P-vortices and drama of Gribov copies

We present results of the careful study of the Gribov copies problem in SU( 2) lattice gauge theory for the direct maximal center projection widely use d in confinement studies. Applying simulated annealing algorithm we demonst rate that this problem is more severe than it was thought before. The proje cted (gauge noninvariant) string tension is not in the agreement with the p hysical string tension, We do not find any indications that P-vortices repr oduce the full SU(2) string tension neither in the infinite volume limit no r in the continuum limit.
