Stability is crucial
to controlling and delivering power to the ball through the racquet
head. Any small wobble in the racquet during the stroke will, at
high speeds, translate into a very large error. Instabilities are
the most common source of unforced errors in a match. The rollover
animation below is one example of stable movement.

Move the cursor
back and forth over the image and observe how the racquet is advanced.
While it appears that the player is pulling the racquet forward
by the butt, this is actually an illusion. The movement is more
closely related to a boxing punch.

as the player maintains balance through out the stroke sequence.
