Yasunaga Hajime
(1901-1994) Go writer, very strong amateur player.
Although he continued as an amateur, his status was of a professional who didn't claim the title. When he was granted an 8 dan diploma, Go Seigen quipped that it was unclear whether he was an 8 dan amateur or 8 dan professional ( source: John Fairbairn). He played in the World Amateur Go Championship at age 80.
He trained many future professionals.
See Yasunaga's brilliant theory and his book Shin Fuseki-Ho.
Famous for being able to give more handicap stones to amateurs than professionals with a formally higher rank. (source: Go World, issue 13) tderz
