Since C.C. Wei brought out the original book on the Precision Club system, his ideas have influenced many of the world's great bridge players. In the last twenty-five years, however, there have been no significant publications detailing the advances in expert thinking on Precision. This book combines a detailed outline of basic precision with a survey of how the world's top players have modified and improved Precision to make it an even more forceful tool. Precision in the 90s should prove an invaluable asset to both beginner and expert in the Precision Club. It will give the beginner an idea of how Precision works and stimulate the expert to find new ideas and approaches.
