Learn How to Exploit a Pin: Interference in Middlegame
This puzzle shows how a seemingly active enemy piece can become a tactical liability when it is overextended and tied to the king’s safety. In the middlegame, the key idea is interference: you force a defender or blocker onto a square where it disrupts coordination, especially along a line connected to the king. The position also features a pin-like restriction, where one piece cannot move freely without exposing something more valuable. That combination often creates a decisive tactical sequence.
