5th Meijin Title 1980
In game 4 of the title match, both the Meijin and the challenger
were in byo-yomi, when Cho asked ko-toriban (turn) to the scorer
(is it my turn to take the ko?) and as he said "yes", Cho played
213, taking a ko without making a ko-threat.
At that time, such question and answer dialogs were customary.
Ishida Yoshio in attendance and Asahi Shimbun immediately discussed
the situation, and Tamura Ryukihei (the game writer) announced
"mu-shoubu" (no game).
The scorer was Hikosaka Naoto (4 dan), who later became Judan.
Cho answered "I did not come to Japan to obtain 5 dan",
when a journalist offered his congratulations when Cho
was promoted to 5 dan some years earlier.
Now he publicly returned home full of honors.
He was invited by the President of Korea, and a photo of the
President and Cho in the Presidential Mansion was published
on the top page of the Korean evening news.
The playoff game between Kato and Cho was played on the 21st of August 1980.
Cho won by 4.5 point
and thus became the challenger.
Players are ordered acording to their results in the previous league.
