Rules of golf concerning playing partners? (7)

I believe the answer is:

governs

'rules' is the definition.
(I know this)

'golf concerning playing partners?' is the wordplay.
'golf' becomes 'g' (phonetic alphabet: alpha, bravo, charlie etc.).
'concerning' becomes 'over' (both can mean relating to).
'playing partners?' becomes 'ns' (I've seen this in other clues).
'g'+'over'+'ns'='GOVERNS'

'of' acts as a link.

(Another definition for governs that I've seen is " Rules".)

I've seen this clue in The Telegraph.
