From Wikipedia I learned this:
In 1960, at the age of 23, Tal thoroughly defeated the relatively staid and strategic Mikhail Botvinnik in a World Championship match, held in Moscow, by 12.58.5 (six wins, two losses, and thirteen draws), making him the youngest-ever world champion (a record later broken by Garry Kasparov, who earned the title at 22). Botvinnik won the return match against Tal in 1961, also held in Moscow, 138 (ten wins to five, with six draws). In the period between the matches Botvinnik had thoroughly analyzed Tal’s style, and turned most of the return match’s games into slow wars of maneuver or endgames, rather than the complicated tactical melees which were Tal’s happy hunting ground. Tal’s chronic kidney problems contributed to his defeat, and his doctors in Riga advised that he should postpone the match for health reasons. Yuri Averbakh claimed that Botvinnik would agree to a postponement only if Tal was certified unfit by Moscow doctors, and that Tal then decided to play. His short reign atop the chess world made him one of the two so-called “winter kings” who interrupted Botvinnik’s long reign from 1948 to 1963 (the other was Smyslov, world champion 19571958).
Now you have learned it too!
Anyway, the point of this post is that here’s a pretty wild example of his style I came across the other day for those who like that kind of thing.
