The extraordinary photograph at the right shows Alexander Alekhine, world champion for 17 years, as he was found dead in a Lisbon hotel room in March 1946. His death, officially listed as accidental, was never fully explained. One of the most enigmatic of all masters, Alekhine was a White Russian officer but friendly with Bolsheviks; he was a French citizen and hero but also a Nazi collaborator. Winning the title from Capablanca in 1927, Alekhine lost it to Dr. Max Euwe of The Netherlands in 1935, won it back and kept it because Euwe would not play in Nazi tournaments. It was only after Alekhine's death that an international tournament in Moscow cleared the air enough to leave the vacated title with Botvinnik.
