Abstract

The determination of the angle $\gamma$ of the unitarity triangle of the CKM matrix is a challenge for the $B$-factories. In this context, $B\to\pi K$ decays received a lot of attention, providing various interesting ways to constrain and determine $\gamma$. These strategies are briefly reviewed, and their virtues and weaknesses are compared with one another.
