The Chess Lion. Polish-Argentine grandmaster among the world's top ten for decades. The Najdorf Sicilian is named after him and remains a cornerstone of opening theory.
Miguel Najdorf was already a strong Polish master in 1939 when he traveled to Buenos Aires for the Chess Olympiad. And was stranded there by the German invasion of Poland. He stayed in Argentina, learned Spanish, became an Argentine citizen, and lost his entire family in the Holocaust. He poured his grief into chess and into staggering blindfold simultaneous exhibitions, partly hoping that publicity would reach any surviving relatives. He played the Sicilian Defence with such depth and conviction that the variation beginning 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6 became known universally as the Najdorf, one of the most important opening lines in chess. He remained world-class into his sixties.
Notable: The Najdorf Variation of the Sicilian (5...a6) bears his name and is one of the most-played openings in modern chess. Set a blindfold simultaneous record of 45 boards in 1947. Argentine Champion seven times.
