SOS allows amateurs to play the opening like a pro without spending nearly all their free time studying stuffy theory. Readers of this series can ignore large areas of the ever expanding chess opening theory, because they can concentrate on these very early deviations (usually before move six!) from the regular lines in main stream openings. Ideal for club players with a basic knowledge of openings, who have not enough time to keep up with the latest fashions. A refreshing change, is what GM Nigel Short wrote about SOS in The Daily Telegraph.
