Skill required in case of demands for game in pub (5)
I believe the answer is:
darts
'game in pub' is the definition.
(game often played in pubs)
'skill required in case of demands' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'required in' indicates putting letters inside.
'case of' says to hollow out the word (remove centre letters) (outsides of).
'demands' with its middle taken out is 'ds'.
'art' inserted within 'ds' is 'DARTS'.
'for' acts as a link.
(Other definitions for darts that I've seen before include "Game with arrows and a board" , "Tears" , "They are thrown at targets in pubs" , "Game; moves quickly" , "Game with board and missiles" .)
