The Spassky Variation is a dynamic and aggressive response to the King's Indian Attack, where Black immediately challenges White's kingside fianchetto setup with an early pawn push on the queenside. This opening is named after the former World Chess Champion Boris Spassky, who employed it with great success during his career.

In this variation, White typically aims to control the center with their pawn on d3 and knight on f3, while Black seeks counterplay on the queenside with pawn advances and piece activity. The pawn structure often becomes asymmetrical, leading to rich middlegame positions with chances for both sides.

White can choose to either accept the pawn tension or release it by capturing on b5, which can lead to different pawn structures and plans for both players. The main idea for White is to maintain a solid central presence and look for opportunities to exploit weaknesses in Black's pawn structure or coordinate a kingside attack.

Black, on the other hand, will try to generate counterplay on the queenside, often involving pawn breaks with c5 or a6, and piece activity along the b-file. Properly handling the pawn tension and piece coordination is crucial for both sides in this opening.

Overall, the Spassky Variation offers an exciting and combative alternative for Black against the King's Indian Attack, leading to complex and strategically rich positions that can test the skills of both players.
