Defence is the hardest part of card play according to Patrick O.Connor. His book, is titled Demystifying Defense. When dummy tables their cards the declarer can see all the assets of their side and can count potential winners and losers. However, a defender can see dummy and only half of their side's assets. Also, during play defenders must combine effectively to execute a successful defence.
Starting with chapters on Opening Leads and Third-Hand Play and Second-Hand Play with a quiz at the end. Next is Defensive Signals. The main part of the book contains 40 'over the shoulder' deals where the author invites you to defend with him, trick by trick, with questions and answers. Oh and there is always a Post Mortem! Deals become progressively more difficult to assist all levels of players.
