High-precision data for vector and tensor analyzing powers for the {sup 1}H(d-vector,pp)n reaction at a 130-MeV deuteron beam energy have been measured over a large part of the phase space. Theoretical predictions based on various approaches to describe the three nucleon (3N) system reproduce very well the vector analyzing power data and no three-nucleon force effect is observed for these observables. Tensor analyzing powers are also very well reproduced by calculations in almost the whole studied region, but locally certain discrepancies are observed. For A{sub xy} such discrepancies usually appear, or are enhanced, when model 3N forces, TM99 or Urbana, are included. Problems of all theoretical approaches with describing A{sub xx} and A{sub yy} are limited to very small kinematical regions, usually characterized by the lowest energy of the relative motion of the two protons.
