Sekiyama Riichi

Sekiyama Riichi (関山利一, Honinbo Risen 本因坊利仙, 23 Dec. 1909 - 31 Jan. 1970) was a professional, Japanese 9-dan. He was the winner of the 1st Honinbo tournament in 1941. After his victory, Sekiyama temporarily assumed the name of Honinbo Risen. He was a pupil of Suzuki Tamejiro.

Sekiyama tied 3-3 with Kato Shin during the 1st Honinbo title match. Rules stated that in such a case the title would be awarded to the player with the better record during the tournament. Sekiyama Riichi had gone 6-3 while Kato Shin performed 5-4, thus awarding Sekiyama the Honinbo title.

Sekiyama dropped out of the title defense in 1943 against Hashimoto Utaro because of bad health, which effectively ended his career. According to John Fairbairn in Kamakura, Sekiyama "was reckoned to have been capable of becoming a fearsome opponent for Go Seigen later had he not had health problems." Sekiyama won the Oteai tournament, the biggest tournament before WWII, more often than Go Seigen. In 1932 (Jiji Go Tournament, win and continue) , when Go Seigen was on an eighteen game winning streak, Sekiyama stopped him with a three point victory as white.

When the Kansai Kiin was formed in 1950, he changed affiliations to the new organization.

His son (Sekiyama Toshio) and grandson (Sekiyama Toshimichi) both became 9-dans at the Kansai kiin.

Style

Miyamoto Naoki said of Sekiyama's style that:

"...with his intensely serious approach to the game he almost never made oversights. Professionals admired his restrained style of play. [...] Gote no sente was another phrase that typified his style. [...] He played solidly, with an inward strength acquired from his teacher Suzuki, and he quickly mastered the art of winning with black. Next he absorbed himself in studying the games of Meijin Shuei. He claimed this made him a stone stronger, and he became a master with white, too."^[1]
