There is no need to try to get an ace on a serve. As you move up in levels, top players can return any serve. When you add the extra power and spin, you increase your probability of error. And the worst thing you can do is lose a point on your own serve (the only time you have complete control)
It is never a good idea to throw a point away. When serving you have the ball in your hand, controlling the start of the point. When receiving the serve…you know it is coming to you! Therefore, since you only get (1) serve and (1) return of serve, you should get it in. The reason to keep the serve and return of serve deep is to make it harder for your opponents to get to the ‘kitchen’. Only at the top national levels, can players make (and practice) a fast or tricky serve that will benefit them. Even at those levels, it’s very difficult because their opponents are so good, no matter the serve, they will be able to return it easily. In all levels, the team/person that keeps the ball in play the most, will win.
