Learn How to Spot Mate in 2: Queenside Attack
This puzzle is a classic mate in 2 built around king safety and a forcing queenside attack. The key idea is that the attacking side uses a forcing check to drag the enemy king into a helpless line, where the reply is essentially forced and the final move delivers checkmate. In positions like this, the strongest move is often not the most materialistic one, but the one that creates an immediate mating net and removes all escape squares.
