These four databases provide you with a lifetime repertoire against the Sicilian Defence. All the databases are divided into three parts - Pawn Structures, Theory, and Test Section.
This package includes 5 opening databases which provide you with a complete solution to the King's Indian Defence. Each database includes a theoretical section and interactive tests. The bases Play the Makagonov against King's Indian Defence by GM Mihail Marin and Complete Repertoire for White after 1.d4 Nf6 2.c4 g6 3.g3 by Roiz also include typical pawn structures.
These two databases provide extremely practical lifetime repertoire for Black. Since the arising positions are not forced, the understanding of the arising pawn structures is more important than the knowledge of the theory. On the other hand, the flexibility of Black's setup makes possible to play for a win.
The English Opening has always been one of White's most fundamental choices. You will hardly find a top-level player who does not have this opening in his repertoire. Nowadays, in our computer-driven era, English Opening is getting even more popular. The reason is that it is by no means simple for the opponent to prepare against 1.c4. Since the pawn structure is very flexible, we have a wide range of options on every move. Therefore, in most of the lines, general understanding tends to be more important than knowledge of concrete lines.
In these 2 databases, GM Michael Roiz provides a complete repertoire for White after 1.d4 Nf6 2.c4 g6 3.g3. The suggested repertoire is highly practical. The author usually goes for relatively untested and underestimated concepts which are however positionally justified. The entire package includes 29 theoretical chapters, 30 interactive test positions and 8 model games.
This unique package provides a complete overview of the Makagonov System against King's Indian Defence.

The complete package includes 1 structure article, 26 theoretical chapters and 60 interactive test positions.
In two database, GM Mihail Marin covers Queen's Gambit Declined for Black. True to his style, the author tries to make the repertoire as practical as possible.

In two databases, GM Michael Roiz provides you with a lifetime repertoire against Ruy Lopez. In all the lines, he suggests positionally justified reliable solutions. In many variations, he goes for new concepts or revives well forgotten old approaches.

This package by GM Arturs Neiksans includes three databases which provide you with a complete repertoire against the Sicilian Defence. Almost all the variations are based on a subtle positional understanding and do not require memorization of many forced lines.

This package includes three databases in which the Turkish grandmaster Burak Firat builds a complete repertoire for Black. The author often seeks dynamic options, not shying away from material sacrifices to solve opening problems or even take over the initiative with Black early in the game. Some of his novelties will have an added surprise value, as the opponent has likely not analyzed them in depth, or at all. In more solid variations, he offers sound positional advice when necessary, such as which plans to follow, which pieces to exchange, and which move orders to go for and which to avoid.
