Learn How to Exploit a Discovered Attack: Tactical Refutation
This puzzle comes from the Nimzowitsch Defense and shows how a discovered attack can turn an active position into a decisive material win. White’s pieces look coordinated, but one tactical shot opens lines against the king and exposes a major piece on the back rank. The key idea is that a forcing move can create multiple threats at once: check, capture, and a revealed attack on an important target. In practical classical chess, these motifs often decide the middlegame before the endgame begins.
