Aron Nimzowitsch - Jose Raul Capablanca, New York 1927 ++1. Aron Isaevich Nimzowitsch Aron Isaevich Nimzowitsch (born Aron Niemzowitsch and also known as Aaron Nimzovich) (November 7, 1886 - March 16, 1935) was a Latvian- born Danish unofficial chess grandmaster and a very influential chess writer. He was the foremost figure amongst the hypermoderns. ++1.A Life Born in Riga in Livonia, then part of the Russian empire, the Jewish German-speaking Nimzowitsch came from a wealthy family, where he learned chess from his father, who was a merchant. In 1904, he traveled to Berlin to study philosophy, but set aside his studies soon and began a career as a professional chess player that same year. He won his first international tournament at Munich 1906. Then, he tied for first with Alexander Alekhine at St. Petersburg 1913/14 (the eighth All-Russian Masters' Tournament). During the 1917 Russian Revolution, Nimzowitsch was in the Baltic war zone. He escaped being drafted into one of the armies by feigning madness, insisting that a fly was on his head. He then escaped to Berlin, and gave his first name as Arnold, possibly to avoid anti-Semitic persecution. Nimzowitsch eventually moved to Copenhagen in 1922, which coincided with his rise to the world chess elite, where he lived for the rest of his life in one small rented room. In Copenhagen, he won twice Nordic Chess Championship in 1924 and 1934. He obtained Danish citizenship and lived in Denmark, until his death in 1935. Although he had long suffered from heart trouble, his early death was unexpected, taken ill suddenly at the end of 1934, he lay bedridden for three months before dying of pneumonia. He is buried in Bispebjerg Cemetery in Copenhagen. ++1.B Chess career The height of Nimzowitsch's career was the late 1920s and early 1930s. Chessmetrics places him as the third best player in the world, behind Alexander Alekhine and Jose Capablanca, from 1927 to 1931. His most notable successes were first-place finishes at Copenhagen 1923, Marienbad 1925, Dresden 1926, Hannover 1926, and the Carlsbad 1929 chess tournament, and second place behind Alekhine at the San Remo 1930 chess tournament. Nimzowitsch never developed a knack for match play, though; his best match success was a draw with Alekhine, but the match was only two games long and was in 1914, thirteen years before Alekhine became world champion. Nimzowitsch never won against Capablanca, but fared better against Alekhine. He even beat Alekhine with the black pieces, in their short 1914 match at St. Petersburg. One of Nimzowitsch's most famous games is his celebrated immortal zugzwang game against Saemisch at Copenhagen 1923. Another game on this theme is his win over Paul Johner at Dresden 1926. When in form, Nimzowitsch was very dangerous with the black pieces, scoring many fine wins over top players. ++1.C Legacy Nimzowitsch is considered one of the most important players and writers in chess history. His works influenced numerous other players, including Savielly Tartakower, Milan Vidmar, Richard Reti, Akiba Rubinstein, Bent Larsen, and Tigran Petrosian, and his influence is still felt today. He wrote three books on chess strategy: Mein System (My System), 1925, Die Praxis meines Systems (The Practice of My System), 1929, commonly known as Chess Praxis, and Die Blockade (The Blockade), 1925. The last of these has just been reissued in a volume containing both the German original and the English translation published by Hardinge Simpole. However, much that is in it is covered again in Mein System. It is said that 99 out of 100 chess masters have read Mein System; consequently, most consider it to be Nimzowitsch's greatest contribution to chess. It sets out Nimzowitsch's most important ideas, while his second most influential work, Chess Praxis, elaborates upon these ideas, adds a few new ones, and has immense value as a stimulating collection of Nimzowitsch's own games, even when these games are more entertaining than instructive. Nimzowitsch's chess theories flew in the face of convention. While there were those like Alekhine, Emanuel Lasker, and even Capablanca who did not live by Tarrasch's rigid teachings, the acceptance of Tarrasch's ideas, all simplifications of the more profound work of Wilhelm Steinitz, was nearly universal. That the center had to be controlled by pawns and that development had to happen in support of this control -- the core ideas of Tarrasch's chess philosophy -- were things every beginner thought to be irrefutable laws of nature, like gravity. Nimzowitsch shattered these assumptions. He discovered such concepts as overprotection (the least important of his ideas from a modern standpoint though still interesting and sometimes applicable), control of the center by pieces instead of pawns, blockade, and prophylaxis -- playing to prevent the opponent's plans. He was also a leading advocate and exponent of the fianchetto development of the bishops. Nimzowitsch also formalised strategies using open files, outposts and invasion of the seventh rank, all of which are widely accepted today. Others had utilized such ideas in previous years, but he was the first to knit them together into a cohesive whole. Grandmaster (GM) Raymond Keene writes that Nimzowitsch "was one of the world's leading Grandmasters for a period extending over a quarter of a century, and for some of that time he was the obvious challenger for the world championship. ... (He was also) a great and profound chess thinker, second only to Steinitz, and his works- Die Blockade, My System and Chess Praxis-established his reputation as one of the father figures of modern chess." GM Robert Byrne called him "perhaps the most brilliant theoretician and teacher in the history of the game." GM Jan Hein Donner called Nimzowitsch "a man who was too much of an artist to be able to prove he was right and who was regarded as something of a madman in his time. He would be understood only long after his death." Many chess openings and variations are named after Nimzowitsch, the most famous being the Nimzo-Indian Defence (1. d4 Nf6 2. c4 e6 3. Nc3 Bb4) and the less often played Nimzowitsch Defence (1. e4 Nc6). Nimzowitsch biographer Grandmaster Raymond Keene and others have referred to 1. f4 followed by 2. b3 as the Nimzowitsch-Larsen Attack. Keene wrote a book about the opening with that title. All of these openings exemplify Nimzowitsch's ideas about controlling the center with pieces instead of pawns. Nimzowitsch was also vital in the development of two important systems in the French Defence, the Winawer Variation (in some places called the Nimzowitsch Variation; its moves are 1. e4 e6 2. d4 d5 3. Nc3 Bb4) and the Advance Variation (1. e4 e6 2. d4 d5 3. e5). He also pioneered two provocative variations of the Sicilian Defence, both regarded as dubious today: the Nimzowitsch Variation, 1. e4 c5 2. Nf3 Nf6, which invites 3. e5 Nd5, similarly to Alekhine's Defence, and 1. e4 c5 2. Nf3 Nc6 3. d4 cxd4 4. Nxd4 d5?! ++1.D Personality There are many entertaining anecdotes regarding Nimzowitsch--some less savory than others. For example, he once missed the first prize of a great rapid transit tournament in Berlin by losing to Sdmisch; immediately upon learning this, Nimzowitsch got up on a table and shouted "Gegen diesen Idioten muss ich verlieren!" ("That I should lose to this idiot!"). Nimzowitsch was annoyed by his opponents' smoking. A popular, but probably apocryphal, story is that once when an opponent laid a cigar on the table, he complained to the tournament arbiters, "he is threatening to smoke, and as an old player you must know that the threat is stronger than the execution". Nimzowitsch had lengthy and somewhat bitter dogmatic conflicts with Tarrasch over whose ideas constituted 'proper' chess. Nimzowitsch's vanity and faith in his ideas of overprotection provoked Hans Kmoch to write a parody about him in February 1928 in the Wiener Schachzeitung. This consisted of a mock game against the fictional player "Systemsson", supposedly played and annotated by Nimzowitsch himself. The annotations gleefully exaggerate the idea of overprotection, as well as asserting the true genius of the wondrous idea. Kmoch was in fact a great admirer of Nimzowitsch, and the subject of the parody himself was amused at the effort. Kmoch also wrote an article about his nine years with Nimzowitsch: Nimzovich suffered from the delusion that he was unappreciated and that the reason was malice. All it took to make him blossom, as I later learned, was a little praise. His paranoia was most evident when he dined in company. He always thought he was served much smaller portions than everyone else. He didn't care about the actual amount but only about the imagined affront. I once suggested that he and I order what the other actually wanted and, when the food was served, exchange plates. After we had done so, he shook his head in disbelief, still thinking that he had received the smaller portion. Nimzovitsch's colleague Tartakower observed of him, "He pretends to be crazy in order to drive us all crazy." ++1.E Notable chess games * Friedrich Saemisch vs Aron Nimzowitsch, Copenhagen 1923, Queen's Indian Defence (E18), 0-1 The "Immortal Zugzwang Game" sees Saemisch get tied up in knots. * Paul Johner vs Aron Nimzowitsch, Dresden 1926, NimzoIndian Defence, Rubinstein Variation (E47), 0-1 One of Nimzowitsch's most famous games sees White fall deep into passivity and get squeezed. * Milan Vidmar vs Aron Nimzowitsch, New York 1927, Bogo- Indian Defence (E11), 0-1 A crafty blending of strategy and tactics. * Richard Reti vs Aron Nimzowitsch, Berlin 1928, Nimzo-Indian Defence (E38), 0-1 Two of the top hypermoderns cross swords to showcase their latest ideas. * Efim Bogoljubov vs Aron Nimzowitsch, San Remo 1930, NimzoIndian Defence, Bogoljubov Variation (E23), 0-1 Another encounter of hypermodern heavyweights sees Nimzowitsch with two knights in the endgame, and he handles them perfectly. ++2. Jose Raul Capablanca y Graupera Jose Raul Capablanca y Graupera (November 19, 1888 - March 8, 1942) was a Cuban chess player who was world chess champion from 1921 to 1927. One of the greatest players of all time, he was renowned for his exceptional endgame skill and speed of play. Due to his achievements in the chess world, mastery over the board and his relatively simple style of play he was nicknamed the "Human Chess Machine". ++2.A Biography and career ++2.A1 Childhood Jose Raul Capablanca, the second surviving son of a Spanish army officer, was born in Havana on November 19, 1888. According to Capablanca, he learned the rules of the game at the age of four by watching his father play, pointed out an illegal move by his father, and then beat his father twice. 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 only came fourth out of six in the National Championship, losing both his games against Corzo. In 1905 Capablanca passed with ease the entrance examinations for Columbia University in New York City, where he wished to play for Columbia's strong baseball team, and soon was selected as 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. 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. ++2.A2 Early adult career Capablanca's skill in rapid chess lent itself to simultaneous exhibitions, and his increasing reputation in these events led to a USA-wide tour in 1909. Playing 602 games in 27 cities, he scored 96.4% - a much higher percentage than those of, for example, Giza Marsczy's 88% and Frank Marshall's 86% in 1906. This performance gained him sponsorship for an exhibition match that year against Marshall, the U.S. 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 by 15-8 (8 wins, 1 loss, 14 draws) - a margin comparable to what Emanuel 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 all seven games in the 1910 New York State Championship. After another gruelling series of simultaneous exhibitions, Capablanca placed second, with 9.5 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 Sebastian, Spain, in 1911, insisted that Capablanca also be allowed to play. According to David Hooper and Ken Whyld, San Sebastian 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 presence 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 a score of six wins, one loss and seven draws, ahead of Akiba Rubinstein, Milan Vidmar, Marshall, Carl Schlechter and Siegbert Tarrasch, et al. His loss, against 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. ++2.A3 World title contender In 1911, Capablanca challenged Emanuel Lasker for the World Chess Championship. Lasker accepted his challenge while proposing seventeen conditions for the match. Capablanca objected to some of the conditions, which significantly 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 Capablanca's hometown, 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 further tournament in New York in 1913, at the Rice Chess Club, Capablanca won all thirteen games. In September 1913, Capablanca secured a job in the Cuban Foreign Office, which made him financially secure for life. Hooper and Whyld write that, "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 his games. After arriving 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 played World Champion Emanuel Lasker under normal tournament conditions. This event was arranged in an unusual way: after a preliminary single round-robin tournament involving eleven players, the top five were to play a second stage in double round- robin format, with scores from the preliminary tournament carried forward to the second contest. Capablanca placed first in the preliminary tournament, 1.5 points ahead of Lasker, who was out of practice and made a shaky start. Despite a determined effort by Lasker, Capablanca still seemed on course for ultimate victory. However, 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 Siegbert Tarrasch. Lasker thus finished half a point ahead of Capablanca and 3.5 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 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 pounds Sterling (worth about 347,000 pounds or $700,000 in 2006 terms. ++2.A4 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 Frank James Marshall, playing Black against Capablanca, unleashed a complicated counter-attack, 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 prepared variation. Nevertheless, Capablanca found a way through the complications and won. Capablanca was challenged to a match in 1919 by Borislav Kostic, 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 Kostic resigned the match after losing five straight games. Capablanca considered that he was at his strongest around this time. ++2.A5 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 10.5 points out of 11, one point ahead of Kostic. In January 1920, Emanuel 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 June 27, 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 just fourteen games, having lost four games and won none. Reuben Fine and Harry Golombek attributed the one-sided result to Lasker's being in 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 twenty years younger, a slightly stronger player, and had more recent competitive practice. Edward Winter, after a lengthy summary of the facts, concludes that, "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 only challenger besides Capablanca to win the title without losing a game is Kramnik, in the Classical World Chess Championship 2000 against Garry Kasparov. The score sheet of Capablanca's defeat by Richard Riti in the New York 1924 chess tournament, his first loss in eight years Capablanca won the London tournament of 1922 with 13 points from 15 games with no losses, ahead of Alexander Alekhine on 11.5, Milan Vidmar (11), and Akiba Rubinstein (10.5). 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 2.5 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 (worth about $349,000 in 2006 terms; 20% of the purse was to be paid to the title holder and the remainder divided, 60% going to the winner of the match, and 40% to the loser; the highest purse bid must be accepted. Alekhine, Efim Bogoljubow, Giza Maroczy, Richard Reti, 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 14/20 (+10 -1 =9), 1.5 points behind Emanuel Lasker, and 2 ahead of third-placed Alekhine. Capablanca's defeat at the hands of Richard Reti 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 .5 point behind Emanuel Lasker. Capablanca won at Lake Hopatcong, 1926 with 6 points out of 8, ahead of Abraham Kupchik (5) and Maroczy (4.5). 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 January 1, 1927 to deposit a forfeit in order 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, played from February 19 to March 23, 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 Emanuel Lasker not present. 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; however, he finished undefeated, winning the mini-matches with each of his rivals, 2.5 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, Jose Raul 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. ++2.A6 Losing the title Alekhine vs. Capablanca Since Capablanca had won the New York 1927 chess tournament overwhelmingly and had never lost a game to Alekhine, the Cuban was regarded by most pundits as the clear favorite in their World Chess Championship 1927 match. However, 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 over- confident. 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. Ludek Pachman suggested that Capablanca, who was unused to losing games or to any other type of setback, became depressed over his unnecessary loss of the eleventh game, a long, gruelling endgame, featuring errors by both players. Immediately after winning the match, Alekhine announced that he was willing to give Capablanca a return match, 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. ++2.A7 Post-championship and partial retirement Giving a simultaneous display on thirty boards in Berlin, June 1929 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 would next meet only at the Nottingham, 1936 tournament, after Alekhine had lost the world title to Euwe the preceding 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; although he continued to produce many superb games, he 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. After winning an event at New York in 1931, he withdrew from serious chess, perhaps disheartened by his inability to secure a return match against Alekhine, and played only less serious games at the Manhattan Chess Club and simultaneous displays. 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. ++2.A8 Return to competitive chess At first Capablanca did not divorce his first wife, as he had not intended to re-marry. 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 then married Olga on October 20, 1938, 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 .5 point in the Margate tournaments of 1935 and 1936. At Moscow in 1935 Capablanca finished fourth, 1 point behind the joint winners, while Emanuel 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 3.5 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; Alekhine placed sixth, only one point behind the joint winners. These tournaments of 1936 were the last two that 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 ilite 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. 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, held in Buenos Aires, and won the gold medal for the best performance on the top board. 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. Alekhine also sat out the match when the teams from Cuba and France faced each other in the Buenos Aires Olympiad, thus declining an opportunity to play Capablanca once more. ++2.A9 Final years On March 7, 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 afterwards. He was taken to Mount Sinai Hospital, where he died at 6 a.m. the next morning. The cause of death was given as "a cerebral haemorrhage provoked by hypertension". Capablanca's great rival Emanuel Lasker had died in the same hospital only a year earlier. Capablanca's body was given a public funeral in Havana's Colon Cemetery on March 15, 1942. His bitter rival 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. Emanuel 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. ++2.B Assessment ++2.B1 Playing strength and style As an adult, Capablanca lost only 34 serious games. He was undefeated from February 10, 1916, when he lost to Oscar Chajes in the New York 1916 tournament, to March 21, 1924, when he lost to Richard Reti 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' 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 (2006) 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 fifteen years. Its author, the statistician Jeff Sonas, concluded that Capablanca had more years in the top three than anyone except Lasker, Anatoly Karpov and Garry Kasparov - although Alexander Alekhine had more years in the top two positions. A 2006 study claimed to show that Capablanca was the most accurate of all the World Champions when compared with computer analysis of World Championship match games. However, 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. 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. However, he could play great tactical chess when necessary - most famously in the 1918 Manhattan Chess Club Championship tournament (in New York) where Marshall sprang a deeply-analyzed prepared variation 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. ++2.B2 Influence on the game Capablanca founded no school per se, but his style was very influential in the games of two world champions: Fischer and Anatoly Karpov. Botvinnik also wrote how much he learned from Capablanca, and pointed out that Alekhine had received much schooling from him 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. ++2.B3 Personality Early in his chess career, Capablanca had 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." However 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 false 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 it was correct. 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 the way in which chess had dominated his life, and wished he could have studied music or medicine. ++2.C Capablanca chess 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. However he was concerned that the accelerating development of chess technique and opening knowledge might cause such stagnation in 50 years' time. Hence he suggested the adoption of a 10x8 board with 2 extra pieces per side: * Chancellor - a chancellor that moves as both a rook and a knight; * Archbishop - an archbishop that moves as both a bishop and a knight. This piece would be able to deliver checkmate on its own, which none of the conventional pieces can do. 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 10x10 and 10x8 boards, using the same expanded set of pieces. They preferred the 8-rank 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 10x8 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 (which uses a 10x10 board and has pawns on the third rank), Gothic Chess (which used to be patented), and Embassy Chess (the Grand chess setup on a 10x8 board). ++2.D Notable chess games * Jose Raul Capablanca vs L. Molina, Buenos Aires 1911, Queen's Gambit Declined: Modern. Knight Defense (D52), 1-0 An impressive Greco's sacrifice along with deceptive simplicity and effortless endgame. * Jose Raul Capablanca vs Frank James Marshall, ch Manhattan CC, New York 1918, Spanish Game: Marshall Attack. Original Marshall Attack (C89), 1-0 One of the most famous games of Capablanca. It is on record that Marshall unveiled this attack after careful preparation. Perfect example of defending against an extremely aggressive attack. * Jose Raul Capablanca vs Professor Marc Fonaroff, New York 1918, Spanish Game: Berlin Defense. Hedgehog Variation (C62), 1-0 A freaky ending with amazing accuracy. * Emanuel Lasker vs Jose Raul Capablanca, Lasker-Capablanca World Championship Match, Havana 1921. Queen's Gambit Declined: Orthodox Defense. Rubinstein Variation (D61), 0-1 A strategic masterpiece and instructive endgame which should be on everybody's list. Capablanca out-playing the great Lasker in the endgame with simple and perfect maneuvering of pieces. A must-see game for chess endgame fans. * Jose Raul Capablanca vs Savielly Tartakower, New York 1924, Dutch Defense, Horwitz Variation: General (A80), 1-0 A brilliant endgame from the natural genius. Dubbed as "Rook Before you Leap". Demonstrates the exceptional endgame skills of Capablanca with flawless artistry. * Jose Raul Capablanca vs Rudolf Spielmann, New York 1927, Queen's Gambit Declined: Barmen Variation (D37), 1-0 A remarkable tactical game which earned the "Brilliancy Price" for Capablanca. This is a showcase of Capablanca's tactical skills complementing positional supremacy. * Jose Raul Capablanca vs Andor Lilienthal, Moscow 1936, Reti Opening: Anglo-Slav. Bogoljubow Variation (A12), 1-0 A perfect endgame and pawn play utilizing the space against material advantage. * Ilia Abramovich Kan vs Jose Raul Capablanca, Moscow 1936, Vienna Game: Anderssen Defense (C25), 0-1 Another demonstration of Caplabanca's endgame supremacy. This game seems a drawn game, but witness how Capablanca ekes out a win using his positional mastery. ++2.E Writings * Havana 1913, by Jose Raul Capablanca. This is the only tournament book he wrote.

His only loss was to Rubinstein, and his win against Ossip Bernstein was awarded the brilliancy prize. 1913 New York 1st 11/13 +10 -1 =2 Ahead of Marshall (10.5), Charles Jaffe (9.5) and Dawid Janowski (9). 1913 Havana 2nd 10/14 +8 -2 =4 Behind Marshall (10.5); ahead of Janowski (9) and five others. 1913 New York 1st 13/13 +13 -0 =0 Ahead of Oldrich Duras. 1914 St. Petersburg 2nd 13/18 +10 -2 =6 Behind Emanuel Lasker (13.5); ahead of Alexander Alekhine (10), Siegbert Tarrasch (8.5) and Marshall (8). This tournament had an unusual structure: there was a preliminary tournament in which eleven players played each other player once; the top five players then played a separate final tournament in which each player who made the "cut" played the other finalists twice; but their scores from the preliminary tournament were carried forward. Even the preliminary tournament would now be considered a "super-tournament". Capablanca "won" the preliminary tournament by 1= points without losing a game, but Lasker achieved a plus score against all his opponents in the final tournament and finished with a combined score = point ahead of Capablanca's. 1915 New York 1st 13/14 +12 -0 =2 Ahead of Marshall (12) and six others. 1916 New York 1st 14/17 +12 -1 =4 Ahead of Janowski (11) and 11 others. The structure was similar to that of St. Petersburg 1914. 1918 New York 1st 10.5/12 +9 -0 =3 Ahead of Boris Kostic (9), Marshall (7), and four others. 1919 Hastings 1st 10.5/11 +10 -0 =1 Ahead of Kostic (9.5), Sir George Thomas (7), Frederick Yates (7) and eight others. 1922 London 1st 13/15 +11 -0 =4 Ahead of Alekhine (11.5), Vidmar (11), Rubinstein (10.5), Efim Bogoljubow (9), and 11 other players, mostly very strong. 1924 New York 2nd 14.5/20 +10 -1 =9 Behind Lasker (16); ahead of Alekhine (12), Marshall (11), Richard Riti (10.5) and six others, mostly very strong. 1925 Moscow 3rd 13.5/20 +9 -2 =9 Behind Bogojubow (15.5) and Lasker (14); ahead of Marshall (12.5) and a mixture of strong international players and rising Soviet players. 1926 Lake Hopatcong 1st 6/8 +4 -0 =4 Ahead of Abraham Kupchik (5), Giza Maroczy (4.5), Marshall (3) and Edward Lasker (1.5). 1927 New York 1st 14/20 +8 -0 =12 Ahead of Alekhine (11.5), Aron Nimzowitsch (10.5), Vidmar (10), Rudolf Spielmann (8) and Marshall (6). 1928 Berlin 1st 8.5/12 +5 -0 =7 Ahead of Nimzowitsch (7), Spielmann (6.5) and four other very strong players. 1928 Bad Kissingen 2nd 7/11 +4 -1 =6 Behind Bogojubow (8); ahead of Max Euwe (6.5), Rubinstein (6.5), Nimzowitsch (6) and seven other strong masters. 1928 Budapest 1st 7/9 +5 -0 =4 Ahead of Marshall (6), Hans Kmoch (5), Spielmann (5) and six others. 1929 Ramsgate 1st 5.5/7 +4 -0 =3 Ahead of Vera Menchik (5), Rubinstein (5), and four others. 1929 Carlsbad 2nd= 14.5/21 +10 -2 =9 Behind Nimzowitsch (15); tied with Spielmann; ahead of Rubinstein (13.5) and 18 others, mostly very strong. 1929 Budapest 1st 10.5/13 +8 -0 =5 Ahead of Rubinstein (9.5), Savielly Tartakower (8) and 11 others. 1929 Barcelona 1st 13.5/14 +13 -0 =1 Ahead of Tartakower (11.5) and 13 others. 1929-30 Hastings 1st 6.5/9 +4 -0 =5. 1930-31 Hastings 2nd 6.5/9 +5 -1 =3 Behind Euwe (7); ahead of eight others. 1931 New York 1st 10/11 +9 -0 =2 Ahead of Isaac Kashdan (8.5) and 10 others. 1934-35 Hastings 4th 5.5/9 +4 -2 =3 Behind Thomas, (6.5), Euwe (6.5) and Salo Flohr (6.5); ahead Mikhail Botvinnik (5), Andor Lilienthal (5) and four others. 1935 Moscow 4th 12/19 +7 -2 =10 Behind Botvinnik (13), Flohr (13) and Lasker (12.5); ahead of Spielmann (11) and 15 others, mainly Soviet players. 1935 Margate 2nd 7/9 +6 -1 =2 Behind Samuel Reshevsky (7.5); ahead of eight others. 1936 Margate 2nd 7/9 +5 -0 =4 Behind Flohr (7.5); ahead of Gideon Stehlberg and eight others. 1936 Moscow 1st 13/18 +8 -0 =10 Ahead of Botvinnik (12), Flohr (9.5), Lilienthal (9), Viacheslav Ragozin (8.5), Lasker (8) and four others. 1936 Nottingham 1st= 10/14 +7 -1 =6 Tied with Botvinnik; ahead of Euwe (9.5), Reuben Fine (9.5), Reshevsky (9.5), Alekhine (9), Flohr (8.5), Lasker (8.5) and seven other strong opponents. 1937 Semmering 3rd= 7.5/14 +2 -1 =11 Behind Paul Keres (9), Fine (8); tied with Reshevsky; ahead of Flohr (7), Erich Eliskases (6), Ragozin (6) and Vladimir Petrov (5). 1938 Paris 1st= 8/10 +6 -0 =4 Ahead of Nicolas Rossolimo (7.5) and four others. 1938 AVRO tournament, at ten cities in the Netherlands 7th 6/14 +2 -4 =8 Behind Keres (8.5), Fine (8.5), Botvinnik (7.5), Alekhine (7), Euwe (7) and Reshevsky (7); ahead of Flohr (4.5). 1939 Margate 2nd= 6.5/9 +4 -0 =5 Behind Keres (7.5); tied with Flohr; ahead of seven others.
