Learn How to Win a Fork: Decisive Material Gain
This middlegame puzzle from the Grunfeld Defense shows how a single active rook can create a decisive tactical gain when the enemy king is exposed. White’s pieces are coordinated around the open file, and Black’s king safety is the main weakness. The key idea is not a slow positional squeeze but a forcing sequence that uses check, deflection, and a fork to win material. In classical chess, these tactical shots often decide games when development and king placement are uneven.
