We study the uncertainties of the standard model (SM) predictions for CP violating B decays and investigate where and how supersymmetric (SUSY) contributions may be disentangled. The first task is accomplished by letting the relevant matrix elements of the effective Hamiltonian vary within certain ranges. The SUSY analysis makes use of a formalism which allows one to obtain model-independent results. We show that in some cases it is possible (a) to measure the CP B-- BB mixing phase and (b) to discriminate the SM and SUSY contributions to the CP decay phases. The gold-plated decays in this respect are the B\ensuremath→\ensuremathφKS and B\ensuremath→KS\ensuremathπ0 channels.
