the best move in the history of Go

(1)The above Go game was played in the 2020 Go national league match, and it is a huge crisis because Baek cannot build a house on the lower side and the connection between the center and Baekdol is cut off.
(2)Here, Baeki 88 Uisu was the best trick in the history of Go, and there was no way for Baekdols to live except Lee Su.
(3)From Black’s point of view, of course, they have no choice but to catch Deul, but Baek was able to connect by catching three black stones in the center with the sacrifice of 88 in front.
(4)The reason why 88 prosthetic hand is the best skill is because when you first learn Go, you usually learn the shape of Hogu, and the three black stones in the picture above are Hogu. If Baek is placed in A position, you will learn not to put it in A position, but it is the best skill by making a handshake beyond the limit of Park Jeonghwan 9-dan accident.
(5)For your information, even the highest AI at that time did not find the number of 88.
