  I review aspects of chiral dynamics pertinent to the structure of baryons and
few-nucleon systems, such as chiral extrapolations for the nucleon and the
delta mass, double pion photoproduction off protons, single neutral pion
electroproduction off the deuteron, pion photoproduction in the delta region,
the quark mass dependence of the nuclear forces and the possibility of an
infrared limit cycle in QCD.
