"Three moves to checkmate and you still don't see it? What a scrub, Oppa♥"

The problem with being the greatest chess player in history is that dying doesn't make you any less arrogant.

After his death, legendary world champion James Fischer wakes up as An Seoyeon, a six-year-old Korean girl with a frightening amount of confidence and a very limited amount of height. Armed with decades of chess experience and a mysterious ability to catch glimpses of people's thoughts, she storms into the modern chess scene with all the subtlety of a queen sacrifice.

Parents are horrified. Rivals are traumatized. Online forums are on fire.

And Seoyeon is having the time of her life.
