Hon'inbō San'etsu
Hon'inbō San'etsu (本因坊算悦, 1611–1658) was a professional Go (board game), Go Go players, player, and second head of the Hon'inbō house. Biography San'etsu was the second Hon'inbō. A minor at the time of Hon'inbō Sansa's death, he inherited a difficult situation since he could not receive the official allowance for the house. Sansa had asked Nakamura Dōseki to act as San'etsu's guardian, and through Dōseki's good offices an annual 30 ''koku'' of rice was negotiated.''Go Monthly Review'' 1963/5 p.53 During his minority the position of head of the Hon'inbō house was in abeyance, so that the house notionally did not exist. He played in an international match, giving Peichin Tsuhanoko of the Ryukyu Kingdom a two-stone handicap, when the latter came to Japan with a Ryukyuan embassy in 1634.http://www.gogod.demon.co.uk/NewInGo/Firsts_intl.htm The high point of San'etsu's professional career came in a challenge match against Yasui Sanchi. From 1645 to 1653 they playe ...

Hon'inbō Sansa
Hon'inbō Sansa (本因坊 算砂, 1559 – June 13, 1623) was the assumed name of Kanō Yosaburō (加納 與三郎), one of the strongest Japanese Go players of the Edo period (1603–1867), and founder of the house of Hon'inbō, first among the four go houses, four great schools of Go in Japan. He was a Buddhism, Buddhist priest of the Nichiren sect, and his original dharma name was Nikkai (日海). Life and career Nikkai was born in Kyōto and became a Buddhist monk, monk at age nine. The name "Hon'inbō", (originally pronounced "Honninbō"), comes from a sub-temple of the Jakkōji temple complex in Kyōto where Nikkai, the first "Hon'inbō", resided. Among his students were the ''daimyōs'' Oda Nobunaga, Toyotomi Hideyoshi, and Tokugawa Ieyasu, the three great "unifiers" of feudal Japan. Nikkai considered the three generals to be "fifth-degree" players (五子, comparable to amateur 4 or 5 Go ranks and ratings, dan), but "diplomacy" was likely a factor in Nikkai's even- ...

Nakamura Dōseki
Nakamura Dōseki (中村 道碩, 1582–1630) was a Japanese professional Go player. Tradition counts him as the founder of the Inoue house. This was in fact a retrospective inclusion, essentially a fabrication of the early nineteenth century by Inoue Gennan Inseki. It accounts for the name Inoue Nakamura Dōseki sometimes given. Nakamura was taught by Hon'inbō Sansa. He was the first Inoue go house leader, and second head of the Meijin is one of the eight titles in Japanese professional shogi, and is the most prestigious title, along with Ryūō. The word ''meijin'' (名 ''mei'' "excellent, artful", 人 ''jin'' "person") refers to a highly skilled master of a certain field ( ... post. He was the second Meijin. He is quite famous for his game against Yasui Santetsu, in which the first play was at a 3–10 point on a side, going against the orthodoxy about starting in a corner.

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 ...

Go Players
This article gives an overview of well-known professional and amateur players of the board game Go throughout the ages. The page has been divided into sections based on the era in which the Go players played and the country in which they played. As this was not necessarily their country of birth, a flag of that country precedes every player's name. For a complete list of player articles, see :Go players. The important dates that this separation is based on are: * The establishment of the Four go houses at the start of the Tokugawa Shogunate. * The demise of the houses in the Meiji Period (end 19th century) followed by their replacement by the Nihon Kiin in 1924. * The start of international tournament Go in 1989 A Japanese census on Go players performed in 2002 estimates that over 24 million people worldwide play Go, most of whom live in Asia. Most of the players listed on this article are professionals, though some top level amateurs have been included. Players famous for ...

Hon'inbō
In the history of Go (board game), Go in Japan, the four Go houses were four major schools of Go instituted, supported, and controlled by the state, at the beginning of the Tokugawa shogunate. (There were also many minor houses.) At roughly the same time shogi was organised into three houses. Here "house" implies an institution run on the recognised lines of the ''iemoto'' system common in all Japanese traditional arts. In particular, the house head had, in three of the four cases, a name handed down: Inoue Inseki, Yasui Senkaku, Hayashi Monnyu. References to these names, therefore, mean to the contemporary head of the house. The four houses were the Honinbo, Hayashi, Inoue, and Yasui. They were originally designed to be on a par with each other, and competed in the official castle games called ''oshirogo''. The houses Hon'inbō The Hon'inbō house (本因家) was easily the strongest school of Go for most of its existence. It was established in 1612 and survived until 1940. Up ...

Koku
The is a Chinese-based Japanese unit of volume. 1 koku is equivalent to 10 or approximately , or about . It converts, in turn, to 100 shō and 1000 gō. One ''gō'' is the volume of the "rice cup", the plastic measuring cup that is supplied with commercial Japanese rice cookers. The ''koku'' in Japan was typically used as a dry measure. The amount of rice production measured in ''koku'' was the metric by which the magnitude of a feudal domain (''han'') was evaluated. A feudal lord was only considered ''daimyō'' class when his domain amounted to at least 10,000 ''koku''. As a rule of thumb, one ''koku'' was considered a sufficient quantity of rice to feed one person for one year. The Chinese equivalent or cognate unit for capacity is the ''shi'' or ''dan'' ( also known as ''hu'' (), now approximately 103 litres but historically about . Chinese equivalent The Chinese ''shi'' or ''dan'' is equal to 10 ''dou'' () " pecks", 100 ''sheng'' () "pints". While the current ''shi' ...

Ryukyu Kingdom
The Ryukyu Kingdom, Middle Chinese: , , Classical Chinese: (), Historical English names: ''Lew Chew'', ''Lewchew'', ''Luchu'', and ''Loochoo'', Historical French name: ''Liou-tchou'', Historical Dutch name: ''Lioe-kioe'' was a kingdom in the Ryukyu Islands from 1429 to 1879. It was ruled as a tributary state of imperial Ming China by the Ryukyuan monarchy, who unified Okinawa Island to end the Sanzan period, and extended the kingdom to the Amami Islands and Sakishima Islands. The Ryukyu Kingdom played a central role in the maritime trade networks of medieval East Asia and Southeast Asia despite its small size. The Ryukyu Kingdom became a vassal state of the Satsuma Domain of Japan after the invasion of Ryukyu in 1609 but retained ''de jure'' independence until it was transformed into the Ryukyu Domain by the Empire of Japan in 1872. The Ryukyu Kingdom was formally annexed and dissolved by Japan in 1879 to form Okinawa Prefecture, and the Ryukyuan monarchy was integrated ...

Two-stone Handicap
Within most systems and at most levels in the game of Go, a handicap is given to offset the strength difference between players of different ranks. Forms of handicaps In the game of Go, a handicap is given by means of stones and compensation points. In contrast to an even game, in which Black plays first, White plays the first move in a game with handicap (after Black's handicap stones have been placed). Handicap stones The rank difference within a given amateur ranking system is one guide to how many handicap stones should be given to make the game a more equal contest. As a general rule, each rank represents the value of one stone. (In terms of points, one stone is considered to be 13-16 points, but this figure is not constant over levels: the more skillful a player, the greater the usefulness of each stone.) For example, a 3 ''kyu'' player gives a 7 ''kyu'' player four handicap stones to allow for an interesting game with roughly equal challenge for both players. If tradi ...

Yasui Sanchi
Yasui Sanchi (安井算知, 1617–1703) was a Japanese professional Go player, and second head of the Yasui house. He became ''Meijin''-''godokoro'' in 1668. It has always been said''Go Monthly Review'' 1963/5 p.54 that this promotion was achieved by a backstairs route, with influence exerted by the head of the Matsudaira clan. A related anecdote has Hon'inbō San'etsu facing down Lord Matsudaira during an earlier official '' oshirogo'' against Sanchi. The Hon'inbō house did not take this lying down. From 1668 to 1675 Hon'inbō Dōetsu played a twenty-game match against Sanchi (they had played in 1649, but after that there was a dearth of competitive games). Dōetsu had the better of it with Black, earning the right to a game with White (as at ''sen-ai-sen Professional Go handicaps were a system developed in Japan, in the Edo period, for handicapping professional players of the game of Go against each other.

Oshirogo
''Oshirogo'' (御城碁 "castle Go") or castle games were official matches of high-level Go played in Japan during the Edo period, usually in the castles of the ''shōgun''. Players were mostly from the four go houses. Matches were played in the ''shōguns presence. With the passage of the years, this became a formality: the players would replay a game that had already been played, and the ''shōgun'' would often be represented by an official, rather than attend himself. The games themselves were, though, bitterly contested, since the castle games had a major effect on the prestige of the four houses. Throughout the Tokugawa shogunate there was an ongoing struggle to take control of the official positions of ''Meijin'' and ''godokoro''. Hundreds of game records of the castle games survive; a large collection was edited by Kensaku Segoe. The game series was suspended in 1862 as the political situation became tense. Apart from one 1863 game between Hayashi Hakuei and Yasui Sanei ...
