Golf's two followers limit what a player can have (8)
I believe the answer is:
handicap
'what a player can have' is the definition.
(as in a handicapped player)
'golf's two followers limit' is the wordplay.
I cannot quite understand how this works, but
'limit' could be 'cap' (capping is a kind of limiting) and 'cap' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for handicap that I've seen before include "Disadvantage imposed on competitor to equalise chances" , "advantage - or the opposite" , "golfer's measure of skill" , "It impedes or hinders" , "Disadvantage to offset an advantage to equalise chances of winning" .)
