We propose a new method to extract the CP-violating weak phase γ (the phase of V*ub) in the CKM paradigm of the standard model, using B- → D0π- → fπ- and B- → D̄0π → fπ- decays, where the f's are final states such as K+π-, K+ρ-, Kππ, etc. We also study the experimental feasibility of our new method. With the possibility of new phases in the CKM matrix, we re-examine some of the previously proposed methods to determine γ, and find that it would be in principle possible to identify γ and a new phase angle θ separately.
