Learn How to Win: Discovered Attack
This puzzle comes from the Dutch Defense and shows a classic middlegame tactical pattern: a discovered attack combined with a hanging-piece refutation. White’s position looks active, but one tactical oversight allows Black to exploit alignment on the e-file and the exposed king side. In practical classical chess, these moments often decide the game immediately because material and king safety are both in play at once. The key lesson is that active pieces can become targets if they are overextended or insufficiently defended.
