In clubs he'd moved slowly (6)
I believe the answer is:
inched
'moved slowly' is the definition.
(I've seen this in another clue)
'in clubs he'd' is the wordplay.
'clubs' becomes 'c' (abbreviation used in card games such as bridge).
'in'+'c'+'hed'='INCHED'
(Other definitions for inched that I've seen before include "Moved by slow degrees" , "Moved gradually" , "Moved along very slowly" , "Moved in small increments" .)
