Complete Caro - Kann Repertoire for Black - Part 3

In the third part of his Caro-Kann trilogy, GM Firat covers the Panov Аttack, Exchange Variation and minor sidelines for White on moves 2 and 3. He remains true to his investigative approach, uncovering new ideas and reviving forgotten development systems in virtually every variation. He 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.

Complete Najdorf Repertoire for Black - Part 3

The third and final database covers some of the most dangerous and topical systems against the Najdorf as well as all the sidelines. You will find a complete repertoire against the following moves: 6.h3, 6.Be3, 6.a3, 6.h4, 6.Bd3, 6.Nf3, 6.Qf3, 6.Qe2, and 6.Qd3. While 6.h3 and 6.Be3 are considered to be a mainstream theory, other moves are interesting sidelines. In the past few years, the approach in the opening has changed a little, and people are now looking to get a playable position with interesting possibilities instead of going for theoretical discussions and long forced lines (We may want to call it the "Magnus Carlsen" effect!). Due to this new approach, White players switched to less exploited fields in order to pose new problems for Black in the Najdorf. We will see that despite those lines not being concrete or so aggressive-looking as the ones analyzed in database 2, Black should be aware of them as to avoid getting into trouble. The database consists of 3 sections - Typical Pawn Structures, Theoretical Section and Test Section.
