Among the Japanese Go players in the 1800s, there was an article called ‘Honinbo Shusaku’.
It is considered the best article of its time, and there is a paving stone that was mainly used.

Like the black 7, paving stones made of garlic hair are often placed, and these paving stones are called ‘Shusaku-ryu’.
And the garlic hat move was named ‘Shusaku’s Garlic Hat’.
In modern times, considering Black’s advantage in going first, 6.5 points are given to White as a bonus.
At that time, there was no concept of bonus, so such a defensive move was possible, but in modern times, many people think that since there is a bonus, we need to be more aggressive, so we did not use that move.
however…

And it has been studied again with artificial intelligence and is often used by professionals.

Those garlic caps are being actively used.


The reason is that, according to the cartoon setting, before the ghost (Sai) meets the main character, there is a substitute baduk player first.
Honinbo Shusakura is a setting
In the comics, Sai is the number of artificial intelligence haha.
