Empty Triangle
In the game of Go, the empty triangle is the most fundamental example of the concept of bad shape. Three stones of one color form an empty triangle when they are placed in a triangle arrangement that fits in a 2×2 square, and when one intersection is left empty. If the triangle is ''filled'' by a stone of the opponent's at the fourth point of the 2×2, the shape is neutral – not necessarily good or bad. The deficiencies of the empty triangle are twofold. Three stones in a straight line have eight liberties, while in an empty triangle they have only seven. This can mean the difference between success and failure in a life-and-death struggle. Also the formation lacks efficiency. In the case cited, the diagonally adjacent stones are tactically connected without the third stone, since the opponent can't prevent them from connecting unless they are ignored for a turn. However even though the empty triangle is a prime example of bad shape, creating one could make sense, or even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Go (board Game)
Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia. The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections (''points'') of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is ''captured''. The game proceeds until neither player wishes to make another move. When ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bad Shape
In the game of Go, shape describes the positional qualities of a group of stones. Descriptions of shapes in go revolve around how well a group creates or removes life and territory. ''Good shape'' can refer to the efficient use of stones in outlining territory, the strength of a group in a prospective fight, or making eye shapes so that a group may live. ''Bad shapes'' are inefficient in outlining territory and are heavy. Heavy groups cannot easily make eye shapes and are therefore good targets for attack. Understanding and recognizing the difference between good shape and bad is an essential step in becoming a stronger player. Shape is not a rule; the surrounding position must always be taken into account. While it is useful for beginners to learn the common good and bad shapes presented here, sometimes a usually bad shape can be the best shape to play locally. This can be true if it forces the opponent to create an equally bad or worse shape, or if it accomplishes a specific tact ...

List Of Go Terms
Players of the game of Go often use jargon to describe situations on the board and surrounding the game. Such technical terms are likely to be encountered in books and articles about Go in English as well as other languages. Many of these terms have been borrowed from Japanese, mostly when no short equivalent English term could be found. This article gives an overview of the most important terms. Use of Japanese terms Although Go originated in China, the current English and Western technical vocabulary borrows a high proportion of terms from the Japanese language because it was through Japan that the West was introduced to Go. Many of these terms are from a jargon used for technical Go writing and are to some extent specially developed for Go journalism. Some authors of English-language Go materials avoid use of Japanese technical terms, and the way they are applied can differ in subtle ways from the original meanings. A few Korean-language terms have come into use (e.g., ''ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blood-vomiting Game
The blood-vomiting game ( ja, 吐血の一局, translit=toketsu no ikkyoku) is a famous game of Go of the Edo period of Japan, played on June 27, 1835, between Hon'inbō Jōwa (white) and Akaboshi Intetsu (black). It is noted for the three ''ghost moves'' that were allegedly given to Jōwa during the game by ghosts, and for the premature death of the go prodigy Akaboshi Intetsu who died soon after coughing up blood onto the board after the game. Selected moves of the game are shown in diagrams. After continually struggling to gain the post of Meijin, Hon'inbō Jōwa had won the title over rival Inoue Gennan Inseki. The rivalry between Jōwa and Inseki began when a game scheduled between the two was cancelled. The game, scheduled for February 18, 1828, was to be played due to Inseki's recent promotion to 8 dan. The game was cancelled by Jōwa's side, who claimed that Inseki did not deserve his promotion but had gained it through intrigue. This led Inseki to attempt to remove J ...

Hon'inbō Jōwa
Honinbo Jowa (本因坊丈和, original name Todani Matsunosuke, 1787–1847) served as 12th Hon'inbō from 1827 and Meijin Godokoro from 1831 until 1839, when he was forced into retirement. Jōwa was born in Nagano, Japan, in 1787. It was said that Jōwa had great strength without equal. Historically he was accorded the title "latter sage" to match Dōsaku who was known as the "former sage". At some point in the Meiji Era this title was transferred to the more popular Shūsaku, as word was spread that Jōwa used the contacts that Hayashi Genbi had within the government to help him attain the Meijin Godokoro position. However, even without playing a sogo, Jōwa's strength was still apparent. Later on in his life, Jōwa also played one of the most famous games in Go history known as the " Blood-vomiting game". Gennan Inseki, a rival of Jōwa's who had seen the coveted position of Meijin godokoro snatched away from him through less than honorable means, persuaded a rapidly impr ...

KGS Go Server
The KGS Go Server, known until 2006 as the Kiseido Go Server, is a game server first developed in 1999 and established in 2000 for people to play Go. The system was developed by William M. Shubert and its code is now written entirely in Java. In Spring of 2017, Shubert transferred ownership to the American Go Foundation. A list of the top 100 players, sorted by KGS calculated rank, is regularly updated and maintained. International tournament games and national championship games are relayed on this server. Monthly Computer Go tournaments are held in the Computer Go room on KGS. The KGS Go Server is distinguished by a kibitz culture. Kibitzes are common and popular in high-level games, and may include off-topic discussions though this is discouraged by the administrators. The two players cannot see kibitzers' comments until after the game. There are several client programs to connect to KGS. ''CGoban 3'' is for normal use, on any system that supports Java. As of 2018, it suppor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
