Learn How to Pin: Decisive Material Gain
This middlegame puzzle shows how a pin can turn into a decisive material gain when the enemy king is still in the center. White’s queen is active, but Black’s heavy pieces are coordinated to exploit the exposed king and the loose piece on the e-file. In positions like this, the key idea is to use the pin to restrict defense and force the opponent into a sequence where a valuable piece becomes overloaded or trapped.
