Comments

  • The Agon Cup allows both amateur and professional entrants, and sometimes the amateurs win their games. A few game records are available [ext] at Go4Go.
  • Jimmy Cha also lost to Ted Ning and Thomas Ko in Fujitsu competitions. It is interesting to note that Michael Redmond only lost to fellow pros when he participated in the N.A. Fujitsu Qualifier - several times to Jimmy Cha, and once to James Kerwin.
