French Defense Capturing Defender Intermediate Puzzle (Rated 995): Win Material — Tactical Refutation

This French Defense middlegame is a classic example of tactical refutation through a loose piece and a vulnerable defender. White’s active knight jumps into the center to challenge Black’s structure, and the key idea is that the opponent’s last move has created a tactical weakness rather than a stable position. In positions like this, material imbalances matter, but piece activity and tactical targets can outweigh a temporary material edge. The winning side uses forcing play to convert activity into a decisive gain.
