What is a deflection?
A deflection forces an enemy piece to abandon the square or piece it is defending, usually by attacking something it wants even more. The defender is not captured, it is distracted — and the moment it steps away, the thing it was guarding collapses. Deflection is the motif behind a huge share of back-rank disasters and mating attacks.
How to spot it
- Identify the single piece holding your opponent’s position together — the one defending the mating square or the key piece.
- Look for checks or captures that force that specific piece to move or capture.
- A sacrifice that only deflects is still winning if the follow-up is forced. Calculate to the end, not to the material count.
The mistake to avoid
Deflecting a defender that had a second job you missed — it moves away and still covers the square from its new post.
Train the ones you actually miss
Solving a motif in isolation is useful, but the tactics that cost you rating are the ones you walked past in your own games. Run a free game review and Chesslume turns your own mistakes into puzzles, so you train the pattern you personally keep missing rather than a random one.
Other tactical motifs
- Fork puzzles — One piece, two targets, and your opponent can only save one.
- Pin puzzles — A pinned piece is on the board but not in the game.
- Skewer puzzles — A pin backwards: the big piece is in front, and it has to move.
- Discovered attack puzzles — The piece that moves is not the piece that does the damage.
- Hanging piece puzzles — The most common way games are decided is the simplest one.
- Back-rank mate puzzles — The pawns that shelter the king are also the walls of its cell.
- Mate in 2 puzzles — Two moves, no escape, every defence covered.
