Great explanation. Flipping the player to move when there's no legal retraction is kind of the "official chess joke". It appears as Article 15 of the Problem Codex. This is one of the best of 100s of instances of this funny idea. But I would really appreciate, Frank, if you can highlight the composer's name right up front in your screen: you have plenty of space to left or right of the board. There is no IP associated with chess problems, but it's part of the problem culture to always give the composer's name when quoting a problem. This also gives a sense of history which is part of the aesthetic. Please. In this case it's Walter Freiherr von Holzhausen (Akademisches Monatsheft für Schach 1901).

"Mate in one is a term used to describe a position on a chessboard that allows the PLAYER TO MOVE to give checkmate in one move without any previous forced checks or forced moves."

[Wulfy]

Gonna be honest:
Logically deducing it is black's move is kind of nonsensical as impossible positions appear in puzzles with some frequency.

[RGC_animation]

When you said it's Black to move, I was like: Wait, how in the world can Black checkmate White in 1 move?

[PvblivsAelivs]

Well, yes, when you say "find the mate-in-one, " the person is going to assume that the player whose move it is can deliver checkmate on that move.

As much as I want to love this puzzle, I think being intentionally misleading and getting berated for it shouldn’t be surprise. You can’t pie someone in the face and then when they get mad you explain the joke and give them compensation and expect them to not hold it against you. You were obviously fishing for people to get confused, so don’t be surprised when they don’t like the result. Most people go into chess logic puzzles assuming it’s more basic and a simple test of their knowledge, misleading people like this brings them out of their comfort zone so they obviously won’t always like it.

1. While technically true by Chess terminology, I feel like anyone who hears "Mate in 1" will be thinking that the active player will be the one to mate. Saying "Oh, Black moves, but then WHITE Mates" is kinda cheating.

2. This also reminds me of an older Puzzle that requires a DIFFERENT Outside the Box thinking solution, where you use white to capture and promote to a BLACK Knight. Now, that puzzle doesn't work any more due to a rules change, but with some tricky wording, you can still use it for a sneaky puzzle!

I'm so proud of myself for seeing the move order tbh.

I was like: "theres no way black could have gotten there unless white moved la.... wait"

[NexusOfChaos]

i was thinking *literally* outside the box, as if there was some move i could make *off of the board* that was mate in 1

[dajanacoric]

You said to think outside the box..so i assumed it was a chess game with ability to capture your own pieces so i just took white pawn with the queen

[sukotsutoCSSR]

I thought it was black's turn at first since I intuitively thought that position is a little odd. As a beginner level, it feels nice that I actually got that right. Now to translate this knowledge to reverse my losing streak ..

"Acshually, it was blacks move the entire time even though I said it was mate in 1 ☝️🤓"

THis puzzle is like -
How do you drive from London to Paris in 1 hour?
Answer: You take a plane, because you can't drive there in 1 hour, and you have to understand that you can't drive there in 1 hour to solve the puzzle. How cool is that?

[ivanpogildiakov]

It is not respectful to invite people to solve an incorrectly stated problem. A tricky logic puzzle, a problem which requires a non-standard way of thinking, must be stated correctly.

[gilbertjizz]

Technically, it is not mate in one, as the turns ends with black's move. The moves in chess are defined as follows:

Move 1:
{White move} {Black Move}/{Checkmate}

Move 2:
{White move} {Black Move}/{Checkmate}

If its black to play, the turn ends, so it is not mate in 1 move, as a new move starts after black moves. So there is a mistake in the puzzle.

[jarvispoulton]

Ok, mate in 1 means that the person whose turn it is can deliver mate on that move. This is not mate in 1 but it is forced mate.

[kotelnikovmikail]

There's no mate in 1, the puzzle is formulated wrong. I also tested this position on stockfish, it says there is no mate in 1, only mate in 2. This is because 1 move can only be made by white first, and black always makes the move afterwards. You cannot do it in the other direction. If black moves, white's move is considered as the next move.

Here's an example. From the position in the puzzle, assuming that the score is 0-0:
1. ... black_move
2. white_move#
1-0

[Sameer-erwz]

People have been incredibly respectful in the chat here. My immediate honest reaction was “Idiot!”

[goosehead]

this puzzle is really amazing because it is so rare to promote to a knight and give checkmate in the same move

[MarcusBean-vqfe]

0:57 was the time when I thought of a knight under promotion
