Put the rook on the 7th row (next to the king’s pawns) or cut the king off — then the queen has a mating square.
What you learn here
Queen and rook together are a mating machine: the rook cuts off a whole row or column and the queen gives mate right next to the king, protected by the rook or attacking from a distance.
Chapter 7 — Mate in two: Your first move makes mate unstoppable. The board then plays Black’s best defence — and you give checkmate on the next move.
