Honinbo Shusai (9p) vs. Go Seigen (5p) 2020-06-16
An exciting match between Go Seigen and Honinbo Shusai in the year 1933.
The game caused quite the sensation because Seigen used a very unusual opening with his first three moves being 3-3, Hoshi and Tengen. Because of this, the match was one of the deciding factors that pushed the Japanese Go community to re-evaluate the Go opening theory at that time and made the "Shin Fuseki" movement way more popular!
However, in the current age of AI analysis using Tengen as part of the opening has lots a lot of popularity since it allows the opponent to take one additional corner or the first attack. Who knows what it will be like 100 years from now? :)
