The game between Shusaku and Shuwa, 22 October 1851, is the first game between Akira and Sai in Hikaru No Go. Therefore, the pro advising the show must have thought this game to be a classic in some sense. The game is reviewed by Yeonwoo Cho here:

It’s an interesting game historically as it features two classic legendary players. And it’s an interesting game in and of itself because it is from the time before Komi so black (Shusaku) plays more territoriality and white (Shuwa) more aggressively than we are used to seeing in modern games. This is also a prime example of the “Shusaku diagonal” (3-4 move 1 and 4-5 move 7).
