Blackmar-Diemer Gambit Declined: Lamb Defense
Overview
Blackmar-Diemer Gambit Declined: Lamb Defense 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 begins with 8 plies and takes 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 Nc6 to reach the canonical position.
In the opening tree, this line branches off from Blackmar-Diemer Gambit, part of the broader Queen's Pawn Game system.
Use the board to walk through every move, check how the position has scored on Lichess, or take it head-to-head against Stockfish.
