Russian Game Puzzle (Rated 1213): Win Material — Pin

This Russian Game puzzle features a relative pin and a discovered attack working together. A seemingly pinned knight can move because the apparent obligation is less important than the tactical gain created elsewhere. By challenging the attacking bishop, White exposes a vulnerable piece and wins material while preserving a strong position. The key strategic factor is Black’s king safety: active pieces have advanced, but tactical coordination matters more than development when a defender is overloaded.
