Rivalries

Over the course of go history there have been several rivalries, which contested the domination of the national or international scene. In the classical era, such rivalries are mostly known from the Japanese scene. In the years of professionalism, Chinese and Korean masters have taken part in such renowned rivalries.

The Classic Era

• Huang Longshi - Zhou Donghou
• Fan Xiping - Shi Ding'an
• Chitoku - Genjo, the closest rivalry in the classical era
• Jowa - Gennan Inseki, fierce fights on and off the board
