José Raúl Capablanca

José Raúl Capablanca y Graupera (19 November 1888 – 8 March 1942) was a Cuban chess player who was the third 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 the Castillo del Príncipe, 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 Sebastián 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 February 10, 1916 to March 21, 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 good results, but also showed symptoms of high blood pressure. 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 influenced the play of future world champions Bobby Fischer and Anatoly Karpov.

Childhood
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.

Early adult career
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.

World title contender
In 1911, Capablanca challenged Lasker for the World Chess Championship. Lasker accepted his challenge while proposing 17 conditions for the match. Capablanca objected to some of the conditions, which favored Lasker, and the match did not take place. In 1913, Capablanca won a tournament in New York with 11/13, half a point ahead of Marshall. Capablanca then finished second to Marshall in Havana, scoring 10 out of 14 and losing one of their individual games. The 600 spectators naturally favored their native hero, but sportingly gave Marshall "thunderous applause". In a tournament in New York in 1913, at the Rice Chess Club, Capablanca won all 13 games.

In September 1913, Capablanca accepted a job in the Cuban Foreign Office, which made him financially secure for life. Hooper and Whyld write, "He had no specific duties, but was expected to act as a kind of ambassador-at-large, a well-known figure who would put Cuba on the map wherever he travelled." His first instructions were to go to Saint Petersburg, where he was due to play in a major tournament. On his way, he gave simultaneous exhibitions in London, Paris and Berlin, where he also played two-game matches against Richard Teichmann and Jacques Mieses, winning all four games. In Saint Petersburg, he played similar matches against Alexander Alekhine, Eugene Znosko-Borovsky and Fyodor Duz-Chotimirsky, losing one game to Znosko-Borovsky and winning the rest.

The St. Petersburg 1914 chess tournament was the first in which Capablanca confronted Lasker under tournament conditions. This event was arranged in an unusual way: after a preliminary single round-robin tournament involving 11 players, the top five were to play a second stage in double round-robin format, with total scores from the preliminary tournament carried forward to the second contest. Capablanca placed first in the preliminary tournament, 1½ points ahead of Lasker, who was out of practice and had made a shaky start. Despite a determined effort by Lasker, Capablanca still seemed on course for ultimate victory. But in their second game of the final, Lasker reduced Capablanca to a helpless position and Capablanca was so shaken by this that he blundered away his next game to Tarrasch. Lasker then won his final game, against Marshall, thus finishing half a point ahead of Capablanca and 3½ ahead of Alekhine. Alekhine commented:

His real, incomparable gifts first began to make themselves known at the time of St. Petersburg, 1914, when I too came to know him personally. Neither before nor afterwards have I seen—and I cannot imagine as well—such a flabbergasting quickness of chess comprehension as that possessed by the Capablanca of that epoch. Enough to say that he gave all the St. Petersburg masters the odds of 5–1 in quick games—and won! With all this he was always good-humoured, the darling of the ladies, and enjoyed wonderful good health—really a dazzling appearance. That he came second to Lasker must be entirely ascribed to his youthful levity—he was already playing as well as Lasker.

After the breakdown of his attempt to negotiate a title match in 1911, Capablanca drafted rules for the conduct of future challenges, which were agreed to by the other top players at the 1914 Saint Petersburg tournament, including Lasker, and approved at the Mannheim Congress later that year. The main points were: the champion must be prepared to defend his title once a year; the match should be won by the first player to win six or eight games, whichever the champion preferred; and the stake should be at least £1,000 (worth about £26,000 or $44,000 in 2013 terms ).

During World War I
World War I began in midsummer 1914, bringing international chess to a virtual halt for more than four years. Capablanca won tournaments in New York in 1914, 1915, 1916 (with preliminary and final round-robin stages) and 1918, losing only one game in this sequence. In the 1918 event, Marshall, playing Black against Capablanca, unleashed a complicated counterattack, later known as the Marshall Attack, against the Ruy Lopez opening. It is often said that Marshall had kept this secret for use against Capablanca since his defeat in their 1909 match; however, Edward Winter discovered several games between 1910 and 1918 where Marshall passed up opportunities to use the Marshall Attack against Capablanca; and an 1893 game that used a similar line. This gambit is so complex that Garry Kasparov used to avoid it, and Marshall had the advantage of using a. Nevertheless, Capablanca found a way through the complications and won. Capablanca was challenged to a match in 1919 by Borislav Kostić, who had come through the 1918 tournament undefeated to take second place. The match was to go to the first player to win eight games, but Kostić resigned the match after losing the first five. Capablanca considered that he was at his strongest around this time.

World Champion
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.

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 had also given 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.

Losing the title
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.

Post-championship and partial retirement
After losing the World Championship in late 1927, Capablanca played more often in tournaments, hoping to strengthen his claim for a rematch. From 1928 through 1931, he won six first prizes, also finishing second twice and one joint second. His competitors included rising stars such as Max Euwe and Isaac Kashdan, as well as players who had been established in the 1920s, but Capablanca and Alekhine never played in the same tournament during this period, and next met only at the Nottingham 1936 tournament, after Alekhine had lost the world title to Euwe the previous year. In late 1931, Capablanca also won a match (+2−0=8) against Euwe, whom Chessmetrics ranks sixth in the world at the time.

Despite these excellent results, Capablanca's play showed signs of decline: his play slowed from the speed of his youth, with occasional time trouble; he continued to produce many superb games, but also made some gross blunders. Chessmetrics nonetheless ranks Capablanca as the second strongest player in the world (after Alekhine) from his loss of the title through to autumn 1932, except for a brief appearance in the top place.

Alekhine's offer to play Capablanca in a rematch if $10,000 could be raised came to naught due to the Great Depression. After winning an event at New York in 1931, he withdrew from serious chess, perhaps disheartened by his inability to secure a rematch with Alekhine, and played only less serious games at the Manhattan Chess Club and. On 6 December 1933, Capablanca won all 9 of his games in one of the club's weekly rapid chess tournaments, finishing 2 points ahead of Samuel Reshevsky, Reuben Fine and Milton Hanauer.

It is from this period that the only surviving voiced film footage survives. He is with Euwe and Dutch radio sports journalist Han Hollander. Hollander asks Capablanca for his views on the upcoming world Championship match between Euwe and Alekhine in October of that year (1935). Capablanca replies: "Dr. Alekhine's game is 20% bluff. Dr. Euwe's game is clear and straightforward. Dr. Euwe's game—not so strong as Alekhine's in some respects—is more evenly balanced." Then Euwe gives his assessment in Dutch, explaining that his feelings alternated from optimism to pessimism, but in the previous ten years, their score had been evenly matched at 7–7.

Return to competitive chess
At first Capablanca did not divorce his first wife, as he had not intended to remarry. Olga, Capablanca's second wife, wrote that she met him in the late spring of 1934; by late October the pair were deeply in love, and Capablanca recovered his ambition to prove he was the world's best player. In 1938 he divorced his first wife and married Olga on 20 October, about a month before the AVRO tournament.

Starting his comeback at the Hastings tournament of 1934–35, Capablanca finished fourth, although coming ahead of Mikhail Botvinnik and Andor Lilienthal. He placed second by ½ point in the Margate tournaments of 1935 and 1936. At Moscow 1935 Capablanca finished fourth, 1 point behind the joint winners, while Lasker's third place at the age of 66 was hailed as "a biological miracle." The following year, Capablanca won an even stronger tournament in Moscow, one point ahead of Botvinnik and 3½ ahead of Salo Flohr, who took third place; A month later, he shared first place with Botvinnik at Nottingham, with a score of (+5−1=8), losing only to Flohr. The loss to Flohr was because of being disturbed while in time trouble by the bystander Euwe. Alekhine placed sixth, only one point behind the joint winners. These tournaments of 1936 were the last two Lasker played, and the only ones in which Capablanca finished ahead of Lasker, now 67. During these triumphs Capablanca began to suffer symptoms of high blood pressure. He tied for second place at Semmering in 1937, then could only finish seventh of the eight players at the 1938 AVRO tournament, an elite contest designed to select a challenger for Alekhine's world title.

Capablanca's high blood pressure was not correctly diagnosed and treated until after the AVRO tournament, and caused him to lose his train of thought towards the end of playing sessions. In 1940, he had extremely dangerous hypertension of 210 systolic/180 diastolic (hypertensive crisis is 180/120 or above, and even after treatment Capablanca had 180/130).

After winning at Paris in 1938 and placing second in a slightly stronger tournament at Margate in 1939, Capablanca played for Cuba in the 8th Chess Olympiad, in Buenos Aires, and won the gold medal for the best performance on the. While Capablanca and Alekhine were both representing their countries in Buenos Aires, Capablanca made a final attempt to arrange a World Championship match. Alekhine declined, saying he was obliged to be available to defend his adopted homeland, France, as World War II had just broken out. Capablanca announced in advance that he would not play Alekhine if their teams met.

Death


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 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. Emanuel 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.

Tributes
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.

Playing strength and style
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.

Statistical ranking systems place Capablanca high among the greatest players of all time. Nathan Divinsky and Raymond Keene's book Warriors of the Mind (1989) ranks him fifth, behind Garry Kasparov, Anatoly Karpov, Bobby Fischer and Mikhail Botvinnik—and immediately ahead of Emanuel Lasker. In his 1978 book The Rating of Chessplayers, Past and Present, Arpad Elo gave retrospective ratings to players based on their performance over the best five-year span of their career. He concluded that Capablanca was the strongest of those surveyed, with Lasker and Botvinnik sharing second place. Chessmetrics (2005) is rather sensitive to the length of the periods being compared, and ranks Capablanca between third and fourth strongest of all time for peak periods ranging in length from one to 15 years. Its author, the statistician Jeff Sonas, concluded that Capablanca had more years in the top three than anyone except Lasker, Karpov and Kasparov—though Alekhine had more years in the top two positions. A 2006 study found that Capablanca was the most accurate of all the World Champions when compared with computer analysis of World Championship match games. This analysis was criticized for using a second-rank chess program, Crafty, modified to limit its calculations to six moves by each side, and for favoring players whose style matched that of the program; however a 2011 computer analysis by Bratko and Guid using the stronger engines Rybka 2 and Rybka 3 found similar results to the 2006 Crafty analysis for Capablanca.

Boris Spassky, World Champion from 1969 to 1972, considered Capablanca the best player of all time. Bobby Fischer, who held the title from 1972 to 1975, admired Capablanca's "light touch" and ability to see the right move very quickly. Fischer reported that in the 1950s, older members of the Manhattan Chess Club spoke of Capablanca's performances with awe.

Capablanca excelled in simple positions and endgames, and his positional judgment was outstanding, so much so that most attempts to attack him came to grief without any apparent defensive efforts on his part. But he could play great tactical chess when necessary—most famously in the 1918 Manhattan Chess Club Championship tournament, when Marshall sprang a deeply analyzed on him, which he refuted while playing under the normal time limit (although ways have since been found to strengthen the Marshall Attack). He was also capable of using aggressive tactical play to drive home a positional advantage, provided he considered it safe and the most efficient way to win, for example against Spielmann in the 1927 New York tournament.

Influence on the game
Capablanca founded no school per se, but his style influenced world champions Fischer, Karpov, and Botvinnik. Alekhine received schooling from Capablanca in positional play before their fight for the world title made them bitter enemies.

As a chess writer, Capablanca did not present large amounts of detailed analysis, instead focusing on the critical moments in a game. His writing style was plain and easy to understand. Botvinnik regarded Capablanca's book Chess Fundamentals as the best chess book ever written. Capablanca in a lecture and in his book A Primer of Chess pointed out that while the bishop was usually stronger than the knight, queen and knight was usually better than queen and bishop, especially in endings—the bishop merely mimics the queen's diagonal move, while the knight can immediately reach squares the queen cannot. Research is divided over Capablanca's conclusion: in 2007, Glenn Flear found little difference, while in 1999, Larry Kaufman, analysing a large database of games, concluded that results very slightly favored queen plus knight. John Watson wrote in 1998 that an unusually large proportion of queen and knight versus queen and bishop endings are drawn, and that most decisive games are characterized by the winning side having one or more obvious advantages in that specific game.

Personality
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.

In an interview in 1925, Capablanca denied reports that he thought chess had already currently reached its limit because it was easy for top players to obtain a draw. He was concerned, however, that the accelerating development of chess technique and opening knowledge might cause such stagnation in 50 years. Hence, he suggested the adoption of a 10×8 board with two extra pieces per side:
 * [[Image:Chess cll44.png|Chancellor|30px]] a chancellor that combines the movements of a rook and a knight;
 * [[Image:Chess all44.png|Archbishop|30px]] an archbishop that combines the movements of a bishop and a knight. This piece would be able to deliver checkmate on its own, which none of the conventional pieces can do, but checkmate cannot be forced without the help of its own king. He thought this would prevent technical knowledge from becoming such a dominant factor, at least for a few centuries.

Capablanca and Edward Lasker experimented with 10×10 and 10×8 boards, using the same expanded set of pieces. They preferred the 8- version as it encouraged combat to start earlier, and their games typically lasted 20 to 25 moves. Contrary to the claims of some critics, Capablanca proposed this variant while he was world champion, not as sour grapes after losing his title.

Similar 10×8 variants had previously been described in 1617 by Pietro Carrera and in 1874 by Henry Bird, differing only in how the new pieces were placed in each side's back row. Subsequent variants inspired by Capablanca's experimentation have been proposed, including Grand Chess (a 10×10 board with pawns on the third rank) and Embassy Chess (the Grand Chess setup on a 10×8 board).
