Broke Genius

U.S. chess champion is now ranked No. 2 in the world. Opponents fear he's still getting better.

MINNETONKA, Minn. - This ruthless man is very tranquil. He falls asleep easily around the world in seats unsuited for sleeping. He giggles a child's treble giggle when you don't expect. He asks charming novice questions about baseball. He can speak measuredly at length or speak not at all, while sanguine with either.
