Athletes don't always do well, and partner chemistry seems to be a deciding factor as well. We're not talking necessarily about romance (although quite a few have cropped up from the show's pairs), but how they interact as student-teacher and on the dance floor.

The three-night premiere event for the ninth season of "Dancing" begins on Monday, Sept. 21, with two couples eliminated on Wednesday, Sept. 23.

Who do you think has the best chance?
