This is the sequel to Marin's successful "Beating the Open Games", in which the author dealt with all white's options up to 3.Bb5. Now Marin provides all the answers for Black after 4.Ba4 in great depth. Some quotes from the foreword will give you an idea of the concept and contents of this remarkable opening book:

--"...I have put strong emphasis on the notion of development, which offers the most reliable guidelines in any open games. It is easier and more constructive to follow just a few general recommendations about development than remember a large mess of variations."

-- about the structure of his book: "The introductory part deals with the general aspects as well as with the historical evolution of the variation. The theoretical section contains detailed analysis, which aims to be one or two steps ahead of the current stage of theory." (!!)

-- again, about the structure, that has the book start with the main variation and finish with sidelines, contrary to other opening books: "The main line is by far the most complex from a strategic point of view. Once its basics have been assimilated, the other variations become easier to understand."

Marin takes TWO variations in the Chigorin variation as his main variations. As he explains, "by choosing two systems based on opposite approaches, my intention is to offer a wider perspective on the Chigorin variation as a whole".

First he deals extensively with what he baptizes the 'Rubinstein Variation' of the Chigorin variation: 1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 d6 8.c3 0-0 9.h3 Na5 10.Bc2 c5 11.d4 Qc7 12.Nbd2 Nc6. In the next chapter the Petrosian variation (12...Bd7) is covered in great detail.

The remaining chapters deal with earlier deviations, from black's point of view, going back all the way to 5.d4 and 5.Nc3.

This depth of chess expertise has rarely been published for a mass audience before, as grandmasters usually prefer to keep their secrets. The complexity of the material could have been daunting, but Marin is also a master of explaining profound ideas to a wide audience.

If you wish to know more about the Chigorin variation, or about the Closed defence of the Spanish, or about the Spanish Opening in general, you won't find anything better than this. A magnificent effort.
