Learn How to Win a Piece: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack combined with a tactical refutation. White’s active bishop creates a forcing check that also opens lines against the black queen and rook coordination. The key idea is not just the check itself, but the hidden threat behind it: once the king responds, White can exploit the overloaded pieces and win material through simplification. In practical classical chess, these motifs often appear when king safety is compromised and one piece is pinned or overworked.
