The Viking Club has been created with the idea of reaching the best contract; in fact the higher that contract is, the better. An important starting point in Viking is a straightforward strong-club base like Precision. If you want to learn this system, you should know the principles of Precision Club in advance, as well as being familiar with the principles of natural bidding. A good book for this is "Precision in the 90's". This book which was published in 2000, contains 256 pages.
