Mate In 2 Puzzle (Rated 1129): Spot Mate in 2 — Back Rank Mate
This chess endgame puzzle shows a classic mating net where the enemy king is boxed in by its own pieces and limited escape squares. In positions like this, the strongest move is often a forcing check that drags the king onto a vulnerable square or removes its last flight square. Even when material is down, active piece placement can create a sudden finish. The key idea is not winning more material, but using coordination to deliver a forced checkmate.
