An SOS deviates very early from the regular lines in a mainstream opening, (usually even before move six) and brings you a wide variety of unusual opening ideas. They may seem outrageous at first sight, but have proven to be perfectly playable.That is why it is so easy to actually bring the variation on the board. You will baffle your opponent without having studied large quantities of stuffy theory.
Carsten Hansen, ChessCafe: ‘The variations can be exceedingly difficult if you are not prepared.’
IM Watson, The Week In Chess: ‘The most entertaining of books about openings that I know of (…) I recommend SOS because it is so much fun, to be sure, but also for its practical utility.
Joe Petrolito, Australian Chess: ‘These suggestions are very attractive to club players.’
Chess Today:> ‘No matter what you play, you will find something exciting here.”
