The ratio of partial decay rates for charged and neutral B mesons to K{pi} final states provides information on the weak phase {gamma}{equivalent_to}Arg(V{sub ub}{sup {asterisk}}) when augmented with information on the CP-violating asymmetry in the K{sup {plus_minus}}{pi}{sup {minus_plus}} mode. The requirements for a useful determination of {gamma} are examined in the light of present information about the decays B{sup 0}{r_arrow}K{sup +}{pi}{sup {minus}}, B{sup +}{r_arrow}K{sup 0}{pi}{sup +}, and the corresponding charge-conjugate modes. The effects of electroweak penguin diagrams and rescattering corrections are noted, and proposals are made for estimating and measuring their importance. {copyright} {ital 1998} {ital The American Physical Society}
