EDEN PRARIE, MN—After having won three consecutive ping-pong matches by increasingly wide margins Saturday, David Richter, 27, adjusted the rules in favor of girlfriend Amy Lindon, 28, to avoid another lopsided victory. "I didn't want her to feel bad, and I actually didn't even want to beat her by so many points anymore," said Richter, who let Lindon hit the ball even if it bounced twice on her side, did not penalize her for serving illegally, and on one occasion tripled her overall score. "Toward the end, I was giving her points just for swinging the paddle in the direction of the ball." Richter won 21-7.
