The Berolina pawn moves, without capturing, one square diagonally forward. It captures one square straight forward. (So, it is the converse of a standard chess pawn, which moves straight forward and captures diagonally forward.) Like a
Three-dimensional chess to be more like modern warfare, attack should be possible not only from a two-dimensional plane but also from above (aerial) and below (underwater). Maack's original formulation was for an 8×8×8 board, but after experimenting with smaller boards eventually settled on 5×5×5 as best. Other obvious differences from standard chess include two additional pawns per player, and a special piece (two per player) named "unicorn". The Raumschach 3D board can be thought of as a cube sliced into five equal spaces across each of its three major coordinal planes. This sectioning yields a 5×5×5 (125-cube) gamespace.
