Discovered Attack Puzzle (Rated 1463): Win with a Discovered Attack — Pin Tactic
This puzzle is a classic middlegame example of a discovered attack combined with a pin. White’s pieces are already aimed at the black king, and the key idea is to move one attacking piece so it uncovers a stronger threat behind it. In positions like this, the opponent’s queen can become overloaded or trapped when it is tied to king safety. The result is often a forcing sequence that wins material with check and tempo, especially in sharp classical chess positions.
