Sicilian Defense: Najdorf VariationBETA

Developing a piece and overprotecting the e4 pawn. This move is suboptimal because it blocks white's half-open d file and undefends the white knight. However, it is a relatively new try for an advantage in the Najdorf at the top level in which all of the more normal moves have been deeply explored.

The Najdorf Sicilian is one of the most popular variations in all of chess. It is highly theoretical, and leads to extremely double-edge positions with winning chances for both sides. White's lead in development means they can often build up a huge kingside attack, while black has lots of counter-attacking chances on the queenside due to their solid center and flexible pawn structure.
