I am standing in front of a food stand deciding to buy a hotdog, when I hear these two guys, owners of the stand, talking about chess. My ears perk up. This is not the usual topic I would expect to hear. Asking the nature of the conversation I learn that in Midieval times when Kings didn't have enough money for a standing army, they would wage war by having a chess player play against their enemy. Each group would put up their best chess player. Whoever won the game would win for the country, and the loser would be conquered.
