Easy Chess Problem - Number 2

Hello! I'm back again. This puzzle was made because of interesting idea I found in the newspaper, but has nothing in common with this one posted here.
Post the solution-line below. 

Good luck  Be creative!

QxBc5, king takes pawn-e5, Queen takes pawn-d5 with checkmate

e.p. mate in one

QxBc5 is mate for black with h1=Q#

Rxa3 any of the 3 pawns promote = Kb2 no mate but lose queen to bishop

Yah. very easy indeed. My move is e.p. just like heinzie.

Hello indianteacher, my move like heinzie is 1. exd6!! e.p. MATE!

Moves like this should automatically consider. If this is unacceptable then Black wins easily as the threat of ...h1=Q+ is very poisonous!

but we don't know the last move was that pawn move...

It depends on the composer. If he said that Black's last move is pawn to d5 then white mates with 1. exd6 e.p.! But if he rejects the solution then I would say again that: "Black wins easily as the threat of ...h1=Q+ is very poisonous!"

Puzzle like this don't give information black move his pawn 2 square ya?

(because that serious blunder lol)

Asorski & heinzie are right, en passant!  ...d5 1.exd6#

I let you to post innovative solution of this problem. Be creative, probably the most important fact in this puzzle.
By the way, I changed FEN so if you put it into engine, it will show you mate for black. 

Anything than exd6 leads to win for black.

I didn't mention the en-passant rule because then it'd be too easy, sorry. :)

wut>_< y do i miss out

Nice one, i like this puzzle. :D

Hvala! ;)

So not knowing about the e.p. what about Rf-e3+? If Bxe3 then Qxa3 thus releasing the escape square for whites king if h1=Q or f1=Q....white still in difficulty but at least it ain't totally over!! If Black moves his King and not Bxe3 then White should be able to force him to the edge of the board where mate is inevitable.....

@accringtonian
Fighting off 2 queens, a bishop and a rook with a queen and a rook is pretty much over.

You can at least draw if ep isnt possible by saccing a rook and then checking

I'm sorry MSC157 but yet again there's a problem with your diagram because according to the FEN string, En Passant isn't possible !

If you copy & paste it into Game Editor & try that move, it's not allowed.

Here's the FEN for it:-

7r/4Q3/8/2bpP3/4k3/p2R1R2/P2p1p1p/K7 w - - 0 1

(It's the second hyphen I believe, that indicates E.P. is not permissible-it needs to be set to d6)

This is how it should look:-

7r/4Q3/8/2bpP3/4k3/p2R1R2/P2p1p1p/K7 w - d6 0 1
