Happy to see this finally getting some traction on HN. I finally finished all of the puzzles a couple of days ago and I'm confident I'm going to file this one under the same file as Go: Fun to play, but even better to watch more skilled players analyze.
What is 5D chess?

#82I always thought a cool chess variant would be quantum chess where you can move a piece to more than one square and assign a probability to each position. Your opponent could do the same. But I never worked out how it could work from there.
I think this is a really cool idea. Someone seems to have tried something similar here: https://store.steampowered.com/app/453870/Quantum_Chess/

#83Great, now I can suck at chess in 3 more dimensions.
Just wait till somebody invents 5d Go

#84Earlier quoted context omitted.
I can't tell if this is sarcasm, but anyways: obviously an actual chessboard is indeed 3d - as are all physical objects in our world. Yet a chessboard is effectively a 2d space: any piece position is completely defined by a row and a column.
It's true that at the beginning and end of each move, every piece has a specific coordinate in a 2D space, but it is still nice to imagine that knights' moves (and castling) involve travelling through a third spatial dimension. And yes, the pieces themselves are conventionally thought of as volumes in 3D space rather than areas of a 2D plane.
There’s nothing wrong with defining the 2D world such that knights can pass through intermediate pieces or can simply teleport to a new location.

#85From all the descriptions, this is actually 4D, no?
Normal chess is 2 dimensions, plus you have time dimension (3D), plus you have parallel timelines - that always go just one dimension
So it's 4D and not 5D?
edit: yeah it's actually "just" 4D, from the explainer here

Wouldn't the optimal strategy be to just pick the best move in your opinion and assign 100% probability to it? That way it would just turn back into regular chess.

It depends in real life you always have a 3D chess board (+ time dimension) and in some chess UIs you have the option to get a 3D board rendered, like in chessbase https://de.chessbase.com/Portals/All/2017/_eng/products/frit...
Re: What is 5D chess?
#88'From my experience playing a few games on it against decently strong opponents has been that at high levels it becomes "Chess, but it's much much easier to checkmate, and 2~3 times a game some time travel shenanigans happen." The main reason for that is time traveling and dimension hoping come at a tempo disadvantage. When you create a new timeline, you make 1 move, but give your opponent 2 moves. You used your turn…
> You used your turn in the present, and created a new board where it's their turn in the past.
Doesn't it depend on the piece you use? Knights and Bishops seems to be able to move on the board and move back in time at the same time.
Re: What is 5D chess?
#89I bought this game a few weeks ago with a friend and we jumped in without any prior knowledge about the game or how it worked. After about 3 hours we were finally starting to understand the basic principles and I have to say wow, it's an absolute blast to play. Many hours in now we've finally begun developing our own strategies and it's absolutely insane. I have to say that 5D Chess is one of the most creative and in…
What is your opinion on how into the chess one needs to be to get a similar kind of experience out of the 5D chess? Asking as a casual hobby player.

But you actually only play the game in two dimensions, because the pieces cannot move up or down. Normal chess is a game happening on a 2D plane whether or not the representation of the board and pieces is 2D or 3D.
