Honest work with points (4)
I believe the answer is:
open
'honest' is the definition.
('open' can be similar in meaning to 'honest')
'work with points' is the wordplay.
'work' becomes 'op' (abbreviation for opus).
'with' is a charade indicator (letters next to each other).
'points' becomes 'en' (**).
'op'+'en'='OPEN'
(Other definitions for open that I've seen before include "William --, English poet" , "Sports contest" , "Candid; ajar" , "With which to offer hearty welcome" , "Unenclosed" .)
