His last name has been spelled in various ways: "Nimzowitsch" or "Niemzowitsch" or "Nimzovitch" or "Nimzovich".
His "My System" book is highly regarded by a lot of chessplayers. I think that it is quite good.
He was one of the leading grandmasters after WW1 and his star shone especially bright after winning the Carlsbad tournament in 1929, but then he finished well behind Alekhine at San Remo in 1930 and Bled in 1931 and most people felt at that point that he had no chance against Alekhine in a World Championship match.
Unfortunately, I don't think he made a lot of money as was the case for many Grandmasters of that time.
Nimzowitsch was not partially Indian---I think he was Jewish-German.
Raymond Keene spells his first name as "Aron".
I don't know but perhaps he lived in Denmark because Germany in the 1920's had anti-semitic politics.
There was no FIDE when Nimzowitsch played chess, hence no rating. FIDE was organized after WW2.
Where was he buried? I would say approximately six feet straight down under the earth's surface.
Just writing...
1) How is his name really spelled correctly ?
Is it Aaron Nimzowitch
2) He wrote a book called My System but i don't understand why he could call it his system when everyone played chess using the same strategy
3) what was his FIDE rating? He had beaten Alekhine and some other dudes but he had not beaten Capablanca. Also he never played any women (probably due to fear) ?
4) The opening Nizmo-Indian defense is named after him? What else did he create ? Was Nimzowitch also partially Indian (native american or India) to include indian in the name of the opening ?
5) what was his salary? did chess players make a lot of money back in the early 1900s ?
6) i think he was german born but why did he move to denmark ?
7) where is he buried and can anybody visit his cemetery?
8) is he a good person to learn from (are his books good and are his games instructive)
thanks
