But facing the facts of life and recognizing that it is not your fault you are going to have to accommodate this failing and improve your defense. It's a hard part of the game; even in international competitions the standard of defensive play is to put it kindly modest. Yes you will get plenty of reports of brilliancies involving spectacular switches deceptions unblocks and discards of honours. But for every one of those there are countless others in which the display would disgrace any beginners' class.
I am going to assume that you are a regular club or tournament player who knows the basics of defense but who comes unstuck when it comes to situations where you have to work the hand out in detail. This book will help you to improve dramatically in this area.
