Doubling Cube Inventor is Grand Duke Dmitri of Russia

What is between backgammon, the murder of Rasputin and Chanel 5? A brand new discovery in the ongoing research on history of modern backgammon reveals that Grand Duke Dmitri Pavlovich of Russia is the inventor of the doubling cube, the most important backgammon innovation in the 20th century. Grand Duke Dmitri is also credited for taking part in the killing the controversial "mad monk" and assisting Coco Chanel in the creation of "the world's most legendary fragrance". 

The doubling cube, the six-sided die allowing backgammon players to double, redouble - and if they are bold, redouble again and again - the value of their current game, is doubtlessly the greatest addition to the backgammon game in the 20th century. Up until recently, the doubling cube was thought to be added to the backgammon game in the United States during the 1920s. A recent backgammon news update reveals the identity of the doubling cube inventor: Grand Duke Dmitri Pavlovich of Russia. 

The discovery of the doubling cube inventor was as perplexed and winding as the life story of Grand Duke Dmitri Pavlovich of Russia, who was one of the sole descendants of the Imperial House of Romanov to survive the Bolsheviks' mortification by escaping to London, a worldwide playboy and an active member of the European and American upper class between the two World Wars. 

Grand Duke Dmitri Pavlovich became known of his involvement in the murder of Russian healer/charlatan Rasputin in 1916 (though it is yet to be known whether his involved included pulling the trigger or just providing a car to the escapade), together with his cousin and apparently lover Prince Felix Yusupov. 

He was later famed for co-developing the famous Chanel No. 5 perfume, together with Coco Chanel, with whom he had a short affair. Yet thanks to a thorough research made by the American backgammon player and former World Backgammon Champion Frank Frigo and his 1930 issue of The New Yorker, the Grand Duke (who had died of kidney failure in 1941) will be famed for another historic achievement: the invention of the doubling cube.
