If you know you are going to play
them in say a club tournament try and get in some matches with other similar
style opponents to get used to the pace of the ball.
Derek says: You often find that if you can extend the rallies, the power
player will gradually run out of steam. Let him make the pace and tire but
don't allow him to rest. Keep the ball in play. Once they lose some pace you
can begin to mix up the play but still extend the rallies. Always play for
the match not just one point or even one game. Once you start to move your
opponent, the power will gradually fade.
