Queen's Gambit Declined: Semi-Tarrasch Defense, Main Line
Overview
Queen's Gambit Declined: Semi-Tarrasch Defense, Main Line is a sacrificial opening line filed under ECO D42 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.
Play reaches this position via 1. d4 Nf6 2. c4 e6 3. Nf3 d5 4. Nc3 c5 5. cxd5 Nxd5 6. e3 Nc6 7. Bd3, after 13 plies of opening development.
In the opening tree, this line branches off from Queen's Gambit Declined: Semi-Tarrasch Defense, Pillsbury Variation, part of the broader Queen's Gambit Declined: Three Knights Variation system.
