dang it i couldnt get it

cute first move.....nice

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.

Easy!

good puzzle

does a3+ do the same thing and is faster?

Qxd4# not, ++

pretty easy

No.  See post #58

1. Qa3 works too.

But not in three moves.

  Couldn't understand the logic, but got it anyway !!!!!

tricky

     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... ?????????////
