Berolina Chess

Chess variant

Chess variant where pawns move in a reversed way: they move diagonally forwards and capture orthogonally forwards.

Otherwise the rules of chess apply, with the following difference:

Pawns can also make double-move from their initial fields, which means that they can move two fields in the same diagonal direction.

Pawns promote in the same way as in chess, i.e. when they reach the opposite side of the board.
