In 1929, a World Chess Championship was played between challenger Efim Bogoljubow and titleholder Alexander Alekhine. The match was held in Wiesbaden, Heidelberg and Berlin in Germany, and the Hague, Rotterdam and Amsterdam in the Netherlands, from September 6 to November 12. Alekhine retained his title.
Alekhine had been world champion since his 1927 victory over José Raúl Capablanca.
In 1928, Bogoljubov won a major tournament at Bad Kissingen, ahead of Capablanca and most other leading players of the day except for Alekhine. [1] Following this win, he challenged Alekhine for the world title. There was also an alternative offer of a return match against Capablanca in Bradley Beach, New Jersey, U.S. [2]
Under the rules at the time, the champion chose the challenger, and Alekhine chose to play a match against Bogoljubov.
The first player to win six games and score more than 15 points would be champion.
