Grunfeld Defense Brinckmann Attack Puzzle (Rated 806): Win a Fork — Decisive Material Gain

This middlegame puzzle is all about tactical awareness when the enemy king and loose pieces are vulnerable at the same time. White’s active knight creates a forcing check that also targets a key defender, turning a simple-looking position into a decisive material gain. The idea is to use a forcing move to improve your piece activity, expose the king, and win a major piece or queen by exploiting hanging pieces and poor coordination.
