Learn How to Sacrifice: Decisive Material Gain
This middlegame puzzle from the Scandinavian Defense shows a classic attraction idea: a piece is lured onto a square where it becomes vulnerable to a follow-up tactic. White’s active rook and knight create strong king-safety pressure against an exposed black king, while the black queen and bishop coordination leaves tactical weaknesses. The key lesson is that a sacrifice can be correct when it opens lines, removes a defender, and turns activity into a decisive material gain rather than a slow positional edge.
