What people say about SOS:

“SOS is a sparkling star in the grey sky of theory.”
HEINZ BRUNTHALER IN ROCHADE EUROPA

“We are all trying to outsmart our opponents
in the opening, and this can be achieved with
very little effort using the numerous curveballs
that are included. The variations can be
exceedingly difficult if you are not prepared.”
CARSTEN HANSEN AT CHESSCAFE

“No matter what you play,
you will find something exciting here.”
