Learn How to Spot a Mate in 2: Discovered Attack
This Vienna Game puzzle is a classic middlegame tactical refutation where White’s active pieces create a direct mating net against the black king in the center. The key idea is a discovered attack: one piece moves with tempo, opening a line for another attacker and forcing the king into a helpless square. Because the king is exposed and Black’s pieces are overloaded or poorly coordinated, the attack becomes decisive very quickly. In classical chess, these patterns often decide the game before material even matters.
