Yamada Kimio's Nihon Ki-in photo

Yamada Kimio (山田 規三生, born 9 September 1972) is a Japanese 9-dan professional.

Yamada won the Oza title in 1997, and challenged Takao Shinji for the Honinbo in 2006. He reached the final of the 5th Samsung Cup in 2000, but lost to Yu Ch'ang-hyeok. In 2006 he became the first player to earn promotion to 9-dan through two hundred cumulative wins as an 8-dan, in the Nihon Ki-in new promotion system. In 2010 he challenged Cho U for the second time in a row. His two elder brothers Yamada Wakio and Yamada Shiho are also professional Go players.

9x9 Go Skill:

He has been considered by Monteo the best 9x9 human go player in history, based on the synthetic tournament coined in The Way to 9x9, by using the data from the MiniGo game records.[FurtherExplanationNeeded][CitationNeeded] In that synthetic tournament, called The 9x9 Grand Slam, he defeated Cho Hunhyun in Quarterfinal, Takemiya Masaki in Semifinal, and Cho Chikun in Final.

Uberdude: You are declaring someone the best 9x9 go player in history based on 3 games? And what is a synthetic tournament?

PJT (2019-08-19) I have to second Uberdude’s comments (and to point out that “coined” above is peculiar English).
