This is just the same as playing the computer and hitting "Undo" when you get screwed until you find where it all went wrong. Then you play that new timeline and can "Undo" again to create another timeline. This is a cool way to visualize "Undo" in chess.

Well sure. However in this version you can send your queens from the version of the board where you are winning to the boards where you're having difficulties.

The multiple timelines can interact, however.

"Undo chess" is a single timeline that a (human) player can rewind to a previous board state. Movements in time are constrained to moving the board state. Pieces cannot move independently of the board state in time. Additionally, you still play all the timelines that have been created. In 5D chess, the knight moves two spaces in one dimension and one space in another. In a 2d board, this is the description of how a knight moves. In 5d chess, a knight can move one space back in time and two spaces in the Y dimension on the board two one space back in time. That is fundamentally different than Undo chess. Additionally, this puts a new knight on the board timeline that is forked off of the previous move - so there are now three knights. Lastly, as pieces can move through time as well as space, one of the standard wins is a piece that is attacking the king in the past. I had a game where I moved the queen to the same file as the king (which was currently protected) - it was five spaces away. I moved another piece, and then won as the queen was now attacking the king five turns in the past. The timeline for that board is https://slack-files.com/T0VD96U9G-F01A45YRLTG-cf2d776bd3 https://slack-files.com/T0VD96U9G-F01A45YRLTG-cf2d776bd3 . You can see that there is no piece at [T-1, Y+1], [T-2, Y+2], [T-3, Y+3], ... until the king at [T-5, Y+5].

not at all the same. I can mate you by having your king in check in a board in the current timeline, while checking your king 6 moves in the past as well. I can abandon a board where I'm losing, by moving the king to another dimension where it is less threatened.
