I present a short guide to recent theoretical achievements and to phenomenological applications in heavy B-meson decays.Extended version of proceedings contribution to ICHEP06, Moscow, July 2006. 6 pages, 3 figures, using ws-procs10x7.cls, a few references addedHigh Energy Physics - Phenomenologytext
