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 drive the king onto a worse square, then finishes with a second forcing move. The key idea is not material, but king safety and piece coordination. When the enemy king is exposed and your queen has access to key checking squares, even a materially balanced or slightly worse position can collapse immediately. Look for direct checks first, then follow-up squares that remove escape routes.
