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.

Complete Repertoire against King's Indian Defense

How to play against the King's Indian is a question that every 1.d4 player faces. The world-renowned theoretician and author GM Boris Avrukh provides you with an answer. His antidote is based on the set-up with 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.Be2 d6 6.Be3. This is a very interesting move order that has not been particularly popular until the Russian Champion Grandmaster Alexander Riazantsev has started to employ it actively. In his new opening database for Modern Chess, Avrukh presents some of the ideas he found while working as the second to former World Champion Vladimir Kramnik.

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.

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.

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.

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.

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?

Complete Repertoire against the Benko Gambit

In his first opening database, GM Evgeny Postny provides us with a complete repertoire against the Benko Gambit. Instead of taking the pawn, White starts fighting for the initiative by playing 4.Qc2. In his analysis, GM Postny proves that even if Black plays correctly, White manages to retain a small edge in a risk-free position. This is certainly the scenario Benko players are afraid of.
