Since the ball must land short of the service line, it is obviously not
possible to overpower your opponent for a service ace--as contrasted to
the services in Squash Racquets or Lawn Tennis.

The most effective service, therefore, is hit as high as possible on the
front wall to a "spot" that will place the ball after bouncing (and your
opponent must wait for your service to bounce on the floor--he cannot
volley it) as high and also as close to the side wall as possible. Your
opponent will have a difficult time hitting the ball well because of its
height and its closeness to the side wall. A great deal of practice and
experimentation will be required before you discover exactly where that
"spot" is, and with what degree of effort you should hit the ball.

The service is hit with a slight cut, which will usually make the ball
grab the wall and hug closer. A semi-overhand, side-spin service is best
employed from the right court, and a sliced underhand shot is used from
the left side (see fig. 6 [Forehand and backhand lob services.]).

For an occasional "surprise" or change of pace, you can vary the service
by hitting the ball somewhat harder right at your opponent. This can be
done either as a straight shot right down the middle (fig. 7 [Service
straight down the middle.]) or at a sharp angle that breaks off the side
wall and lands right at his feet (fig. 8 [In and out service angling into
opponent.]).

In addition, reversed cuts can also throw your opponent off, since you
can make the ball bounce off the floor in the opposite direction than
expected.

Finally, the service is practically the only stroke in the game of Squash
