The basic position of the Blackmar gambit after 3. f2 – f3
The Blackmar Gambit is a gambit , i.e. an opening of the game of chess . In the opening system of the ECO codes , it is classified under the key D00.
The Blackmar Gambit is introduced by the following moves ( see also: Chess notation ):
- 1. d2 – d4 d7 – d5 2. e2 – e4 d5xe4 3. f2 – f3
This gambit was invented by Armand Edward Blackmar in 1882 . At the age of 29 he published his first self-analyzed chess games with this move sequence. Just a few years later, however, it became clear that Black could gain an advantage with a counter-gambit (3.… e7 – e5), which is why the gambit is rarely found in tournament practice.
The Polish player Ignacy Popiel (called Ignaz von Popiel in Germany) considered the intermediate move 3. Nb1 – c3 in order to be able to take back the queen in the event of an exchange of queens with the knight. But he never wanted to play a gambit. The German chess player Emil Joseph Diemer expanded the Blackmar gambit with Popiel's 3rd Nb1 – c3 in the 20th century to create the Blackmar Diemer gambit , which found many fans in amateur circles, but is rarely seen at major tournaments these days .
variants
- After accepting the pawn sacrifice with 3.… e4xf3, White answers with
- 4. Ng1xf3 or
- 4. Qd1xf3
- The counter-gambit 3.… e7 – e5 aims to exchange queens after 4. d4xe5 Qd8xd1 +, after which White can no longer castle and Black has solved his opening problems.
A minor variant of the Blackmar Gambit is the Diemer-Rosenberg attack , which arises after moves 1. d4 d5 2. e4 dxe4 3. Be3. Here White initially delays the move f2 – f3 and blocks the black pawn with the bishop.
The Blackmar Gambit can develop from the Scandinavian Defense through the move change there 2. d2 – d4 .
