The runners try many ways to keep the mind from interfering with their running. One way to do that, according to Karteek and Patanga, is playing chess. They have set up a chess board near their stall in the dugout and after each mile loop they take a turn in moving their chess pieces. However, after a couple of days, Karteek noticed that someone was moving his chess pieces. To his delight, he discovered that Arun, an avid player himself and fellow 10-day runner, had been moving his pieces. When Arun first noticed the chess board and started playing, he said that all his pain immediately disappeared: such is the power of chess. To accommodate the new player, Patanga and Karteek set up a second chess board. Your move!
