Learn How to Spot Mate in 2: Queenside Attack
This middlegame puzzle is a classic mating net built around a queenside attack and a forcing sacrifice. The key idea is to use a checking move to drag the defender onto a vulnerable square, then finish with a rook-based follow-up that leaves the king with no escape. Patterns like this often appear when the enemy king is boxed in by its own pieces and the back rank or nearby files are overloaded. In classical chess, forcing moves decide everything.
