How Is This Mate In 1? ♖ Tough Chess LOGIC Puzzle ♖ Chess Logic Puzzle

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."

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

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

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.

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"

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

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

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 ..

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

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?

B8 knight is just an amazing move. Blocking the check while allowing the discovered check by the rook and also preventing the king from escaping to a6, just beautiful.

Actually figured it out backwards. I had a hunch that it was a knight promotion, and then I realized that it works if it is black's move. Good puzzle 👍

this is a puzzle that's rather "mate in 1, but mate yourself"

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

Nice try but I've seen puzzles with this trick before😎 Also minor point, at 2:08 Qb7# is technically an alternative mate. I do think you could have shown a few moves in an example line showing how this position could be achieved but it was still a fun exercise

I loved this puzzle because of it's intricacy

This is like puzzling... "How is the murder..." and then... the puzzle owner "Haha, it's suicide...". Probably too much miss-direction to even find it puzzleish. There are some people that enjoy finding lightbulbs in dark rooms...

Since it's black to move, there is no mate in 1. A puzzle designed as mate in 1 means that the attacking turn, black, can mate in 1 move. Basically the point of this puzzle is to pay attention which color to move
