Scandinavian Defense Marshall Variation Puzzle (Rated 1390): Clear the Defender — Crushing Fork

This Scandinavian Defense puzzle is a classic example of a clearance idea that opens the way for a tactical fork and a long opening pin. Black’s active pieces create immediate pressure on White’s king and loose back-rank coordination, so the key is to notice which defender can be removed to unlock the attack. The position is not about a mating finish; it is about forcing a decisive material gain by exploiting piece activity, king safety, and a vulnerable queen-side rook.
