The first essential of doubles play is to PUT the ball in play. A
double fault is bad in singles, but it is inexcusable in doubles.
The return of service should be certain. After that it should be
low and to the server coming in. Do not strive for clean aces in
doubles until you have the opening. Remember that to pass two men
is a difficult task.

Always attack in doubles. The net is the only place in the court
to play the doubles game, and you should always strive to attain
the net position. There are two formations for the receiving
team: one is the Australian formation with the receiver's partner
standing in to volley the server's return volley; the other is
the English and American style with both men back, thus giving
the net attack to the server. This is safer, but less likely to
produce a winning result unless the team is a wonderful lobbing
combination. Lobbing is a sound defence in doubles, and is used
to open the court.

I believe in always trying for the kill when you see a real
opening. "Poach" (go for a shot which is not really on your side
of the court) whenever you see a chance to score. Never poach
unless you go for the kill. It is a win or nothing shot since it
opens your whole court. If you are missing badly do not poach, as
it is very disconcerting to your partner.

The question of covering a doubles court should not be a serious
one. With all men striving to attain the net all the time every
shot should be built up with that idea. Volley and smash whenever
possible, and only retreat when absolutely necessary.
