Scandinavian Defense Modern Variation Mate In 2 Puzzle (Rated 1143): Spot Back Rank Mate — Mate in 2

This middlegame puzzle is a classic king-safety tactic: the enemy king is boxed in, the back rank is fragile, and your active rook and bishop coordinate to force a mating net. In classical chess, these patterns often appear when development leads to open lines around the king and defenders are overloaded or pinned. The key idea is to use a forcing check that restricts the king’s escape squares and sets up a decisive rook invasion on the open file.
