We consider HQET including the first order correction in 1/m. A strategy for the computation of the bquark mass is discussed. Only two quantities Phi_1/2 have to be considered in order to match QCD and HQET, since the spindependent interaction is easily eliminated due to the spin symmetry of the static theory. Quite simple formulae relate the renormalization group invariant bquark mass (M_b) to the Bmeson mass. All entries in these formulae are nonperturbatively defined and can be computed in the continuum limit of the lattice regularized theory. For the numerically most critical part, we illustrate the cancellation of power divergences by a numerical example. Numerical results for the 1/m correction to M_b, are presented in a companion talk.
