I'm not sure if it's entirely accurate, but I see some similarities between ASY and Kim/Seo.
Defeating players like them requires both strong mentality and elite physical conditioning. Opponents must stay focused, disciplined, and precise accurate from start to finish, while patiently waiting for the rare moments when they become vulnerable or commit unforced errors.
The problem is that maintaining that level of consistency for an entire match is incredibly difficult.
CYF almost pulled it off. She managed to stay competitive for most of the match, but a few slight inaccuracies in her shots at crucial moments ultimately proved costly. Against players like ASY or Kim/Seo, even the smallest mistakes are often punished.
