Blumenfeld Gambit

17 October 2010, Kuala Lumpur – Found an interesting chess article on Blumenfeld Gambit by Dr Alexander Alekhine and retranslated into Portugese by www.torre21.com and Richard Guerrero. Here is the chess article below:-

Benjamin Blumenfeld Markowich * 24.8.1884 † 5.3.1947 was a Russian chess master and chess theory.

Blumenfeld, a senior lawyer at the universities of Moscow and Berlin, was evaluated in the first decade of the last century, before World War I, as one of the best players in Moscow.

His greatest success was achieved when the completion of the 4th Russian Masters Tournament 1905/1906 in St. Petersburg, occupying, along with Akiba Rubinstein, the 2nd place of the standings.

Also in 1907 had to share second place in the International Tournament in Moscow.
In 1911, he became champion in Moscow, and after the October Revolution, attended the first tournament of the year 1920 in the Soviet state, which was called the Olympics of all the Russias. Occupied the 8th place. In 1925, split again, the 2nd and 3rd place of the standings in Moscow.
The creation of theoretical Blumenfeld was one of the cornerstones of the Soviet school of chess.
In his honor, the famous counter-gambit is named, Blumenfeld:

The basis of the positional gambit Blumenfeld counter after 4 ... b7-b5

The Blumenfeld gambit is a variant of the openings in chess. This gambit belongs to the Games "closed" and the code will be classified by ECO key: E10. Defense has its origin in India.
Each of its main variants begin with the moves: 1. d4 Nf6 2. c4 e6 3. Nf3 c5 4. d5 b5.

Even after extensive investigations, we could not move very little and could only confirm the data already known exactly.Could not find a picture of Blumenfeld, nor a group photo of the tournaments he attended.
Moreover, it could not be clarified until now because his name was used for Blumenfeld gambit.

At first, we thought it would have been logical to find many matches played in their application of gambit with your name. Unfortunately, the result was negative!
Now, do not continue to disappoint the faithful readers, we reproduce a match in which - presumably - was played for the first time "officially" Blumenfeld gambit, suitably explained by Dr. Alexander Alekhine, who won the match with black, and by the Catalan master Richard Guerrero.
