Learn How to Pin: Decisive Material Gain
This middlegame puzzle is built around a powerful pin on the king’s shelter. The attacking queen creates immediate pressure on the exposed king, while a rook joins the attack from an open file to keep the defender tied down. White’s pieces are awkwardly placed, and the pinned bishop cannot freely respond to the threats. In positions like this, the side with the initiative often converts by forcing the king into a worse square and then increasing pressure with a rook on the same line.
