I've heard that it is a good idea to test the net person, especially if you get a sense during the warm-up that their volleys are suspect. I cannot bring myself to do this. If they stand too deep, near the service line, then I suppose it isn't too hard to hit a topspin shot that dips. But what do you do when they hug the net, as most weak volleyers tend to do? Is there a best way to hit this shot? Won't they just block it back for a winner? Should I tell my partner ahead of time that I am planning on doing this, or should I do it in response to a weak serve? Does it work best in the middle of a point or off the service return? Should you aim at a particular spot, or do you just put your head down and swing hard? I find soft balls tougher to volley than hard-hit balls, so should I take off some pace?
