Learn How to Exploit a Discovered Attack: Scandinavian Defense
This puzzle comes from the Scandinavian Defense and shows how a discovered attack can turn a normal-looking middlegame into a decisive tactical win. The key idea is that one piece is doing double duty: it helps defend an important target while also shielding a more valuable piece behind it. When that front piece is forced away, the hidden attacker becomes active immediately, and the position can collapse through direct material gain and king pressure.
