If you're on the left side of the court and the opponent you're facing is right-handed, move to the left and play more of the line, your partner should also move to the left towards the middle to cover the ground. 

Why? Because that right-handed opponent most likely will shoot straight or towards the line rather than across the entire court. Then immediately return to home position.

1. Put the player (usually the tallest)with the longest forehand reach on the left and keep them there.

2. Strongest powerful forehand on the left for that put away shot. 

3. Righty on the left, Lefty on the right, puts both forehands in the middle. The only danger is you really have to call which one takes it a lot more since they both have the advantage. 

4. Highlight a strength/Minimize a weakness: Put the player with the weakest backhand on the right because it can be protected by the left's forehand. 

5. Put another player in front of another player: if a player is constantly getting beaten by a speed up, switch sides.

6. 0-7 score, just change it up to give them a different look, to try something different.

There's only one type of short ball you actually want to drive. The rest, 100% of the time you want to drop. That is if the ball is short and high and by high I mean that it is at least at net level. 

That way you can at least hit the ball horizontally, because as soon as you speed up a ball from a low position, you're hitting the ball up to your opponent. So simply all that they have to do is put the ball down and 9 times out of 10, this ends the rally instantly. 

So if the ball is short and it's not at net height or above please do not drive that. Instead drop the ball, move up to the net and then look for a greater opportunity to hit downward on the ball. 

So remember the saying “if it is short and high let it fly and if it is short and low, keep it slow.”
