Conventional Bidding Explained
Freddie North

Swedish Expert Methods-Volume Four. In this volume, Mats Nilsland reverses the definition of the double, instead saying "Double is for take-out unless defined otherwise." That opens many new roads to travel, at the same time giving your side lots of opportunities to sort out various hand types and strengths. There's no doubt about it: the future of bridge belongs to the take-out doubles. This book which was published in 1998, contains 56 pages.
