King's Indian Defense: Orthodox Variation

The King's Indian Defense: Orthodox Variation is a popular and aggressive chess opening that leads to complex and dynamic positions.

In the King's Indian Defense (KID), a hypermodern opening, Black allows White to occupy the center with pawns and then tries to undermine and counterattack this center later in the game. The Orthodox Variation is one of the main lines of the KID, characterized by the early development of the knight to f3 and the bishop to e2.

In this variation, Black aims to play e5, challenging White's central pawn on d4 and opening up the game for their pieces. White's main plan is to maintain their central pawn structure and expand on the queenside, while Black will try to create counterplay on the kingside.

The positions arising from the Orthodox Variation can be highly complex and double-edged, with both sides having chances for a successful attack. It is essential for both players to be well-prepared and familiar with the typical plans and ideas in this opening.

The KID: Orthodox Variation has been played by many top-level players, including former World Champions Garry Kasparov and Anatoly Karpov. It remains a popular choice for players of all levels, as it offers rich strategic and tactical opportunities for both sides.
