In Chess Praxis Nimzowitsch elaborates on the strategies first adumbrated in My System with a series of deeply annotated games, demonstrating how his principles operated in practice. This was very much a manifesto for the Hypermodern School of Chess which also numbered Hardinge Simpole authors Richard Reti and S.G. Tartakower amongst its ranks.
Aron Nimzowitsch (or Aron Isayevich Nimtsovich, or Aaron Nimzovich; Latvian: Ārons Ņimcovičs, Russian: Аро́н Иса́евич Нимцо́вич; born Aron Niemzowitsch; 7 November 1886 – 16 March 1935) was a Russian-born, Danish leading chess master and a very influential chess writer. He was the foremost figure amongst the hypermoderns.
The book is controversial, several strong players love it. I tried to read it several times. Somehow I did not like his humor, although some of his analogies are really great, like the one where he compared the exchange of a figure which moved several times with an undeveloped figure to pigs: if you had to feed a pig during months, if this pig would die this would be much worst than a young pig. A lot of analogies are related to war, what is not a surprise. My face becomes (•◡•) when I have a look at this book. Really liked it.
Painstakingly detailed practical implementations of hypermodern principles done through extensively annotated games. Read with My System for full benefit
