I recently played 1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 d5, and it was coded as the Noa variation of the Nimzo-Indian. There was a Josef Noa of Hungary, who lived from, 1856-1903, but his recorded games do not include a Nimzo-Indian, let alone this variation. Why is it named after him then?

    @HerbWolfe The OP wrote "his recorded games do not include a N-I." Do you seriously believe that by "N-I" he meant "Noa"? I don't see why anyone would abbreviate "Noa" at all, much less abbreviate it to "N-I".

  • @bof a simple check of his recorded games does show that he played at least one Nimzo, and it was not a Noa.

  • @HerbWolfe Completely irrelevant. We do not edit other people's posts to correct their facts. You can do that in a comment or an answer, not by putting your words in the OP's mouth.

The Oxford Companion to Chess says that the Noa Variation of the Nimzo-Indian was played regularly by Josef Noa, but that he reached the position after 1.d4 d5 2.c4 e6 3.Nc3 Bb4 4.Qc2 Nf6.


It's probably because he has notable games playing with it or he had analysis published on it.
