American Go E-Journal

“Bob Ryder was 48 at the time of this tournament (From the Archives: The First International Amateur Go Tournament 1963),” writes Terry Benson. “He became one of the first western 5-dans and was president of the AGA in the 60s and early 70s. He was also a part of the Bell Labs research team which developed the transistor.”
And in a related note, Adrian Petrescu has transcribed the game between Robert Ryder and Go Seigen, saying “I thought you might find it useful for those who want to add another Seigen game to their databases.”
