The starting point (6,3)

I believe the answer is:

square one

'the starting point' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for square one that I've seen before include "Back to . . . . . . . . . - at starting point with no progress made" , "back here after failure" .)

I've seen this clue in The Independent.
