Blackmar-Diemer Gambit
Overview
Blackmar-Diemer Gambit 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.
Play reaches this position via 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6, after 6 plies of opening development.
It is a variation of Blackmar-Diemer Gambit, which itself descends from the root opening Queen's Pawn Game.
It is the root of 11 named variations, with Blackmar-Diemer Gambit Accepted, Blackmar-Diemer Gambit Declined: Brombacher Countergambit, Blackmar-Diemer Gambit Declined: Elbert Countergambit, and others among the most studied.
Below the direct variations, the full subtree contains 32 documented sub-variations.
