“We are given what Marin feels are the very best ways for Black to play, while refusing to hide the good stuff’ for himself. I have never seen an active professional grandmaster do this before… Clear and incredibly useful explanations literally fill every page.”

IM Jeremy Silman

“The depth and thoroughness of the introductory comments is absolutely astounding. I now know that my knowledge of the deeper strategies behind these lines was very superficial and left much to be desired on several levels. This book is simply phenomenal and a must buy for anyone playing either side of the Ruy Lopez. This is easily one of the very finest opening books of the year.”

Carsten Hansen, ChessCafe

“His own analyses are everywhere, which in Marin’s case doesn’t just mean a novelty here or there but also involves some well-thought-out arguments. His explanations are world class… I would recommend Marin’s work for those wanting a lesson in strategic thinking along with strong GM-insight.”
