As an adult, Capablanca lost only 34 serious games. He was undefeated from 10 February 1916, when he lost to Oscar Chajes in the New York 1916 tournament, to 21 March 1924, when he lost to Richard Réti in the New York International tournament. During this streak, which included his 1921 World Championship match against Lasker, Capablanca played 63 games, winning 40 and drawing 23. In fact, only Marshall, Lasker, Alekhine and Rudolf Spielmann won two or more serious games from the mature Capablanca, though in each case, their overall lifetime scores were minus (Capablanca beat Marshall +20−2=28, Lasker +6−2=16, Alekhine +9−7=33), except for Spielmann who was level (+2−2=8). Of top players, only Keres had a narrow plus score against him (+1−0=5). Keres's win was at the AVRO 1938 chess tournament, during which tournament Capablanca turned 50, while Keres was 22.
