Learn How to Mate in 2: Queen Sacrifice
This middlegame puzzle is a classic example of a forcing mating attack built around king safety and piece coordination. White’s queen is able to invade the kingside because Black’s king has a weakened pawn shield and limited escape squares. The key idea is to use a forcing check that drags the king into a worse square, where the follow-up mate becomes unavoidable. Even though Black has material advantage, active threats can outweigh material when the king is exposed.
