Learn How to Pin: Winning a Queen
This middlegame puzzle is built around a powerful pin on the queen and the king’s exposed position. White’s pieces are active, but Black can exploit the alignment of the white queen and bishop to create immediate tactical pressure. The key idea is that a pinned piece can become overloaded, especially when another attacker joins the attack. In positions like this, a quiet-looking developing move can hide a forcing sequence that wins material and turns the game decisively in Black’s favor.
