A short two years thereafter, he had become a disciple of Hon'inbō Dōsaku, the strongest player of his time. He became very strong under Dosaku, eventually reaching 6 dan.

Dōchi became the 5th Hon'inbō in 1702, and Meijin Godoroko in 1721. He served as Honinbō for twenty-five years (1702–1727) and Meijin for 6 years (1721–1727). He played in an international match against a visiting Ryukyuan player, the Satonushi of Yara. He is famous for his brilliant endgame plays, including a classic example of '' semedori'' (forcing an opponent to capture dead stone, exhibited in a 1705 game against Yasui Senkaku. This was in a grudge match, since there had been bad blood between the Honinbos and Yasuis since Yas ...

Jubango
Jūbango (十番碁) is a Japanese term for a Go match consisting of ten games which might be ended earlier if agreed by both players. A decisive victory would result in the opponent being ' beaten down' to a lower rank. A player would be beaten down if he fell behind his opponent by four wins in the net score. This would mean a change in the playing terms corresponding to a handicap suitable for a rank difference of one rank. Some notable historical ''jūbango'' players are Go Seigen (1914-2014), Kitani Minoru (1909–75), Honinbo Shuei (1852-1907) and Hashimoto Utaro (1907-94). These matches were usually spread over long time-periods, with gaps of months possible between games. They were also peripatetic (taking place in different venues). Both of these features make them different from modern mind sports matches, which tend to be held over a short time in a definite location. Modern go title matches have adapted these characteristics of a jūbango. Traditional format Among ...

Castle Go
''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 was a professional Go player. (His surname is occasionally given as Segoshi, but that appears to be a misreading, even if attested by furi ...
