C[Eric\: e4  is strictly better.  One can check that, since D1,D2,D3 are all available, this gives an edge template + a ladder escape in a way that White can't foil.]

I initially thought this was good, and I still think it wins, but Black had a more-direct win.  See the variation.]

H4 probably also wins for Black, but I can prove this wins for Black, and this is much simpler.]
