user13674: 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?

user4182: 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.
