Learn How to Win with a Pin: Middlegame Tactics
This middlegame puzzle shows how a seemingly active defense can collapse when one piece is overloaded. White’s attack is built on forcing moves, especially a pin that restricts the enemy queen and exposes the back line. In classical chess, these tactical motifs often decide the game even when material is already favorable. The key idea is to use pressure on a pinned piece to win the defender and then convert with a forcing check or capture sequence.
