Nimzo-Indian Defence
Aron Nimzowitsch (Latvian: Ārons Nimcovičs, Russian: Аро́н Иса́евич Нимцо́вич, Aron Isayevich Nimtsovich, 7 November 1886 – 16 March 1935) was a Russian-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 chess player.
