When we are in command of the rally it is desirable to keep pressure on the opponent by attacking.  Why?

• trying to force an error
• set up an opportunity to hit a winner
• make the opponent expend more energy
• break the opponent's spirit

Keep the opponent on the move:

• Hard drives
• Tight drives or lobs
• Volley
• Volley Boast
• Nicks/Kills

Recover back into the rally by:

• moving the opponent from the middle of the court.
• getting back to the T
• controlling the speed of the rally

A great saying is "only hit the ball as hard as you can run" - this is to allow sufficient time to get back into position. These are the main shots to enable this to happen:

• Tight length
• Lob down the line tight
• Cross court lob

These are not meant to be winning shots, but great positional shots to set up an opportunity.
