Learn How to Spot Back Rank Mate: Mate in 2

This puzzle comes from a sharp middlegame in the Modern Defense where White’s active pieces create a direct mating net against the black king. The key idea is a forcing tactical sequence: a checking move that also wins time by creating a fork-like threat, followed by a rook invasion on the open file. Black’s king is boxed in by its own pieces and has very limited escape squares, which makes the back rank vulnerable to a quick finish.
