趙治勲
Cho continued winning several titles, including the Paewang in 1977, a title he defended sixteen straight times until 1992. In 1980, he held nine titles simultaneously: Guksu, Myungin, Wangwi, Kisung, Paewang, Kiwang, Daewang, Jaewang and the Baccus Cup. Cho repeated this twice, in 1982 and 1986, winning ten and eleven titles respectively. Despite winning several titles, Cho wasn't considered the best Korean player at the time. Instead, the media favored Cho Chikun, a Korean-born 9 dan professional in Japan. In 1980, Cho Chikun visited South Korea after winning the Meijin title and the two began a friendship match consisting of two games. The two game series was played on 31 December 1980 and 2 January 1981 with Hunhyun losing both games. From 1981 until Hunhyun's loss in the 8th Samsung Cup, Cho Hunhyun didn't lose a match to Cho Chikun.
