Summary: <h4>Question 1 - 0:28</h4> <p>Hi Alois, I've noticed that the quality of the training some how depends on the mood and the concentration. The same strokes I perform differently and miss more with the higher concentration on the ball. What is an object and level of concentration? Olena</p> <h4>Question 2 - 3:14</h4> <p>I play at a local club and have received comments that I have a good serve. However, I have noticed that almost all of my backspin serves (Pendulum) have sidespin as well. Is this taking away from the effectiveness of the backspin? Adam</p> <h4>Question 3 - 5:32</h4> <p>While playing with my opponent when I tossed the ball for a serve my opponent asked me to stop as he wasn't ready then after a pause of 4 to 5 seconds I served again and again the same thing happened. Is this legal? Rutvik Thakkar</p> <h4>Question 4 - 8:31</h4> <p>Hi, sometimes I see professional players immediately smash the ball when returning a serve, I was wondering in what circumstances could and should you do this. Thanks! Alan C</p> <h4>PingSkillers Question - 11:12</h4> <p>Who is the best player you have ever seen?</p>
