Ruy Lopez Sacrifice Beginner Puzzle (Rated 903): Spot a Mate in 2 — Back Rank Mate
This middlegame puzzle is a classic forcing sequence built around king safety and piece coordination. White’s queen is active near the enemy king, but Black has a hidden tactical resource that turns the tables immediately. The key idea is to exploit the alignment of the queen, rook, and king so that a capture becomes a forcing check, and the follow-up leaves no escape squares. In classical chess, these patterns often appear when one side’s back rank is weak and the opponent’s pieces are overloaded.
