Kaku Takagawa won the
Honinbō title nine times in a row, from 1952 to 1960, and was subsequently awarded the permanent title of
Honorary Honinbo. He then chose Shukaku as his Honinbō name. He is one of the few Honorary Honinbos. He was known for having a healthy rivalry with
Sakata Eio. This could be seen as Sakata would constantly beat Takagawa from 1959 to 1966 in the finals of major tournaments. Takagawa's books, translated from their original
Japanese, were instrumental in educating Westerners in the ways of Go. He also wrote a series of articles from 1961 through 1977 for the
Nihon Ki-in which was the primary English source of information about Go during that period. These articles were later compiled into
Improve Your Intuition, still considered a valuable guide for Go players. == Style ==
