Stick to one plan or different styles

Should I have a certain plan like : push and then play on the opponent body and then play a wide forehand OR I can play randomly and change from attacking to defending at any time and try chopping then attacking and doing different flicks 

Hi Abdulrahman,

Variation is one of the things that opponents will find difficult to deal with.

However, if you have something that you opponent is not dealing with then you can stay with that strategy till they start to adjust to it.
