Remember to smile...
very funny key. Perhaps solvable by the book/rule 1: "Make the dumbest move available!".

Was easy for me. 1. Find a way to make a double-check. 2. Find a way to mate if King moves out of double check.

How come?
Why doesn't he take the Queen?

Never mind!
I see where that does not matter in the end.

Why not.....?
What about 1.Qd3 Qxd3 2. Rf4 ++ ??

@ id= smikal11 :
1Qd3? is one of the better tries and is refuted by 1...Ke5!.
The other try 1.Qf2+? (>2.Rf4#) is also interesting. Spot the refutation!.

"Dumbest move possible"?
@donnaciara: the first thought that occurred to me was 1. Qc2, daring Black to take it with the pawn, which of course does not stop the mate by 2. Rf4#. Unfortunately this is foiled by 1...Ke5.

I finally solved it by reasoning:
1...Ke5 can be met by 2. Qf4, but only if the Q has access to f4.
1...Qe4 can be met by 2. Nc6, but that requires the white W to be guarding c4.
Therefore, if the key move is indeed a Q move, it must preserve access to both f4 and c4, which points to the correct square it must move to.
