a letter in Chess Life magazine from a witness to the autopsy stated that choking on meat was the actual cause of death. At autopsy, a three-inch-long piece of unchewed meat was discovered blocking his windpipe. Some have speculated that he was murdered by a French "death squad". A few years later, Alekhine's son, Alexander Alekhine, Jr., said that "the hand of Moscow reached his father". Kevin Spraggett, a Canadian Grandmaster who has lived in Portugal since the late 1980s and has thoroughly investigated Alekhine's death, favors this possibility. Spraggett makes a case for the manipulation of the crime scene and the autopsy by the Portuguese secret police PIDE. He believes that Alekhine was murdered outside his hotel room, probably by Soviet agents. Alekhine's burial was sponsored by FIDE, and the remains were transferred to the Cimetière du Montparnasse, Paris, France, in 1956. His gravestone suffered heavy damage by a cyclone on 26 December 1999. The headstone monument was blown over, shattered and fell on the main gravestone. It was later restored. Assessment Playing strength and style Alekhine's peak period was in the early 1930s, when he won almost every tournament he played, sometimes by huge margins. Afterward, his play declined, and he never won a top-class tournament after 1934. After Alekhine regained his world title in 1937, there were several new contenders, all of whom would have been serious challengers. Alekhine was one of the greatest attacking players and could apparently produce combinations at will. What set him apart from most other attacking players was his ability to see the potential for an attack and prepare for it in positions where others saw nothing. Rudolf Spielmann, a master tactician who produced many brilliancies, said, "I can see the combinations as well as Alekhine, but I cannot get to the same positions." Dr. Max Euwe said, "Alekhine is a poet who creates a work of art out of something that would hardly inspire another man to send home a picture post-card." An explanation offered by Réti was, "he beats his opponents by analysing simple and apparently harmless sequences of moves in order to see whether at some time or another at the end of it an original possibility, and therefore one difficult to see, might be hidden." John Nunn commented that "Alekhine had a special ability to provoke complications without taking excessive risks", and Edward Winter called him "the supreme
