Nimzo Larsen Attack Fork Puzzle (Rated 1223): Mate in 2 — Bishop-and-Queen Net
This middlegame puzzle is a classic example of a mating net built around king safety and piece coordination. Black’s queen and bishop work together to restrict the enemy king’s escape squares, while the active knight and rook support the attack. Even though White has extra material, the exposed king and loose piece placement make defense difficult. The key idea is to recognize when a direct forcing move creates an unavoidable checkmate pattern rather than chasing material.
