Go when used for the game is often capitalized to differentiate it from the common word go. In events sponsored by the Ing Chang-ki Foundation, it is spelled goe.
The Korean word baduk (바둑) derives from the Middle Korean word Badok, the origin of which is controversial; the more plausible etymologies include the suffix dok added to Ba to mean 'flat and wide board', or the joining of Bat, meaning 'field', and Dok, meaning 'stone'. Less plausible etymologies include a derivation of Badukdok, referring to the playing pieces of the game, or a derivation from Chinese páizi (排子), meaning 'to arrange pieces'.
History:
The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan, referring to a historical event of 548 BCE. It is also mentioned in Book XVII of the Analects of Confucius and in two books written by Mencius (c. 3rd century BCE). In all of these works, the game is referred to as yì (弈). Today, in China, it is known as weiqi (simplified Chinese: 围棋; pinyin: wéiqíⓘ; Wade–Giles: wei ch'i), lit. 'encirclement board game'.
Go was originally played on a 17×17 line grid, but a 19×19 grid became standard by the time of the Tang dynasty (618–907 CE). Legends trace the origin of the game to the mythical Chinese emperor Yao (2337–2258 BCE), who was said to have had his counselor Shun design it for his unruly son, Danzhu, to favorably influence him. Other theories suggest that the game was derived from Chinese tribal warlords and generals, who used pieces of stone to map out attacking positions.
In China, Go was considered one of the four cultivated arts of the Chinese scholar gentleman, along with calligraphy, painting and playing the musical instrument guqin. In ancient times the rules of Go were passed on verbally, rather than being written down.
Rules
Aside from the order of play (alternating moves, Black moves first or takes a handicap) and scoring rules, there are essentially only two rules in Go:
Almost all other information about how the game is played is a heuristic, meaning it is learned information about how the game is played, rather than a rule. Other rules are specialized, as they come about through different rulesets, but the above two rules cover almost all of any played game.
Although there are some minor differences between rulesets used in different countries, most notably in Chinese and Japanese scoring rules, these differences do not greatly affect the tactics and strategy of the game.
Except where noted, the basic rules presented here are valid independent of the scoring rules used. The scoring rules are explained separately. Go terms for which there is no ready English equivalent are commonly called by their Japanese names.
Basic rules
The two players, Black and White, take turns placing stones of their colour on the intersections of the board, one stone at a time. The usual board size is a 19×19 grid, but for beginners or for playing quick games, the smaller board sizes of 13×13 and 9×9 are also popular. The board is empty to begin with. Black plays first unless given a handicap of two or more stones, in which case White plays first. The players may choose any unoccupied intersection to play on except for those forbidden by the ko and suicide rules (see below). Once played, a stone can never be moved and can be taken off the board only if it is captured. A player may pass their turn, declining to place a stone, though this is usually only done at the end of the game when both players believe nothing more can be accomplished with further play. When both players pass consecutively, the game ends and is then scored.
