Ogawa Doteki (道的, 1669-1690) was a pupil of, and heir to, Honinbo Dosaku. Due to his quick growth in go strength, young age and untimely death he has been considered one of go's great lost prodigies.
Doteki was born in Ise Matsuzaka, Japan in 1669. His Go talent was recognized at an early age and, thus, he was sent to Edo to become a disciple of the Honinbo house.
His developed rapidly, reaching 6-dan by the age of 13 and becoming the heir to the Honinbo house at 15 (1684). The following year, he began playing in the Castle Games and was promoted to 7-dan -- awarding him a ten-fold monetary allotment from the government.
One day, Godokoro Dosaku decided to test Doteki by playing him two, even games. The result was a tie, with both players winning a game by one point as Black. However, it's uncertain whether the result was contrived by Dosaku, a common tactic among strong teachers in classical go. Nevertheless, Doteki's strength has been referenced in many texts and by many professionals. For example, Go Seigen once said, in an interview, that Doteki was the greatest genius in the history of the game.
