Ishida Yoshio, the youngest ever Hon'inbo in June 1971

This was Ishida Yoshio’s month, by the end the 22-year-old would hold three titles, youthful success in newspaper tournaments unprecedented before that time.

On June 10-11, in Game 5, he scored an upset victory over Rin Kaihō Hon’inbo to take a 3-2 lead in the title match. Then on June 21-22, in Game 6, he navigated a complicated ōnadare joseki — to become very much in vogue — to lead to the famous exchange: Rin – “Half a point?” “Half a point to the good” replied Ishida and he was Hon’inbo. The counting, under the watchful eye of Sakata Eio, is pictured here. (Game records: Hon’inbo Game 5, Game 6.)

Ishida added the Pro Best 10 to his Hon’inbo and Nihon Ki’in Championship, but it was not without difficulties. Carrying a 2-0 lead in the five game match into the month he stumbled, perhaps under the pressure of the concurrent Hon’inbo match. On June 6, Ishida, known as “The Computer” for his calculating skills, had an AlphaGo Game 4 moment when he retook a ko without a threat – the first time this had happened in a tournament final – and lost by forfeit. He then was defeated by Kajiwara Takeo in Game 4, setting up a decisive Game 5. On June 29, with the Hon’inbo title secured, he returned to form and secured the title. Watching the smiling Ishida is a constellation of pros, including white haired taisha expert Yamabe Toshirō, Awaji Shuzō, Takemiya Masaki and Ishida Akira. Standing on the left is a gentleman who I think might be a pro who regularly attends the European Go Congress – his name escapes me, perhaps a reader can help. (Game records: Pro Best Ten Game 3, Game 4, Game 5.)

On June 21, Murakami Bunshō won the Amateur Best 10 for the fourth time in the event’s 11 year history.
