Learn How to Use a Discovered Check: Endgame Equality
This puzzle is a classic example of a discovered check built around an advanced pawn. The key idea is that one piece can move with tempo while uncovering a stronger line from another piece, forcing the king to respond. In practical terms, this often turns a material deficit into equality by winning back a major piece or simplifying into a drawable endgame. The position rewards accuracy, not brute force, and shows how tactical resources can outweigh static material.
