World Championship 1951: Botvinnik – Bronstein

David Bronstein, chess's great imaginative rebel, came within a single game of dethroning Botvinnik — then faltered at the last, losing the twenty-third game and drawing the finale. The match finished tied 12–12, and under the rules the champion kept his crown.

◇The imaginative challenger

Bronstein earned his shot by winning the 1950 Budapest Candidates, and his inventive, risk-taking chess could hardly have been more different from Botvinnik's cool, scientific approach. The champion had also barely played in the three years since winning the title in 1948, and it showed.

The result was a see-sawing contest between two utterly different chess minds.

◇One game from the title

Bronstein led by a point with only a few games to play — needing merely to hold — but lost the twenty-third game and could only draw the twenty-fourth, leaving the match level at 12–12. The drawn-match rule kept Botvinnik champion; the challenger's final tally was +5−5=14.

The near miss is still one of chess's great mysteries: Bronstein later hinted, without saying so plainly, that pressure from outside the board had affected the result, and historians still argue about how freely the deciding games were played.
