  I discuss the dynamics of the two-nucleon system as obtained from a chiral
nucleon-nucleon potential. This potential is based on a modified Weinberg power
counting and contains chiral one- and two-pion exchange as well as four-nucleon
contact interactions. The description of the S-waves is very precise. Higher
partial waves are also well reproduced. We also find a good description of most
of the deuteron properties.
