Sacrifice Puzzle (Rated 1538): Mate in 2 — Kingside Attack

This puzzle is a classic middlegame mating net built around king safety, piece coordination, and a forcing sacrifice. White’s attack works because the black king’s shelter is overloaded and the defending pieces are poorly placed. When the enemy king has limited flight squares, even a seemingly active rook or queen can become a tactical target. In classical chess, these patterns often appear when one side has a direct line to the king and the other side’s defenders are tied up.
