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.

Playoff

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.
