Semi Slav g6 System by GM Magesh and GM Arun
In recent times due to advances in opening theory, Black is struggling to equalize in most of the systems. There is no opening for Black in which he can guarantee a comfortable position from which he can play for a win.
These days everybody has access to recent games, analysis from top Grandmasters, and opening books. If you think you can remember a lot of opening theory, it is easy to build your own repertoire with White and trouble the Black player, even if he is much stronger and higher rated, with your in-depth opening preparation. Even if Black is well prepared, White always has the choice of safe or drawish systems where Black can equalize but can never think of winning. Many lower rated players are always satisfied with a draw against higher rated players, and opening preparation will always help them to that end.
Facing a game with the Black pieces, a player who wants to play for a win can choose a rare system in which his opponent might not have great preparation. In this case, the game will not be decided by opening preparation. This week we shall see a new idea in the Semi-Slav which has been played by GM Sasikiran a couple of times.
