Grunfeld Defense Intermezzo Beginner Puzzle (Rated 1222): Use Intermezzo — Crushing Material Gain

This middlegame puzzle is a classic example of an intermezzo, where the strongest move is not a direct recapture but a forcing tactical shot that changes the order of events. The key idea is to exploit loose pieces, an open file, and a vulnerable queen-side structure to win material decisively. In positions like this, the side to move can turn a simple exchange sequence into a crushing tactical refutation by using tempo and coordination.
