Serving Patterns

During a match,  Is it really important to execute a serve randomly or in a definite pattern or manner? 

Name the serve which is ideal for both the state level as well as national level player.

Hi Aryaman,

I think each point is different.  You need to watch you opponent to see what they are getting prepared for.  You also need to think about what type of return they made from the previous serve you did.  This is all important factors as to the serve you are going to do next.

All serves are good for all levels of play.  As the level gets higher, the serves also improve.
