He used his rations to buy Chess Praxis by Danish grandmaster Aron Nimzowitsch, a book which Petrosian would later claim to have had the greatest influence on him as a chess player.

He had a strong affinity for knights rather than bishops, a characteristic that is attributed to the influence of Aron Nimzowitsch.

He had plus scores against Richard Teichmann (+ 6-2 = 6 ), David Janowski (+ 3-1 = 0 ), Carl Schlechter (+ 2-1 = 11 ) and Aron Nimzowitsch (+ 3-2 = 3 ), and level scores with Siegbert Tarrasch and Géza Maróczy.

Nimzowitsch for example delighted in showing how games could be won through indirect control of the center, challenging some of Tarrasch's dogmatic views that the center had to be occupied by pawns.

He had level or nearly level lifetime scores against such outstanding players as the second World Champion Emanuel Lasker (+ 2 − 2 = 1 ), Akiba Rubinstein (+ 1 – 1 = 7 ), Aron Nimzowitsch (+ 1 − 2 = 4 ), Mikhail Chigorin (+ 2 − 1 = 0 ) and Salo Flohr (+ 0 − 0 = 3 ).

The Nimzowitsch Defence is a somewhat unusual chess opening characterised by the moves:

He was a great target of the hypermodern school, led by Richard Réti, Aron Nimzowitsch, and Savielly Tartakower, all of whom criticized his ideas as dogmatic.

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.

Nimzowitsch never developed a knack for match play, though ; his best match success was a draw with Alekhine, but the match consisted of only two games and took place in 1914, thirteen years before Alekhine became world champion.

When in form, Nimzowitsch was very dangerous with the black pieces, scoring many fine wins over top players.

Kmoch also wrote an article about his nine years with Nimzowitsch:

* 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.

Tied for second with 12 points were Aron Nimzowitsch and Rudolf Spielmann.

Favoured by Nimzowitsch, 4 ... b6 is a move in accordance with the spirit of the Nimzo-Indian: Black fianchettoes his light-squared bishop to increase his control over e4.

His highest rank was number six in the world, albeit with a slightly lower rating, in May 1933, behind only Alekhine, Kashdan, Flohr, Capablanca, and Euwe, and ahead of such giants as Aron Nimzowitsch and Akiba Rubinstein.

However, after the end of the First World War, his playing style underwent a radical change, and he became one of the principal proponents of hypermodernism, along with Aron Nimzowitsch and others.

Nimzowitsch advocated controlling the center of the board with distant pieces rather than with pawns, thus inviting the opponent to occupy the center with pawns which can then become objects of attack.

In 1934, he tied for 6th-7th with Aron Nimzowitsch in Zürich ( Alekhine won ).

In 1925, he tied for third / fourth place with Frank Marshall, behind Aron Nimzowitsch and Akiba Rubinstein, in Marienbad.

Larsen's Opening ( also called the Nimzowitsch – Larsen Attack, Nimzo – Larsen Attack, Queen's Fianchetto Opening, Owen's Opening or the Greek Attack ) is a chess opening starting with the move:

White can also transpose to a line of the Nimzowitsch Defence with 3. e4.

Most were about chess, including books on the opening ( Winning Chess Openings ), the middlegame ( 1001 Winning Chess Sacrifices and Combinations ), and game collections ( Great Brilliancy Prize Games of the Chess Masters ), as well as biographies of Alexander Alekhine, José Raúl Capablanca, Paul Keres, Emanuel Lasker ( co-written with Reuben Fine ), Paul Morphy ( Andrew Soltis completed and published this book years after Reinfeld's death ), and Aron Nimzowitsch.

Marshall finished fifth at the St. Petersburg tournament in 1914, behind World Champion Lasker, future World Champions Capablanca and Alekhine, and former World Championship challenger Tarrasch, but ahead of the players who did not qualify for the final: Ossip Bernstein, Rubinstein, Nimzowitsch, Blackburne, Janowski, and Gunsberg.

The same sacrificial pattern was echoed in a number of later games, notably Nimzowitsch – Tarrasch, St Petersburg 1914 ; Miles – Browne, Lucerne 1982 ; and Polgar – Karpov, Seventh Essent 2003.

An acolyte of Siegbert Tarrasch, his sound, strategic play enabled him to defeat a number of the world's top players, including David Bronstein, Aron Nimzowitsch and Milan Vidmar.

Teichmann's records against Emanuel Lasker and Capablanca were poor (+ 0-4 = 0 and + 0-2 = 1 ); however, he scored wins against all the other leading players of his day, e. g. Carl Schlechter (+ 4-2 = 21 ), Frank Marshall (+ 7-7 = 17 ), Aron Nimzowitsch (+ 1-1 = 5 ), Siegbert Tarrasch (+ 5-7 = 2 ), Akiba Rubinstein (+ 5-6 = 11 ), Géza Maróczy (+ 1-2 = 12 ) and David Janowski (+ 4-5 = 4 ).

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.

* Richard Reti vs Aron Nimzowitsch, Berlin 1928, NimzoIndian Defence ( E38 ), 0 – 1 Two of the top hypermoderns cross swords to showcase their latest ideas.

Aron Nimzowitsch ( or Aron Isayevich Nimtsovich, or Aaron Nimzovich ) (, ; born Aron Niemzowitsch ) ( 7 November 1886 – 16 March 1935 ) was a Russian-born, Danish leading chess master and a very influential chess writer.

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.

Nimzowitsch is considered one of the most important players and writers in chess history.

Nimzowitsch supplemented many of the earlier simplistic assumptions about chess strategy by enunciating in his turn a further number of general concepts of defensive play aimed at achieving one's own goals by preventing realization of the opponent's plans.

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 ).

* 1886 – Aron Nimzowitsch, Latvian-born chess player ( d. 1935 )

Ebralidze was a supporter of Nimzowitsch and Capablanca, and his scientific approach to chess discouraged wild tactics and dubious combinations.

This hypermodern opening was developed by Grandmaster Aron Nimzowitsch who introduced it to master-level chess in the early 20th century.

He finished fourth in the very strong St. Petersburg 1914 chess tournament, behind only World Champion Lasker and future World Champions José Raúl Capablanca and Alexander Alekhine, and ahead of Marshall, Ossip Bernstein, Rubinstein, Nimzowitsch, Blackburne, Janowski, and Gunsberg.

Secrets of modern chess strategy: advances since Nimzowitsch.

This plan is named the Hanham Variation ( after the American chess master James Moore Hanham ) and was favoured by Aron Nimzowitsch.

However, this was only part of the Hypermodern framework — which Nimzowitsch encapsulated in the seminal chess work called My System which was to greatly influence many future generations of chess players.

My System () is a book on chess theory written by Aron Nimzowitsch.
