Learn How to Win Material: Discovered Attack
This middlegame puzzle comes from the French Defense, Classical Variation, where piece activity and king safety collide. White’s bishop creates a tactical shot by opening lines against the black king and the back rank at the same time. The key idea is a discovered attack: one piece moves with tempo while another piece suddenly becomes active on a critical target. In positions like this, a small tactical detail can turn a balanced game into a decisive material gain.
