Dutch Defense Janzen Korchnoi Gambit Puzzle (Rated 1408): Win Material — Queen Fork Tactic

This middlegame puzzle is a classic example of a queen fork that wins material by exploiting a loose back rank and an exposed king. White’s queen is active on the b7-a8 diagonal, and Black’s pieces are overloaded by the need to defend the king and key central pawns. In positions like this, the strongest move is often a forcing check that also attacks a major piece, turning a tactical idea into a decisive material gain.
