Recently I have had interest in this program(Nimzo), this I read in the Web of Harald's chess:
"In the reference list for chess programs, the SSDF, Nimzo 8 is even rated lower than its predecessor. I am not able to say if this is true. It is fact that Nimzo 8 shows genious as well as stupid moves but I admit all testing seem to prove that between Nimzo 7.32 and Nimzo 8 there is almost no progress. Nimzo 8 still has no sound evaluation. To get a sound evaluation, other programs should be taken. I must admit that Nimzo is the only program for me without "personality". All other programs obtain some kind of personal character because of the playing style. GambitTiger attacking without compromise, ChessTiger the positional and tactical safe "Karpov", Shredder the strategist. I cannot find it for Nimzo, seems to make moves without a plan or strategy, just fishing. However, since ages the opening book is of highest quality. "
