We reexamine the question of measuring the weak phase \ensuremathγ in B\ensuremath→K\ensuremathπ\ensuremathπ decays. To this end, we express all B\ensuremath→K\ensuremathπ\ensuremathπ amplitudes in terms of diagrams. We show that, as in B\ensuremath→K\ensuremathπ, relations exist between certain tree and electroweak-penguin diagrams. The imposition of these relations allows the extraction of \ensuremathγ from measurements of the B\ensuremath→K\ensuremathπ\ensuremathπ observables. We estimate the theoretical error in this method to be O(5%).
