Gary Kasparov overcame the computer chess champ Deep Thought, wiping out his switched-on opponent in a Manhattan match, but the triumph by the world's top player could be short-lived. Deep Thought has already beaten several grand masters, and a more powerful version could be ready in three years. "Chess is wider than just calculations. You have to use fantasy, intuition and some kind of prediction," said Kasparov. And he's prepared to take on a new, improved computer adversary: "I would have to challenge it in order to protect the human race." That's one move for mankind.
