Paul Keres was born in Narva, Estonia and lived there his entire life. He was very active in correspondence chess throughout his youth, and soon began to make a name for himself at over-the-board play as well with a series of tournament victories culminating with a tie for first at AVRO (1938). Keres was thrice Soviet Champion, in 1947 [rusbase-1], 1950 [rusbase-2], and 1951 [rusbase-3]. In 1948, Keres participated in the World Championship tournament to determine a successor to Alexander Alekhine, finishing joint third. This would turn out to be the only opportunity Keres would ever have to play for the world title--he finished second ex aequo or outright four times in the five Candidates' tournaments, from 1950 to 1962 inclusive, but never won.

Keres scored 13½/14 at the 11th Olympiad in Amsterdam 1954 (1) and in 1963, he won at Los Angeles http://www.worldchesslinks.net/eziq... (sharing first place with Tigran V Petrosian). Keres suffered a fatal heart attack in Helsinki on the way home from winning a tournament in Vancouver in 1975, at age 59.

Keres is the player who has defeated the largest number of world champions, no fewer than nine: Capablanca (http://www.chessgames.com/perl/ches... Alekhine http://www.chessgames.com/perl/ches... Euwe http://www.chessgames.com/perl/ches... Botvinnik http://www.chessgames.com/perl/ches... Smyslov http://www.chessgames.com/perl/ches... Tal http://www.chessgames.com/perl/ches... Petrosian http://www.chessgames.com/perl/ches... Spassky http://www.chessgames.com/perl/ches... and Fischer http://www.chessgames.com/perl/ches...

With his five second-place finishes in Candidates events and his results against world champions, Keres was often known as "Paul, the Second" and "The Uncrowned King".
