This book, by one of the first and foremost authorities on contract bridge, is regarded as the classic exposition of playing strategy. Practically all variations of play, both in attack and in defense, are explained and illustrated in it.
It is a very nice and classic book for bridge players, almost like a must-read textbook if you are new to bridge. The author explained the concept clearly, especially for the elementary concepts with specific examples that were easy enough to understand the main gist. However, for the advanced part of the book, the author mainly introduced the skills and explained how an endplay/squeeze works but did not mention the actual application. It would be good for beginner to intermediate players, advanced players may also find it useful if they are confused with the fundamental card play concepts.
