Learn How to Spot Mate in 3: Queenside Attack
This chess endgame-style tactical puzzle is really a forcing middlegame finish: White uses a queenside attack to create a mating net against the enemy king. The key idea is to exploit the alignment of pieces on the back rank and the overloaded defender near the king. Once the first forcing check lands, the opponent is dragged into a narrow defensive line where every reply is constrained. It is a classic example of how a queen and bishop can coordinate to deliver a decisive finish.
