The 1951 World Chess Championship was played between Mikhail Botvinnik and David Bronstein in Moscow from March 15 to May 11, 1951. It was the first match played under the supervision of FIDE; and the first to use a qualifying system of an Interzonal and Candidates Tournament to choose a challenger - a system which stayed in place until 1993.

Botvinnik was the defending champion: he was 39 years old, had been a world leading player in the 1930s and World Champion since 1948. The challenger, David Bronstein, was 27 years old and relatively new to top-level competition.

The match ended in a 12–12 tie (5 wins each, and 14 draws), meaning Botvinnik retained the title of World Champion. Writing in 1973, Israel Horowitz described the match as "perhaps the most interesting match ever played for the world championship".

1948 Interzonal tournament

{{main|Interzonal tournament, Saltsjöbaden 1948}}

An interzonal tournament was held at Saltsjöbaden in Stockholm, Sweden, in July and August 1948. The top eight finishers qualified for the Candidates tournament.

The four players tied for sixth place were to have played off for three spots in the Candidates tournament, but Bondarevsky had to withdraw due to illness, so the other three qualified automatically.

1950 Candidates tournament

The 1950 Candidates tournament was held in Budapest, Hungary in April and May 1950. The players who finished second through fifth in the 1948 championship tournament (Smyslov, Keres, Reshevsky, and Euwe) were seeded directly into the tournament, along with Reuben Fine, who had been invited to the 1948 tournament but declined, and the top eight finishers from the Interzonal.

It has been written that the two American players, Reshevsky and Fine, were prevented from travelling to Hungary by the US State Department, with travel restrictions due to the Cold War;From Morphy to Fischer (Batsford, 1973), Israel Horowitz. p.138 However, Reshevsky said in 1991 that he could have gone but did not want to.[An Interview with Sam Reshevsky, by Hanon W. Russell], Chesscafe.com Euwe declined due to work commitments, and Bondarevsky due to illness.

The co-winners then played a 12-game match in Moscow in July and August 1950. In the event of another tie, the first decisive game would determine Botvinnik's challenger for the title.

Bronstein thus earned the right to challenge the reigning champion.

= Boleslavsky's strategy=

Going into the final round of the Candidates tournament, Boleslavsky had a half point lead over Bronstein. Boleslavsky had white against Stahlberg, and offered a short draw when he was in a good position, which Stahlberg accepted.[http://www.chessgames.com/perl/chessgame?gid=1125596 Isaac Boleslavsky vs Gideon Stahlberg Budapest Candidates (1950)], Chessgames.com This gave Bronstein the opportunity to catch him, which he did, with a brilliant win against Keres.[http://www.chessgames.com/perl/chessgame?gid=1033804 David Bronstein vs Paul Keres Budapest Candidates (1950)], Chessgames.com It has been said, by both Bronstein and by Yuri Averbakh, that Boleslavsky allowed Bronstein to catch him. Averbakh said that Boleslavsky had a very poor record against Botvinnik, and hoped that a tie would mean a 3-way match between Botvinnik, Boleslavsky and Bronstein, although this did not eventuate.[https://web.archive.org/web/20080227105124/http://www.chesscafe.com/text/skittles181.pdf Yuri Averbakh: An Interview with History Part 1], Taylor Kingston, Chesscafe.com, 2002

It has also been speculated that the result of the Bronstein-Boleslavsky match was pre-arranged by the contestants.[http://en.chessbase.com/post/shattered-illusions-genna-sosonkos-the-rise-and-fall-of-david-bronstein Shattered illusions: "The Rise and Fall of David Bronstein"], Chessbase, 10/25/2017

| In Game 6, Bronstein (white) made one of the worst ever blunders in world championship play. He played 57 Kc2??, apparently expecting 57...Kf3 58 Ne6 e2 59 Nd4+ (however this line also leads to a win for black with correct play), but resigned when Botvinnik (black) played 57...Kg3, after which 59 Nd4 is not check. 57 Ne6+ was a simple draw. The blunder so upset Bronstein that he played weakly, and lost, in Game 7.
