Chess isn't often thought of as dramatic, but last week the World Chess Championship came to a tense, fast-moving conclusion as defending champion Magnus Carlsen of Norway, ranked No. 1, defeated No. 9--ranked Sergey Karjakin of Russia to retain the title. Karjakin, a defensive specialist, held Carlsen even through 12 full-length matches and two of four rapid tiebreaker games, all of which played out over 19 days. "It was refreshing to play a bit faster after all these weeks," Carlsen said. His win also came with a bit of baller-style swagger in the NBA-logo socks he wore, the only clean ones he had left. "Socks are not the priority," Carlsen said. "They can become scarce, and I got these as a gift before the tournament, so I thought, Why not?"
