+ White (resp. Black) pawns move one square diagonally north-west: h1 to a8
+ (resp. south-east: a8 to h1).
+ White (resp. Black) pawns capture on the adjacent orthogonal squares either

+ This is natural after rotating the board by 45° clockwise,
+ explaining the name "Diamond Chess".
+
+p All other pieces move like in orthodox chess.
