Adviser or Stategist?

What’s the semantic difference between adviser and strategist?
Hint: In ancient Athens,
the strategi were generals elected by the citizenry to defend the city-state.

“A strategist is someone who has a plan of battle,” observes Joe Pickett,
editor of the American Heritage Dictionary, “and the situation is always one
of contention. There are military and political and investment strategists,
but in all of these cases there is some sort of competitive struggle going on.
Advisers come in more colors. People have spiritual advisers and even
personal advisers. But note that they don’t have spiritual strategists, science
strategists or academic strategists. In these situations there is no other side
to compete with, no one to outfox.”
