José Raúl Capablanca y Graupera (19 November 1888 – 8 March 1942) was a Cuban chess player who was world chess champion from 1921 to 1927.

A chess prodigy, he is widely renowned for his exceptional endgame skill and speed of play.

Capablanca was born in 1888 in Havana. He beat Cuban champion Juan Corzo in a match on 17 November 1901, two days before his 13th birthday. His victory over Frank Marshall in a 1909 match earned him an invitation to the 1911 San Sebastian tournament, which he won ahead of players such as Akiba Rubinstein, Aron Nimzowitsch and Siegbert Tarrasch. Over the next several years, Capablanca had a strong series of tournament results. After several unsuccessful attempts to arrange a match with then world champion Emanuel Lasker, Capablanca finally won the world chess champion title from Lasker in 1921. Capablanca was undefeated from 10 February 1916 to 21 March 1924, a period that included the world championship match with Lasker.

Capablanca lost the title in 1927 to Alexander Alekhine, who had never beaten Capablanca before the match. Following unsuccessful attempts to arrange a rematch over many years, relations between them became bitter. Capablanca continued his excellent tournament results in this period but withdrew from serious chess in 1931. He made a comeback in 1934, with some good results, but also showed symptoms of high blood pressure. His last major tournament was the AVRO tournament of 1938, where he performed disappointingly. He died in 1942 of a brain hemorrhage.

Capablanca excelled in simple positions and endgames; Bobby Fischer described him as possessing a "real light touch". He could play tactical chess when necessary, and had good defensive technique. He wrote several chess books during his career, of which Chess Fundamentals was regarded by Mikhail Botvinnik as the best chess book ever written. Capablanca preferred not to present detailed analysis but focused on critical moments in a game. His style of chess was influential in the play of future world champions Bobby Fischer and Anatoly Karpov.

Biography and career

José Raúl Capablanca, the second surviving son of a Spanish army officer, José María Capablanca, and a Spanish woman from Catalonia, Matilde María Graupera y Marín, was born in Havana on 19 November 1888. According to Capablanca, he learned to play chess at the age of four by watching his father play with friends, pointed out an illegal move by his father, and then beat his father. At the age of eight he was taken to Havana Chess Club, which had hosted many important contests, but on the advice of a doctor he was not allowed to play frequently. Between November and December 1901, he narrowly beat the Cuban Chess Champion, Juan Corzo, in a match. However, in April 1902 he came in fourth out of six in the National Championship, losing both his games with Corzo. 

In 1905 Capablanca easily passed the entrance examinations for Columbia College (New York), where he wished to play for Columbia's strong baseball team, and soon was starting shortstop on the freshman team. In the same year he joined the Manhattan Chess Club, and was soon recognized as the club's strongest player. He was particularly dominant in rapid chess, winning a tournament ahead of the reigning World Chess Champion, Emanuel Lasker, in 1906. He represented Columbia on top board in intercollegiate team chess. In 1908 he left the university to concentrate on chess.

According to Columbia University, Capablanca enrolled at Columbia's School of Mines, Engineering and Chemistry in September 1910, to study chemical engineering. Later, his financial support was withdrawn because he preferred playing chess to studying engineering. He left Columbia after one semester to devote himself to chess full-time.

Capablanca's skill in rapid chess lent itself to simultaneous exhibitions, and his increasing reputation in these events led to a US-wide tour in 1909. Playing 602 games in 27 cities, he scored 96.4%—a much higher percentage than, for example, Géza Maróczy's 88% and Frank Marshall's 86% in 1906. This performance gained him sponsorship for an exhibition match that year against Marshall, the US champion, who had won the 1904 Cambridge Springs tournament ahead of World Champion Emanuel Lasker and Dawid Janowski, and whom Chessmetrics ranks as one of the world's top three players at his peak. Capablanca beat Marshall, 15–8 (8 wins, 1 loss, 14 draws)—a margin comparable to what Lasker achieved against Marshall (8 wins, no losses, 7 draws) in winning his 1907 World Championship match. After the match, Capablanca said that he had never opened a book on chess openings. Following this match, Chessmetrics rates Capablanca the world's third strongest player for most of the period from 1909 through 1912.

Capablanca won six games and drew one in the 1910 New York State Championship. Both Capablanca and Charles Jaffe won their four games in the knock-out preliminaries and met in a match to decide the winner, who would be the first to win two games. The first game was drawn and Capablanca won the second and third games. After another grueling series of simultaneous exhibitions, Capablanca placed second, with 9½ out of 12, in the 1911 National Tournament at New York, half a point behind Marshall, and half a point ahead of Charles Jaffe and Oscar Chajes. Marshall, invited to play in a tournament at San Sebastián, Spain, in 1911, insisted that Capablanca also be allowed to play.

According to David Hooper and Ken Whyld, San Sebastián 1911 was "one of the strongest five tournaments held up to that time", as all the world's leading players competed except the World Champion, Lasker. At the beginning of the tournament, Ossip Bernstein and Aron Nimzowitsch objected to Capablanca's participation because he had not fulfilled the entry condition of winning at least third prize in two master tournaments. Capablanca won brilliantly against Bernstein in the very first round, more simply against Nimzowitsch, and astounded the chess world by taking first place, with six wins, one loss and seven draws, ahead of Akiba Rubinstein, Milan Vidmar, Marshall, Carl Schlechter and Siegbert Tarrasch, et al. His loss, to Rubinstein, was one of the most brilliant achievements of the latter's career. Some European critics grumbled that Capablanca's style was rather cautious, though he conceded fewer draws than any of the next six finishers in the event. Capablanca was now recognized as a serious contender for the world championship.

The Hastings Victory tournament of 1919 was the first international competition on Allied soil since 1914. The field was not strong, and Capablanca won with 10½ points out of 11, one point ahead of Kostić.

In January 1920, Lasker and Capablanca signed an agreement to play a World Championship match in 1921, noting that Capablanca was not free to play in 1920. Because of the delay, Lasker insisted that if he resigned the title, then Capablanca should become World Champion. Lasker had previously included in his agreement before World War I to play Akiba Rubinstein for the title a similar clause that if he resigned the title, it should become Rubinstein's. Lasker then resigned the title to Capablanca on 27 June 1920, saying, "You have earned the title not by the formality of a challenge, but by your brilliant mastery." When Cuban enthusiasts raised $20,000 to fund the match provided it was played in Havana, Lasker agreed in August 1920 to play there, but insisted that he was the challenger as Capablanca was now the champion. Capablanca signed an agreement that accepted this point, and soon afterwards published a letter confirming it.

The match was played in March–April 1921; Lasker resigned it after 14 games, having lost four and won none. Reuben Fine and Harry Golombek attributed the one-sided result to Lasker's mysteriously poor form. Fred Reinfeld mentioned speculations that Havana's humid climate weakened Lasker and that he was depressed about the outcome of World War I, especially as he had lost his life savings. On the other hand, Vladimir Kramnik thought that Lasker played quite well and the match was an "even and fascinating fight" until Lasker blundered in the last game. Kramnik explained that Capablanca was 20 years younger, a slightly stronger player, and had more recent competitive practice.

Edward Winter, after a lengthy summary of the facts, concludes, "The press was dismissive of Lasker's wish to confer the title on Capablanca, even questioning the legality of such an initiative, and in 1921 it regarded the Cuban as having become world champion by dint of defeating Lasker over the board." Reference works invariably give Capablanca's reign as titleholder as beginning in 1921, not 1920. The two challengers besides Capablanca to win the title without losing a game are Kramnik, in the Classical World Chess Championship 2000 against Garry Kasparov, and Magnus Carlsen in the World Chess Championship 2013 against Viswanathan Anand.

Capablanca won the London tournament of 1922 with 13 points in 15 games with no losses, ahead of Alekhine with 11½, Milan Vidmar (11), and Akiba Rubinstein (10½). During this event, Capablanca proposed the "London Rules" to regulate future World Championship negotiations: the first player to win six games would win the match; playing sessions would be limited to 5 hours; the time limit would be 40 moves in 2½ hours; the champion must defend his title within one year of receiving a challenge from a recognized master; the champion would decide the date of the match; the champion was not obliged to accept a challenge for a purse of less than US$10,000 (about $260,000 in 2006 terms); 20% of the purse was to be paid to the title holder and the remainder divided, 60% to the winner of the match, and 40% to the loser; the highest purse bid must be accepted. Alekhine, Efim Bogoljubow, Géza Maróczy, Richard Réti, Rubinstein, Tartakower and Vidmar promptly signed them. Between 1921 and 1923 Alekhine, Rubinstein and Nimzowitsch all challenged Capablanca, but only Alekhine could raise the money, in 1927.

In 1922, Capablanca also gave a simultaneous exhibition in Cleveland against 103 opponents, the largest in history up to that time, winning 102 and drawing one—setting a record for the best winning percentage ever in a large simultaneous exhibition.

After beginning with four draws, followed by a loss, Capablanca placed second at the New York 1924 chess tournament with the score of 14½/20 (+10−1=9), 1½ points behind Lasker, and 2½ ahead of third-placed Alekhine. Capablanca's defeat by Réti in the fifth round was his first in serious competition in eight years. He made another bad start at the Moscow 1925 chess tournament, and could only fight back to third place, two points behind Bogoljubow and ½ point behind Lasker. Capablanca won at Lake Hopatcong, 1926 with 6 points out of 8, ahead of Abraham Kupchik (5) and Maroczy (4½).

A group of Argentinian businessmen, backed by a guarantee from the president of Argentina, promised the funds for a World Championship match between Capablanca and Alekhine in 1927. Since Nimzowitsch had challenged before Alekhine, Capablanca gave Nimzowitsch until 1 January 1927, to provide a deposit in order to arrange a match. When this did not materialize, a Capablanca–Alekhine match was agreed, to begin in September 1927.

In the New York 1927 chess tournament, held from 19 February to 23 March 1927, six of the world's strongest masters played a quadruple round-robin, with the others being Alekhine, Rudolf Spielmann, Milan Vidmar, Nimzowitsch and Marshall, with Bogoljubow and Lasker absent. Before the tournament, Capablanca wrote that he had "more experience but less power" than in 1911, that he had peaked in 1919 and that some of his competitors had become stronger in the meantime. But Capablanca had overwhelming success: he finished undefeated with 14/20, winning the mini-matches with each of his rivals, 2½ points ahead of second-place Alekhine, and won the "best game" prize for a win over Spielmann.

In December 1921, shortly after becoming World Champion, Capablanca married Gloria Simoni Betancourt. They had a son, José Raúl Jr., in 1923 and a daughter, Gloria, in 1925. According to Capablanca's second wife, Olga, his first marriage broke down fairly soon, and he and Gloria had affairs. Both his parents died during his reign, his father in 1923 and mother in 1926.

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.

Immediately after winning the match, Alekhine announced that he was willing to give Capablanca a rematch, on the same terms that Capablanca had required as champion—the challenger must provide a stake of US$10,000, of which more than half would go to the defending champion even if he was defeated. Alekhine had challenged Capablanca in the early 1920s, but Alekhine could not raise the money until 1927. After Capablanca's death, Alekhine wrote that Capablanca's demand for a $10,000 stake was an attempt to avoid challenges. Negotiations dragged on for several years, often breaking down when agreement seemed in sight. Their relationship became bitter, and Alekhine demanded much higher appearance fees for tournaments in which Capablanca also played.

Not long before his death, his familial hypertension had shot up to the hazardous 200–240/160+. The day before his fatal stroke, his vascular specialist Dr. Schwarzer strongly advised him that his life was endangered unless he totally relaxed, but Capablanca said that he could not because his ex-wife and children had started court proceedings against him. The doctor blamed his death on "his troubles and aggravation".

On 7 March 1942, Capablanca was observing a skittles game and chatting with friends at the Manhattan Chess Club in New York City, when he asked for help removing his coat, and collapsed shortly afterward. Eminent physician Eli Moschcowitz administered first aid and then arranged an ambulance. He was taken to Mount Sinai Hospital, where he died at 6:00 AM the next day. Lasker had died in the same hospital only a year earlier. The cause of death was given as "a cerebral hemorrhage provoked by hypertension", in particular a hypertensive thalamic hemorrhage. The hospital admissions report stated:

When admitted to Mt. Sinai Hospital, the examination showed: Patient critically ill in deep coma, unreceptive to nocioceptive stimuli, unequal pupils with the left one dilated (fixed and unresponsive to light), left facial palsy, left hemiplegia, globally depressed tendinous reflexes and arterial tension 280/140. A lumbar puncture was performed which showed hemorrhagic cerebrospinal fluid (CSF) with a pressure of 500 mm of water.

The full autopsy, by Drs. Moschcowitz, Prill, and Levin, showed that the right thalamus was almost totally destroyed, and in its place was a hematoma 2 inches wide and 2 inches high. The whole ventricular system and cisterna magna were flooded with blood. The gyri were flattened and sulci narrowed, consistent with years of extreme hypertension. His heart was enlarged, 575 g instead of the normal 300–350 g, including 3 cm hypertrophy of left ventricle wall. This wall had a number of subendiocardial hemorrhages, which was later proved to be common in patients with severe intercranial hypertension. This caused the release of a large amount of vasoactive substances into the bloodstream, including acetylcholine and noradrenaline that caused these hemorrhages.

The lumbar puncture was a bad idea, as intracranial hypertension is now a well-known contraindication because it releases the pressure of the cerebrospinal fluid counteracting the herniating force of the hypertension. But neurosurgeon Orlando Hernández-Meilán has said that it made no difference, as Capablanca could not have been revived even if the best modern medicine had been available.

Capablanca was given a public funeral in Havana's Colón Cemetery on 15 March 1942.

Alekhine wrote in a tribute to Capablanca: "Capablanca was snatched from the chess world much too soon. With his death, we have lost a very great chess genius whose like we shall never see again." Lasker once said: "I have known many chess players, but only one chess genius: Capablanca."

An annual Capablanca Memorial tournament has been held in Cuba, most often in Havana, since 1962.

Early in his chess career, Capablanca received some criticism, mainly in Britain, for the allegedly conceited description of his accomplishments in his first book, My Chess Career. He therefore took the unprecedented step of including virtually all of his tournament and match defeats up to that time in Chess Fundamentals, together with an instructive group of his victories. Nevertheless, his preface to the 1934 edition of Chess Fundamentals is confident that the "reader may therefore go over the contents of the book with the assurance that there is in it everything he needs." Julius du Mont wrote that he knew Capablanca well and could vouch that he was not conceited. In du Mont's opinion, critics should understand the difference between the merely gifted and the towering genius of Capablanca, and the contrast between the British tendency towards modesty and the Latin and American tendency to say "I played this game as well as it could be played" if he honestly thought that was true. Capablanca himself said, in his author's note prefacing My Chess Career: "Conceit I consider a foolish thing, but more foolish still is the false modesty that vainly attempts to conceal which all facts tend to prove." Fischer also admired this frankness. Du Mont also said that Capablanca was rather sensitive to criticism, and chess historian Edward Winter documented a number of examples of self-criticism in My Chess Career.

Despite his achievements Capablanca appeared more interested in baseball than in chess, which he described as "not a difficult game to learn and it is an enjoyable game to play." His second wife, Olga, thought he resented that chess had dominated his life, and wished he could have studied music or medicine.
