What people say about SOS

"For throwing your opponent off balance, it is hard to beat this series."
Bob Long, Chessco

“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

“A refreshing book, full of rare, uncommon but sound ideas that can spice up the opening repertoire of any tournament player.”
Lubosh Kavalek in The Washington Post

“These suggestions are very attractive to club players.”
Joe Petrolito in Australian Chess Magazine

“New moves as early as move five are always attractive. Every line mentioned has a tactical and/or strategic justification and can be used with confidence.”
Jeremy Silman, author of How to reasses your chess

“Tricky opening ideas, not much to learn, surprise value and lots of fun!”
Glenn Flear in Yearbook 71

“Bosch's analysis is generally strong (he is an IM), a quality which contrasts with the poor work often done by enthusiastic advocates of strange and/or irregular moves. I think that readers on most levels, say, from intermediate player to master, will get something of value out of this book”
John Watson at TWIC Book Reviews

“Boy, are some of these ideas surprising! No matter what you play, you will find something new and exciting here.”
ChessToday

“A refreshing change from the usual dreary technical works.”
Nigel Short in The Daily Telegraph
