Abstract: We start with  the status of the present LHCb anomalies in the  post-R_K* era. These tensions are obscured by still unknown power corrections to these exclusive modes. The method of refactorization  is an option to resolve this problem. Another option is the crosscheck with the corresponding inclusive modes at BELLE-II. The uncertainties due to the nonlocal so-called resolved  contributions are still among the largest ones of these modes. We discuss the alpha_s corrections to these contributions which will reduce their  large scale  and  large charm mass dependence and will significantly increase the new physics sensitivity of the inclusive penguin modes.
