najdork
A najdork is a person who thinks they're smart, but they're just learning too much and getting their butt kicked.
He tried to learn the Najdorf and still got checkmated in 3 moves. Najdork for life.
She thought she was a pro because she learned the Najdorf. Nope. Najdork.
He spent all his time on the Najdorf and still lost to a kid. Najdork moment.
