But I really don't worry about this kind of position, because it is impossible to get such a position against Crafty. I have too much code to encourage development before anything else, so it starts off in a position that could never happen, which means it is probably going to grossly misevaluate it. you might try 14.12 which I tried, which is much closer to reality with the -1.5... but it won't ever understand bizarre positions like this. I would suspect that Nimzo must grossly exaggerate tempi, which in this position gives black a huge plus. But I also suspect that will hurt it in other positions that are perfectly safe but somewhat undeveloped...
