Modern Defense Kotov Variation Puzzle (Rated 1065): Win Material — Discovered Attack
This middlegame puzzle shows how a forcing pawn advance can create a discovered attack and win material by exposing a vulnerable back rank and loose pieces. White’s active rook and queen coordinate against the king side, while Black’s queen and bishop are overloaded and poorly placed. The key idea is that a single tactical thrust can open lines, force the king into a passive square, and leave an important defender undefended.
