Chess historian par excellence Edward Winter has translated a 1939 interview with Jose Raul Capablanca. (HT: Brian Karen) In it he speaks very favorably about Emanuel Lasker, Mikhail Botvinnik, Alexander Alekhine (though only in passing) and Paul Keres (but with some relatively minor and insightful reservations). To the surprise of no one who is familiar with Capablanca's autobiographical writings, he had some high praise for himself as well, acknowledging that he wasn't the player he was in 1918 (he rates his play then even higher than when he won the title in 1921) but fairly plausibly downplaying his failure at AVRO in 1938 to high blood pressure problems that were mostly under control at the Olympiad in 1939. (His last event, unfortunately, due to the outbreak of World War II and his premature death in 1942.)
Worth a read.
