The Diemer-Duhm-Gambit (DDG) is a chess opening that starts either with the moves ( see also : chess notation )
- 1. d2 – d4 d7 – d5 2. e2 – e4 e7 – e6 3. c2 – c4 !? (via the Rejected Blackmar Diemer Gambit ),
- 1. e2 – e4 e7 – e6 2. d2 – d4 d7 – d5 3. c2 – c4 !? (via the French Defense ),
- 1. d2 – d4 d7 – d5 2. c2 – c4 e7 – e6 3. e2 – e4 !? (via the Queen's Gambit Rejected ) or
- 1. e2 – e4 c7 – c6 2. d2 – d4 d7 – d5 3. c2 – c4 !? (via Caro-Kann ) begins.
The gambit is accepted if Black plays 3.… dxe4, the main line continues with 4. Nb1 – c3 Ng8 – f6 5. f2 – f3. After 5. f2 – f3 the gambit is divided into three main variants, the Kmoch variant 5.… Bf8 – b4, the Keres variant 5.… c7 – c5 and the exchange variant 5.… e4xf3.
The name of the opening goes back to the German chess player Andreas Duhm (1883–1975), who introduced it to practice in local and correspondence chess between 1907 and 1911 . In 1948 the German master Emil Joseph Diemer , the "father" of the Blackmar Diemer gambit, used this gambit for the first time.
The Diemer-Duhm-Gambit is a double-edged opening, which, like the Blackmar-Diemer-Gambit, is based on the emerging white attack. Diemer himself, however, considered the Alapin-Diemer gambit (3rd Be3) to be stronger in the French defense and played the Diemer-Duhm gambit especially against the Caro-Kann opening .
