Caro Kann Defense Mate In 3 Puzzle (Rated 1360): Spot Back Rank Mate — Mate in 3
This puzzle is a classic back rank mate pattern hidden inside a middlegame. White’s extra material looks comfortable at first, but Black’s active rook and bishop create a forcing attack against the king’s shelter. The key idea is to use a check that drags the king into a worse square, then bring the rook to the open file for a decisive finish. In tactical positions like this, activity can outweigh material when the enemy king is boxed in.
