I think this should be changed, he is record title holder in Japan, but Lee Chang ho has almost twice as many titles in Korean professional go.
Of course, japanese titles have got higher prize money, and the competition was also higher.
i dont think competition was tougher than what lee chango experiened.
Cho fought against the top players in the world in order to get his titles, Lee Changho was definetately not against such level in many of the earlier titles he took.
Cho has 70 titles now according to Gobase.
