Learn How to Spot Discovered Attack: Tactical Refutation
This puzzle is a classic middlegame tactical refutation built around a discovered attack. One piece moves with tempo, uncovering a stronger attack from a hidden piece and forcing the opponent into a losing sequence. The key idea is that the exposed king and loose back-rank pieces cannot both be defended once the tactical shot lands. In positions like this, material balance matters less than coordination: a single tactical break can turn a slightly better position into a decisive win.
