On a quick tangent, I was always under the impression that "Strategy" was your overall plan and "Tactics" were how you carry out that plan. Am I even remotely close in this assumption, or am I way off the mark (or oversimplifying it)?
More or less true, yes.
The best explanation I've heard is strategy is always present or true where as tactics is time-sensitive and dependent on the situation. For example, flanking your enemy and opening a second front is strategy. Standing at the edge of battle and noticing an enemy's weak side and ordering your cavalry to take advantage of it is a tactical move. Hence the two terms are not mutually exclusive and 1UPT adds both.
Controlling the center of the board in chess is good strategy; forking an enemy piece in the middle forcing him to move out and give you control is a tactical move.
Buying low and selling high is strategy. Seeing signs of a price point about to swing the other way and quickly buying/selling to take advantage of it is a tactical move.
