The popular strong PCAC (i.e., pion pole dominance of all Green's functions involving the divergence D of the axial vector current) and good chiral SU(2) x SU(2) symmetry framework has led to many successful predictions. It also, however, leads to some difficulties since, for example, it predicts th
