ECO code: D31
Opening Name: Semi-Slav: 4.cxd5 exd5 5.Nf3 Bf5
Moves: 1. d4 d5 2. c4 e6 3. Nc3 c6 4. cxd5 exd5 5. Nf3 Bf5
This line arises from the Semi-Slav Defense, where Black aims to solidify the center with pawns on d5 and c6. The move 5...Bf5 is characteristic because it develops the dark-squared bishop outside the pawn chain before playing ...e6, increasing Black's piece activity and avoiding the problem of a passive light-squared bishop often seen in the Slav structures.
From Black's perspective, this setup is somewhat balanced: it is both solid and seeks active piece play rather than purely defensive. Black challenges White's control of the center indirectly by maintaining a strong pawn presence and preparing for flexible development. White, on the other hand, typically plays more actively, aiming to leverage central and kingside space with moves like Qb3 or Bg5, so White’s play tends to be more attacking in nature.
Regarding the center, both sides contest it actively. White puts pressure on Black’s d5 pawn and looks to utilize central squares, while Black supports the center firmly with pawns on c6 and d5 and develops pieces to control key central and queenside squares. Thus, the opening involves a central struggle rather than a simple defensive or passive stance.
