We present several schemes of QCD with running coupling with finite value in the infrared (IR). Such couplings, in comparison with usual perturbative couplings with Landau singularities, usually (but not always) contain nonperturbative contributions and, when combined with OPE, better describe IR sector. We then show that evaluation of spacelike renormalization group invariant QCD quantities,...
