Fascinating article about how the extreme stress of chess tournaments affects the bodies of grandmasters.

At 5-foot-6, Caruana has a lean frame, his legs angular and toned. He also has a packed schedule for the day: a 5-mile run, an hour of tennis, half an hour of basketball and at least an hour of swimming.

As he’s jogging, it’s easy to mistake him for a soccer player. But he is not. This body he has put together is not an accident. Caruana is, in fact, an American grandmaster in chess, the No. 2 player in the world. His training partner, Chirila? A Romanian grandmaster. And they’re doing it all to prepare for the physical demands of … chess? Yes, chess. —ESPN
