Learn How to Spot a Discovered Check: Tactical Opening
This Vienna Game puzzle shows how a single forcing move can transform a normal-looking opening into a tactical attack. The key idea is discovered check: one piece moves with tempo, uncovering a stronger line of attack from a bishop or queen. In sharp openings, king safety often outweighs material, so even when one side is ahead, an exposed king can make the position collapse quickly. The lesson is to look for forcing moves first, especially checks that also open another threat.
