Learn How to Spot a Mate in 2: Discovered Attack
This middlegame puzzle is a classic example of a discovered attack turning into a direct mating net. White’s pieces are coordinated around the enemy king, and the key idea is that one forcing move opens a line while also creating a check. The opponent’s reply is essentially forced, because accepting the sacrifice or stepping away both fail to address the threat on the king’s shelter. It’s a strong illustration of how tactical pressure can outweigh material.
