Learn How to Exploit a Pin: Crushing Middlegame Tactics
This middlegame puzzle is built around a powerful pin on the kingside that turns into a forcing tactical sequence. The key idea is that one enemy piece is overloaded: it must protect the king, yet it also sits on a vulnerable square and can be hit with tempo. Once the pinned defender is removed, the position collapses because the king’s shelter is exposed and a second tactical target appears immediately. In practical classical chess, these are the moments where activity outweighs static material.
