Back Rank Mate Intermediate Puzzle (Rated 987): Spot Back Rank Mate — Queen Endgame

This chess endgame puzzle shows how a seemingly simple queen ending can hide a forced mating net. The key idea is that the enemy king has very little room, while its own pieces and pawns restrict escape squares. In positions like this, a forcing check can drive the king onto a vulnerable square where the final mating move becomes unavoidable. It is a classic example of using active queen play to convert a small advantage into a decisive finish.
