Indian Defense Discovered Attack Puzzle (Rated 1081): Exploit a Discovered Attack — Decisive Gain
This middlegame puzzle is built around a discovered attack, where moving one piece unleashes pressure from another. The key idea is that the active knight creates a direct tactical threat while also opening the queen’s line to a high-value target. Because the opponent’s pieces are awkwardly placed, the tactic wins material and leaves Black under severe pressure. In classical chess, these motifs often appear when a pinned or overloaded defender cannot respond to both threats at once.
