French Defense Knight Variation Pin Puzzle (Rated 1339): Exploit a Pin — Kingside Attack

This middlegame puzzle shows how a pinned pawn can become the target of a forcing attack. Black’s pieces coordinate against the white king, using active piece placement, a direct check, and pressure on the same diagonal and file to create a tactical refutation. Even though White has extra material, the king’s safety and piece coordination matter more here. The key lesson is that static material can be outweighed by a concrete kingside attack when the defender is overloaded.
