Philidor Defense Nimzowitsch Variation Fork Puzzle (Rated 862): Win with a Fork — Tactical Discovery

This middlegame puzzle is a classic example of a tactical discovery turning into a decisive material win. The key idea is that one piece can move with a direct threat, while also uncovering a stronger line for another piece behind it. That hidden pressure creates a discovered check, and the follow-up fork targets multiple loose pieces at once. In classical chess, these patterns often decide games when the king is exposed and coordination is poor.
