Shuei-Karigane Jubango
In 1900, Honinbo Shuei and his student Karigane Junichi played their only jubango. Started with Shuei giving 2 stones. Adjusted to B-2 (i.e. Match Handicap System of sen-ni) after game 2. Karigane was beaten back down to 2 stones after game 6. Shuei won the match with six wins to four losses.
It was Shuei's final of eight jubango that he had played since 1870, over the course of the Meiji Era. It was the second of three played by Karigane against the strongest players of his day (Shuei, Shusai and Go Seigen), all of which he lost. Together with Shusai's match against Iwasa Kei, it was the last jubango of the 19th century.
According to Waltheri, the first game introduced two new joseki (or semi-joseki) into recorded professional play. One was the 4-4 Point 3-3 invasion, double hane, counter hane or "3-3 double hane switch". The other was a variation of the 3-5 point low approach, press and crawl (a-c as to ):
In the second game, a very rare variation of the 3-4 point low approach one-space low pincer and keima jump (g in that article's diagram) was played, continuing into an attachment at the 3-3 and a hane in the corner. This was one of only three occurrences of the line in Waltheri, with the first being played in 1896 (by Shuei himself) and the last in 1914.
