Boastful sort in card game having good skill (8)
I believe the answer is:
braggart
'boastful' is the definition.
(I know that boastful can be written as braggart)
'game having good skill' is the wordplay.
'game' becomes 'brag' (I've seen this before).
'having' is a charade indicator (letters next to each other).
'good' becomes 'g' (abbreviation).
'skill' becomes 'art' (both can mean a talent).
'brag'+'g'+'art'='BRAGGART'
'sort in card' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for braggart that I've seen before include "bigmouth" , "Boastful type" , "Big noter" , "Big boaster" , "Vain boaster" .)
