Opening Name: QGD: Semi-Tarrasch, 5.e3 Nc6 6.a3 dxc4
Moves: 1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Nf3 c5 5. e3 Nc6 6. a3 dxc4
Description: This line arises from the Semi-Tarrasch Defense, a dynamic variation of the Queen's Gambit Declined. Black’s move 6...dxc4 captures the pawn on c4, temporarily gaining material but also giving White the opportunity to recapture and accelerate development. White’s 6.a3 is a preparatory move aiming to recapture the pawn safely and prevent Black’s ...b4 expansion.
Characteristic: The capture on c4 is characteristic of the Semi-Tarrasch’s attempt to challenge White’s center while maintaining active piece play. Black accepts a slightly isolated or backward d-pawn in exchange for dynamic piece activity and pressure on White’s center.
Attacking or Defensive: From White’s perspective, the plan is generally attacking, focusing on regaining the pawn and building a strong central presence with moves like Bxc4 and e4 eventually. Black’s play is more counter-attacking, aiming to undermine White’s center and create counterplay on the queenside and center.
Center Control: This opening line is very much about control and contestation of the center. White seeks to maintain and strengthen central control, while Black challenges it actively by timely pawn breaks and piece pressure.
