Modern Defense Standard Defense Pin Beginner Puzzle (Rated 1397): Win with a Fork — Decisive Material Gain

This middlegame puzzle is a classic example of tactical refutation built around a pin and a fork. One side has active pieces aimed at the king and queen, while a loose defender becomes the target. The key idea is to create a forcing sequence that wins material by attacking multiple high-value pieces at once. In positions like this, the strongest move often comes from a piece that can both increase pressure and exploit a pinned unit.
