Another how-to-improve-if-you're-a-hacker tennis book, including strategy and stroke tips-the slice serve pays off because it's tough on people with bad backs; a good chip shot works because it makes the net-rushing opponent play a low volley, and effectively disrupts his attack--as well as a rundown (brief, but interesting for armchair matchwatchers) on how to play each of the top pros on the circuit today. An o.k. but not spectacular instructional packet by one of tennis' Grand Old Men.
