Possibly orthogonal, but Churchill's treatment of Blechley Park
offers (offered) many examples of how not to tip one's hand.


His purposeful avoidance of tipping of his hand included
erasing Blechley's history and achievments after the war so
as to avoid having the Soviets realize that the UK was reading
their cables, a story which is detailed in the recent book

The Theory That Would Not Die, Sharon Bertsch McGrayne
