The defender has a job
Every piece that protects something has a task. The king protects the queen, the rook guards the back rank, the bishop guards the square where a pawn wants to become a queen. As long as the piece stays put, the defense holds. If you can force it away, with a move your opponent can't ignore, whatever it was supposed to protect is left without a defender.
That is called deflection. The tool is almost always a forcing move: a check that has to be answered, or a sacrifice that has to be taken.
The king that protects the queen
Even the king can be a defender. Here Black's queen stands on f7, attacked by White's queen, and the only thing protecting her is the king. A rook giving check is enough to break it up.

Away from the promotion square
In the endgame, deflection is often about a pawn that wants to become a queen. Black's rook on b8 stands in the pawn's way. White's rook steps up beside it and attacks it. If the rook takes on c8, the pawn takes back and becomes a queen, and if the rook stays, White takes it on b8.
Deflection and overloading
The two go together. An overloaded piece has too many jobs, and then it is often enough to give it one more. But deflection also works against a defender with only one job, if you have a check or a sacrifice that forces it away. The opposite is the decoy, where what counts is not the square the piece leaves but the square it lands on.
How to find deflections
- Ask what each defender does. What would fall if that particular piece weren't there?
- Look for checks and captures that the defender has to answer.
- Be ready to sacrifice. A rook or a bishop that has to be taken is often the cheapest way to move a defender.

Frequently asked questions
What is deflection in chess?
A move that forces one of your opponent's pieces to leave a square, a file or a rank where it defends something. Usually it is a check or a sacrifice that has to be taken.
What is the difference between deflection and overloading?
Overloading describes the situation: a piece has too many jobs. Deflection is the move that pulls the defender away. They often go together, because an overloaded piece is easy to deflect.
What is the difference between deflection and a decoy?
In a deflection, what counts is the square the piece leaves. In a decoy, what counts is the square the piece lands on.
