The volley is the most demanding shot in tennis.
It is the most technically difficult, requires players to be exceptionally athletic and calls for lightning reactions.
By coming forwards in the court you are putting huge pressure on your opponent and also opening up all the angles - making winners much easier.
It can be a gamble though.
You have less time to cover the width of the court.
So if your opponent gets in a good shot only exceptional movement and reactions will get you out of trouble.
The ready position is crucial.
You do not have time to waste by bringing your racquet from the incorrect position.
Alter the ready position slightly from the way you would prepare for groundstrokes by bringing the racquet head slightly higher.
Move the elbows forward so they're just in front of the body.
As you see the ball coming move your head and hands towards the ball.
This should bring the racquet head out into position in front of you.
If you do this correctly you should feel your upper body go to the ball and your feet following.
In emergencies this can turn into a controlled lunge or even a dive.
Do not swing the racquet at the ball, the shot should be short and punchy and take place almost entirely out in front of you.
Use your wrist and forearm to bring the racquet head down on the ball in a short, sharp action.
Make sure that the racquet face is slightly open.
The downward action and the open racquet face should send the ball shooting through the court with a little bit of backspin.
This will keep the ball low off the bounce making it more difficult for your opponent to pass you.
Follow through in the direction you want to send the ball.
Then get back into the centre of the court as quick as you can ready for the next shot.
Don't worry if you get passed or lobbed a few times.
Coming to the net is a very aggressive but slightly risky play.
The players that excel at it are exceptionally athletic but also have an attacking gambler's mind set.
