Scotch Game Classical Variation Mate In 2 Puzzle (Rated 990): Spot Back Rank Mate — Mate in 2
This middlegame chess puzzle is a classic back rank mate pattern: the enemy king is boxed in by its own pieces, so a forcing check can drag the defender away and leave the last rank vulnerable. The key idea is that the queen can be used as a decoy to remove the main defender, after which a rook delivers the final blow. It is a short, forcing combination that rewards calculation over material counting.
