Magnus Carlsen (Black) Puzzle: Use a Pin — Pin Tactics
A pin becomes especially powerful when the pinned piece shields its king. In this position, Black can use the bishop’s active diagonal and the open d-file to increase pressure on White’s center and king. The target is not merely a pawn: the tactical point is that an attacked minor piece cannot move freely without exposing a more valuable unit behind it. This creates a concrete opportunity for decisive material gain while Black’s pieces remain coordinated.
