Learn How to Back Rank Mate: X-Ray Attack
This puzzle shows a classic back rank mate pattern built around an x-ray attack on the enemy king. The key idea is that the defending pieces and pawns can look active, but one forcing move removes the main defender and exposes the king to a direct mating net. In practical classical chess, these motifs often appear when rooks are lined up on open files and the king has limited luft. The position rewards calculation over material counting.
