Blackmar-Diemer Gambit Accepted: Ritter Defense
Overview
Blackmar-Diemer Gambit Accepted: Ritter Defense belongs to the gambit family of chess openings (ECO D00, Closed & Semi-Closed Games). It trades material for attacking chances — a classic trade-off that has fascinated players from the Romantic era to modern correspondence chess.
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 10 plies of play, with the move sequence 1. d4 d5 2. e4 dxe4 3. Nc3 Nf6 4. f3 exf3 5. Nxf3 b6.
The line refines Blackmar-Diemer Gambit Accepted, which traces back to the root opening Queen's Pawn Game.
