Everyone knows about the dominance of Garry Kasparov in chess, the World Championships he won, as well as many big tournaments! But here are some perhaps less well known facts about the great one:
In 1979, while still unrated, Kasparov won a strong tournament in Banja Luka, obtaining a provisional rating of 2595!
In 1980, he won the World Junior Championship in Dortmund and in the same year made the Soviet Olympiad team at the Malta Chess Olympiad!
Still a teenager, Kasparov tied for 1st at the Soviet Championship in 1981-1982!
In 1982, he won the Moscow Interzonal to qualify for the Candidates Tournament! He was around 19 at the time, the 2nd youngest to do so only after Fischer at 15 years old.
In January 1983, Kasparov was already the #2 ranked chess player in the world after only Anatoly Karpov, around only 4 years after he had his first provisional rating!
In January 1984, around 5 years after earning his 1st provisional rating, he became the #1 ranked player in the world!
1985 at age 22, he became the youngest ever undisputed World Chess Champion after defeating Anatoly Karpov!
Until he retired from chess in 2005, Garry Kasparov was ranked #1 for 225 out of 228 months!
Kasparov of course achieved a lot more than this but these are just some less known highlights of his incredible chess career!
I would say that he was a very dominant player in his era, no doubt about it!
