I have not nimzo but I expect g3 to fail low because of kasparov's move in the game Rd5(it happens to all the programs that I tried) It will be interesting to know if nimzo can find Ne2. I believe it has a problem to find this move because it overevaluates passed pawns(I say it only based on wastcing games of nimzo and I have not nimzo) but the fact that other moves are bad may force it to find Ne2.
