Learn How to Win with a Discovered Check: Endgame Tactic
This chess endgame is a great example of how a quiet-looking move can explode into a forcing tactic. The key idea is a discovered check: one piece moves with tempo, uncovering an attack from a long-range piece and often creating a second threat at the same time. In classical chess, these patterns are especially powerful when the enemy king is exposed and a rook or bishop is lined up on the same file, rank, or diagonal. The position also shows how active pieces can outweigh extra material.
