   <hidden TTP98-14  Two-loop QCD corrections to semileptonic b decays at an  intermediate recoil > We present complete O(alpha_s^2) corrections to the decay b-->c+l+nu
 at the point where the invariant mass of the leptons sqrt{q^2} equals
 the c quark mass.  We use this result, together with previously
 obtained corrections at the ends of the q^2 spectrum, to estimate the
 total width of the semileptonic b-->c decay with O(alpha_s^2)
 accuracy, essential for the |V_{cb}| determination.
