“Oops, I didn’t even see that move.”
“I misread that.”
“Wait a minute, that stone moved!”
I often find myself saying something like this when I lose a game. As I have mentioned previously, I believe that a lot of games at my level are lost because of simple reading mistakes. Reading Go moves in situations you’re unfamiliar with can feel like trying to read a challenging book in a different language or dialect, but like reading a book, it is something that becomes better with practice.
