Wilhelm Steinitz (14 mai 1836 à Prague, Empire d’Autriche – 12 août 1900 à New York) est un joueur d’échecs autrichien, naturalisé américain en 1888 (à cette occasion il changea officiellement son prénom en William). Il a été le premier champion du monde officiel des échecs de 1886 à 1894, et a, le premier, étudié le jeu d’échecs en profondeur, pour en dégager les règles de stratégie. À ce titre, il est considéré comme le père des échecs modernes.
Steinitz en 1866
Wilhelm Steinitz a approfondi les thèses de Philidor quant aux pions et leur structure. Il en vint à considérer le jeu d’échecs comme une activité se prêtant à une étude scientifique. Se basant sur ses études, il devint un spécialiste des gains de pions qu’il transformait en victoire en finale.
Steinitz, au début de sa carrière, était connu en raison de ses combinaisons brillantes. Son apparition sur la scène échiquéenne en Europe remonte au début des années 1860. Il battit en 1866 l’Allemand Adolf Anderssen (+8 -6). Il est alors considéré comme le meilleur joueur du monde (après la retraite de Paul Morphy en 1860) même si sa supériorité n’est pas incontestable. Sa victoire à Vienne en 1873 et son succès écrasant contre Joseph Henry Blackburne par 7 victoires à 0 en 1874 affirment clairement sa suprématie, notamment sur Anderssen.

Il s’expatria aux États-Unis en 1883 pour y fonder le magazine The International Chess Magazine. Pendant plusieurs années, il y exposa le fruit de ses recherches. Malgré une rigueur certaine, il fit des affirmations que l’expérience réfuta. Par exemple, il considérait le roi comme étant une pièce offensive puissante. Au XXie siècle, cette affirmation est contestée.
Premier champion du monde (1886–1894)
Steinitz fut le premier champion du monde officiel d’échecs en 1886 en battant Johannes Zukertort par 10 victoires à 5 (et 5 nulles). À cette époque, le champion choisissait son challenger et un match en plusieurs parties avait lieu. Il battit deux fois le Russe Mikhail Tchigorine : 10 victoires à 7 et 1 nulle en 1889 et 10 victoires à 8 et 4 nulles en 1892. Entre-temps, il avait battu le Hongrois Isidor Gunsberg (en 1890-1891).
Fin de carrière
Steinitz perdit son titre en 1894 face à Emanuel Lasker par 5 victoires à 10 et 4 nulles et le match revanche, disputé en 1896, fut une défaite écrasante pour l’ancien champion du monde.
Les derniers tournois disputés virent le déclin de plus en plus marquant de Steinitz au fil des années. Il était capable de remporter des victoires brillantes, fruit de l’application de sa conception du jeu, mais les forces physiques lui faisaient de plus en plus défaut. Ainsi lors du tournoi de Londres en 1899, il finit pour la première fois de sa vie hors de la liste des récompensés. Il repartit pour New York où il erra dans les jardins de la ville et mourut dans la plus grande pauvreté.
Le père de la stratégie moderne
Son étude et son jeu marquèrent la fin du style du jeu « attaque à outrance » qui ne respectait pas les règles stratégiques saines. Si le mat était le but final, il n’était pas le seul de la partie. Steinitz a théorisé tout un système de jeu, rassemblant un ensemble de critères pour évaluer une position et ainsi définir les objectifs, le plan à adopter, etc. L’attaque n’était plus seulement le fruit d’une inspiration brillante mais aussi la motivation pour exploiter les faiblesses de la position de l’adversaire. Son jeu défensif était souvent supérieur à celui des joueurs qui recherchaient activement une attaque de mat flamboyante. Steinitz était cependant capable de combinaisons géniales comme le montre sa partie contre Von Bardeleben en 1895.
Steinitz laissa également son nom à plusieurs variantes d’ ouvertures.
- Dans la partie espagnole : 1.e4 e5 2.Cf3 Cc6 3.Fb5 d6 et 1.e4 e5 2.Cf3 Cc6 3.Fb5 a6 4.Fa4 d6 (défense Steinitz différée).
- Dans la défense française : 1.e4 e6 2.d4 d5 3.Cc3 Cf6 4.e5 Cfd7.
Il a même laissé son nom à un gambit réputé douteux dans la partie viennoise : 1.e4 e5 2.Cc3 Cc6 3.f4 exf4 4.d4 ?! Dh4+ 5.Re2 dans lequel il estime que le roi peut se défendre lui-même pourvu que les Blancs conservent leur suprématie centrale.

Earlier dates are debated by commentators
Wilhelm (later William) Steinitz (Prague, May 17, 1836 – August 12, 1900) was an Austrian and then American chess player and the first undisputed world chess champion from 1886 to 1894. From the 1870s onwards, commentators have debated whether Steinitz was effectively the champion earlier. Steinitz lost his title to Emanuel Lasker in 1894 and also lost a rematch in 1897.
Statistical rating systems give Steinitz a rather low ranking among world champions, mainly because he took several long breaks from competitive play. However, an analysis based on one of these rating systems shows that he was one of the most dominant players in the history of the game.
Although Steinitz became « world number one » by winning in the all-out attacking style that was common in the 1860s, he unveiled in 1873 a new positional style of play and demonstrated that it was superior to the previous style. His new style was controversial and some even branded it as « cowardly », but many of Steinitz’s games showed that it could also set up attacks as ferocious as those of the old school. Steinitz was also a prolific writer on chess, and defended his new ideas vigorously. The debate was so bitter and sometimes abusive that it became known as the « Ink War ». By the early 1890s, Steinitz’ approach was widely accepted and the next generation of top players acknowledged their debt to him, most notably his successor as world champion, Emanuel Lasker.
As a result of the « Ink War », traditional accounts of Steinitz’ character depict him as ill-tempered and aggressive; but more recent research shows that he had long and friendly relationships with some players and chess organizations. Most notably from 1888 to 1889 he co-operated with the American Chess Congress in a project to define rules for the future conduct of contests for the world championship title that he held. Steinitz was unskilled at managing money and lived in poverty all his life.
Steinitz in 1866
Steinitz was born on May 17, 1836 in the Jewish ghetto of Prague (now capital of the Czech Republic; then in Bohemia, a part of the Austrian Empire). The last of a hardware retailer’s thirteen sons, he learned to play chess at age 12.  He began playing serious chess in his twenties, after leaving Prague to study mathematics in Vienna,  at the Vienna Polytecnic.  He improved rapidly in the late 1850s, progressing from third place in the 1859 Vienna championship to first in 1861 with a score of 30/31.  In this period he was nicknamed « the Austrian Morphy ». 
Steinitz was then sent to represent Austria in the London 1862 chess tournament. He placed sixth, but his win over Augustus Mongredien was awarded the tournament’s brilliancy prize.  He immediately challenged the fifth-placed contestant, the Italian player Serafino Dubois, to a match, which Steinitz won (five wins, one draw, three losses).  This encouraged him to turn professional and he took residence in London. In 1862-63 Steinitz scored a crushing win in a match with Joseph Henry Blackburne, who went on to be one of the world’s top ten for 20 years but had only started playing chess two years earlier.  Steinitz then convincingly beat most of the leading UK-resident players in matches: Frederic Deacon, Augustus Mongredien, Green, and Robey.  This charge up the rankings had a price: in March 1863 Steinitz apologized in a letter to Ignác Kolisch for not repaying a loan, because while Steinitz had been beating Blackburne, Daniel Harrwitz had « taken over » all of Steinitz’ clients at the London chess club, who had been Steinitz’ main source of income. 
Adolf Anderssen was recognized as the world’s top player until 1866, when Steinitz won a match against him.
These successes established Steinitz as one of the world’s top players, and he was able to arrange a match in 1866 in London against Adolf Anderssen, who was regarded as the world’s strongest active player because he had won the 1851 and 1862 London International Tournaments and his one superior, Paul Morphy, had retired from competitive chess.  Steinitz won with eight wins and six losses (there were no draws), but it was a hard fight; after 12 games the scores were level at 6-6, then Steinitz won the last two games.  As a result of this win Steinitz was generally regarded as the world’s best player.  The prize money for this match was £100 to the winner (Steinitz) and £20 for the loser (Anderssen). The winner’s prize was a large sum by the standards of the times, equivalent to about £57,500 in 2007’s money. 
Steinitz won every serious match he played from 1862 until 1892 inclusive, sometimes by wide margins.  In the years following his victory over Anderssen he beat Henry Bird in 1866 (seven wins, five losses, five draws) and comfortably beat Johannes Zukertort in 1872 (seven wins, four draws, one loss; Zukertort had proved himself one of the elite by beating Anderssen convincingly in 1871).  But it took longer for him to reach the top in tournament play. In the next few years he took: third place at Paris 1867 behind Ignatz Kolisch and Simon Winawer; and second places at Dundee (1868; Gustav Neumann won), and Baden-Baden 1870 chess tournament; behind Anderssen but ahead of Blackburne, Louis Paulsen and other strong players.  His first victory in a strong tournament was London 1872, ahead of Blackburne and Zukertort;  and the first tournament in which Steinitz finished ahead of Anderssen was Vienna 1873,  when Anderssen was 55 years old.
Dominance and controversies
All of Steinitz’ successes up to 1872 inclusive were achieved in the attack-at-all-costs « Romantic » style exemplified by Anderssen. But in the Vienna 1873 chess tournament Steinitz unveiled a new « positional » style of play which was to become the basis of modern chess.  He tied for first place with Blackburne, ahead of Anderssen, Samuel Rosenthal, Paulsen and Henry Bird, and won the play-off against Blackburne. Steinitz made a shaky start but won his last 14 games in the main tournament (including 2-0 results over Paulsen, Anderssen, and Blackburne ) plus the 2 play-off games – this was the start of a 25-game winning streak in serious competition. 
Between 1873 and 1882 Steinitz played no tournaments and only one match (a 7-0 win against Blackburne in 1876). His other games during this period were in simultaneous and blindfold exhibitions,  which contributed an important part of a professional chess-player’s income in those days (for example in 1887 Blackburne was paid 9 guineas for two simultaneous exhibitions and a blindfold exhibition hosted by the Teesside Chess Association;  this was equivalent to about £4,800 at 2007 values ).
Instead Steinitz concentrated on his work as a chess journalist, notably for The Field, which was Britain’s leading sports magazine.  Some of Steinitz’ commentaries aroused heated debates, notably from Zukertort and Leopold Hoffer in The Chess Monthly (which they founded in 1879).  This « Ink War » escalated sharply in 1881, when Steinitz mercilessly criticized Hoffer’s annotations of games in the 1881 Berlin Congress (won by Blackburne ahead of Zukertort). Steinitz was eager to settle the analytical debates by a second match against Zukertort, whose unwillingness to play provoked scornful comments from Steinitz. In mid-1882 James Mason, a consistently strong player,  challenged Steinitz to a match, and accused Steinitz of cowardice when Steinitz insisted the issue with Zukertort should be settled first. Steinitz responded by inviting Mason to name a sufficiently high stake for a match, at least £150 per player (equivalent to about £73,000 in 2007’s money ), but Mason was unwilling to stake more than £100. Mason later agreed to play a match with Zukertort for a stake of £100 per player, but soon « postponed » that match, « circumstances having arisen that make it highly inconvenient for me to proceed … » 
Steinitz’ rival and bitter enemy Johannes Zukertort lost matches to him in 1872 and 1886. The second match made Steinitz the undisputed world champion.
Steinitz’ long lay-off caused some commentators to suggest that Zukertort, who had scored some notable tournament victories, should be regarded as the world chess champion.  Steinitz returned to serious competitive chess in the Vienna 1882 chess tournament, which has been described as the strongest chess tournament of all time at that point. Despite a shaky start he took equal first place with Szymon Winawer, ahead of James Mason, Zukertort, George Henry Mackenzie, Blackburne, Berthold Englisch, Paulsen and Mikhail Chigorin, and drew the play-off match.   While Steinitz was playing in Vienna and sending weekly reports on the tournament to The Field, there was a plot against him back in England. Just after the end of the tournament The Field published a xenophobic article that praised the efforts of the English players and those of English origin in Vienna but disparaged the victory of Steinitz and Winawer. Steinitz stopped working for The Field and was replaced by Hoffer, a close friend of Zukertort and a bitter enemy of Steinitz.  
Steinitz visited the USA, mainly the Philadelphia area, from December 1882 to May 1883. He was given an enthusiastic reception, played several exhibitions, many casual games, a match for stakes of £50 with a wealthy amateur, and slightly more serious matches with two New World professionals, Sellman and the Cuban champion Celso Golmayo Zúpide – the match with Golmayo was abandoned when Steinitz was leading (eight wins, one draw, one loss). His hosts even arranged a visit to New Orleans, where Paul Morphy lived. 
Later in 1883 Steinitz took second place in the extremely strong London 1883 chess tournament behind Zukertort, who made a brilliant start, faded at the end but finished 3 points ahead.  Steinitz finished 2½ points ahead of the third-placed competitor, Blackburne.  Zukertort’s victory again led some commentators to suggest that Zukertort should be regarded as the world chess champion, while others said the issue could only be resolved by a match between Steinitz and Zukertort. 
In 1883, shortly after the London tournament, Steinitz decided to leave England and moved to New York, where he lived for the rest of his life.  This did not end the « Ink War »: his enemies persuaded some of the American press to publish anti-Steinitz articles,   and in 1885 Steinitz founded the International Chess Magazine, which he edited until 1895. In his magazine he chronicled the lengthy negotiations for a match with Zukertort. He also managed to find supporters in other sections of the American press including Turf, Field and Farm and the St. Louis Globe-Democrat, both of which reported Steinitz’ offer to forgo all fees, expenses or share in the stake and make the match « a benefit performance, solely for Mr Zukertort’s pecuniary profit ». 
Eventually it was agreed that in 1886 Steinitz and Zukertort would play a match in New York, St. Louis and New Orleans, and that the victor would be the player who first won 10 games. At Steinitz’ insistence the contract said it would be « for the Championship of the World ».   After the five games played in New York, Zukertort led by 4-1, but in the end Steinitz won decisively by 12½–7½ (ten wins, five draws, five losses). Though not yet officially an American citizen, Steinitz wanted the United States flag to be placed next to him during the match. He became a U.S. citizen on November 23, 1888, having resided for five years in New York, and changed his first name from Wilhelm to William. 
In 1887 the American Chess Congress started work on drawing up regulations for the future conduct of world championship contests. Steinitz actively supported this endeavor, as he thought he was becoming too old to remain world champion – he wrote in his own magazine « I know I am not fit to be the champion, and I am not likely to bear that title for ever ». 
In 1888 Havana Chess Club offered to sponsor a match between Steinitz and whomever he would select as a worthy opponent. Steinitz nominated the Russian Mikhail Chigorin,  on the condition that the invitation should not be presented as a challenge from him. There is some doubt about whether this was intended to be a match for the world championship: both Steinitz’ letters and the publicity material just before the match conspicuously avoided the phrase. The proposed match was to have a maximum of 20 games,  and Steinitz had said that fixed-length matches were unsuitable for world championship contests because the first player to take the lead could then play for draws; and Steinitz was at the same time supporting the American Chess Congress’ world championship project.  Whatever the status of the match, it was played in Havana in January to February 1889 and won by Steinitz (ten wins, one draw, six losses).
The American Chess Congress’ final proposal was that the winner of a tournament to be held in New York in 1889 should be regarded as world champion for the time being, but must be prepared to face a challenge from the second- or third-placed competitor within a month.  Steinitz wrote that he would not play in the tournament and would not challenge the winner unless the second and third placed competitors failed to do so.  The tournament was duly played, but the outcome was not quite as planned: Mikhail Chigorin and Max Weiss tied for first place; their play-off resulted in four draws, and neither wanted to play a championship match – Chigorin had just lost a match against Steinitz and Weiss wanted to get back to his work for the Rothschild Bank. The third prize-winner Isidore Gunsberg was prepared to play Steinitz for the title in New York, and Steinitz won their match in 1890-1891 (six wins, nine draws, four losses).   The American Chess Congress’ experiment was not repeated and Steinitz’ last three world championship matches were private arrangements between the players.  
In 1891 the Saint Petersburg Chess Society and the Havana Chess Club offered to organize another Steinitz-Chigorin match for the world championship. Steinitz played against Chigorin in Havana in 1892 and won narrowly (ten wins, five draws, eight losses). This was his last successful defense of his title. 
Final years of career

Around this time Steinitz publicly spoke of retiring, but changed his mind when Emanuel Lasker challenged him. Initially Lasker wanted to play for $5,000 a side and a match was agreed at stakes of $3,000 a side, but Steinitz agreed to a series of reductions when Lasker found it difficult to raise the money, and the final figure was $2,000 each, which was less than for some of Steinitz’ earlier matches (the final combined stake of $4,000 would be worth about $495,500 at 2007 values. ) Although this was publicly praised as an act of sportsmanship on Steinitz’ part,  Steinitz may have desperately needed the money.  The match was played in 1894, at venues in New York, Philadelphia and Montreal. Steinitz had previously declared he would win without doubt, so it came as a shock when Lasker won the first game. Steinitz responded by winning the second, and was able to maintain the balance until the sixth. However Lasker won all the games from the seventh to the 11th, and Steinitz asked for a one-week rest. When the match resumed, Steinitz looked in better shape and won the 13th and 14th games. Lasker struck back in the 15th and 16th, and Steinitz was unable to compensate for his losses in the middle of the match. Hence Lasker won convincingly with ten wins, five losses and four draws.   Some commentators thought Steinitz’ habit of playing « experimental » moves in serious competition was a major factor in his downfall. 
After losing the title, Steinitz played in tournaments more frequently than he had previously: he won at New York 1894 and was fifth at Hastings 1895 (winning the first brilliancy prize for his game with Curt von Bardeleben); at Saint Petersburg 1895, a four-players round-robin event with Lasker, Chigorin and Pillsbury, he took second place. Later his results began to decline: 6th in Nuremberg 1896, 5th in Cologne 1898, 10th in London 1899.  
In early 1896 Steinitz defeated the Russian Emanuel Schiffers in a match (winning 6 games, drawing 1, losing 4).  In November, 1896 to January, 1897 Steinitz played a return match with Lasker in Moscow but won only 2 games, drawing 5, and losing 10.  This was the last world chess championship match for eleven years. Shortly after the match, Steinitz had a mental breakdown and was confined for 40 days in a Moscow sanatorium, where he played chess with the inmates. 
Joseph Blackburne. Steinitz beat him 7-0 in 1876, but George Alcock MacDonnell hailed Blackburne as « World Champion » for his win in the 1881 Berlin Tournament.
The beginning of Steinitz’s reign
There is a long-running debate among chess writers about whether Steinitz’ reign as World Chess Champion began in 1866, when he beat Anderssen, or in 1886, when he beat Zukertort.   In April 1894 the British Chess Magazine described Steinitz as holding « the chess championship of the world for 28 years ».  However there is no evidence that he claimed the title for himself in 1866, although in the 1880s he claimed to have been the champion since his win over Anderssen.  It has been suggested that Steinitz could not make such a claim while Paul Morphy was alive.  – Morphy had defeated Anderssen by a far wider margin, 8–3, in 1858, but retired from chess competition soon after he returned to the USA in 1859, and died in 1884. The 1886 Steinitz-Zukertort match was the first that was explicitly described as being for the World Championship,  but Howard Staunton and Paul Morphy had been unofficially described as « World Chess Champion » around the middle of the 19th century. In fact one of the organizers of the 1851 London International tournament had said the contest was for « the baton of the World’s Chess Champion », and in mid-1840s Ludwig Bledow wrote a letter to Tassilo von Heydebrand und der Lasa suggesting they should organize a world championship tournament in Germany.  Some commentators described Steinitz as « the champion » in the years following his 1872 match victory against Zukertort. In the late 1870s and early 1880s some regarded Steinitz as the champion and others supported Johannes Zukertort, and the 1886 match was not regarded as creating the title of World Champion but as resolving conflicting claims to the title.  On the other hand George Alcock MacDonnell hailed Joseph Blackburne as « World Champion » for his win in the 1881 Berlin Tournament, George Henry Mackenzie as having « won the Chess Championship of the World » in 1887, and Isidore Gunsberg as « among the champions of the world » following his win at « Bradford Place » in 1888.  However Steinitz regarded G.A. MacDonnell as « one of my bitterest and most untruthful persecutors ». 
Steinitz married a lady named Caroline (born 1846) in the 1860s, and their only daughter Flora was born in 1867.   Flora died in 1888 at the age of 21,  and Caroline died in 1892.  He married his second wife a few years later and had two children by her. However, in 1897 he dedicated a pamphlet to the memory of his first wife and their daughter. 
In February 1897 the New York Times prematurely reported his death in a New York mental asylum.  Some authors claim that he contracted syphilis,  which may have been a cause of the mental breakdowns he suffered in his last years. His chess activities had not yielded any great financial rewards, and he died a pauper in the Manhattan State Hospital (Ward island) of a heart attack on August 12, 1900. Steinitz is buried in the Cemetery of the Evergreens in Brooklyn, New York. His second wife and their two young children were still alive at his death.  Lasker, who took the championship from Steinitz, wrote, « I who vanquished him must see to it that his great achievement, his theories should find justice, and I must avenge the wrongs he suffered. » 
The Field (in London) from 1872 to 1882, and used this to present his ideas about chess strategy.  In 1885 he founded the International Chess Magazine in New York and edited it until 1891. In addition to game commentaries and blow-by-blow accounts of the negotiations leading to his 1886 match with Johann Zukertort and of the American Chess Congress’ world championship project, he wrote a long series of articles about Paul Morphy, who had died in 1884.   He wrote the book of the 1889 New York tournament, in which he commented on all the games,   and in 1889 he published a textbook, The Modern Chess Instructor.

The book of the Hastings 1895 chess tournament, written collectively by the players, described Steinitz as follows: 
- Mr. Steinitz stands high as a theoretician and as a writer; he has a powerful pen, and when he chooses can use expressive English. He evidently strives to be fair to friends and foes alike, but appears sometimes to fail to see that after all he is much like many others in this respect. Possessed of a fine intellect, and extremely fond of the game, he is apt to lose sight of all other considerations, people and business alike. Chess is his very life and soul, the one thing for which he lives.
Influence on the game
Steinitz’ play up to and including 1872 was similar that of his contemporaries: sharp, aggressive, and full of sacrificial play. This was the style in which he became « world number one » by beating Adolf Anderssen in 1866 and confirmed his position by convincingly beating Zukertort in 1872 and winning the 1872 London International tournament (Zukertort had claimed the rank of number two by beating Anderssen in 1871). 
In 1873, however, Steinitz’ play suddenly changed, giving priority to what is now called the positional elements in chess: pawn structure, space, outposts for knights, the advantage of the two bishops, etc. Although Steinitz often accepted unnecessarily difficult defensive positions in order to demonstrate the superiority of his theories, he also showed that his methods could provide a platform for crushing attacks.    Steinitz’ successor as world champion, Emanuel Lasker, summed up the new style as: « In the beginning of the game ignore the search for combinations, abstain from violent moves, aim for small advantages, accumulate them, and only after having attained these ends search for the combination – and then with all the power of will and intellect, because then the combination must exist, however deeply hidden. » 
Although Steinitz’ play changed abruptly, he said had been thinking along such lines for some years: « Some of the games which I saw Paulsen play during the London Congress of 1862 gave a still stronger start to the modification of my own opinions, which has since developed, and I began to recognize that Chess genius is not confined to the more or less deep and brilliant finishing strokes after the original balance of power and position has been overthrown, but that it also requires the exercise of still more extraordinary powers, though perhaps of a different kind to maintain that balance or respectively to disturb it at the proper time in one’s own favor. » 
During his nine-year lay-off from tournament play (1873–1882) and later in his career, Steinitz used his chess writings to present his theories – while in the UK he wrote for The Field;  in 1885 after moving to New York he founded the « International Chess Magazine », of which he was the chief editor;  and in 1889 he edited the book of the great New York 1889 tournament (won by Mikhail Chigorin and Max Weiss),  in which he did not compete as the tournament was designed to produce his successor as World Champion.  Many other writers found his new approach incomprehensible, boring or even cowardly; for example Adolf Anderssen said, » Kolisch is a highwayman and points the pistol at your breast. Steinitz is a pick-pocket, he steals a pawn and wins a game with it. » 
But when he contested the first World Championship match in 1886 against Johannes Zukertort, it became evident that Steinitz was playing on another level. Although Zukertort was at least Steinitz’ equal in spectacular attacking play, Steinitz often out-maneuvered him fairly simply by the use of positional principles.  
By the time of his match in 1890–1891 against Gunsberg, some commentators showed an understanding of and appreciation for Steinitz’ theories.  Shortly before the 1894 match with Emanuel Lasker even the New York Times, which had earlier published attacks on his play and character,   paid tribute to his playing record, the importance of his theories, and his sportsmanship in agreeing to the most difficult match of his career despite his previous intention of retiring. 
By the end of his career Steinitz was more highly esteemed as a theoretician than as a player. The comments about him in the book of the Hastings 1895 chess tournament focus on his theories and writings,  and Emanuel Lasker was more explicit: « He was a thinker worthy of a seat in the halls of a University.

As a result of his play and writings Steinitz, along with Paul Morphy, is considered by many chess commentators to be the founder of modern chess.  Vladmir Kramnik emphasizes Steinitz’ importance as a pioneer in the field of chess theory: « Steinitz was the first to realise that chess, despite being a complicated game, obeys some common principles. … But as often happens the first time is just a try. … I can’t say he was the founder of a chess theory. He was an experimenter and pointed out that chess obeys laws that should be considered. » 
Playing strength and style
 Chessmetrics places him only 15th on its all-time list.  Chessmetrics penalizes players who play infrequently;  opportunities for competitive chess were infrequent in Steinitz’ best years,  and Steinitz had a few long absences from competitive play (1873–1876, 1876–1882, 1883–1886, 1886–1889). However in 2005 Chessmetrics’ author, Jeff Sonas, wrote an article which examined various ways of comparing the strength of « world number one » players, using data provided by Chessmetrics, and found that: Steinitz was further ahead of his contemporaries in the 1870s than Bobby Fischer was in his peak period (1970–1972); that Steinitz had the third-highest total number of years as the world’s top player, behind Emanuel Lasker and Garry Kasparov; and that Steinitz placed 7th in a comparison of how long the great players were ranked in the world’s top three.  Between his victory over Anderssen (1866) and his loss to Emanuel Lasker (1894), Steinitz won all his « normal » matches, sometimes by wide margins; and his worst tournament performance in that 28-year period was third place in Paris (1867).  (He also lost two handicap matches and a match by telegraph in 1890 against Mikhail Chigorin, where Chigorin was allowed to choose the openings in both games and won both )
Initially Steinitz played in the all-out attacking style of contemporaries like Anderssen, and then changed to the positional style with which he dominated competitive chess in the 1870s and 1880s.  Max Euwe wrote, « Steinitz aimed at positions with clear-cut features, to which his theory was best applicable. »  However he retained his capacity for brilliant attacks right to the end of his career; for example in the 1895 Hastings tournament (when he was 59) he beat von Bardeleben in a  His most significant weaknesses were his habits of playing « experimental » moves and getting into unnecessarily difficult defensive positions in top-class competitive games.  
  He admitted that « Like the Duke of Parma, I always hold the sword in one hand and the olive branch in the other »,  and under severe provocation he could become abusive in published articles.  He was aware of his own tendencies and said early in his career, « Nothing would induce me to take charge of a chess column …Because I should be so fair in dispensing blame as well as praise that I should be sure to give offence and make enemies. »  When he embarked on chess journalism, his brutally frank review of Wormald’s « The Chess Openings » in 1875 proved him right on both counts. 
However, his personal correspondence, his own articles and some third-party articles show that he had long and friendly relationships with many people and groups in the chess world, including Ignác Kolisch (one of his earliest sponsors), Mikhail Chigorin, Harry Nelson Pillsbury,  Bernhard Horwitz, Amos Burn  and the Cuban and Russian chess communities.   He even co-operated with the American Chess Congress in its project to regulate future contests for the world title that he had earned. 
Steinitz strove to be objective in his writings about chess competitions and games, for example he attributed to sheer bad luck a poor tournament score by Henry Edward Bird, whom he considered no friend of his,  and was generous in his praise of great play by even his bitter enemies.  He could poke fun at some of his own rhetoric, for example « I remarked that I would rather die in America than live in England. … I added that I would rather lose a match in America than win one in England. But after having carefully considered the subject in all its bearings, I have come to the conclusion that I neither mean to die yet nor to lose the match. »  At a joint simultaneous display in Russia around the time of the 1895-96 Saint Petersburg tournament, Emanuel Lasker and Steinitz formed an impromptu comedy double act. 
Although he had a strong sense of honour about repaying debts,   Steinitz was poor at managing his finances: he let a competitor « poach » many of his clients in 1862-63,  offered to play the 1886 world title match against Johannes Zukertort for free,  and died in poverty in 1900, leaving his widow to survive by running a small shop. 
- Emanuel Lasker regarded this well-prepared attack as a precursor of the positional approach that Steinitz later advocated.
