Query: Strategies for Fixing the CKM-angle $\gamma$ and Obtaining Experimental
  Insights into the World of Electroweak Penguins   Using the $SU(3)$ flavour symmetry of strong interactions, we propose
strategies for extracting both the CKM-angle $\gamma$ and the $\bar b\to\bar
uu\bar s$ tree-level amplitude $T'$. We present also an approximate approach
using the branching ratios for the modes $B^+\to\pi^+ K^0$, $B^0_d\to\pi^-
K^+$, $\bar B^0_d\to\pi^+ K^-$ and $B^+\to\pi^+\pi^0$ which should be rather
promising from the experimental point of view. The quantities $\gamma$ and $T'$
determined this way may well be used as an input to control electroweak
penguins in nonleptonic $B$-decays as has been discussed in previous work.
Following these lines, we propose strategies for obtaining quantitative
insights into the physics of the electroweak penguin operators and performing
some consistency checks. As a by-product, we derive an upper bound of $6^\circ$
for the uncertainty originating from electroweak penguins in the
$\alpha$-determination by means of $B\to\pi\pi$ decays.
