Typical Pawn Structure
By supporting d5 with ...c6 rather than ...e6, Black keeps the light-squared bishop's diagonal open, avoiding the passive bishop typical of the Queen's Gambit Declined. The structure stays flexible: Black often captures with ...dxc4 and follows with ...b5 to hold the pawn or develops the bishop actively before clarifying the center. Resulting middlegames range from solid symmetrical setups to dynamic positions with queenside pawn play.

History & Origin
The Slav Defense rose to prominence in the 1920s and 1930s, championed by a generation of Eastern European masters from whom it takes its name. It became a major battleground in the World Championship matches of Alekhine and Euwe and was later refined extensively in Soviet preparation. Vladimir Kramnik and many modern elite players have kept it at the forefront of theory as a flexible, fully sound answer to the Queen's Gambit.
Related Systems & Transpositions
The Slav is closely linked to the Semi-Slav, which adds ...e6 to combine Slav and Queen's Gambit Declined ideas. It belongs to the wider Queen's Gambit family and shares the central d5/c6 framework with the Caro-Kann's pawn skeleton.
