Invincible: The Games of Shūsaku is a biography of Shūsaku and a collection of over one hundred and thirty Go game records (kifu) compiled, edited, and translated by John Power. Commentary of only eighty games are given and played by Shūsaku, which is framed by a biography of the Go master.
Shūsaku, born as Kuwabara Torajiro, was a Japanese professional Go player from the 19th century. He is known for his undefeated streak of 19-games during the annual castle games, his thirty-game match with Ōta Yūzo, the eponymous Shūsaku opening, and his posthumous veneration as a Go Sage (Kisei). Next to his teacher, Hon'inbō Shūwa, he is considered to have been the strongest player from his era. He was nicknamed Invincible Shūsaku because of his castle games performance.
The first three chapters focus on the life of Shūsaku, Go in the Edo period, and the style that Shūsaku used and popularized. A helpful chronology of the Hon'inbō House, statistics of Shūsaku’s career, and a glossary of game terms are listed in the preface. His life is further explored as Powers frames the games during that particular point in his life and career.
The eighty plus kifu are categorized into six chapters: Shūsaku's Debut (13), The Encounter with Gennan Inseki (2), Heir to the Hon'inbō House (22), The Sanjubango with Ōta Yūzo (23), Unvanquished (20), and Miscellaneous games (58). All games are analyzed rather well and use language that is for a causal player.
Invincible: The Games of Shūsaku is written extremely well. These kifu are reviewed by a number of professional Go players, including Go Seigen, Ishida Yoshio, Kato Shin, Miyamoto Naoki, Kitani Minoru, and others notables. The commentary is very deep and comprehensive and offers many diagrams showing alternative results of certain plays, and how that could affect the outcome. Furthermore, the commentators are able to give precise examples of why certain moves are played and not others and also offer up many alternative scenarios that may have worked better to the benefits of one player or the other. The second section of the book is another fifty-eight non-commentated games for further study.
All in all, Invincible: The Games of Shūsaku is a wonderful commentary of the life, times, and games of Hon'inbō Shūsaku – a definitive reference to the Kisei.
