I used to use a 2 handed backhand for a year. Whatever I did, I could not hit it smoothly, or find the sweet spot on the backhand with two balls, so it would just lead to errors. Now, I use a 1 handed backhand and 50% of the time, the ball goes into the net with the stroke. I have no idea what is wrong but my coach says that I use my wrist too much. Does anyone have any drills to stop the wrist from killing my backhand game? Also, can someone lead me to good chip shot instruction sites?
