TNT_21,
Qxe5 does not mate because the bishop on c4 can block. The move that mates would be Qd6#. (Black queen on e5 is in a pin.)
Hardest mate in 1 puzzles
Sort:
Never mind...Thrillerfan is correct.
Qd6#
@Teddyhead: It can seem complicated at first, but eventually the ability to "see" it as clearly as regular chess arrives.
There is still a problem unfortunately: The position is now illegal. Black made no captures; White captured all missing units with the pawns. (7 to get the structure, 4 more to let the black a- and h-pawns pass.) So what happened to the black f7-pawn? It can't have moved off the f-file by making a capture. The white f-pawn can't have made any capture either, as then you'd be short on captures for the other white pawns. Therefore the black f-pawn can't have been promoted. No captures occurred on the f-file either; therefore, the black f-pawn can't have been usefully captured in any way, and we end up one capture short of the required 11. (To fix: Just move a white pawn to require one fewer capture.)
In other news, Thrillerfan is correct. Further frustrated attempts: 1. Bh4+ Rg5; 1. Qb4+/Qc5+ Kd8; 1. Nf5+/Ng6+ Bxf5/Bxg6; 1. Bd6+ Kf6.

Mate in 1 puzzles are realy esy if your above 1200. Could you post a hard one? You could get it from your games, othe peoples games, compose it,...
Please dont post any comment without a mate in 1 puzzle. If you want to comment on an above mate in 1 puzle, you could, but in the same comment there has to be a mate in 1 puzzle.
I don't think there's such a thing as a "hard" mate in 1 problem. Mate in 2 could possibly be difficult for lower rated players but not for higher rated players. Mate in 3 could definitely be sufficient in difficulty. gl.
Im above 1200 and i didnt solve all the puzzles in this forum, and im sure many people participating in this forum (above 1200) got some puzzles wron.
So it is possibe to make hard mate in 1 puzzles.

How am i suposed to know that the last move of black was moving his pawn?
I think this is a simple enough example of what Remellion was talking about earlier. The last move must have been b7-b5, because there's no other way the previous position could have been legal. (Assuming it's white's turn.)
If your playing in a tournament, if you touch a piece, you have to move it. So lets say your playing with someone and he just moves a bhishop. You wasnt looking at the game and your completely unconscious of it. You look at the board, you see that you could mate if blacks last move was moving his pawn 2 scuares up and you could do en passant to win. You touch that pawn and you have to move it even after he tells you its illegal to do en passant.
Puzzles are for becoming better at chess.
In this case, it can be logically proven without doubt that if the last move was legal, it must have been ...b7-b5. If this were a tournament, and black claims that was not the last move, it is certain that he is lying, or he just made an illegal move himself.
Puzzles are for training the mind, not necessarily for improving your play. Especially the sorts of problems in this thread, they're not really for improving tournament play.
@Teddyhead: This time your position works as intended. Well done.
Another retro mate in 1, this time an old one of mine again (I removed a pawn to make it a little simpler though). Protip: There is only one answer - your job is to figure out whose turn it is. And it can be proven beyond doubt.

I hadn' any previous retro experience. I've solved this one but after struggling an hour or more 
great problem !! I enjoy it. Solution is in the diagram below
Someone consider this as the hardest mate in one puzzle of all time:

Colin20G #91, isn't Qf6 mate?

One position, two puzzles.
1.Nxg8# and 1.Bf5 Nxf6#
Queen takes on e5 and checkmate
Qxe5 is not mate in 1. Black plays Be6.
I believe it's 1.Qa3# because of the pin of the Queen by the Rook on e1, unless I'm missing something.
Just about any move has 1 response to it except Qa3:
1.dxc8=Q+/1.dxc8=R+ allows 1...Bb7
1.dxc8=N+ allows 1...Ke8
1.Nc6+ allows 1...Kf6
1.Qg5+ Black can take with the Q on c1
1.Bg5+ opens up f8 for the King
1.d8=Q is illegal because the Bishop puts the White King in check.
