Queen's Gambit Declined: Harrwitz Attack
Overview
Queen's Gambit Declined: Harrwitz Attack is a sacrificial opening line filed under ECO D37 in the Closed & Semi-Closed Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.
The Closed & Semi-Closed Games group covers closed and semi-closed games — 1.d4 systems characterised by long strategic manoeuvring rather than early tactics.
It begins with 19 plies and takes 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 Be7 5. Bf4 O-O 6. e3 c5 7. dxc5 Bxc5 8. Qc2 Nc6 9. a3 Qa5 10. O-O-O to reach the canonical position.
In the opening tree, this line branches off from Queen's Gambit Declined: Harrwitz Attack, Main Line, part of the broader Queen's Gambit Declined: Three Knights Variation system.
