isn't regular chess already a 3D game? you have two spacial dimensions (rank and file) and then wouldn't the sequence of turns constitute a temporal dimension?

isn't regular chess already a 3D game? you have two spacial dimensions (rank and file) and then wouldn't the sequence of turns constitute a temporal dimension? maybe the turns are conventionally ignored (and not counted), since all games have them?

Chess also has 3 spatial dimensions. The knight can jump over pieces

  or phase directly through them ;)

  It's probably more 2,5D as jumping is the only "ability" able to use this and even then only temporary.

    > jumping is the only "ability" I assume, then, that your definition of "jumping" includes whatever it is the rook and king are doing when the player castles.

  Jumping is a human approximation for the move, chess in terms of gameplay has no jumping.

  When castling, does the King jump over the Rook, or vice versa?

Good question! The way I think of it, the time dimension isn't relevant because you can make moves because of it. In regular chess, you don't need to keep track of a 3-dimensional game when playing, only the most recent 2D board (and sometimes the one before it for en passant). For that reason, I consider it 2D.

  I get your point, but you also have to keep track of castling rights. If King or Rook have moved at any point (not necessarily on previous move), you can't castle even if they're in their starting position again.

  in addition to V-2's point about castling, there are some other rules in chess that depend on the previous state of the board: https://en.wikipedia.org/wiki/Threefold_repetition https://en.wikipedia.org/wiki/Threefold_repetition https://en.wikipedia.org/wiki/Fivefold_repetition https://en.wikipedia.org/wiki/Fivefold_repetition https://en.wikipedia.org/wiki/Fifty-move_rule https://en.wikipedia.org/wiki/Fifty-move_rule I guess you could argue these are league rules and not part of the fundamental game of chess.

The 'normal move' time dimension is the same as the move back n-boards in time just opposite sense and magnitude.
