Blackmar-Diemer Gambit Accepted: Gunderam Defense
Overview
Blackmar-Diemer Gambit Accepted: Gunderam Defense is a gambit, classified under ECO code D00 within the Closed & Semi-Closed Games family. As with all gambits, one side sacrifices material early — usually a pawn — in exchange for development, open lines, or initiative.
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 10 plies and takes 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 Bf5 to reach the canonical position.
It is a variation of Blackmar-Diemer Gambit Accepted, which itself descends from the root opening Queen's Pawn Game.
It continues primarily into one named line, Stader Variation.
