Learn How to Spot a Discovered Attack: French Defense Puzzle
This middlegame puzzle from the French Defense Exchange Variation shows how a single tactical trigger can turn a stable-looking position into a winning combination. The key idea is a discovered attack: when one piece moves, it uncovers a stronger line of fire from another piece, often with check or a major material gain. Here, the position also features a pin, a skewer, and a trapped queen, so calculation matters more than static material count.
