Efim Bogoljubov: the aggressive challenger to the world throne

Confidence can be a double-edged weapon in chess. For Efim Bogoljubov, it was simply a weapon: his unlimited self-belief and aggression led him to contest the World Championship twice, making even Alekhine himself tremble.

Who was Bogoljubov

He was born on 14 April 1889 in a small town in the Russian Empire (today Ukraine). He learned chess young and soon stood out on the Russian circuit. In the 1920s, during a tournament in Germany, he decided to stay: he married a German woman and settled in the country, moving away from the Soviet Union.

The title challenger

Bogoljubov won major tournaments in the 1920s and 1930s and was considered the main rival of Alexander Alekhine, the world champion. He contested two matches for the title: in 1929 and 1934. He lost both, but his aggression made the games combative to the very end.

He’s credited with the famous line: “When I play White, I win because I play White; when I play Black, I win because I am Bogoljubov.”
