Hi Peter,
I think that black is winning. Here is the analysis (you can save it as PGN and
load into Chessbase). Sorry for the the symbolics in the text, but I analysed
using Chessbase and Nimzo 7.32 so the text represents what is in the PGN-File I
created.

{The idea is to blockade White's pawns and then force Black's b pawn. As White
will be in Zugzwang, he has to give way to black's b pawn. I analyzed this
position using my own chess intuition and checking the lines with a special
Nimzo 7.32 version using 5 piece EGTBs. After that I checked the lines
playing against Hiarcs.} 1... Ke5 2. Ke3 (2. Kd3 Kf4 3. Kc4 Nf7 4. Kb5 Nd6+ (
