Sometimes the winning idea isn’t to chase an enemy piece away — it’s to invite it in. A decoy lures an enemy piece onto a specific square where something bad is waiting: a fork, a mate, or a fatal skewer. Decoy puzzles train you to see the trap square before your opponent does. The set below is live and pulled from real games; solve a few and you’ll start setting the bait instead of just reacting to it.
How to use this page
- Ask “where do I wish an enemy piece were standing?” Then force it there.
- Decoys are usually sacrifices — offer a piece the target has to capture.
- Missed it? Identify the square you needed the piece on, and why.

What is a decoy, exactly?
A decoy is a move — very often a sacrifice — that lures an enemy piece onto a square where it’s vulnerable. The classic is the king decoy: you sacrifice a piece with check so the king is forced to capture, dragging it onto a square where a knight fork or a mate is waiting. But you can decoy any piece: pull a queen onto a square where it’s skewered, or a rook onto a fork square. The difference from a deflection is direction. A deflection forces a piece away from a job; a decoy lures a piece to a bad square. Think “come here” rather than “get out.” Our guide to the decoy walks through every pattern.
How to spot a decoy (the cues that matter)
- Find the dream square. Ask where an enemy piece — especially the king — would be catastrophically placed. A fork square, a mating square, the end of a skewer.
- Look for a forcing offer. A check the king must capture, or a piece the target can’t refuse, drags it exactly where you want it.
- Set up the follow-up first. A decoy only works if the punishment is ready. Confirm the fork, mate, or skewer is waiting before you sacrifice.
- Watch the king’s forced captures. If a sacrifice checks the king and it has to take, you’ve likely got a decoy — calculate where the king lands.
- Think two moves deep. Decoy, then the payoff. Always calculate the move after the piece arrives on the trap square.
Common mistakes to dodge
- Luring with no trap ready. Dragging a piece to a square is pointless unless something punishing follows. Set the trap before you spring it.
- Assuming the capture is forced when it isn’t. If the target has a way to decline your sacrifice, the decoy fails. Verify the capture is truly forced.
- Confusing it with a deflection. Decoy = lure to a square; deflection = force away from a job. Mixing them up leads to the wrong move.
- Sacrificing more than the payoff is worth. Count carefully: the material you give must be repaid by mate or a decisive gain.

Decoy puzzle FAQ
What’s the difference between a decoy and a deflection? Direction. A decoy lures a piece to a bad square; a deflection forces a piece away from a defensive job. Come here vs. get out.
What’s a king decoy? A sacrifice (usually with check) that forces the enemy king onto a square where a fork or mate is waiting — a favorite way to expose a castled king.
Do decoys always involve a sacrifice? Very often. You give material precisely to make the capture forced. It only pays off when the follow-up wins more than you gave.
