King's Indian Defense: Orthodox Variation, Classical System, Neo-Classical Line

The King's Indian Defense: Orthodox Variation, Classical System, Neo-Classical Line is a solid and aggressive opening for Black, aiming to counter White's central pawn structure.

In this opening, Black allows White to establish a strong pawn center with pawns on d4 and e4, while focusing on developing their pieces and preparing for a potential pawn break with e5 or c5. Black's main idea is to counterattack White's center and create counterplay on the kingside, often leading to sharp and complex positions.

White opts for a more classical approach, developing their pieces to natural squares and maintaining a strong pawn center. The Neo-Classical Line is a modern twist on the Classical System, with White's knight maneuvering to e1, allowing for the f3 pawn to support the center and potentially prepare for a pawn break with f4.

Black's typical plan involves playing for the e5 pawn break, followed by the knight maneuver Ne7, aiming to reposition the knight to a more active square. Meanwhile, White's plan is to maintain their central pawn structure and potentially expand on the kingside.

The resulting positions can be highly tactical and require precise play from both sides. The opening is popular among aggressive players who enjoy complex middlegames and sharp tactical battles. It has been employed by many top-level players, including former World Champions Garry Kasparov and Anatoly Karpov.
