2000+ CPU core hours went into this using Komodo, Stockfish, Asmfish, and multiple databases. Its been about 2 years since I used this last and figured id release it to the world.
I used some lines from Jan's chess24 study which I would highly recommend for other non-Qc2 Nimzo lines if you are interested. This was a deeper dive off those. I found a few interesting novelties that I wouldn't doubt will come up in serious play in the future. This was mostly reviewed by a couple of 2200+ rated players although some lines didn't get verified.
Please credit me when possible if you share it. It took a lot of time to make. And go check out Jan Gustafsson's work over on chess24.
