When you have the serve, you are in the front court, your opponent is as far away from the front wall as it is possible to be, you have the ball in your hand, and you can drop and hit a wide variety of shots. The server has every advantage. Try not to waste this opportunity.
Your goal as the server is to (1) ace your opponent for a point, (2) generate a weak return, or (3) generate a defensive (ceiling ball) return. Obviously an ace is preferable, but aces are low percentage shots. The second best outcome is a weak return that you, since you are in front of your opponent (who is in deep court), have a good chance to kill. This is the three shot rally. It is almost as good as an ace. If your opponent hits a ceiling ball, then you have to rally. What you do not want to do is give the receiver an offensive opportunity.
I recommend hitting a drive serve as the first serve. If you hit the
first serve short, you get a second serve. On the other hand if you hit
the drive serve long, it is very likely to
rebound off the back wall giving your opponent an offensive shot. You
have given up all the advantages of having the serve. Therefore, your
goal is to hit the first (drive) serve short. That way you have little
chance of hitting the ball long off the back wall and you have a decent
chance of getting the ace or a weak return. The most likely thing is
that you actually do hit the first serve short. See the discussion of drive serve targets below.
The server must stay within the five-foot wide service box. I recommend the two-step service motion which allows you to make the best use of this restricted space. I am going to assume that you are right handed. Lefties will have to make the necessary translation. Start by placing your left foot just touching (not over) the short line with the toes facing the side wall. Place your right foot behind your left foot also just touching the short line so that you are comfortably balanced. I like to turn my back (right) foot slightly so that the toes are on the short line, but facing diagonally toward the back wall so that I don't feel like I am walking a tightrope. Start the service motion by taking a small step with your back foot toward the front wall. At the same time raise your racquet arm to shoulder height (with the wrist cocked) and bounce the ball one to two feet from the front foot-fault line. Take a big step with your front (left) foot so that you step on, but not completely over, the foot fault line. Keep your toes pointed toward the right front corner. Your swing mechanics are the same as for any forehand. (See the Stroke Tutorial.) You should contact the ball near your front foot at the foot fault line. Keep your weight back, your head down, and follow through below shoulder level with the racquet facing down.
The problem with learning this technique is that, after you set your feet, everything happens at once. In aerobics class the service motion is called the grapevine. To practice it without a ball, put one foot behind the other, take the grapevine step while simultaneously raising both arms with the elbows bent. Think of it as a dance step. Doing this a few times should make your muscles familiar with the movement. Add a ball bounce with your left hand and, eventually, a forehand swing. Now you're doing the racquetball two-step.
The two-step delivery builds momentum toward the front wall and allows your upper body to rotate slightly toward the back wall (allowing more hip and shoulder rotation). The additional momentum and rotation combine to produce more power.
Part of the service motion is relocating to center court after the serve. Just after you hit the ball, you are at the 15 foot line, way too far forward. You have to relocate as quickly as possible to somewhere around the dotted line in center court. Simply push off the front foot and shuffle or run back to the dotted line, keeping eye on ball. Keeping your weight back is good form anyway, but for the serve it also allows you to relocate quicker to center court. Keeping your head down keeps the ball down. Following through below shoulder level keeps the swing flat (helping to keep the ball low), and following through with the face of the racquet down puts natural top spin on the ball, helping it to bounce twice.
Keeping your eye on the ball tells you what your opponent is up to in the back court so you can anticipate her shot or simply get out of the way. (If the ball comes off the side wall to the middle of the back court, you will have to move to one side or jump to avoid a penalty hinder. If you are not watching the ball, you will often be guilty of a hinder, be hit by the ball, or force your opponent into a shot she shouldn't have to take, all of which are bad.)
You should vary your serves by serving from different positions. There are essentially three positions in the service box. Assume that the receiver is in the middle of the back court. If you are practicing alone and the court has a standard three foot wide door in the middle of the back wall, the receiver's feet will generally line up with edges of the door. In the first location, right of center, you place your back foot in line with your opponent's right foot (right edge of the door). This gives you the best chance to momentarily obscure your opponents view of the ball on the down-the-line serve. In the center position, you put your back foot in line with your opponents left foot. This places you directly in front of the receiver. Finally, in the left of center position, you put your front foot in line with the receiver's left foot (left edge of the door). The cross-court serve to the backhand is momentarily obscured if you are in this position. In any of these positioins, be careful that the ball does not pass too close to your body for a screen serve. These positions put the mid line of your body eight feet from the left side wall (left position), the mid line of the court (center position), and eight feet from the right hand side of the court (right position).
Whenever you serve, you should take your time. Go through the same checklist every time: (1) Visualize your serve. (2) Check your receiver. (3) Place your feet properly at the short line. (4) Check your front wall target. (5) Find the point on the floor where you are going to bounce the ball. (6) Begin your service motion. (7) Hit the ball. (8) Shuffle back toward the dotted line while watching the ball.
Try to have the same service motion and foot work no matter which
serve you hit. Be consistent on the ball bounce and be sure to bounce
the ball so that you strike it around the foot fault line. This makes
it difficult for the receiver to anticipate the serve and generates the
most power.
So, to hit the ball directly into the back corner, we have to find the correct point on the front wall. Assume you are located in the center serving position and you want to hit a drive serve directly to the left side back corner, to a right handed receiver's backhand. (I am assuming you are right handed and are using the two-step service motion. Lefties will have to make the necessary translation.) With your feet in position, but before beginning the service motion, find the point on the front wall directly in front of the mid line of your body. Since you are in the center position, this point will correspond to the mid line of the front wall. To find this point you may want to follow the line of the flooring from the point directly below you to the front wall. Try to find a mark on the front wall corresponding to this point to focus on. (Plaster courts typically have a lot of marks around this point, for obvious reasons. If you are practicing on your home panel court, you can use some blue painter’s tape to mark the point. Just make sure you remove the tape when you are done.) This is the target. A ball that hits this point will rebound directly to the left rear corner.
Here
is a photo of my home court at William and Mary. (It is slated for
renovation
in a few months. The viewing area behind the glass side wall is
currently being
used as a store room.) Going from left to right on the bottom row
of
panels, there are two eight foot panels and one four foot panel. The
second row
starts at the left with a four foot panel then has two eight foot
panels. You
can use the cracks between the panels to estimate the distance from the
side
walls. I have superimposed some distance markers. The target
for the serve
to the backhand is the piece of blue painter's tape in the middle of
the wall
just above the 10 ft mark.

To verify this, do a phantom serve without a ball and put your racquet
down
where it will contact the ball at the foot fault line. The point at the
sweet
spot of the racquet (the widest part of the racquet) on the foot fault
line is
the “contact point” where the racquet contacts the ball. Standing
just behind this point, throw the ball underhand at the target. If you
hit the
target, the ball should rebound to the back corner. Now, still standing
at the
contact point, drop and hit the ball to the target. Again, the ball
should
rebound, at least approximately, to the back corner. Finally, starting
from the
center position on the short line and taking the full two-step service
motion,
hit some practice serves. Don’t worry about how high or how hard to hit
the serve,
just concentrate on the path of the ball. If you are hitting the front
wall close to
the target, most of the serves should wind up close to the back corner.
Experiment with serves just to the left and right of the target and see
what
happens.
You want the ball to take its first bounce just
over the short line, but not come flying off the back wall. This
depends on how hard you hit and the type of wall. The harder you hit
the ball, the lower on the front wall you should place the target. The faster the walls, the lower the target.
Plaster walls are generally faster than panel walls and usually require
a lower target. The horizontal pieces of painter's tape in the photo
above are 16 inches high, but anywhere between one and two feet will be
fine. When I play on plaster courts, I use a target between 6 inches
and 18 inches high. Experiment with serves that are higher and lower to
find the right level.
Hit some practice serves using the target and see how many are good.
Make adjustments as necessary. Even if you hit the target, the ball
will not always do the same thing because there are several other
variables in the equation. The ball drop is very important. If you are
not consistent in your ball drop, your contact point will vary, the
angle will change, and the ball will do something different every time.
Try to be consistent with your ball drop. The second thing that varies
is the angle of the face of the racquet as it contacts the ball. A
small change in the racquet face angle can make a big change in where
the ball goes. Finally, if you contact the ball with different parts of
the racquet face you will put spin on the ball. As a result, the angle
at which the ball comes off the front wall will change. Try to contact
the ball at or near the foot fault line. This maximizes power and
reduces the chances of hitting the ball with spin or with a variety of
racquet face angles. You will hit more powerful and more consistent
serves.
To vary the serves and keep the receiver off
balance, try serving from the right and left positions as well as the
center. To serve from the right position, put your rear foot in line
with your opponent’s right foot (or the right hand edge of the door).
Before beginning the service motion, locate the point on the front wall
directly in front of the mid line of your body, 16-18 inches up from
the floor. This is the target for the serve to the backhand. This point
should be approximately eight feet from the right hand side wall and
should correspond to a vertical line on a panel court on either the
first or second row. In the photo it is the mark just above the right
hand 8. The target for the serve to the forehand is half way between
the backhand target and the right hand side wall, approximately four
feet from the right side wall (with a vertical crack on either the
first or second row).
Z and jam serves
You should also mix in Z's and jams to keep the receiver from locking on to your drives. Also, some players just have trouble with these serves. The Z and jam are also good choices if your opponent is tired because tired players don’t want to move. Both these serves make your opponent move his feet. Obviously, if your opponent is getting good returns off your attempted aces, use more jams and Z’s.
The targets for the Z and jam serves will depend on how hard you hit and the type of wall. It will take some experimentation to find the best point. For a Z serve to the forehand from the right of center serving position, start with a point approximately four feet high and approximately two feet out from the left side wall. (The left hand Z in the photo above.) For a jam serve to the forehand from the right serving position start with a point four feet high and eight feet out from the side wall (the left hand J).
For the same serves to the backhand from the left of center position,
try points four feet up and two feet from the side
wall for the Z or eight feet from the side wall for the jam. (The Z and
J on the
right hand side of the photo.)
All these serves are easier to hit the closer the server is to the
opposite side wall. However, you should not start the service motion
from a point inside the drive serve zone because the receiver will know
that you cannot hit a down the line serve.
Low, hard drive Z’s and jams are tricky
because they
tend
to come off the side wall into the receiver's hitting zone. This
creates
an offensive opportunity. However, some players have difficulty
returning a
low drive Z or jam and occasionally you can catch a crack or get the
ball to bounce twice before hitting the side wall. To hit a low drive Z
or jam use targets 4 or 8 feet
from
the side
wall but only 2 to 4 feet off the floor. The one to two foot high
targets are
usually
too low to get the ball across the short line because the ball loses
momentum
when it hits the side wall.
Remember, these targets are approximate. They will depend on the court
surface, how hard you hit the ball, where you bounce the ball, if there
is any spin on the ball,
etc. Experiment and make
adjustments as necessary.
Crack serves go directly from the
front wall
to the side wall crack, and roll out. These are extremely low
percentage shots.
However, they do work every now and then. To hit a crack serve, move
your
target toward the side wall and hit the ball low on the front wall (one
foot high
on panels and six inches high on plaster). You run the risk of the ball
rebounding into the hitting zone of the receiver, generating an
offensive
opportunity, so be careful with crack serve attempts.
Vary your position (hit from all
three positions),
vary your serves (hit down the line drives and cross-court drives from
all
three positions; hit jam and Z serves from left and right of center),
vary the
speed and vary the height. Hit some inside out serves. Be deceptive. Be
able to
hit drives, Z’s and jams using the same service motion. If your
opponent
has an obvious weakness with respect to any of these serves, exploit it
until
he or she corrects it.
This is your last chance to put the ball in play. Your goal is now to generate a weak return while insuring that you do not hit a fault serve. Your best choice is a lob or half-lob.
The best location for hitting the lob is to the left of center, at the eight foot line, so that you strike the ball exactly in the center of the court. This makes it relatively easy to hit the lob to either side by angling the face of the racquet. The idea behind the lob is to make the receiver hit the ball at waist level or higher. There is no point to trying to deceive your opponent. The lob is slow enough that the receiver has plenty of time to react.
Here is a photo of the same front wall as above with some lob serve targets superimposed.
Assuming you are standing in the left of center position, the X's on the left hand side will correspond to the mid line of your body. Serves hit anywhere on this vertical line should rebound directly into the back corner. Lobs that hit the front wall 4 to 12 feet high will be half-lobs. Lobs hit higher than 12 feet will be standard lobs. Your goal is to get your lob to hit the floor in front of the dotted line, so it is difficult to cut off, and to take its second bounce at the crack between the floor and the back wall, so that it is difficult to hit an offensive return. What you do not want to do is to hit the back wall so that the ball rebounds toward the front wall. This gives your opponent too good a chance at an offensive shot. Hit the lob and half-lob with the racquet face open (about a thirty degree angle). Bounce the ball about chest high. Use your shoulders and arm to contact the ball. Keep your wrist stiff. Practice different lobs to get the right touch on the ball. Use the same left of center position for all your lobs (except the Z serve to the forehand) to reduce the number of variables.

Still standing in the left serving position, if your serve hits anywhere on the vertical line of N's on the left hand side, the ball will strike the left side wall behind the dotted line, generating a "nick lob" that rebounds into the receiver's body and, presumably, generates a weak or defensive return. My first racquetball camp instructor, Jack Newman, made a living on the tour hitting only nick lobs.
If you hit the front wall at the left hand J, you will generate a Jason Mannino "junk lob." This is a nick half-lob. The ball hits the floor around the dotted line, bounces up, contacts the side wall, and then rebounds into the receiver's body. It is a less predictable version of the nick lob. It can be hit at different levels and at different speeds. It is typically hit four to eight feet up just to the left of the mid line of your body. Jason Mannino, the number one player in the world for two years in a row, invented the junk lob and relies on it heavily. Watch the following short clip of Jason Mannino’s junk lob serve. It is very effective against players who are cutting off your serves.
Still standing in the left position, you can generate the same serves to the right hand side of the court (e.g., to a lefty's back hand). The right hand line of X's (six feet from the side wall, halfway between your body and the opposite side wall) will generate lobs that rebound directly to the cornerl. The right hand column of N's will yield nick lobs and the right hand J will generate junk lobs to the right side.
Lob
and half-lob Z serves
Hit the lob and half-lob Z's to the forehand (leftie's backhand)
from the right of center position. The target for the half-lob Z is
6-12 feet up and 2 feet from the side wall (between the bottom two left
hand Z's in the photo above). This serve can be hit at a variety of
speeds. At higher speeds the ball bounce directly out from the side
wall. If hit well, the ball should hit the side wall deep and then
almost roll along the back wall. At slower speeds the ball will hit the
side wall and bounce diagonally toward the back wall jamming the
receiver.
The target for the lob Z is 2 feet from the side wall and 12 feet
up, or higher. (The top left hand Z in the photo.) The goal is to get
the ball to bounce near the dotted line, so it is hard to cut off,
contact the side wall high, and bounce diagonally to the back wall
where it dies.
The lob Z and half-lob Z to the
backhand is hit from the left position. The target for the half-lob Z
is a point 2 feet from the right side wall and 6-12 feet high (bottom
two right hand Z's in the photo). The target for the lob Z is two feet
from the right side wall and 12 feet up or higher. (Top right hand Z in
the photo.) I find
this serve is easier to hit using the backhand. Remember to
keep the racquet
face open.
Don't forget, these targets are approximate. Make adjustments as
necessary.
You should choose among lob serves depending in part on the receiver's actions. If the receiver is not attacking the serve, you should hit the standard lob or half-lob. The point of these serves is to get the ball deep in the back corner so that the receiver has to return the ball to the front wall from 39 feet while simultaneously dealing with two walls. If he or she is aggressively attacking your lobs (cutting them off and hitting offensive shots on the short hop or mid-hop), you should (1) adjust your delivery so that the ball bounces well in front of the dotted line or (2) hit the nick lob, the junk lob, or the half-lob Z so that the ball deflects off the side wall into the receiver at least waist high. The idea is to give the receiver a ball that is traveling slowly, that looks like a setup, but is really too high to shoot properly.
After you hit the serve, you should hustle back and try to relocate to good center court position around the dotted line. Do not dawdle in the service box. Remember, if you are in the service box, you are in front of the dotted line and extremely vulnerable to a passing shot. Get back as quickly as possible. Because the drive serve goes so fast, you will probably not be able to get past the dotted line before the serve is returned, but you should try to get to the dotted line. On a lob serve, you should be easily able to get to good center court position. Also, remember to keep eye on ball. Don't watch the front wall when the ball is behind you.
Players do not practice their
serves enough.
Practice your serves more, play less, play better.
