King's Indian Defense: Semi-Classical Variation, Hollywood Variation

This chess opening features a solid and flexible pawn structure for Black, aiming for counterplay on the kingside.

The opening is characterized by Black allowing White to establish a strong pawn center with pawns on d4 and c4, while focusing on developing their pieces and maintaining a solid pawn structure. Black's main idea is to play for counterplay on the kingside, often involving a pawn storm with moves like ...f5 and ...g5. The specific variation involves Black developing their knight to c6, which can later be used to support a pawn break with ...e5.

White's setup in this variation is more conservative, with the pawn on e3 instead of e4, which is typical in the main line. This allows White to maintain a solid pawn structure and avoid potential weaknesses that can arise from an early e4 push. White's light-squared bishop is developed to e2, which is a more passive square compared to the more aggressive d3 or c4 squares.

The specific variation is named after the famous chess club in Los Angeles, where many strong players have employed this opening. It is a less common variation compared to other lines in the main opening, but it has been played by several strong grandmasters, including Garry Kasparov and Anatoly Karpov.

Overall, this opening offers Black a solid and flexible setup, with chances for counterplay on the kingside. White's more conservative approach aims to maintain a strong pawn center and avoid potential weaknesses.
