Yesterday’s New York Times ran a front page story on Rumsfeld and how he plays squash:
"Mr. Rumsfeld took up squash more than 20 years ago when he was a business executive. Rather than tricky bank shots off the walls, a move that better-skilled players favor, Mr. Rumsfeld plays with power, hitting the ball hard and ending points quickly. And he relentlessly attacks his opponent’s confidence." Surprise.

Jay Nordlinger has a good interview with him on NRO (and it is essentially reprinted in the dead tree version of the current issues of National Review). "It’s a tough picture. It’s difficult."
