OK lets reference the rules at:
|Passive Moves||Capture Moves|
|White Pawn||straight-forward or straight-upward||diagonally forward or diagonally forward-upward|
|Black Pawn||straight-forward or straight-downward||diagonally forward or diagonally forward-downward|
(Please understand that the forward direction is relative to the initial placement of one's pieces, whereas the upward and downward directions are absolute.)
According to the above chart, a White Pawn at Ac2 can move to Ac3 (as in 2-D chess) or Bc2 and capture at Ab3, Ad3 (as in 2-D chess), or at Bb2, Bd2, and (according to some) at Bc3, although I personally do
not like this variant. [Please note that Anthony Dickens supports the
Bc3 move in A Guide to Fairy Chess.]
Pawns promote on the last (or fifth) rank, which is the far side of level A and level B for White, and the far side of level D and level E for Black. There is no 2-step initial move in Raumschach, thus no
en passant capture.
Now I have always played following that chart above, but I see that the text below describes a pawn capturing three dimensionally sideways "a White Pawn at Ac2 can move to Ac3 (as in 2-D chess) or Bc2 and capture at Ab3, Ad3 (as in 2-D chess), or at Bb2, Bd2" although the chart says "diagonally forward or diagonally forward-upward".
I have always played with diagonal forward-upward (or for black downward) and never with the sideways capture described above (but I am not adamant about this).
The issue you bring up is the "and (according to some) at Bc3, although I personally do not like this variant. [Please note that Anthony Dickens supports the Bc3 move in A Guide to Fairy Chess.]"
From what you say above you agree with the rule against forward capture altogether?
Do you have any thoughts on the impact this makes on a game? I can see that a pawn can easily make it within two moves to Cc3 and threaten the opposing pawns in just two moves. Is that the issue?
Yes I think we can agree on the rules, http://www.chessvariants.com/3d.dir/3d5.html using the chart rather than the text below it and with the 5 cell promo zone.
BTW I have only played a handful of games a few years ago with my son, although I have played Millennium Chess (8x8x3) and before that Chess Cubed (almost the same game) since I was a child.

I don't really have a clue how the different ways to capture might affect game play. I've never played Raumschach before. My concern for now is just to make sure we agree on the rules before we get involved in the game.
I also wanted to use the web page you reference, until I noticed that it was less than clear. As you point out, the text after the chart contradicts the text in the chart. Since you have played according to the text in the chart, we can go with that. So, using my example of a black pawn on Cc3, it can capture at Cd2 or Cb2 like a 2-d bishop on the same level, and like a unicorn when capturing a piece on the level below, at Bd2 or Bb2. It will not be able to capture on Bd3, Bb3, nor Bc2. I hope this is the way you like it.
You might like to look at the discussion page for that rules page, at
That's where I discovered the black unicorns and bishops were set up incorrectly (now corrected in the image at the top of this page), and read different interpretations on how pawns should capture and promote. Some players think the promotion zone should be larger than just one rank of five cells. So, I could enlarge the promotion zone if you would like.
Just checking to see if you are out there...
