Budapest 1950 Candidates Tournament

◈A new road to the title

When Alexander Alekhine died as reigning champion in 1946, FIDE took charge of the world title. A match-tournament in 1948 crowned Mikhail Botvinnik, and from then on the champion would defend every three years against a challenger produced by a fixed cycle of zonal, interzonal and Candidates events. Budapest 1950 was the first of those Candidates tournaments — the inaugural link in a chain that would run for decades.

Ten players contested a double round-robin of eighteen games each, organised by FIDE: David Bronstein, Isaak Boleslavsky, Vasily Smyslov, Paul Keres, Miguel Najdorf, Alexander Kotov, Gideon Ståhlberg, Andor Lilienthal, László Szabó and Salo Flohr. First place — and it alone — carried the right to challenge Botvinnik.

◈A tie and a play-off

For most of the event Boleslavsky set the pace; after sixteen rounds he led Bronstein by a full point. Then he slowed, and a quick final-round draw with Ståhlberg let his rival close the gap. Bronstein won in round seventeen and defeated Keres in the last round to finish level, both men on 12/18, two points clear of Smyslov in third.

The regulations carried no tiebreak, so Bronstein and Boleslavsky played a match in Moscow in the summer of 1950. After the scheduled twelve games it stood 6–6; the rules now said the next decisive result would settle it. The thirteenth game was drawn, and in the fourteenth Bronstein won with the black pieces to take the match 7½–6½ and become Botvinnik's challenger. In later years Bronstein suggested that the tournament's finish had not been wholly sporting — a shadow noted in ChessBase's history of the early Candidates — but the play-off result stood.

◈What followed

Bronstein carried his form into the 1951 World Championship match, leading Botvinnik 11½–10½ after twenty-two games before losing the twenty-third; the match finished 12–12 and the champion kept his title on the drawn score. Boleslavsky, who had shared first at Budapest, never came so close again. The tournament format born here — an all-play-all to choose the challenger — defined the world-championship cycle through the great Candidates events of the 1950s.
