Practice Serve

Try new serve technics. The ball getting spinnier but some balls are missed. I need more practice to make it better.
My forehand is very dominant compared to backhand. Now even receiving serve I use forehand for next forehand stroke. I barely used my backhand this time. That was not good practice to improving my weakness on backhand stroke. I lost many points on this side. However my overall game was getting better. Should I stress on my strength or my weakness?

vs Hamid (3-4)
- stay back off table
- return serve to my left hard to take, only several block land on table . I need to do more fast backhand stroke to overcome this.

vs Zuri(3-2)
- another upset. I lost first 2 games but came back for winner.
- strength; fast serve to body and drive to his left.
-weak: Struggle to take his loops to my left(backhand) .

vs Mie Sulong(4-0)
- loop his serve
- stay calm
- he was too 'gopoh'
