I have actually focused on this idea recently, and I applied it to my last OTB tournament.
Broadly speaking, I played in such a way as to maximize my options and opportunities, and to minimize my opponents.
When I had move order choices, I played the order that preserved my maximum transpositional opportunities, and which gave my opponent the least useful information as to my future intentions.
As much as possible, I tried to play extremely accurately two moves deep, as I have learned that the vast majority of mistakes in my games (for both sides) involved errors that were only one or two moves deep. (This really worked for me, as in my last tournament two out of my five opponents hung pieces to me before move 20, but they weren't obvious- I had to look a bit to see the error.)
I'm not sure if this is what you are looking for in the thread, but I hope it's a start. I think the question is excellent- it is very fundamental in its focus.
