Hey, I watched a video on youtube and the guy said, it's better to do a low serve at the middle of the half-court when you serve. So instead of focusing on the "T", you should aim for the middle, between the "T" and the sideline. But he didn't explain. I've always thought it was better to aim for the "T". Also, he said, the best way to return a low serve was to aim for the rear forehand of the opponent but didn't tell why... I've always thought it was better to aim for the backhand on the rearcourt. If you have a few explanations I'd be thankful.
