Once you get better at this strategy you can play slightly to his weaker side. Most players do not own any shot, one that they can hit consistently from anywhere on the court to any position, so worrying about a strategy complicates their game. They must deal with stroke production and not having the shot to fulfill the strategy. It is better for the beginner to just hit the ball correctly. A basic law in the jungle is that the advanced player will attack the net at every opportunity and the intermediate will wait for the first short ball before going in.
Anticipation is a key element in the development of an advanced player.
An intermediate will often hit and back up or hesitate too long when getting his opponent in trouble or sensing when a ball will be short. The average player is average because he seldom hits the ball deep. In fact against most players the odds are that the next ball or every other ball will be short so you should anticipate this probability and be inside the baseline expecting a short ball. Good tennis is a game of opportunities, it is a game of closing out a point and not letting your opponent keep playing. This means you must fight to get to the net.
