Deflection
Forcing a key defending piece away from the square or line it is protecting, even at the cost of material, so a bigger threat can land unopposed.
Key Ideas
- Identify the one defender holding a critical square or piece together.
- Attack that defender — with a threat, a capture, or even a sacrifice — so it must move away.
- The material given up in the deflecting move is usually recouped many times over by the follow-up.
- Extremely common in back-rank mating attacks, where a single piece often defends the mating square.
How It Works
Deflection targets the single piece holding a position together — the one defender guarding a mating square, a hanging piece, or a key pawn — and forces it away from that duty, usually by attacking or capturing it directly.
It is frequently a sacrifice: giving up material to force the defender to move (often to recapture) is well worth it if the square it was guarding is now left open to something far more valuable, like checkmate.
Back-rank mating attacks are the textbook home of deflection: if a single piece is the only thing stopping a rook or queen from delivering mate on the back rank, removing that piece — by any means necessary — wins the game outright.
