Answer: Hi Ahijit, badminton deception is a very complicated skill to master. I’ll just mention briefly here on how to play deception.
There are many different ways where you can deceive your opponents in badminton.
The common one is where you hold the shuttle at its position for a while and hit it when it lands low.
In order to do this, you must be able to reach the shuttle as early as possible, let your racket follow the shuttle for awhile, then flick your racket towards the direction you want the shuttle to land.
In order to play deception you MUST have extremely good basics. This skill involves a lot of precision and creativity.
Usually if you have strong and solid badminton basics, you will naturally develop your own ways to deceive your opponents.
Therefore the key here is to master and polish your basics.
When your mind can passively instruct your body to perform good and quality basic shots, your mind will then be able to actively think of creative ways for you to play deception during your badminton game.
