***** Chess game *****

D. Shved (1345) vs Gr. Yunker (1311). Chess Fight Night According to legend, the presumed inventor of Indian chess is a Brahmin named Sissa. He is said to have invented the chaturanga to distract his prince from boredom, while showing him the weakness of the king without an entourage. Wishing to thank him, the monarch suggests that the wise man choose his reward himself. Sissa just asks for some wheat. He invites the sovereign to place a grain of wheat on the first square of a chessboard, then two on the second square, four grains on the third, eight on the fourth, and so on until the sixty-fourth square in doubling the number of grains each time. This request seemed very modest to the sovereign, who was very surprised and amused by the exercise. But the king was never able to reward Sissa: all things considered, he should have been offered not a sack, but 18,446,744,073,709,551,615 grains... or all the Earth’s harvest for about five thousand years !
