Job very much linked to this card game (8)
I believe the answer is:
patience
This clue is a double definition.
'job very much linked to this' is the first definition.
(the biblical figure Job was very patient)
'card game' is the second definition.
(patience is a kind of card game)
(Other definitions for patience that I've seen before include "that one plays" , "Game, tolerance of delay" , "G & S opera" , "bird, some might say" , "restraint" .)
