Corridor Mate Puzzle (Rated 1135): Spot Mate in 2 — King Safety

This puzzle is a classic example of a forcing mating pattern in the middlegame, where king safety outweighs material. White’s heavy pieces coordinate to create a direct attack on the exposed king, and the key idea is to use a checking move to restrict escape squares before delivering the final blow. Positions like this reward pattern recognition: when the enemy king is boxed in and your pieces are active, a short tactical sequence can end the game immediately.
