Moscow Variation against the Sicilian - Complete Repertoire against 2...d6

Nowadays the Moscow variation is extremely popular, and one of the reasons is the current World Champion Magnus Carlsen. His approach to the chess has changed the way of thinking for many - not to strive for advantage in the opening, but get an easy play with a logical development of the pieces. Don't be mistaken though - Magnus Carlsen may play off-beat variations but he does know them really well. Right now pretty much all of the top level players who choose 1.e4 play a decent amount of the Moscow variation as well.

Reversed Sicilian - Avrukh's Antidote to 1.c4 (Part 2)

In the second part of his repertoire against 1.c4, GM Boris Avrukh deals with the systems based on 2.g3 and 2.Nc3 Nf6 3.g3 Against these two move orders, we cannot reach the Reversed Dragon with Bc5 which was discussed in Part 1. Of course, you can still play Reversed Dragon by employing the main line with Nb6. Nevertheless, Boris doesn't like the fact that White has too many possible options. As always, Avrukh chooses a very aggressive repertoire. Systems after 1.c4 e5 2.g3 c6 and 1.c4 e5 2.Nc3 Nf6 3.g3 Bb4 are positionally unbalanced and very complex. Avrukh did a fantastic job by providing the readers with a variety of novelties and sometimes even with new concepts of play.

Reversed Sicilian - Avrukh's Antidote to 1.c4 (Part 1)

Every chess player has faced the dilemma of how to meet the English opening. 1.c4 is objectively a weaker move than 1.e4 or 1.d4, but it is by far the trickiest option for White on move 1. With so many transpositions, different setups and move orders, White has plenty of options to turn the game into the desired setup. That’s why we are pleased to announce this database in which one of the top theoreticians in the world – GM Boris Avrukh, provides you with a complete, aggressive repertoire against 1.c4. Black has many choices after 1.c4, but the Reversed Sicilian (1…e5) is by far the most principled move. Hence it is no surprise that GM Avrukh decided to base his repertoire on it.

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.
