Rating all the cards, or just some (8)
I believe the answer is:
deckhand
'just some' is the definition.
I can't judge whether this defines the answer.
'rating all the cards' is the wordplay.
'rating all' becomes 'deck' (I can't explain this - if you can you should believe this answer much more).
'the cards' becomes 'hand' (I've seen this in other clues).
'deck'+'hand'='DECKHAND'
'or' acts as a link.
Can you help me to learn more?
(Other definitions for deckhand that I've seen before include "seaman" , "crew member" , "Ship worker" , "one employed on board?" .)
