King's Indian Defense: Fianchetto Variation, Larsen Defense

The King's Indian Defense: Fianchetto Variation, Larsen Defense is a solid and flexible opening for Black, aiming to counter White's central pawn structure while developing pieces harmoniously.

The opening is characterized by Black's early fianchetto of the dark-squared bishop on g7, which exerts pressure on the central d4 pawn. White typically responds with a fianchetto of their own light-squared bishop on g2, creating a symmetrical pawn structure. Black's c6 and d6 pawn moves support the center and prepare for potential pawn breaks with e5 or b5. The Larsen Defense aspect of this opening involves Black developing their light-squared bishop to f5, which can be a slightly unusual move in the King's Indian Defense.

This opening can lead to various pawn structures and middlegame plans, depending on how both players choose to proceed. Black may opt for a pawn break with e5, challenging White's central pawn duo, or b5, attacking the c4 pawn and aiming for queenside counterplay. White, on the other hand, may try to expand in the center or on the queenside with moves like e4, d5, or b4.
