3.1 The Kiss of Death
The queen is the strongest piece on the board, but alone she rarely mates a castled king. If she checks from a distance, the king can step aside or a piece can block. If she checks from the very next square, the king simply takes her. The solution is a partner: a second piece that protects the queen on the square next to the king. Players sometimes call this the "kiss of death".
The partner can be any piece — even a pawn — and it does not have to be close. A bishop on d3 protects h7 from five squares away. What matters is the line from the partner to the queen's mating square.
3.2 Building the Battery
Often the partner and the queen line up on the same diagonal or file, one behind the other. This is called a battery. A queen in front of a bishop on the b1–h7 diagonal, or in front of a rook on the h-file, is a typical example. The defender must keep the target square covered at all times; if the defending piece is removed or deflected even for one move, the queen strikes.
When you see your queen and a partner aiming at the same square next to the enemy king, count the defenders of that square. If there is only one, look for a way to remove it — we study this in detail in Chapter 10.

Remember
- Next to the king, the queen needs a partner to protect her.
- The partner can be a bishop, knight, rook, pawn or even the king.
- Queen and partner on one line form a battery. Count the defenders of the target square.
- The epaulette mate shows that the king's own pieces can be its worst enemies.
