Learn How to Spot Mate in 2: Mating Net
This middlegame puzzle is a classic example of a forcing mating net: the attacking side uses a check to drag the king into a worse square, then finishes with a second decisive strike. The key idea is not material gain, but coordination of queen, rook, and king pressure. In positions like this, a seemingly active queen or rook can become overloaded, and one forcing move can collapse the defense. Always look for checks first when the enemy king is exposed.
