Sakata Eio writes in Killer of Go: ''"Also, there is the matter of the late, great master of the Osaka area, Kubomatsu Katsukiyo. Master Kubomatsu's flair was for creating immense stretches of territory in the center. If one has the opportunity to play out a game of this master of old, it is recommended that one do so."'' Also, he was the first modern player extensively experimenting with tengen opening (see John Fairbairn's article below).
