I've only heard the term "deflection" used for a situation where a piece is enticed or forced from the defense of a key square/diagonal/rank/file. I would guess "decoy" means the same thing but isn't as widely used.
Edit: Actually according to wikipedia, a decoy is when you lure a piece to a specific bad square, whereas a deflection lures it to any square where it can no longer adequately defend. So a decoy would be a specific type of deflection (if I understood it correctly).
Thats how I understood it when I learned it. Decoying gets a piece to a bad square, generally to capture it later in the line. Deflection just gets them away from defense of a key square/rank/diagonal, not necessarily to put it in danger, but to take advantage when the piece is overloaded, as the Black Queen is on this puzzle.
@ndskykng- The decoy example on wikipedia confirms what you said, that it's the decoyed piece that's threatened. So in the puzzle it is a deflection.
does a3+ do the same thing and is faster?
1. Qb4+ Kg8
2. Qb8+ Qd8
Qxd4# not, ++
No. See post #58
1. Qa3 works too.
But not in three moves.
Couldn't understand the logic, but got it anyway !!!!!
Puedes hacer un ejercicio a ciegas, es decir viendo inmagináriamente la posición: Blancas Re1, Ta1, Th1, Ac2, Ac3, peones h4, g4, g2 Negras: Rg8, Ad5, Cd6, b7, c6, h6, g7, g6. Estan valido los enroques y los peones al paso.
great puzzle. missed first move though
I disagree fellas... ?????????////
Checkmate was inevitable. I would have taken the queen and hoped the other guy/gal made a blunder...ha ha. Actually, now that I look at it again, by taking the queen on the first move, it would have set up a defence for when the pawn promoted. Game would have continued....

Yeah. For one move. Pawn promote, checkmate.
What's your point?
