Mate In 3 Puzzle (Rated 1411): Mate in 3 — Opera Mate
This puzzle is a classic opera mate style finish in a middlegame setting, where the attacking side uses forcing moves to drive the enemy king into a mating net. The key idea is not raw material, but coordination: a rook swing, a pinned defender, and a final checkmate pattern that leaves the king with no escape squares. In chess endgame terms the position is not an endgame at all, but the tactical logic is the same: every move must be forcing and precise.
