Aron Nimzowitsch

Aron Nimzowitsch (Latvian: Ārons Nimcovičs; Russian: Аро́н Иса́евич Нимцо́вич, Aron Isayevich Nimtsovich; 7 November 1886 – 16 March 1935) was a Latvian-born Danish chess player and writer. In the late 1920s, Nimzowitsch was one of the best chess players in the world. He was the foremost figure amongst the hypermoderns and wrote a very influential book on chess theory: My System (1925–1927). Nimzowitsch's seminal work Chess Praxis, originally published in German in 1929, was purchased by a pre-teen and future World Champion Tigran Petrosian and was to have a great influence on his development as a chess player.

Born in Riga, then part of the Russian Empire, the Jewish Yiddish-speaking Nimzowitsch came from a wealthy family, where he learned chess from his father Shaya Abramovich Nimzowitsch (1860, Pinsk – 1918), who was a timber merchant. By 1897, the family lived in Dvinsk. Mother's name: Esphir Nohumovna Nimzowitsch (born Rabinovich, 1865, Polotsk – 1937), sister – Tsilya-Kreyna Pevzner, brothers Yakov, Osey and Benno. In 1904, he travelled 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 Saint 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, where he lived for the rest of his life in one small rented room. In Copenhagen, he won the Nordic Championship twice, in 1924 and in 1934. He obtained Danish citizenship and lived in Denmark until his death in 1935.

The height of Nimzowitsch's career was the late 1920s and early 1930s. Chessmetrics places him as the third best player in the world from 1927 to 1931, behind Alexander Alekhine and José Capablanca. His most notable successes were first-place finishes at Copenhagen 1923, Marienbad 1925, Dresden 1926, Hanover 1926, 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 consisted of only two games and took place in 1914, thirteen years before Alekhine became world champion.

Nimzowitsch never beat Capablanca (+0−5=6), but fared better against Alekhine (+3−9=9). 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 Sämisch 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.

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 Réti, Akiba Rubinstein, Mikhail Botvinnik, Bent Larsen, Viktor Korchnoi 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, although much in this book is generally held to be a rehash of material already presented in Mein System. Mein System is considered to be one of the most influential chess books of all time. 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 accompanied by his idiosyncratic, hyperbolic commentary which is often as entertaining as instructive.
