Learn How to Win Material: Tactical Refutation
This French Defense Exchange Variation puzzle is a classic middlegame example of tactical refutation. White is under pressure because a black knight has invaded an active outpost and several white pieces are overloaded or nearly trapped. The key idea is to use forcing play to simplify the position while winning material, turning a dangerous tactical situation into a decisive advantage. In classical chess, these moments often decide the game before any endgame begins.
