Positional Gruenfeld Repertoire - Part 3

The third and final part of GM Mihail Marin's "Positional Gruenfeld Repertoire" is here! The trilogy is completed with an examination of popular systems that involve developing the white bishop to g5 and f4, as well as the Fianchetto system (with g3). In the final chapters, GM Marin also covers less popular alternatives, such as the interesting 3.f3!?, as well as various 4th and 6th move alternatives for white. His theoretical recommendations, as usual, have the benefit of being fundamentally strategically sound, while somewhat less explored. This is a good combination in today's computer-driven chess era, especially for those who want to avoid long and sharp theoretical battles.

The Sicilian Kan - Repertoire for Black

The Paulsen Sicilian, also known as Kan variation is one of the most practical options for Black against 1.e4. A perfect mix between the Scheveningen – Taimanov – Hedgehog schemes that allows you to play a fighting game without many forced lines. Many strong grandmasters have employed it regularly and achieved great success with it, Lajos Portisch, Ilya Smirin, Vadim Milov just to name a few. Not just that, champions like Carlsen and Kramnik have played it successfully as well. The main incentive to play the Sicilian Kan is to take your opponents into a battle where talent and creativity overweight memory.

Positional Gruenfeld Repertoire - Part 2

In this survey, GM Marin deals with some of the most critical White's responses to the Grunfeld Defence such as the classical main line in the Exchange System and the so-called Russian System. True to his creative approach to the opening, in a number of well-known theoretical lines, the author suggests original continuations which are not extensively tested in practice. Of course, every suggestion is based on solid positional grounds.

Positional Gruenfeld Repertoire - Part 1

Nowadays, Gruenfeld Defence is one of the most topical and complicated openings. Practically, every top-player has the Gruenfeld in his opening repertoire. Still, the complexity and the enormous amount of theory make a number of players reluctant to play this opening. This is the reason why we decided to start another ambitious project - complete Gruenfeld repertoire in three parts prepared by GM Mihail Marin. Being aware of the fact that it is difficult to study a new opening without knowing the typical middlegame positions which could be reached, we have decided that this database should start with some pawn structures that every Gruenfeld player should know. The coverage of the structures is based on 4 articles that GM Marin wrote for Modern Chess Magazine. After studying the arising positions from a structural point of view, the reader will better understand the theoretical part of the database.

Classical Anti - Scotch Repertoire

Given the fact that nowadays White experiences major difficulties to obtain an advantage in Ruy Lopez, he started looking for decent alternatives. That is why the so-called Scotch Opening became highly popular even at top level. In the recent years, modern practice showed that the Scotch offers a variety of interesting and unexplored positions. That is the reason why among it's supporters we could find the names of creative top grandmasters like Maxime Vachier-Lagrave, Ian Nepomniatchi, Alexader Morozevich and of course the great Garry Kasparov. The current data is designed to provide the reader with a solid Anti-Scotch repertoire which can be used at any level.

The Steinitz Defense Deferred

The Steinitz Defence Deferred is an interesting and still relatively unexplored system against the Ruy Lopez (3.Bb5). Apparently passive, yet extremely solid and quite flexible, it has survived the test of time since the late 19th century. Chess greats like Janowski, Schlechter, Capablanca, Alekhine, Keres, Smyslov, etc. The aim of this opening survey is to provide you with an easily understandable and concrete Steinitz Defence Deferred (in further text SDD) opening repertoire against the Ruy Lopez. SDD is a relatively rare occurence on the top level, but this can be a blessing in disguise for a club or a casual tournament player. Many white players dismiss such opening variations as second-rate and pay less attention to them than to Breyers and Marshalls of the world, on which they are ready to spend countless hours of analysis. If your knowledge of SDD is solid and deep, while your opponent's is superficial and coupled with "today I play against that off-beat Ruy Lopez line" approach, guess who has the upper hand?

In our computer-driven time, the level of preparation is drastically increasing. Sometimes, even top players face difficulties to outplay regular 2300+ rated players.

If you need an opening which is dynamic, strategically sound and offers plenty of possibilities to outplay your opponent, the Modern Benoni is your bread and butter. In his latest database for Modern Chess, one of the best Benoni experts in the world, GM Mihail Marin provides you with a complete Benoni repertoire.

As always, Marin divides his database into three sections - Pawn Structures, Theoretical Section, and Test Section.

Positional Repertoire against the French

French Defence is a tough nut to crack. This opening has a reputation for being a very good counter-attacking weapon. It was used with success by almost all the great players at the past and nowadays. Since the arising middlegames are extremely complex, usually, all three results are possible. Above-mentioned considerations explain why the choice of weapon against the French Defence is so important when we play 1.e4. In the current database, IM Renier Castellanos suggests a positional repertoire against the French which is based on the so-called Tarrasch Variation.

Classical Repertoire Against Bogo - Indian Defence

The Bogo - Indian Defence is one of the most topical opening after 1.d4. Every 1.d4 player should be very well prepared against it. White has several ways to meеt 3...Bb4+, but 4.Bd2 - is the most natural option, which would be the topic of the current survey. White is not aiming to get the pair of bishops but is continuing the normal development, counting on his space advantage in the center. What I like about the line 4.Bd2 is that White's play is natural and positionally sound. It's true that often White's advantage will be marginal. However, I strongly believe that when your opening is based on a good positional ground, it's easier, at least from a practical point of view, to handle the position in the middle game as well
