 The pawns are positioned in front of the pieces.The moves of the pieces are identical to those in orthodox chess; a queen or rook may, if it is not obstructed, move any distance round a ring, except that the "null move" of moving a piece all the way round the board and back to its original square is not permitted.A pawn is promoted after moving six squares from its initial position, to the square immediately before the opponent's starting line.
