najdork

A najdork is a beginner learning stuff too hard for their current level.

(This term is most useful in chess, because of its name origins, although it is entirely possible to use it outside it, as long as you are understood.)

To paraphrase, a najdork is a beginner, or intermediate player who is actively learning advanced complicated techniques, meant for advanced and masters, which completely unnecessary and useless at their level, when there exists easier knowledge elsewhere.

A najdork is derived from a combination between the famously difficult variation to understand from the Sicilian Defense, the "Najdorf", and the word "dork".
