Honinbo Shuhaku

Hon'inbō Shūhaku (本因坊秀伯, 1716–1741) was a Japanese professional go player and seventh head of Hon'inbō house. His succession to his short-lived predecessor, in 1733, was irregular, since he had not been officially adopted as heir. He also died young, after a period of intrigue. His greatest match was against Inoue Shunseki.
