  After a brief look at the well-known standard approaches to determine the
angle gamma of the unitarity triangle, we focus on two kinds of strategies,
employing $B\to\pi K$ modes, and U-spin-related B decays. Interesting
"puzzles", which may already be indicated by the present B-factory data, are
pointed out, and the importance of the extraction of hadronic parameters, which
are provided by these strategies as by-products, is emphasized.
