Hosai Masao - Two Ladders Mirror Go
Keywords: Culture & History
This game, played between Sugiuchi Masao (9p) and Fujisawa Hosai (9p), involves a mirror go where two ladders were played almost all the way to the end.
It is mentioned in Kageyama Toshiro's Lessons in the Fundamentals of Go as a game that will "go down in the annals of professional play as an all-time freak".
