Recently I had one of those moments where I caught the suckers off guard. Its a great idea to hit a completely unpredictable low percentage shot, just to make them think. It was doubles, and I had been lobbed. When lobbed 99% of the time I lob back. My opponents began to drift forward cautiously so they could come to the net, but still be in position to hit an easy overhead if I did not lob perfectly. I had looked over my shoulder to see them on my way back. So I.... turned and ripped a huge forehand BOOM right down the middle of the court between them. They just watched it go past, then looked at each other in bewilderment. "I guess you didnt see that coming?" It was a social match, so a little trash talk livens the proceedings.
