Honinbo Shuhaku

Hon'inbō Shūhaku (本因坊秀伯, 1716–1741) was a Japanese professional go player, and seventh head of Honinbo house. His succession to his sort-lived predecessor, in 1733, was irregular, since he had not been officially adopted as heir. He too was destined to die young, and his time was marked by intrigues.
The major match in which he was involved was against Inoue Shunseki.
