I'm looking for a single word which means "a well thought out action".
In other words, if someone were to plan something carefully, and act on that plan.
For example, a general faces an intractable foe on the battlefield, but thinks carefully on the solution and then acts - defeating the opponent easily. What could we call the action?
N.B. While interesting, I'm not really looking for words which imply "underhanded" or "risky".
