Games of Cho Chikun in the Prime Minister's Cup

The Prime Minister's Cup was open to players 7 dan or under. It ran 25 terms from 1957 to 1981. Until 1974 the title holder was decided by a single game, but after that by a best-of-three match.

This is one of the few titles that Cho never won. The list of games is complete, with the exception of the preliminary rounds, for which I do not have any data yet.
