# Match between Cho Chikun and three new talents

The Igo Club magazine sponsored an uchikomi-type match between Cho Chikun (9p, Kisei) and the three players Yamashiro Hiroshi (8p), Kobayashi Satoru (7p), and O Rissei (7p). The games were played with (handicap, komi) = (0, 5.5), (0,0), or (2,0). Game #i was published in the 1984 issue #i of Igo Club. The games were probably all played in 1983.
