Deflection and Decoy: Misdirecting the Enemy
Two Cousins, One Goal
Deflection and decoy are sister tactics: both force an enemy piece to move where you want, not where it should be. Deflection pulls a piece away from an important duty — like guarding a square or another piece. Decoy lures a piece onto a specific square where it can be attacked, forked, or checkmated.
Deflection: Off the Job
Imagine a rook is the only defender of your opponent’s back rank, the row where their king hides. If you can give a check or a threat that forces that rook to abandon the back rank, you may then deliver checkmate there. You deflected the rook from its defensive duty. The usual tool is a forcing move — a check or a capture — the opponent cannot ignore.
Decoy: Come Here, Please
A decoy does the opposite: instead of pushing a piece away, it pulls a piece toward a square. A classic case is a sacrifice that drags the enemy king onto an exposed square where a knight then forks it together with the queen. The king did not want to go there — the decoy left it no choice.
Why Forcing Moves Matter
Both tactics depend on forcing moves: checks, captures, and direct threats that strictly limit the opponent’s replies. If the enemy piece could simply stay put, neither tactic would work. So when hunting for a deflection or decoy, look first at every check and capture you have — they are the levers that move enemy pieces against their will.
Telling Them Apart
A quick memory aid: deflection is go away (off duty), decoy is come here (onto a trap). In real games the same sacrifice sometimes does both at once, so do not worry about labeling it perfectly — just notice that you are steering an enemy piece to a square that helps you.
