<human>:  I know how to play tennis but I am having trouble making backhand shots. How can I improve my technique?
<bot>: The key to improving backhand technique is to make sure you have the correct grip. Start by holding the racket with your dominant hand, wrapping your index and middle fingers around the handle. Your thumb should be placed on the side away from you, and your other two fingers should lie on the other side of the handle. Next, focus on the angle of your racket. The more open racket angle will cause a greater margin for error, so focus on a more closed angle as you swing. Finally, practice maintaining this grip and angle as you hit the ball, and repeat as often as possible!
