The most famous chess tournament

Which is the most famous chess tournament in the chess history?

The AVRO tournament was held in the Netherlands in 1938, sponsored by the Dutch broadcasting company Algemeene Vereeniging Radio Omroep. Eight of the world's top players took part: World Champion Alexander Alekhine, former champions José Raúl Capablanca and Max Euwe, and potential challengers Mikhail Botvinnik, Paul Keres, Reuben Fine, Samuel Reshevsky and Salo Flohr. Keres and Fine tied for first place, with Keres winner on tiebreak by virtue of his 1.5-0.5 score in their individual games.

The tournament was apparently organised in the hope that it would provide a challenger to Alekhine, but it was not an official Candidates Tournament. However, when FIDE organised its 1948 match tournament for the world title after Alekhine's death in 1946, it invited the six surviving AVRO participants (Capablanca had also died), except that Flohr was replaced by Vasily Smyslov.
