ATTENTION: the 3-D CHESS FAQ FILE contradicts this Raumschach page with the following information: 'Pawns promote on the back rank of the opponent's end-level. White Pawns promote on the fifth rank of Level E; Black Pawns promote on the first rank of Level A. Dickins notes that in capturing Pawns must move toward their promotion rank. The '3-D' application of this rule means that a White Pawn on Cc3 can capture on Cb4 or Cd4 (like regular chess) or on Db3, Dd3, or Dc4, but not Db2. (Db2 is upward but backwards -- toward White's back rank instead of toward Black's back rank.)'
NOTE: I have a text-file copy of Bruce Balden's two newsgroup posts on October 8, 1990. I believe that he has accidentally reversed the pawn promotion zones and that the rules originally given on this page are also mistaken. Here is one reason for believing so. Everyone agrees that a pawn on level 'C' must either remain on that level or move to an adjacent level: 'D' for a White Pawn or 'B' for a Black Pawn. But this means that a pawn on level 'C' will never promote (according to Bruce Balden). So I accept David Moeser's pawn promotion zones (the starting squares of your opponent's King, Knights, Rooks) as stated in the 3-D CHESS FAQ FILE.
ALSO: my Raumschach Revised preset has the correct alternation of colors on a (slightly wider) Raumschach board. The initial setup and co-ordinate system match the game information page.
