Gambler a cut above (6)
I believe the answer is:
better
I believe this clue is a double definition.
'gambler' is the first definition.
(someone who makes bets is a gambler)
'a cut above' is the second definition.
(thesaurus)
(Other definitions for better that I've seen before include "'Discretion is the . . . . . . part of valour'" , "Surpass; gambler" , "One may lay" , "Gambler; cured" , "More able" .)
