Grunfeld Defense Three Knights Variation Beginner Puzzle (Rated 1307): Win Material — Decisive Middlegame Tactic

This middlegame puzzle comes from the Grunfeld Defense and shows how tactical pressure can turn a balanced position into a winning material edge. The key idea is to notice when a queen, rook, or bishop becomes overloaded or pinned, especially in positions with fianchettoed bishops and open files. Here, Black’s active pieces coordinate to force simplification while keeping White’s king and pieces tied down, leading to a decisive advantage rather than a mating attack.
