Once upon a time a great Sultan of India was ruling over everything except his own all day long boredom. The Sultan was so bored that eventually he got sick from inaction, staying in bed like if he was going die. A Brahmin took pity on his Sultan and invented a game for him: he called it chess. This game made wonders. As soon as the Sultan finished the first game, he started feeling better and soon he was healthy again.
- What award would you like? - asked the Sultan.
- Not more than a single grain of wheat. Please put a grain of wheat on the first square of the chessboard, two on the second square, four on the third and eight on the fourth, double wheat grains for every next square till the 64th square. Whatever the quantity will be, I wish it as an award. - said the Brahmin.
- What a modest request! - smiled the ruler of India. Your request sounds mysterious...
- Solve my puzzle and discover that my invention is priceless! - answered the wise man even more mysteriously.
The Sultan called for his advisors and asked them to solve the puzzle. His scientists started working on it, calculating the numbers and soon realizing that all the wheat in the country would not suffice to pay the award. So the wise man was thinking ahead, made plans and with his mysterious request, he outsmarted the mind of his ruler. In other words, he did exactly what chess is all about. But even more suggestive is the hint of this incident at the richness of chess: the total possibilities of our game exceed the number of atoms in the Universe!
