A systematic experimental search for two-body hadronic decays of the b quark of the type b{r_arrow}quark+meson is proposed. These reactions have a well-defined experimental signature and they should be theoretically cleaner compared to exclusive decays. Many modes have appreciable branching ratios, and partial rate asymmetries may also be quite large (about 8{percent} {endash}50{percent} ) in several of them. In a few cases electroweak penguins appear to be dominant and may be measurable. CP -violating triple correlation asymmetries provide a clean test of the standard model. {copyright} {ital 1998} {ital The American Physical Society}
