Blackmar-Diemer Gambit Accepted: Gunderam Defense, Stader Variation
Overview
Blackmar-Diemer Gambit Accepted: Gunderam Defense, Stader Variation is a sacrificial opening line filed under ECO D00 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 is reached after 14 plies of play, with the move sequence 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 Bf5 6. Ne5 e6 7. g4 Be4.
In the opening tree, this line branches off from Blackmar-Diemer Gambit Accepted: Gunderam Defense, part of the broader Queen's Pawn Game system.
