Queens Indian Defense Fianchetto Variation Puzzle (Rated 1098): Win Material with a Fork — Chess Puzzle with Theory & Hints

This middlegame puzzle is a classic example of using activity and king pressure to win material. Black’s queen and knight coordinate against White’s loose bishop and exposed king-side pieces, creating a tactical fork that forces a favorable trade. The key idea is that a forcing check can pull the king into a vulnerable square while also lining up a direct attack on an undefended piece. In practical classical chess, these moments often decide the game immediately.
