Petrosian System - Complete Repertoire against Queen's Indian Defence

In this database, GM Boris Avrukh is dealing with one of the most solid and respected weapons against Queen's Indian Defence - Petrosian System. The starting position of the variation arises after 1.d4 Nf6 2.c4 e6 3.Nf3 b6 4.a3 In different time periods, Petrosian Variation was employed by many top players. For instance, nowadays, this is the way in which Mamedyarov meets the Queen's Indian Defence. Theoretically speaking, like in every decent opening, Black should be able to hold the balance. From a practical perspective, however, White's play is easier. In many positions, Black struggles to obtain counterplay. In his current work, Avrukh presents the modern way of playing the Petrosian System. He provides a number of decent novelties, as well as powerful positional concepts. Also, he explains all the thematic ideas in the variation. The database consists of 11 theoretical chapters and 20 test positions.

Complete Repertoire against Veresov, Trompowsky, and London

The Trompovsky Attack and especially the London System have become quite popular openings in recent years. This should not come as a surprise. In our computer age, when most of the forced lines lead to a drawn outcome, top chess players began to look for ways to play for a win in less studied and forced openings. Veresov Attack is also an interesting try to reach fresh and unexplored positions. It can be quite dangerous if you are not prepared. GM Pavel Eljanov proposes a universal way to deal with these openings. In his concept, the main idea is to fight for the center as well as to limit the activity of White's bishops through exchanges or the threat of exchanges (and we know that the threat is often stronger than its execution). The repertoire is based on solid positional grounds and the author is trying to offer similar setups against all three openings.

Since a long period of time, the so-called Rauzer-Richter Variation is been considered as one of the most reliable Sicilian weapons. A simple check in the database is enough to see that over the years this line has been employed by the World's best players.

1.d4 Nf6 2.c4 e6 3.Nf3 d5 - Ragozin and Queen's Gambit with 4...a6 for Black

In the second installment of 'Repertoire for Black against 1.d4', GM Kuljasevic suggests an opening repertoire against 3.Nf3 based on the Ragozin Defense (4...Bb4) and Modern Queen's Gambit (4...a6). Similarly to the Repertoire against the Catalan, the idea is to have one equalizing opening system that you would be comfortable playing against strong opponents, as well as one sharp system that you would use to imbalance the game, get your opponent out of his comfort zone, or just get a playable game without much opening theory, hoping to outplay him in the long run. In this database, the Ragozin Defense will have the role of a solid equalizing weapon, while the Modern Queen's Gambit will be the sharp one.

Complete Najdorf Repertoire for Black - Part 1

The Najdorf is the most popular Sicilian played in tournaments, and our author IM Renato Quintiliano considers it the most reliable option in the Sicilian universe. It promises an active game for Black and real chances of playing for a win. The main practical problem for Black, however, is that White has a really wide range of options to face the Najdorf. White can even avoid an open and sharp battle for the initiative and instead go for more solid and positional lines, which can prove a problem for aggressive Black players. It means that if you want to develop a deep knowledge about the Sicilian Najdorf, in order to use this opening as a weapon in your repertoire, it is necessary to not only be aware of long and sharp theoretical lines, but also of positional ideas, typical maneuvres and structures, developing a good strategic understanding about them. These positional lines will be the subject of our first (of three) databases dedicated to the Sicilian Najdorf.
