After looking at numerous books on golf technique, this is probably the best available at the price.
There are numerous colour photo's to illustrate exactly what the author is describing. Everything from the basic stance and grip to advanced subjects such as pushing/pulling the ball and altering the shape of your shot to avoid obstacles.
Each chapter in the book covers a different area of the game e.g. iron shots, tee shots, etc. At the start of each chapter there is an evaluation test that helps to determine your level of play. Once this has been established you have a choice of reading the beginner, intermediate or advanced sections of that particular chapter. There are plenty of practise exercises available to improve your game play and tips on how to correct faults.
As a newcomer to the game I have found this book invaluable.
