Reading
the server is one major skill that the returner can use to
anticipate the upcoming serves. Many people, who play
regularly at the club or recreational level do a lot of talking with
their bodies. You can learn to read this "body language" by looking
for little idiosyncrasies and tendencies. If you have a chance,
scout out your opponent before a match.
And once you know what is
coming, or think you know, the rule is:
Anticipate, don't commit.
It's okay to lean a smidgen or two
in one direction, or to be thinking about playing what you believe
will be a Power Z, but don't commit. If you do, you won't be able to
recover and return the unexpected serve. Remember, a good server
will also be watching your body language too.
