A decoy is a tactic that forces an opponent’s piece onto a particular square, usually to expose it to capture or to pull it away from a more important defensive task.

The tactic succeeds because most pieces defend more than one point at once. By creating an immediate threat that must be met, you compel the defender to occupy the decoy square and thereby abandon one of its other responsibilities. The side offering the decoy gains time or material once the original target falls.

A common pattern arises on the seventh rank. Suppose a white rook already attacks along the rank while a black knight guards both a mate threat on g7 and a loose pawn on c6. White sacrifices a piece on c6; the knight is forced to capture, the g7 square becomes undefended, and mate follows. The sacrificed material is recovered with interest once the attack lands.

Decoys appear in many guises. They can draw a king into a discovered check, drag a queen away from the defence of a vital square, or place a rook on a file where it becomes vulnerable to a pin. In every case the chosen square reduces the piece’s mobility or defensive value.

Key takeaways

  • A decoy forces an enemy piece onto a chosen square by creating an unavoidable immediate threat.
  • The lured piece must abandon one of its other defensive duties.
  • Typical targets include a king drawn into discovered check, a queen pulled from a key square, or a rook placed on a vulnerable file.
  • Material offered on the decoy square is normally regained once the original target falls.

Frequently asked questions

What is a decoy in chess?
A decoy is a tactic that forces an opponent’s piece onto a chosen square, usually to expose it to capture or to divert it from defending a more important target.
How does a decoy differ from a deflection?
They are the same idea; decoy, deflection, attraction, and diversion are interchangeable names for luring a piece away from its defensive duties.
Can you give a typical decoy example?
A rook on the seventh rank attacks a knight that guards both a mate threat and a loose pawn. Sacrificing on the pawn square forces the knight to capture, leaving the mate undefended.
When is a decoy most effective?
It works best when the lured piece must abandon protection of a critical square or line, such as a mate threat, and the sacrificed material is recovered once the original target falls.

  • Clearance — Clearance is a tactical motif in which a piece moves aside to vacate a square or open a line for a more powerful piece—usually a rook or queen—often gaining tempo by delivering check or creating a threat.
  • Deflection — Deflection is a tactic that forces an opposing piece to abandon a key square or defensive duty, exposing a weakness the attacker can immediately exploit.
  • Discovered Attack — A discovered attack occurs when one piece moves off a line and uncovers an attack from a second piece standing behind it on the same rank, file or diagonal.
  • Discovered Check — A discovered check occurs when one piece moves aside, revealing an attack on the enemy king from a second piece positioned behind it on the same line.
  • Pin — A pin occurs when a long-range piece attacks an enemy unit that shields a more valuable piece or the king on the same line, leaving the attacked unit immobilised.
  • Skewer — A skewer is a tactic in which an attacker forces a more valuable enemy piece to move along a shared rank, file, or diagonal, thereby exposing a less valuable piece behind it to capture.
