Since Capablanca had won the New York 1927 chess tournament overwhelmingly and had never lost a game to Alekhine, most pundits regarded the Cuban as the clear favorite in their World Chess Championship 1927 match. But Alekhine won the match, played from September to November 1927 at Buenos Aires, by 6 wins, 3 losses, and 25 draws—the longest formal World Championship match until the contest in 1984–85 between Anatoly Karpov and Garry Kasparov. Alekhine's victory surprised almost the entire chess world. After Capablanca's death, Alekhine expressed surprise at his own victory, since in 1927 he had not thought he was superior to Capablanca, and he suggested that Capablanca had been overconfident. Capablanca entered the match with no technical or physical preparation, while Alekhine got himself into good physical condition and had thoroughly studied Capablanca's play. According to Kasparov, Alekhine's research uncovered many small inaccuracies, which occurred because Capablanca was unwilling to concentrate intensely. Vladimir Kramnik commented that this was the first contest in which Capablanca had no easy wins. Luděk Pachman suggested that Capablanca, who was unaccustomed to losing games or to any other type of setback, became depressed over his unnecessary loss of the 11th game in a grueling endgame featuring errors by both players. The match became somewhat notorious for its extremely lopsided use of the Queen's Gambit Declined; all games after the first two used this opening, and Capablanca's defeat has been partially attributed to his unwillingness to attempt any other openings.
