GM Repertoire against the Slav  Updated 

Slav defense is one of the most solid defenses against the queen's pawn first move, creating a strong and sometimes impregnable pawn chain that stretches from b7 to f7, with d5 square at its peak. In general black also wants to get his light-squared bishop out to f5 or g4, so as not to be bounded by this pawn chain and to exert pressure on white's center. On the other hand, black is not ambitious in a sense of challenging white's central domination early in the opening with pawn breaks such as c5 or e5 that we see in some other openings, so white usually enjoys a slight pressure within the first 5-15 moves.
