This problem doesn't work at all for the reasons already given: (1) the e.p. key isn't justified by retro analysis, and (2) the position is illegal. Just one of these reasons would've been enough to spoil the problem but it manages to be doubly faulty. There are plenty of good retro problems showing an e.p. key correctly. Too bad they don't keep getting reposted since they aren't in a popular YouTube video like this one.

The position is completely legal and logical. If two moves back white had played B b2+, it would have been mate if black's e pawn had not been on e7 or e6. therefore, in order for there to be mate in one, black's e pawn had to be on e7 rather than e 6. Consequently, black's e pawn had to move from e7 to e5 to avoid mate by white's bishop on b2.
- Certainly not legal
- Nor logical
- "Consequently(?), black's e pawn had to move..." Nope. Black also could have played f7-f6 with the pawn on e7.
- Of course given the task "mate in 1", d5xe6 e.p. is the only possible solution.
the f pawn was pinned by the rook
It looks like it was crafted under the international rules for composing a chess compilation. Sadly, the World Federation of Chess Composition doesn't seem to have a link to it's pdf of the Handbook of Chess Compositions.
Unless otherwise forbidden due to the construct of the problem itself (that is the board position inherently makes en passant illegal), en passant shall be legal.
Personally. I wish there were a lot more people, especially in America, that had an interest in chess compositions.
There are litetally hundreds of thousands of problems.
I use Jogo's Chess Puzzles for my fix. It has lots of other problem. Runs on Android, not sure about iPhone
Over 124,000 compositions
37 400+ endgame studies.
Plus a ton of stuff from real games.

Glad to hear that you enjoy chess compositions and have heard of the WFCC. But note that WFCC rules specifically forbids e.p. capture as the first move when it can't be proved that the previous move was a P double-step. The rules are found on this page of the WFCC site.
Article 16 – Castling and En-passant capture
(1) Castling convention. Castling is permitted unless it can be proved that it is not permissible.
(2) En-passant convention. An en-passant capture on the first move is permitted only if it can be proved that the last move was the double step of the pawn which is to be captured.

Thanks.
I found the pdf of the handbook finally. It was weird, since it's hosted on sci.fi website. I had that link earlier on my phone, and closed it before the handbook loaded because I thought it was a hostile link.
So it looks like the original problem was cooked, since it would be impossible to prove that the last move had to be a double pawn move. The OP hasn't logged on since 2017. His rating on Chess.com was pretty dubious for wanting to be a chess media star.
He didn't take the time to actually find out how to properly construct a chess composition. If his rating is accurate, I can see why he is unable to have the skills to properly construct even a mate-in-one.
I plugged the position in the Meson corrospondance chess database, and it wouldn't accept it as a legal board position. It had an issue with the bishops.

No worries! The WFCC used to be called the PCCC and you must have a link to their old site. The new WFCC site should have the latest version of the Handbook.
Hi
Another reason it's a terrible composition is that there are chess pieces that have nothing to do with the solution. In a proper composition. Every piece on the board should have a reason to be there that's more than just making the board look like it's cluttered with pieces.

Not true. This is the hardest checkmate in 1.
Guys just admit it. Whoever is saying position is illegal are just re-enacting sour grapes. Sometimes in Chess you DO have to think out-of-the-box and be creative. Not a single person pointed out that "P x P could be a solution if black has just moved that pawn." Fact is that everyone is so mechanically tied up in "figuring" something out that no one picked up on the fact that if its White to move then Black should have moved. So what did Black just play. For me its a wonderful puzzle that forces you to think creatively and I for one will always look at future chess puzzles and try to answer "What could the last move have been". Get over it. Kudos to whoever invented the "trick". Thumbs down to sore losers! Booo!
