Learn How to Crush with Discovered Check: Decisive Material Gain
This middlegame puzzle is built around a forcing tactical sequence where an active rook invades the seventh rank and creates a discovered check against the enemy king. The key idea is that one piece can be used to attack while another line is opened at the same time, turning a strong attacking position into a decisive material win. Black’s king is exposed to checks, and the loose coordination of the defenders makes the tactic work with very little counterplay.
