There are several mate in 1's. Find one of them and solve the puzzle!

All those "checkmates in 1" are easy. This one is hard. As you can see it's a chess960 diagram. And oh, it's not 1. c5-c6; figure out why.

Liar, it is c6# I tested it and it said it was c6#. Test it happy.png

A couple things wrong with this position:

 

1. There is no mate in 1, since to play en passant we would need to know for certain that black's last move was that pawn move

 

2. The position itself cannot possibly occur in a game. Both sides have all their pieces still on the board, and 7 of their pawns. This means they have each made exactly one capture. Yet white has two pairs of doubled pawns, indicating (at least) two captures. Can't possibly be reached from the starting position.

The reasons sort of go together.

En passant can be legal without an observer knowing what the last move was, but if the position is illegal then there was no last move.

Of course, I'm sure it was never intended as anything but a novelty puzzle anyway.

Even if it were a small typo that there is a pawn on d2, there are other issues. How did the rook get to b7 when blacks area is open and there are a million pieces that can capture it? and the position of the bishops is quite odd.

But what would Black's last move be?

It's probably Black to move.

 

I did consider the king coming from e7, until I realised that both the knight and the e6 rook were both attacking the e7 square at the same time.

 

And that bishop on h8 cannot have been promoted.

So what is the conclusion?

I can't seem to construct a logical sequence as to Black's last move because the non-king pieces have no legal last move and the Black king cannot have moved from a square doubly checked by a knight and a rook from that position.

 

Black could not have made a capture either,

Wait a minute. If it's 960 as per the heading, the last move could have been castling. Hang on...no, that position would have been the position after castling, so it's not possible.

 

With the given position being White to move on standard chess, it would not have been possible to reach that position. En passant or regular capture cxb6 would be the checkmating move.

The solution is dxe6# (en passant).

Ah yes, maybe. Without knowing the previous moves (or at least the previous move) it was mentionewould be impossible to know that.

Dxe6 isn't a check. How is it checkmate? Best I see is nh5+, kh8, qf6#. qf6 from start hangs the knight.

the pawn takes the pawn, and discovers the bishops check

Why does white and black have 5 bishops?
