Mate In 2 Puzzle (Rated 439): Back Rank Mate — Chess Endgame Pattern

This chess endgame puzzle is a classic back rank mate pattern, where the enemy king is trapped by its own pawns and a rook invasion becomes decisive. Even though Black is materially ahead, White’s active rook and open files create a tactical shot that overrides the static evaluation. In classical chess, these positions reward calculation over material counting, especially when the king has no luft and the back rank is vulnerable.
