Has anyone ever heard of positional theory?

The problem is, I have heard of several different types or views of positional theory, and you did not give enough information to allow me to understand what martial art/field of combat/area of survival/ campaign of war/what you are choosing to talk about. Do you mean angles, angles of attack, angles of reflection, angles of incidence, distance and angle to target, positions of suspects to questioning officers (police), interrogation positions, number theory of logical one to one correspondence between formal proofs of different typologies of numbers, quantum location by designation in space/time of objects that conform to Pauli Exclusion Principle, sex education?
