Deflection or decoy? Separate leaving a square from reaching one
Deflection focuses on a defender leaving its job. Decoy or attraction focuses on an enemy piece arriving on a bad square. The same combination can contain both, but the calculation questions differ.
A position to work through
Calculate a candidate continuation without moving the pieces. Look for the tactical idea, consider the opponent’s reply, then compare your calculation with the recorded line.

Ask what must disappear or arrive
For a deflection, name the square, piece or line that loses protection. The defender's destination matters mainly because it no longer does that job. For a decoy, name the destination you want the opposing piece to occupy and explain why that square is vulnerable.
This is a training distinction rather than a rigid naming contest. Different teaching collections may label an overlapping combination differently. Your analysis is useful if it identifies the mechanism, even when a database's motif tag uses another accepted term.
Calculate refusal before celebrating acceptance
A tempting sacrifice often assumes the opponent captures. First ask what happens if they decline and make their strongest forcing move. If you cannot punish refusal, describe the idea honestly as an option that needs further evaluation.
When the capture is forced, check which piece must accept. A queen and a rook taking the same offered piece can lead to very different geometry. The target square only matters if the actual accepting piece is vulnerable to the next move.
Use the distinction to repair your own position
If you are defending against deflection, reinforce the abandoned duty or provide a second defender. If you are threatened with a decoy, preserve an alternative legal response that avoids the dangerous square. These are different preventive measures.
In post-game review, write the tactic as a dependency sentence: 'If this defender leaves, this square becomes available,' or 'If this piece lands here, this follow-up works.' That sentence is more transferable than remembering the sacrifice's visual shape without understanding why it succeeds.
Test every accepting piece, not your favourite
Ask whether the sacrifice still works when the target piece has a different legal capture available. Do not alter a board and present it as a real game; inspect alternatives already present in your exercise. If the idea relies on one particular piece accepting, explain why other captures fail. This prevents proving only your favourite branch while ignoring the defender's actual choice. A good study note contains the reason for refusing or accepting the offer, not just the beautiful move you wanted to play.
Write the leaving-square and arriving-square cases
Mix three deflection and three attraction exercises. Before solving, write either a 'leaves' sentence or an 'arrives' sentence. If both apply, explain both, but identify which one makes the final move possible.
Include a failed sacrifice in your set. Find the refusal or alternative capture that breaks it. Your target is accurate classification after calculation, not speed at assigning a label. Finish by proposing a defensive improvement one move before the combination.
Put the practice into a routine
Where Brass Pawn fits
Brass Pawn supports motif-based tactical practice with local analysis. Use that feedback to test your dependency sentence, rather than treating a motif label as proof. The app does not promise that every attractive sacrifice is sound.
